Electric Car Charging Piles. The function of charging piles is like that of tankers in gas stations. Charging piles can be fixed on the ground or wall and installed in public buildings, residential parking lots or public electric car charging stations. They can be used to charge various types of electric cars according to different voltage levels.
AC charging pile. The AC charging pile is also fixedly installed in some public places outside the electric vehicle, and provides a controllable one-way AC power supply or a three-phase AC power supply device for the electric vehicle''s on-board charger. It should be noted that the AC charging post itself does not have a charging function.
