There are two kinds of electric vehicle chargers: AC and DC, the power of AC charger is 7KW, and the power of DC charger is 30, 60, 100, 150, 200KW and other power levels. The following is a specific introduction to electric vehicles: 1. Working principle: through the battery, current, power regulator, electric motor, and power transmission system, the car is driven. 2. Technical principle: pure electric vehicles use electric motors instead of fuel engines, relative to automatic transmissions. The traditional internal combustion engine can limit the speed of efficient torque generation to a narrow range, which is the reason why the traditional internal combustion engine vehicle needs a large and complex transmission mechanism, and the transmission device is not required during the driving of the pure electric vehicle, which is convenient and easy to operate.
