EV high voltage cable sheath and insulation standards and functions

EV high-voltage cables are the nervous system of electric vehicles, and the choice of materials for each structure is critical. The insulation layer of the high-voltage cable mainly plays the role of shielding electromagnetic interference, while the outer sheath of the cable is the outermost layer of the cable and protects the inner core. Common materials for outer sheaths.

The role of the outer sheath of the cable The main function of the outer sheath of the cable is to strengthen the insulation properties while protecting the cable from mechanical damage.

Common materials for cable outer sheath Sheath materials can be divided into metallic materials and non-metallic materials. Metallic materials include copper sheath, aluminum sheath and lead sheath. Non-metallic sheaths include polyvinyl chloride, polyethylene, polypropylene, nylon, fluoroplastics, silicone rubber, neoprene, chlorosulfonated polyethylene, nitrile rubber, low-smoke halogen-free polyolefin, polyurethane, etc.

Regulations of the outer sheath of the cable The jacket is the exterior of the cable. The appearance is required to be smooth and round, with uniform luster, no deviation from the core material (not exceeding the specified deviation), no mechanical damage, flattening, no visible debris, bubbles, trachoma, obvious particles, slub shape, twisted shape, etc. In addition to meeting the above quality requirements, the thickness of the sheath also has a certain influence on the quality of the cable.

Cable outer sheath standard The thickness of the sheath is calculated and controlled according to the standard, and the calculation formula is D (outer diameter before extrusion) × 0.035+1 The thinnest point of the single-core sheath: nominal value × 85%-0.1; The thinnest point of the multi-core sheath: nominal value × 80%-0.2;

The difference between the outer sheath of the cable and the insulating material of the cable The jacket material is mainly used to protect the cable. Used to select sheath material according to external conditions, temperature, humidity, chemical environment, special requirements and other factors. The insulating material mainly protects the conductor insulation. Non-insulating materials and temperature classes are selected based on conductor heating conditions, service life and special requirements.

Differences between EV high voltage cables and EV charging cables

Since the voltage of the high-voltage cable is enough to pose a threat to the human body, the relevant standards stipulate that the color should be orange, which acts as a reminder and warning; but there is generally no requirement for the color of the charging cable.

The environment inside the car is complex. In order to ensure the safety of the car, the high-voltage cable is generally required to meet the wear resistance requirements; while the charging pile cable is often dragged for charging, and generally needs to meet the anti-rolling requirements of the mobile cable.

The ISO organization is responsible for formulating international standards for electric vehicle high-voltage lines; the IEC organization is responsible for the international standards for cable charging.

The high-voltage line of the electric vehicle must be able to withstand various liquids that may be exposed to the vehicle, including oil and water; the charging cable must be able to withstand various liquids in the living environment outside the vehicle.

The charging pile cable has higher requirements for impact resistance and UV resistance due to long-term exposure to the outdoors.

The internal wiring space of the car is small, and the high-voltage cable is fixedly laid. The static bending of each point must be small to be bent and coiled. The charging cable is a mobile laying, and the dynamic bending radius is also required.

In order to facilitate the laying of high-voltage lines of electric vehicles, high-voltage cables are mostly single-core; charging cables are usually multi-core integrated cables, including signal lines, control lines, power auxiliary lines, etc., to ensure accurate control and safety of the entire charging process. run.

The higher the heat resistance of the electric vehicle high-voltage line, the better, the higher the heat resistance, the greater the current carrying capacity, so at least it is required to be able to withstand a high temperature of 125 degrees, and some silicone materials can even reach 180-200 degrees; the charging line is resistant to high temperature The requirements are not so high, the temperature resistance is too high, and it is easy to burn the user.

The structures and materials of the two are also different. High-voltage cables are generally composed of conductors, insulation, shielding, and sheathing, and can have a shielding structure to shield electromagnetic interference; EV charging cables are generally composed of conductors, insulation, fillers, tapes, and sheaths.

Electric vehicle electrical system composition structure

As we all know, electric vehicles rely on electric powered vehicles to drive. On the whole, the high-voltage electrical system includes four major sections, power supply system, drive system, electric equipment and its wiring harness system. Power Systems It is composed of all battery cells inside the car. In the power supply system, all power supply single cores are connected in series and parallel to play a role in safety control. Generally, how much voltage the battery requires for the vehicle is to adjust the voltage value by controlling the number of batteries in series, and the discharge power of the battery is the maximum output capability of the current adjusted by the number of batteries in parallel. Of course, there may be differences in the parameters of the batteries of the corresponding specifications of each manufacturer. In order to ensure safety, the batteries cannot be interchanged. Drive System The drive system is mainly composed of the motor controller and the motor body. The motor controller is responsible for receiving the instructions from the vehicle controller and inverting the power provided by the power system into a form that can be used by the motor. The main body of the motor controller is a power inverter that adjusts the frequency. According to the requirements of the whole vehicle, the motor outputs the speed to the transmission system of the vehicle, so that the wheel speed rotates strictly according to the expectations of the vehicle controller. Electric equipment Electric equipment on electric vehicles includes power steering system, braking system, and air conditioning system. The power steering system consists of a variable frequency drive and a power steering oil pump to assist the vehicle to turn the steering wheel. The braking system is composed of a variable frequency drive and an electric air compressor, which provides compressed air for the braking system and the suspension system to realize the braking function. The air conditioning system is generally equipped with heating and cooling air conditioners in the car, which can adjust the temperature inside the vehicle. Harness system Inside the electric vehicle, the wiring harness system is used to connect the power battery and the high-voltage junction box, the high-voltage junction box and the motor controller, the battery and the engine and other components, as well as the battery energy storage equipment and other fields, as the carrier of power transmission. Generally, the temperature in the car is high, and there are higher requirements for the weather resistance of the cables, and the small space also requires the wiring of the lines. High-voltage cables are an important part of the electrical system of electric vehicles. For more information on EV high-voltage cables, please visit OMG's official website:

Electric vehicle high-voltage wiring harness structure design and its function?

New energy vehicle high-voltage wiring harness is mainly composed of connectors, terminals, cables, coverings and other parts.

Introduction of high-voltage connector standards. At present, connector manufacturers basically refer to the four major European OEMs: Audi, BMW, Daimler, and Porsche jointly developed the industry standard LV series standards; in North America, they mainly implement the relevant standards of SAEuscar, in order to better adapt to More and more HEV requirements, the SAE-USCAR 2 standard was updated in 2008, and the voltage level was raised from the original 20V to 600V. China also has its own high-voltage connector standard: GB standard. In terms of content and standards, there are still many areas that need to be improved.

Introduction to the structure of high-voltage connectors. It is mainly composed of four parts: contacts, insulators, shells and accessories. Among them, the contacts are the core components of the connector to complete the optical and electrical signal connection. The optical and electrical signals required by the vehicle during driving are completed by the insertion of the contacts. The insulator and the shell mainly play the role of fixing, insulating and mechanical protection; the accessories are divided into structural accessories and installation accessories, such as clamps, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, spring rings, etc.

Introduction of high-voltage wire harness crimp terminals. The metal conductor inside the terminal is the core part of the terminal, which transmits the voltage, current or signal from the external wire and cable to the corresponding contact of the corresponding connector. Therefore, the contacts must have excellent structure, stable and reliable contact retention force and good electrical conductivity; the function of the insulator is to keep the contacts in the correct position, and to make the contacts between the contacts and the shell. Insulators are insulated from each other, so the insulating parts must have excellent electrical properties, mechanical properties and process forming properties; the insulator not only acts as insulation, but also provides accurate alignment and protection for the protruding contacts. A feature that is tightly secured to the device. The terminals need to be well fixed to ensure the normal operation of the power transmission and signal control of the control system.

Introduction of high-voltage cables for new energy vehicles. The high-voltage cable material is affected by the environment and function. The temperature near the generator and power battery is high, and there are many corrosive liquids and gases. The cable needs to have high temperature resistance, acid and alkali resistance, corrosion resistance and other properties; the wire on the automatic transmission It needs to have oil resistance, high temperature resistance and other properties; weak signal sensors need to use shielded wires… Automobile wiring harnesses usually use stranded copper wires, and the products need to be flexible, small bending radius, high temperature resistance, acid and alkali resistance, oil resistance, wear resistance, Halogen-free flame retardant and other characteristics, Paige Rui is a manufacturer of energy storage wiring harnesses and new energy electric vehicle wiring harnesses.

Introduction of high voltage wiring harness cover. The covering is mainly divided into corrugated tube and heat shrinkable tube. The temperature resistance level is -40°C-125°C. It needs to meet good elasticity and flexibility, and play a role in insulating and protecting the cable.

Three technical routes for commercial electric vehicle charging solutions

As the electrification of cars, taxis, and buses gains more acceptance, the issue of charging the batteries of electrified vehicles becomes more and more important. Time is money, especially when it comes to logistics vehicles, the first choice is to increase the charging power or allocate idle time for charging. There are mainly three different charging schemes for charging electric logistics vehicles. Scheme 1: Charging method of charging station and fleet operation Charging at charging stations is the best option for local fleet operations, especially buses and transport vehicles. These vehicles operate on relatively fixed routes and are idle during night hours. These charging methods can reduce the demand for charging power and provide more energy management options. These include stationary batteries, and decoupling bus charging time from excess energy is also an option. Charging at charging stations can also act on secondary grid services. Stationary energy storage helps reduce grid load and can also support the grid during periods of high energy demand. Timed charging and load balancing have also become an option. The charging time coincides with the excess energy cycle, which can lead to lower or even negative energy prices at night. A fleet with a fixed schedule does not need to be fully charged at the same time. Energy sharing between vehicles is also possible, and those that are not planned can contribute to energy storage. On the whole, the charging station as a larger industrial area may become a solar power station. Scenario 2: Opportunistic charging Convoys traveling along predetermined routes can extend their driving range by adding small amounts of energy more frequently. This is called "opportunistic charging," and works best if done in a fully automated fashion. There are two recommended solutions for opportunistic charging below. A mechanical system called a pantograph that allows large electrical contacts to travel greater distances and safely make contact with their counterparts. Proven and reliable technology, pantographs can be used in a wide range of tram and rail applications. The pantograph is divided into top-down and bottom-up systems according to the installation location. The bottom-up system is installed on the vehicle and linked to the station. The top-down system is part of the station and descends to the vehicle. The construction of infrastructure is still confined to the roadside. Therefore, such installations can be built to upgrade existing power stations, provided a suitable power supply is available locally. Since these types of situations rarely occur, buffer stations through battery storage are a widely accepted solution to separate high-power charging of vehicles from recharging of stationary batteries. Scenario 3: Long-distance running Due to the need for long-distance logistics, traveling on random routes requires separate high-power charging like today's gas stations. This high-power charging needs to be part of the existing infrastructure to enable seamless integration of electric trucks with the mobility industry. This approach features only a single stage of energy conversion, and replacing the galvanic isolation stage from a smaller single converter to a medium voltage transformer increases the efficiency of the power conversion stage to over 99%. At the same time, the number of resources installed per kW can be minimized, and the space requirement is reduced by the assembly of flat components. When entering the MWh regime, thyristor-based solutions combine superior efficiency with unprecedented longevity and reliability for capsule-type devices.

The era of high-voltage fast charging is coming, OMG charging cables help the development of DC fast charging

With the advent of the era of high-voltage fast charging, the problem of slow charging of electric vehicles is expected to usher in a turnaround. Electric vehicle charging methods can be divided into AC slow charging and DC fast charging. To achieve fast charging, DC fast charging is required. According to P (power) = U (voltage) * I (current), boosting charging power can be divided into two technical routes: boosting voltage and boosting current. The advantage of high voltage is that at the same power: 1) Helps reduce heat generation (according to Q (heat) = I (current) 2R (resistance) t (time)), improve battery safety performance and energy conversion efficiency; 2) It can maintain a long high-rate charging range. Since the charging process is not linear, in the high-current scheme, the charging power cannot maintain the peak value for a long time due to heating problems, so even if the two technical routes of peak power are the same, the average power of high-voltage fast charging is higher; 3) Low rate charging can reduce battery material loss and prolong battery cycle life; 4) The high-current route needs to use a larger diameter cable to carry a larger current, increase the cost and reduce the energy density. However, increasing the voltage requires redesign of components such as the electric drive system and the air conditioner compressor to adapt to the high-voltage platform and eliminate the risk of high-voltage runaway. Taking the Porsche Taycan as an example, in order to adapt to the 800V high voltage, its internal three-electric system has been modified a lot. At the same time, the charging gun, contactor, wiring harness and other components at the charging pile end also need to be upgraded accordingly. Therefore, the early popularization cost of high-voltage fast charging is relatively high, which requires the cooperation of car companies and charging pile infrastructure. High-voltage fast charging significantly shortens the charging time and improves the user's charging experience. High-voltage fast charging is mainly divided into three categories: pure 800V voltage platform, 800V battery pack equipped with DC/DC converter and two 400V low-voltage battery packs. At present, 800V high voltage has become the mainstream of the market. Many domestic and foreign car companies are accelerating the deployment of 800V high voltage fast charging platforms. The charging power of up to 300-500kW can quickly replenish energy in only 6-10 minutes, and the energy replenishment speed is comparable to that of fuel vehicles. Shortening the charging time will significantly improve the travel experience, and the DC charging pile can effectively improve the charging efficiency and help reduce the charging time. Charging piles can be divided into AC charging piles, DC charging piles and AC-DC integrated charging piles according to the charging method. Compared with DC charging piles, AC charging piles require the on-board charger to perform voltage transformation and rectification by itself, which is limited by the power of the on-board charger, which is generally smaller, mostly 3.3 kW and 7 kW. The charging power of DC charging piles is higher, usually 30kW-120kW, which can significantly shorten the charging time. Usually AC charging piles take 8-10 hours to fully charge, and are often used in private home parking spaces; while DC charging piles only take 20-90 minutes to fully charge, so they are mostly used in public parking lots, shopping malls and other scenarios that have high requirements for charging efficiency . OMG is a manufacturer of electric vehicle conductive products - electric vehicle charging cables. With its rich experience and excellent technology, it continuously carries out product innovation and promotes the rapid development of the new energy vehicle industry.

Selection and performance requirements of new energy vehicle wiring harness tape materials

There are three types of tape materials commonly used in new energy vehicle wiring harnesses: PVC tape; cloth tape; sponge tape. The full name of PVC tape is polyvinyl chloride electrical insulating pressure-sensitive adhesive tape. Its base material is soft PVC film, and the viscose is an adhesive layer mainly composed of natural rubber, acrylic adhesive, synthetic rubber, etc. High and low temperature resistance, corrosion resistance, oil resistance, flame retardant and other characteristics. Due to the different auxiliary ingredients, the working temperature range is also different. The commonly used PVC tape has three ambient temperature ranges: -40~85℃, -40~105℃, -40~135℃. Cloth tape is referred to as PET tape. Commonly used cloth tapes include the following types: fiber cloth tape; polyester cloth tape; wool polyester cloth tape; flannel tape; felt tape; electrical insulating waterproof tape; Cloth tape is not flame retardant, the color is usually black, the commonly used specifications are generally 2025, 4025, etc., and the thickness of the tape is generally 0.25~0.8mm. The temperature resistance range is -40~(105℃~150℃). Sponge tape mainly includes: conventional sponge tape, polyurethane sponge tape, flannel sponge tape. It has good shock absorption, noise reduction and water resistance. The tape used in the automotive wiring harness needs to have good temperature resistance, oil resistance, corrosion resistance, flame retardancy, noise reduction, abrasion resistance, low fog and other properties.

Temperature resistance: The low temperature resistance requirement of the wiring harness of the whole vehicle can reach -40°C. The ambient temperature of different positions in the vehicle is different, and the temperature resistance requirements for the tape used for the wiring harness are also different. The ambient temperature in the engine compartment is the highest, so the high temperature resistance of the tape is required in the place closest to the engine.

Oil and corrosion resistance: The working environment of the engine compartment is very complex. Acid, oil and other substances pose a great threat to the wiring harness. The complex working environment will reduce the performance and service life of the tape. Therefore, the engine wiring harness and the engine room wiring harness are used. The tape must have high oil and corrosion resistance.

Flame retardant: Due to the different materials of the tape, the flame retardant performance is also different. It is best to use tape materials with good flame retardant performance for the tape used for the interior wiring harness of the car.

Noise reduction: In the instrument panel wiring harness and the four-door wiring harness, the wiring harness is attached to sheet metal or some hard materials, and some trunk lines or branch lines or even connectors on the wiring harness cannot be completely fixed. The noise generated by the collision of hard materials, in order to enhance the customer experience, the tape used in this part of the wiring harness should preferably have good noise reduction performance.

Wear resistance: The rough surface and sharp edges of the wire harness may scratch the tape, resulting in the loss of insulation protection, bundling, sealing and other properties of the wire harness, and even safety accidents. The tape used in these special locations must have Excellent wear resistance.

Low fog: If the low fog of the wire harness tape does not meet the requirements, when the ambient temperature increases, the substances and odors volatilized from the tape will produce olfactory and visual stimulation to the driver and passengers, enhancing the driver The fatigue resistance increases the probability of safety accidents, so a low-fog tape material should be used.

Do you know the future development trend of new energy electric vehicle wiring harness?

With the increasing demand for new energy vehicles, the requirements for their internal components are also getting higher and higher, and the demand for automotive wiring harnesses as connecting circuit components is also increasing. However, the weight and length of the wiring harness directly lead to an increase in the overall weight of the car, which is not conducive to the interior The wiring also has an adverse effect on the performance of the car. The development of automotive wiring harnesses towards lightweight, structural optimization and production automation is the future trend. Lightweight: The weight of the automobile wiring harness is as high as 50-70KG, reaching 5% of the weight of the whole vehicle, and it is the third heaviest component after the engine and chassis. There are three main ways to realize the lightweight of the wire harness: thinning the conductor insulation layer, miniaturizing the cross section of the wire harness, and using lightweight conductor materials. 1) Ultra-thin-walled wire is a key breakthrough in the miniaturization of conductors, which can significantly and effectively reduce the cross-section, weight and volume of conductors, and make the wire harness lightweight. 2) The alloy wire can significantly reduce the quality and volume of the wire, and the alloy has better bending performance and better tensile strength than pure copper. 3) Replacing copper wires with aluminum wires is one of the methods that everyone agrees to reduce the weight of the wiring harness. Although it can reduce the cost and weight, the conductive effect of aluminum wires is not as good as that of copper, which is a difficult problem that needs to be overcome in the future. Optimization of electronic and electrical architecture: Manufacturers can optimize the wiring harness by simplifying the car circuit design and reducing the wiring in the car, which not only reduces the weight of the wiring harness, but also facilitates the automated production of the wiring harness and reduces the production cost. With the development of electric vehicles towards intelligence, the wiring harness connection in the vehicle is expected to be optimized. Wire harness production automation: The wire harness automated production system can realize automatic gluing, automatic assembly of cable ties, online automatic detection, etc. The efficiency is several times or even ten times that of manual work, which can optimize the cost and efficiency of wire harness production, and promote the automation of production processes. One of the future development trends.

Comparison of charging pile cables and car chargers

At present, there are only two ways to charge electric vehicles. One is to choose home or public charging piles for charging, and the other is to choose the car charger equipped with the car. So what is the difference between the two charging lines?

The car charger can only be used at 220V voltage, and the charging pile cable can be used in charging mode 3 and charging mode 4, involving alternating current and direct current, three-phase power and single-phase power, so the charging range of charging piles is wider. Wide and more efficient charging.

The vehicle charger has a simple structure and convenient control system, but the cables equipped with the charging pile usually need to add signal lines, power auxiliary lines, control lines, etc., so as to precisely control the entire charging process.

As far as the same electric car is concerned, it usually takes several hours to fully charge the car using the on-board charger, but the charging pile is selected for supplementary power, especially the DC fast charging, which is usually 80% full in less than half an hour. All in all, each has its own advantages. The car charger can be placed inside the car for easy use. No matter which charging method you prefer, the most important thing is that the quality of the charging cable is better. OMG is a manufacturer specializing in the production of EV cables.

Introduction of common EV charging connectors

There are many types of connectors on the market today for EV charging and battery life. So how to choose the charging connector that matches the model? Different EV connectors usually vary by region and manufacturer, and are mainly divided into 4 categories. In North America and Japan, the most common EV charging connector on the market is J1772 (Type 1), which only supports single-phase charging. There are 3 main pins to carry current and two other small pins to confirm charging. The type of cable the device connects to the outlet, and the two-way communication between the electric vehicle and the charging system. Commonly found on the European market are Mennekes (Type 2), which can be used for single-phase AC charging and three-phase power. The plug has a 7-hole design with 5 main pins for current transmission and 2 for communication. Connectors made in China have the world's largest electric vehicle market share. They use national standard GB/TEV connectors and are also designed with 7 holes. Tesla, the world's largest electric vehicle company, has a unique set of charging connectors that, unlike all other manufacturers, have the same AC and DC charging connector designs. Only Tesla cars can use this type of DC fast charger, called a supercharger. It uses CAN protocol for bidirectional communication via CP pins.
