AI Technical Summary

Technical Problem

Existing power supply control systems are complex in structure, large in size, and have high energy consumption. Furthermore, the construction and maintenance costs of power supply control systems are high, and the flexibility of power supply is limited.

Method used

The system uses an AC auxiliary power supply to draw power directly from an external power source. This power supply is converted from AC/DC to power the signal control circuit and, when needed, also powers the power control circuit. This eliminates the need for a separate auxiliary power supply, simplifies the circuit structure, and reduces size and energy consumption.

Benefits of technology

It greatly simplifies the circuit structure, reduces the system size, lowers energy consumption, improves charging efficiency, and reduces operating costs.

Abstract

This application relates to the field of power technology and discloses a power supply control system, a charging pile, and a power supply control method. The power supply control system does not require a separate auxiliary power supply for the power control circuit and the signal control circuit. It directly draws power from an external power source and supplies power through an AC auxiliary power supply, which greatly simplifies the circuit structure, reduces the size of the power supply control system, significantly reduces system energy consumption, and improves charging efficiency.
