Introduction of Home Charging Pile

Introduction of new energy private car charging for household charging piles
Home charging pile new energy private car charging introduction, the self-contained charger used with the car uses the mains (220V), the power input power is limited, and they are charged at home, electric cars are not urgent to use, and can be fully utilized Charging during low power periods reduces the cost of charging; the more important advantage is that the battery can be deeply charged, which improves the battery charging and discharging efficiency and extends the battery life.

The charging pile is a DC charging pile, which is fixedly installed outside the electric vehicle and connected to the AC grid using three-phase alternating current (380V) with a frequency of 50Hz and an adjustable direct current output to directly charge the power battery of the electric vehicle.

Since the DC charging pile adopts a three-phase four-wire system for power supply, it can provide sufficient power, and the output voltage and current can be adjusted in a large range, which can meet the requirements of fast charging. In terms of charging power, the charging pile can be charged according to the maximum power of the on-board charger. This is because the charging pile is to recharge the electric vehicle. The electric vehicle cannot be driven away after waiting for half a day to drive. Ordinary socket equipment can charge the vehicle. Generally, it is about 2~3.5kW; in terms of charging safety, charging piles have leakage, lightning protection, and waterproof functions. Ordinary sockets may not have these protection functions; in addition, charging piles can communicate with the vehicle and can interrupt charging in time if there is a failure High current and high efficiency of the charger require that the charger's own circuit design and manufacturing process must be high, and electric vehicle manufacturers focus on the design and technology of electric vehicles, and will not focus on the charger. That is to say, if the investment is small, the efficiency is naturally low.
