What Is a 21KW Wall-mounted Three-phase AC Charging Pile?

A 21KW Wall-mounted Three-phase AC Charging Pile is a high-power electric vehicle charging device designed to provide efficient AC charging for EVs. It uses a three-phase electrical supply to deliver higher charging power compared with single-phase chargers.

Mounted directly on walls, the charger is compact, space-saving, and ideal for garages, commercial parking lots, apartment buildings, office facilities, and public charging stations.

The 21KW power output allows EV owners to significantly reduce charging time while maintaining stable power transmission and energy efficiency.

How Does a Three-phase AC Charging Pile Work?

The charger connects to a three-phase electrical system and transfers alternating current (AC) to the electric vehicle. The EV’s onboard charger converts AC electricity into direct current (DC) to charge the battery.

Compared with single-phase charging systems, three-phase chargers provide:

• Higher power transmission efficiency
• Faster charging speeds
• Lower energy losses
• Better electrical load balancing
• Improved stability for commercial applications

This makes the 21KW Wall-mounted Three-phase AC Charging Pile ideal for modern EV charging environments.
