The embodiment of the invention provides a battery thermal management control method, a controller, a battery thermal management system and a vehicle. The method comprises steps of obtaining the current environment temperature of an environment where an electric vehicle is located and the current battery state of a power battery; when the current environment temperature is out of the preset temperature range, correcting a preset battery thermal management control parameter corresponding to the current battery state according to the current environment temperature to obtain a corrected target control parameter; and performing battery thermal management control according to the target control parameter. According to the method, the preset battery thermal management control parameter corresponding to the current battery state is corrected by acquiring the current environment temperature and the battery state of the power battery to obtain the corrected target control parameter, so when the battery thermal management control is carried out according to the target control parameter, battery thermal management control is carried out according to the corrected target control parameter; therefore, the charging and discharging requirements of the battery can be ensured, and the influence on the vehicle safety and the battery safety can be avoided.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method for battery heat management, a controller, a battery heat management system and a vehicle. Background technique [0002] At present, the thermal management strategy of the battery pack is relatively simple, and only the remaining power of the battery (State of Charge, referred to as SOC) and the maximum or minimum temperature are used to formulate the thermal management strategy. [0003] When charging and discharging at high temperature, the maximum temperature of the battery is greater than a certain value, and the maximum charging and discharging power of the battery is limited. If the preset maximum power value is small when the battery is high temperature, it is easy to cause insufficient power in a normal temperature environment; situation, safety cannot be guaranteed. [0004] When charging and discharging at low temperature, if the minimum tem...
