As the energy supply device of electric vehicle, the charging performance of electric vehicle charging pile is related to the service life and charging time of the battery pack. This is also one of the most concerned aspects for consumers before purchasing electric vehicles.

If the 7kw charging pile is used for indoor threading, 2.5 cubic meters of BV conductor is enough. If the three-phase current of 7KW is about 14A, the switch can be 25A. If it is single-phase, the current is about 35A, and the air switch should be 40A or above.

The basic principle of electric vehicle charger design is to realize fast, efficient, safe and reasonable power supply for power batteries. In addition, the applicability of the charger to various power batteries should also be considered. The scheme of the charger in the ground charging station. The charger consists of a rectifier that can convert the input AC power into DC power and a power converter that can adjust the DC power of the charger scheme in the ground charging station. By inserting the plug with wire into the supporting socket on the electric vehicle, the DC power is input into the battery to charge it.
