High-voltage power distribution control system and high-voltage power distribution control method

Abstract

The invention provides a high-voltage power distribution control system and a high-voltage power distribution control method. The high-voltage power distribution control system comprises a battery pack circuit breaking unit which comprises a relay, a fuse, a current sensor and a cooling loop, and the current sensor is used for detecting the current of a battery module; the temperature detection unit is used for detecting the temperature of cooling liquid in the cooling loop and the temperature of an electric connection point of the relay, the fuse and the sensor; and the battery controller is connected with the temperature detection unit and the current sensor, and the battery controller is used for controlling the relay loop, the high-voltage loop and the cooling loop. According to the technical scheme, whether the high-voltage loop is abnormal or not can be judged by integrating the temperature and the current of the cooling liquid and the temperature of the electric connection point of each component, so that the safety of the high-voltage loop is ensured.

Description

technical field [0001] The invention relates to the technical field of high-voltage power distribution, in particular to a high-voltage power distribution control system and a high-voltage power distribution control method.
