Abstract

Method (500) performed by an electric vehicle controller (210), in which the vehicle (100) has multiple battery packs (110a, 110b, 110c, 110d), each with its own heating arrangement (230) to individually adjust the respective battery pack temperatures. The method (500) involves detecting when the temperature of the battery packs (110a, 110b, 110c, 110d) falls below a specified lower threshold level. Upon detection, the heating arrangement (230) is allowed to provide heat to a distinct first set (105) of battery packs while being disallowed from providing heat to a separate second set (107) of battery packs. This selective heating strategy occurs when the battery temperature is found to be below the lower threshold level. A corresponding controller (210) and an electric vehicle (100) are also described.
