1. The working principle of AC charging gun:
Household AC slow charge, that is, on the basis of the existing residential power supply system (using single-phase 220V or three-phase 380V), the use of 5-10kW power level charger (in fact, it is an AC to DC, the output voltage is not necessarily low), converted into DC, to charge the battery in the car.
2, AC charging gun use precautions
The use of electricity trough as much as possible, can reduce the impact on the grid, but also through the preferential price of peak and valley to reduce the cost of users: this can be solved by timers;
Power can not be too large, charging speed does not need to be fast. Five to eight hours is enough. The capacity of residential lines should be considered.
The charging gun is not only connected to the electric vehicle and the charging pile, but also tied to the safety of the user when charging, as an excellent charging gun enterprise, it is not only necessary to make good charging performance, but also to make an absolutely safe charging gun.
The charging gun should not only be safe and waterproof but also durable in the material, but also have excellent insulation, flame retardant, high temperature resistance and other properties, and then put into production before application, after continuous testing, the performance is qualified before it can be put into use.
The charging gun is a wire, the connected power supply will plug the charging gun into the car for charging, there is a charging and discharging charging module on the car, you can see the current charge on the car, it will show, including that, charging pile, he is also to be charged by the time, according to the charging speed to calculate, the charging gun voltage is relatively high, when plugged in, It will go into Super flash charge
