The function of the charging pile is similar to the tanker in the gas station, which can be charged for various models of electric vehicles according to different voltage levels.The input end of the charging pile is directly connected to the AC grid. The output end is equipped with a charging plug to charge electric vehicles.
Principle of electric vehicle charging piles
The charging pile is fixed on the ground, using a dedicated charging interface, and using a conduction method to provide AC power for electric vehicles with a vehicle charging motor, which has corresponding communication, billing and security protection functions.
After the electric vehicle battery is discharged, the DC electricity uses the battery in the direction of the opposite of the discharge current to restore the working ability. This process is called the battery charging.When the battery is charged, the battery positive electrode is connected to the power supply positive electrode. The battery negative electrode is connected to the negative electrode of the power supply. The charging power supply voltage must be higher than the total power of the battery.
