Abstract

The present disclosure relates to a control method, apparatus and vehicle for a power battery. The method comprises: when the vehicle is powered off, controlling the battery management system of the vehicle to wake up periodically; Detecting a temperature of the power battery when the battery management system is woken up and the vehicle is not in a charged state; When it is determined that the temperature of the power battery is less than a predetermined first temperature threshold, a power battery heating system of the vehicle is activated to heat the power battery. In this way, when the vehicle is stored in a cooler environment, the power battery can be automatically heated to maintain a suitable temperature state to meet the power supply requirements of the vehicle.

Description

technical field [0001] The present disclosure relates to the field of vehicle control, in particular, to a control method and device for a power battery and a vehicle. Background technique [0002] Due to the clean energy and environmental friendliness of electric vehicles, more and more users currently choose electric vehicles or hybrid vehicles for travel. The power battery of an electric vehicle can be used normally under a specific ambient temperature. If the ambient temperature is too low, it will affect the basic charging and discharging functions of the power battery. Electric vehicles are usually equipped with a dedicated power battery heating system to heat the power battery when necessary. [0003] Although the temperature characteristics of the power battery of the current electric vehicle have been greatly improved compared with before, its performance is still greatly affected by low temperature. Contents of the invention [0004] The purpose of the present...
