New energy vehicle sales continued to grow strongly in 2023, a year in which major automakers not only made significant breakthroughs in powertrain and battery technology, but also explored in-depth intelligence and internet connectivity.

Background Nowadays, the competition of practical use of solid-state batteries has begun. Toyota, which is leading the way in patents, plans to open trial production EVs within 2021. Volkswagen and Quantum Scape, a Silicon Valley start-up, will start producing batteries that can significantly extend the range of PEV around 2024. Solid-state battery technology is regarded as the next-generation key technology affecting the EV industry.

In new energy vehicles, the motor and power battery are undoubtedly key components, but there is another key device that is easily overlooked - the inverter. Whether it's in models equipped with permanent magnet synchronous motors or three-phase asynchronous motors, the inverter exists as a key component. The reason why the inverter is so important is that the power battery outputs DC power, which must be converted when supplying power to the AC motor.

Under the pressure of cost reduction and efficiency, batteries and system integrators have flocked to larger capacity cells and higher capacity energy storage system tracks. According to different capacities, energy storage cells can be divided into three generations of products, the first generation of 280Ah, the second generation of 300Ah or more energy storage cells, represented by 314Ah capacity.

With the rapid development of microelectronics technology and the improvement of the design level, the integration degree of the chip and the amount of computing data increases significantly, which leads to a sharp increase in the power consumption of the chip.

Solar power systems rely on solar panels to generate electricity, however the inverter is what converts this DC power into usable AC power. The traditional way of generating electricity is to connect the solar panels directly in series, and then connect them to a string inverter, which is connected to the power grid for use by other devices.
