Wireless Charging for EVs: Exploring Innovative Methods and Technologies

With electric vehicles (EVs) gaining traction in the Indian market, enterprises are rapidly upgrading supporting infrastructure to make EV ownership more convenient and encourage broader adoption. This transition not only benefits drivers but also accelerates the shift toward a sustainable, carbon-free energy future.

Charging remains the cornerstone of EV infrastructure, and significant advancements have been made to improve this aspect, including the introduction of wireless electric charging.

Yes, EV owners can now enjoy the convenience of charging their vehicles without plugging them in—similar to wireless phone charging. This innovation brings new levels of efficiency, speed, and uninterrupted transportation, paving the way for a seamless driving experience.

In this blog, we’ll explore the different types of wireless EV charging architectures.

Types of Wireless Electric Charging

Wireless EV charging can be categorized into two main modes: static and dynamic, each offering unique advantages and applications. Let’s dive deeper into these methods and other technologies that make wireless EV charging possible.

1. Static EV Charging (Home or Office Charging Stations)

Static charging systems require the vehicle to remain stationary during charging. Similar to traditional wired charging, these systems use induction to transfer power wirelessly.

When an EV is parked over the designated wireless charging area, transmitters embedded under the asphalt transfer power to the receivers installed beneath the vehicle's chassis. This system is ideal for home garages, office parking lots, and other stationary locations.

2. Dynamic EV Charging (Roadways and Highways)

Dynamic charging takes wireless charging roads a step further by allowing vehicles to charge while in motion. Using mechanisms similar to static systems, dynamic charging operates seamlessly without speed constraints.

This innovation enables EV owners to drive long distances without worrying about depleting battery power. While the concept of dynamic charging roads holds immense promise, building this infrastructure requires significant investment and remains a vision for the future.

Innovative Wireless Charging Systems

Wireless EV charging isn’t limited to static and dynamic methods. Advanced technologies provide a variety of ways to wirelessly transfer energy to EVs:

1. Capacitive Wireless Charging System (CWCS)

In this method, energy is transferred wirelessly via a displacement current generated by an oscillating electric field. Instead of traditional magnets and coils, coupling capacitors facilitate the transfer.

How It Works:

A power factor correction circuit first processes the AC voltage for efficiency and stability.

The voltage is converted to high-frequency AC using an H-bridge, which creates an oscillating electric field.

This field induces displacement current at the receiver, which is then rectified and used to charge the EV battery.

2. Permanent Magnet Gear Wireless Charging System (PMWC)

In the PMWC system, both the transmitter and receiver feature armature windings and synchronized permanent magnets.

How It Works:

The transmitter, acting as a motor, uses AC current to create mechanical torque, rotating its magnet.

This rotation induces synchronous movement in the receiver’s magnet through magnetic interaction.

The receiver generates AC current, which is rectified and converted to DC to charge the EV battery.

3. Inductive Wireless Charging System (IWC)

Inductive charging relies on Faraday's law of induction to transfer power. This method uses mutual induction between transmitter and receiver coils.

How It Works:

An AC magnetic field generated by the transmitter coil induces power in the receiver coil.

The resulting AC output is filtered and rectified to charge the battery.

The efficiency depends on factors like frequency, mutual inductance, and the distance between coils. Inductive systems typically operate between 19 and 50 KHz.

4. Resonant Inductive Wireless Charging System (RIWC)

Resonant inductive systems use high-quality resonators to transmit energy efficiently over longer distances. Maximum power transfer occurs when the resonant frequencies of the transmitter and receiver coils match.

How It Works:

Additional compensation networks (series or parallel) optimize resonant frequency and minimize losses.

These systems operate at frequencies ranging from 10 to 150 KHz, offering higher efficiency for long-distance wireless power transfer.

Wrapping Up

The automotive industry is steadily transitioning to a future where EVs dominate the market. This shift challenges manufacturers to meet strict emission standards and demands the development of robust charging infrastructure.

As the transition from internal combustion engines (ICEs) to EVs unfolds, charging solutions will play a pivotal role in supporting this evolution. wireless charging in electric vehicles, particularly static and dynamic models, are at the forefront of this revolution, offering convenience and efficiency for EV drivers.

At HuseHQ, we are driving this change with cutting-edge wireless charging solutions tailored for homes, offices, and roadways. Our innovative technologies make it easier for facilities, businesses, and residential spaces to transition to an EV-friendly future.

Symptoms of head gasket failure include white smoke from the exhaust, coolant in the oil, and overheating. Regularly checking the engine oil and coolant for signs of contamination and monitoring engine temperature can help detect head gasket issues early. Addressing cooling system problems promptly and ensuring the engine does not overheat are crucial preventative measures. If head gasket failure is suspected, immediate professional intervention is necessary to prevent severe engine damage.

Air Suspension Problems

While not directly related to the engine, air suspension issues can indirectly affect engine performance in used Range Rovers. The air suspension system, designed to provide a smooth ride and adjustable ground clearance, can suffer from leaks, compressor failures, and sensor malfunctions. A failing suspension can lead to increased engine strain as it compensates for uneven ride quality and handling issues. Regularly inspecting the air suspension components, including the airbags, compressor, and sensors, can help detect problems early. Replacing worn or damaged parts and ensuring proper calibration of the suspension system can prevent these issues from affecting overall vehicle performance. If air suspension problems are suspected, professional diagnosis and repair are recommended.

Carbon Build-Up

Carbon build-up is a common issue in direct-injection engines, including those found in used Range Rovers. Over time, carbon deposits can accumulate on the intake valves, leading to reduced airflow, poor fuel economy, and decreased engine performance. Symptoms include rough idling, hesitation during acceleration, and a loss of power. Regular use of high-quality fuel and engine additives designed to clean the intake system can help prevent carbon build-up. Additionally, periodic engine cleaning services, such as walnut blasting, can remove existing deposits and restore engine performance. If carbon build-up is suspected, having the engine inspected and cleaned by a professional can prevent long-term damage and maintain optimal performance.

Conclusion

Owning a used Range Rover can be a rewarding experience, but it's important to be aware of potential engine issues that may arise. Regular maintenance, prompt repairs, and using high-quality parts and fluids can mitigate many of these problems. By understanding the common issues with used Range Rover engines and taking proactive steps to address them, owners can enjoy the luxury and performance these vehicles offer while minimizing the risk of costly repairs.

The Best Skylake-X CPUs Motherboards

TIM gate, VRM disaster? Possible X299 motherboard faults and Skylake-X

In recent weeks, the leaf and video forest has been quiet. Even a VRM disaster or TIM gate (hot paste instead of lot) were discussed, but if you examine closely, the G… Thermal paste instead of solder Intel’s choice of improper (but cheaper) thermal paste instead of indium-based solder contributes to the cooling issue. Discuss the shelf life now… Default Settings Outside the Box, Cheats, Heat Long before launch, motherboard manufacturers made the first critique.

A typical all-in-one compact water cooler has dozens… We hold motherboard makers accountable. Blaming the imminent heat inferno just on Intel and the CPU cranked to its maximum limit would have been too short-sighted.

Noise across all media has been scarce in recent weeks. There was even discussion of a VRM disaster or TIM gate (thermal paste instead of solder), but the whole thing is just a long causal chain that starts with a hot-headed CPU. In theory, there are three. We try to make it simple, so one after another.

(1) Skylake-X is hardly coolable out-of-the-box in typical use due to excessive power consumption and thermal paste that limits optimal heat dissipation.

(2) The average user has little overclocking room, and many motherboards limit the CPU owing to design issues like insufficient external voltage converter cooling. Extreme overclockers barely work with modern hardware.

Usually, too much rhetoric is added, which doesn’t do credit to the potential purchasers’ difficulties.

Test setup and measurements

We’ll acquire a simpler Socket 2066 motherboard, make a vertical benchtable, and test (or not). We’ll look at the sensor values and origins of the respective areas, and we’ll use the infrared thermal imaging camera to test the board’s heating around the socket and voltage converter for plausibility.

We can also record the heating process in time-lapse videos. We also want to know if motherboard hotspots or heat transfer damage other components.

For safe sensor readings and smooth test setup operation, we use the newest motherboard BIOS and HWinfo in the latest beta version from v5.53–3190 (click on beta version while downloading!). We fixed or deepened certain features after a deeper inspection, manufacturer check, and community suggestions.

The board’s CPU power supply has 5 1 phases controlled by an International Rectifier IR35201. This multi-phase buck controller supports Intel VR12 and evidently VR13. The so-called doubling allows two circuits per phase with five phases, relieving the individual VRMs and equalising hotspots in area. This chip’s voltages and currents will be discussed later.

Each control circuit uses one International Rectifier IR3555 voltage converter. These highly integrated power stage chips include gate drivers, high- and low-side synchronous MOSFETs, and the Schottky diode. Unlike other MOSFETs, they have analogue temperature sensors. How else can you accurately measure these voltage converters’ temperatures without an IR camera?

MSI employs the Nuvoton NC6795D as a Super IO chip on the tested motherboard to record and provide sensor information. With a central thermistor between the power stage chips, the voltage converters’ temperature is likewise measured. Thus, we choose the back measuring point below this thermistor for our video acquisition.

The coils and capacitors of these voltage converter circuits and the board temperatures up to the CPU are also checked.

Sudden shutdown and downclocking

To better comprehend the future testing and the concerns that were often addressed too polemically in forums, we must realise that motherboard makers use safety devices. The Skylake-X is clocked down to 1.2 GHz at exactly 105°C at the thermistor (HWinfo under line MOS, Nuvoton NCT6795D) by our test board until the temperature drops below 90°C. Only then does it reach full velocity.

This makes sense since the flash point for the PCB material (FR4) is much higher, but the maximum continuous operating temperature is only between 95 and 105°C to avoid dry-out, bending, and conductor path hairline cracks in multilayer PCBs. This is good because graphics card makers normally have more (unnecessarily) nerve in this area.

In Intel’s Extreme Tuning Utility (XTU), this downclocking termed Thermal Throttling: Yellow, yes. What about Motherboard VR throttling status indicators? We must also give a little addendum regarding HWInfo values. It is less well known that the IR35201 also measures temperature. These results for VR T1 and VR T2 are much higher and appear to contradict the external sensor.

As usual, only the controller chip temperature was output. This would be equivalent to voltage converter temperatures VRM1 and VRM2 on graphics cards with PWM controllers (AMD cards commonly utilised them) in various tools. Usually, the chip measured itself there. However, with IR35201 and IR3555, it can be presumed that the IR3555’s voltage values and temperature inside are also utilised.

Before the XTU yellow warns of motherboard VR throttling, these values are limited to 125°C and the CPU is clocked to 1.2 GHz. Because voltages could run outside specifications and damage hardware above 135°C, the motherboard is turned down without notice.

CPUs also protect themselves. Multiple integrated digital temperature sensors (DTS) determine the computing core and package temperatures. The precision of these calculations rises with temperature. Below 40°C, it’s irrelevant, but from 80°C, it’s accurate. We can also see that core and package temperatures can cause clock throttling.

The power loss of the IVR the CPU’s voltage converters that provide partial voltages is also included in package temperatures. With strong overclocking and manual voltage increase, unanticipated limit overruns might occur quickly, which not all tools can detect. So the CPU throttles without the user knowing why. The IVR will be discussed shortly.

ADAS Sensor Fusion and Data Integration | Dorleco

2. What is Sensor Fusion for ADAS?

ADAS sensor fusion is the process of combining information from various sensors in a car to get a more precise and thorough picture of the environment. Sensor fusion combines data from various sources to create a better depiction of the environment around the vehicle as opposed to depending just on a single sensor, such as a camera or radar. To achieve greater degrees of safety and autonomy, perception must be viewed holistically.

3. Types of Sensors in ADAS

Cameras: In order to identify road markings, traffic signs, pedestrians, and other cars, cameras are a crucial component of ADAS. They provide detailed color information and are especially helpful for lane detection and object recognition.

Radar: Radar sensors use radio waves to gauge an object’s proximity to a moving vehicle by measuring its distance, speed, and direction. They can find items beyond the line of sight and are very useful in bad weather.

LiDAR: Laser beams are used by Light Detection and Ranging (LiDAR) sensors to build a thorough 3D map of the area around the vehicle. LiDAR offers a high-resolution view of the surroundings and is quite accurate at estimating distances.

Ultrasonic Sensors: During low-speed maneuvers, ultrasonic sensors are frequently employed to measure the distance to objects, assist with parking, and give feedback to the driver.

4. Sensor Fusion’s Importance in ADAS

To overcome the limits of individual sensors, sensor fusion, which combines data from several sensors, is essential. Combining the data from many sensor types, each of which has advantages and disadvantages, enables ADAS systems to make more accurate judgments and minimize false positives and negatives.

For instance, although cameras are quite good at identifying objects, they may have trouble in dim light or when there is glare. On the other hand, radar operates effectively in bad weather but lacks the fine detail of cameras. The system can make up for each sensor’s shortcomings by combining the data from both of them, giving a more accurate and robust impression of the environment.

5. ADAS Sensor Fusion Challenges

Sensor fusion has advantages, but there are also big problems to solve. Complex algorithms and powerful computers are needed to integrate data from multiple sensors. The accurate and low-latency real-time processing of enormous volumes of data is a challenging endeavor that calls for advanced computing capabilities.

A good sensor fusion also depends on the calibration and synchronization of the sensors. For reliable data integration and decision-making, all sensors must be precisely synchronized and aligned.

6. ADAS Data Integration

7. ADAS Sensor Fusion and Data Integration Operation

It is possible to generally categorize the ADAS sensor fusion and data integration process into the following steps:

Data collection: Each sensor in the car is constantly gathering information about its surroundings. Ultrasonic sensors measure distances, radar detects things, LiDAR scans the surroundings, and cameras take pictures.

Pre-processing: To eliminate noise, rectify distortions, and provide a standard coordinate system, raw data from sensors is first processed.

Object Detection and Tracking: The system recognizes and follows things in the surroundings using computer vision and machine learning algorithms. Identifying individuals, cars, lane markings, traffic signs, and other important items includes this stage.

Sensor Fusion: After objects are located and tracked, data from all sensors is combined to produce an accurate and complete picture of the surrounding area. This integration aids in removing doubts and ambiguity.

Environmental Perception: Using the combined data, a real-time, comprehensive model of the environment around the vehicle is created. This model includes the locations, velocities, and trajectories of various objects.

Decision-making: The ADAS system decides whether to help the driver or initiate automatic actions, such as changing the vehicle’s speed, steering, or braking to prevent collisions, based on how it perceives the environment.

8. Advantages and Prospects of Sensor Fusion and Data Integration in ADAS

ADAS Sensor Fusion and Data Integration | Dorleco

We may anticipate more complex algorithms and sensors to enable higher levels of autonomy as technology develops, eventually resulting in completely autonomous vehicles. Furthermore, cooperative systems where vehicles can share data with one another and the infrastructure for even greater safety and efficiency will be made possible by the combination of ADAS with Vehicle-to-Everything (V2X) communication.

Conclusion

The automobile industry has undergone a revolution because of ADAS sensor fusion and data integration, which have improved vehicle safety and opened the door for autonomous driving. ADAS can precisely detect the environment, make wise decisions, and efficiently aid drivers by merging data from various sensors and vehicle systems.

We can anticipate a future in which ADAS plays an increasingly important role in developing safer, more intelligent, and more effective mobility solutions for everyone on the road as technology continues to advance.

Signs that Your Car shows Because of a Faulty Alternator

The alternator is an essential part of the charging system of your car. The battery provides the initial power required for the electric starter motor to start the car. And when the car is running, the alternator works to generate electricity for the car's electrical system and also charges the battery. It is attached to the engine and is driven by a serpentine belt. The alternators initially produce AC current which is then converted to DC by the rectifiers. Almost every component of the electrical system gets its power from the alternator. Be it the cooling fans, fuel injection system components, power steering & windows, head lights, wipers, etc. They all depend on the alternator for electrical power. As the alternator is connected to the critical parts of the car, any issue in it can result in the malfunctioning of the parts dependent on it. Here are some of the common signs that your car shows when its alternator loses its potential:

Engine starting issues

One of the first symptoms of a failing alternator is having difficulty in starting the car on a regular basis. It is the duty of the battery to supply the power needed to ignite the spark plugs but to do that comfortably, it needs to remain fully charged for which it hugely depends on the proper functioning of the alternator. So, if there is any problem in the alternator, then along with the disturbance in the supply of power to the electrical accessories of the car, it also fails to keep the battery fully charged. A low charged battery can never meet the high power required to start the car, and when run for a time in such conditions, it turns to be a dead battery.

Flashing of Warning lights

In almost every car, the dashboard consists of a warning light featuring a battery that flashes when the alternator goes out of order. To make the signal clear, it also shows 'ALT' meaning alternator. Do not mistake it for a problem in battery, as it may cause more serious issues. This warning light is linked to the sensors in the car that monitor the voltage output of the alternator. And whenever the alternators output decreases or increases from the minimum requirement, then the sensor system glows the warning light immediately. The average output of the alternator is between 13 to 14.5 volts.  The warning light also pops up when the alternator is overloaded due to the requirement of more power by the headlights, wipers, heated seats, etc. that consume more power. And if your alternator is failing to deliver the right amount of power, then it is required to be replaced to avoid damage to the accessories depending on it for functioning.

Occurrence of Dim lights

The total electrical supply of the car depends on the proper functioning of the alternator in the car. And when the potential of the alternator gets low either due to age or any other factor, then the driver come across several irregularities in the working of the components that directly depends on the power from the alternator. Particularly, the lighting section of the car gets more affected. The headlights which require the highest of power becomes dim, the dash lights also starts fading and the speedometers and tachometers may fail to function. In case the alternator starts malfunctioning in the middle of the road, then quit the use of accessories like radio, seat heaters, A/C, etc. that puts more load on the alternator. Therefore, it is most important to figure out the non-functioning of the alternator as early as possible to avoid such circumstances while driving the car.

Emergence of Weird smells

It is not always good to depend on the warning lights for knowing there is some trouble in the car. While driving, along with your eyes, you also should keep your nose and ear wide open to sense any erratic symptoms in the behavior of the car. The alternator mainly depends on a series of belts for its functioning. Over time, the belts wear out and stop rolling freely which result in excess friction causing the belt to heat up. This excess heat sometimes produces a burning rubber smell. If such burning smell is out there and you feel like there is poor alternator output, then be sure that the serpentine belt isn't in alignment and is slipping on the alternator pulley.

Hearing of Odd sounds

While driving, if along with dim lights, you hear some kind of whining or grinding sounds coming from under the hood, then there is more chance that the alternator is facing any issue. To produce the optimum current, the alternator depends on many parts to spin in a synchronized manner. The alternator pulley typically spins on a shaft which is supported by bearings and bushings. If one of these parts becomes worn or breaks, then it produces the odd sounds. So to avoid such disturbances, the alternator is replaced in a service center to avoid any interruption in the supply of power to all the electrical including the battery.

STMicroelectronics ST-ONE series USD PD controller power increased to 140W

【Lansheng Technology Information】On April 12, 2023, STMicroelectronics launched ST-ONEHP, the first integrated digital controller chip in the industry to pass the USB-IF USB Power Delivery Extended Power Range specification certification.

As the third controller in the ST-ONE series, the ST-ONEHP has an output voltage of 28V, which simplifies the development and design of chargers and power adapters with a maximum rated power of 140W. The converter uses ST-ONE architecture, a non-complementary active clamp flyback zero-voltage switching (ZVS) topology, which ensures excellent energy efficiency for applications with high power output and high switching frequency. The chip integrates basic functions such as secondary rectifier and USB PD communication interface, which saves material cost and PCB size and layout complexity. Built-in synchronous rectifiers help maximize energy efficiency, and reinforced galvanic isolation circuitry allows designers to develop a solution that is both compact and safe.

Inside ST-ONEHP, an Arm® Cortex®-M0+ microcontroller is responsible for the overall control. The microcontroller comes preloaded with certified USB PD firmware, which simplifies the approval process for final product qualification for the USB Logo. The microcontroller has 64KByte flash memory that can store custom power conversion firmware.

The ST-ONEHP is ideally suited for use with STMicroelectronics' MasterGaN chips integrating the company's third-generation gallium nitride (GaN) power transistors and optimized gate drivers in a single package.
