AI Technical Summary

Technical Problem

New energy vehicles are prone to dangerous accidents such as electric arcing, electrical breakdown, and overheating and fire during the charging process, and the charging solution has poor reliability.

Method used

The design employs separate high-voltage and low-voltage plug-in components. The high-voltage line is connected first and then disconnected, while the low-voltage line is disconnected first and then connected. Automatic protection is achieved by combining an electronically controlled relay and a temperature sensor.

Benefits of technology

It improves the safety and reliability of the charging process, preventing circuit failures caused by abnormal plugging/unplugging and loose connectors.

Abstract

A power supply drive circuit, a new energy vehicle, a method, an apparatus, a medium and a product. The power supply drive circuit comprises: a charging plug module; and a charging socket module, which is in charging connection with the charging plug module by means of a high-voltage mating connection assembly; the charging socket module is in control connection with the charging plug module by means of a low-voltage mating connection assembly; the mating connection distance between high-voltage pins and high-voltage slots of the high-voltage mating connection assembly is greater than the mating connection distance between low-voltage pins and low-voltage slots of the low-voltage mating connection assembly. Automatic protection against abnormal connection and removal or loose connection of connectors during power supply is achieved, so as to improve power supply reliability and circuit safety, thereby helping to improve the charging safety of new energy vehicles.
