I did some "New Year's cleaning" this month. Rearranged my bedroom layout and redecorated top shelf in kitchen.
Nothing major, just enough to invite new energy for 2024.

Formula G , a categoria de base da Formula E
A categoria de formação de pilotos para a Formula E, ideia do ex-chefe da Mahindra Racing, Dilbagh Gill, e o Nick Heidefeld Ex –F1, ex- Formula E, inicialmente com o nome ACE Championship , agora Formula G.
A ideia que a categoria tenha quatro campeonatos regionais pelo mundo , na Europa, na Àsia e África ,como acontecem com os campeonatos de Formula 4.
Em cada campeonato terá duas categorias correndo ao mesmo tempo a G-1, e a G-2, com velocidades e potências diferentes, os campeonatos tem a tendência de ter 20 carros e 10 equipes.
A categoria está prevista para começar no fim de 2024.

Basic understanding of battery energy storage system: battery, PCS, BMS
With the increasingly serious global energy crisis and the increasing awareness of environmental protection, energy storage technology has become one of the important means to solve energy problems.
Battery energy storage systems are currently one of the most common and practical energy storage technologies. In the battery energy storage system, the battery, PCS, and BMS are its most basic components. Let’s take a look at these three basic concepts.
Battery
The battery is the core part of the battery energy storage system. It is a device that converts chemical energy into electrical energy. It consists of four parts: positive electrode, negative electrode, electrolyte and separator. There are many types of batteries, the common ones include lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries, etc. Among them, lithium-ion batteries have become the most commonly used battery type in current battery energy storage systems due to their high energy density, long life, and environmental protection.
PCS
PCS is the core equipment in the battery energy storage system. It is a device that converts the electric energy stored in the battery into AC electric energy and supplies it to the grid or users. PCS mainly consists of inverters, transformers, controllers, etc. Its main function is to convert DC power into AC power, control the input and output of power, and ensure the safety and stability of the system. The performance of PCS directly affects the operating efficiency and service life of the battery energy storage system.
BMS
BMS is the abbreviation of battery management system and is an important part of the battery energy storage system. BMS is mainly composed of monitoring module, control module, communication module and other parts. Its main function is to monitor and control the status of the battery in real time, including battery voltage, current, temperature, SOC and other parameters. At the same time, BMS can also protect and control the battery, such as overcharge, over-discharge, over-current, etc., to ensure the safety and life of the battery.
To sum up, batteries, PCS, and BMS are the three basic components of battery energy storage systems. As the core part, the battery is responsible for storing energy; PCS converts the electric energy stored in the battery into AC electric energy; BMS monitors and protects the battery in real time to ensure the safety and life of the battery. In the design and operation of battery energy storage systems, the coordination of the three is crucial. Only in this way can the efficient, stable and safe operation of the battery energy storage system be achieved.
