The world is advocating "low-carbon travel", and electric vehicles are developing rapidly. In order to better promote the popularization of electric vehicles, it is necessary to integrate high voltage, high current and complex power conversion, filtering and charging management systems to narrow the gap. EV charging cables are also required to match the charging piles for charging and supplementing electric vehicles.

At present, the difference in charging electric vehicles is whether to use DC charging piles for charging or AC charging piles. DC charging piles are also called fast charging piles, and the charging speed is fast; AC charging piles are slow charging piles, and the charging speed is slower. Since car batteries must be powered by direct current, and the electricity in the grid is alternating current, some vehicles use single-phase or three-phase AC on-board chargers, which are then rectified to suitable direct current.

In addition to the faster charging speed of the AC pile, the conversion cost of DC charging is borne by the operator of the DC charging network, and the AC power is borne by the owner of the electric vehicle charging. Some charging standards allow two-way charging between vehicles and the grid, so electric vehicles can be used as distributed power sources to send electricity back to the grid during peak power consumption, which is conducive to the stable operation of the grid.

Of course, long-term high-frequency fast charging will damage the car battery, so the choice of fast charging pile and slow charging pile depends on the owner of the car.
