Problems solved by technology

[0006] Embodiments of the present invention provide an over-temperature protection control method and device for a battery cell of a vehicle, a battery pack, a vehicle, and a readable storage medium, aiming to solve the problem of consuming a large amount of battery power when periodically waking up the over-temperature protection control system in the related art This further leads to the technical problem of battery power feeding. The over-temperature protection control system can be awakened only when the temperature is too high, which reduces the power consumption of the battery by the over-temperature protection control system.

Abstract

The invention provides an over-temperature protection control method and device, a battery pack, a vehicle and a readable storage medium. The method is used for controlling an over-temperature protection control system of a battery cell of the vehicle, and comprises the steps of: acquiring a cell temperature in a vehicle power battery module in the battery pack when the over-temperature protectioncontrol system of the battery pack is in a dormant state; and outputting a start signal to the over-temperature protection control system in response to fact that the cell temperature exceeds a predetermined temperature threshold. Through the technical solution, the number of times of awakening the over-temperature protection control system and the working duration of the over-temperature protection control system are greatly reduced, thereby reducing the battery power consumed by the over-temperature protection control system, reducing the possibility of feed when the over-temperature protection control system consumes too much power and further improving the safety of the vehicle power battery.

Description

【Technical field】 [0001] The present invention relates to the technical field of batteries, in particular to an over-temperature protection control method and device for vehicle battery cells, a battery pack, a vehicle and a readable storage medium. 【Background technique】 [0002] When a vehicle with a power battery is parked, the internal temperature of the battery pack of the power battery will rise due to reasons such as high ambient temperature, which will lead to overheating of the battery, affecting the performance and life of the battery, and even thermal runaway. Serious consequences will affect the safety of the vehicle. [0003] Since the battery management system is in a dormant state in the parking state, it is impossible to check the temperature in the battery pack. For this, the related technology proposes to use the battery management system as an over-temperature protection control system and periodically wake up the battery management system. To monitor the...
