Abstract

The invention discloses a method and device for controlling heating of a battery system. The method comprises receiving a battery preheating instruction which is used for instructing a preheating operation on the battery system of a target electric vehicle and comprises a driving start time when a driver will drive the target electric vehicle next time, responding to the battery preheating instruction to determine a heating start time, which is before the driving start time, for performing the preheating operation on the battery system, detecting whether a current time is up to the heating start time, and turning on a battery heating system to perform the preheating operation on the battery system of the target electric vehicle if the current time is up to the heating start time. The method and device for controlling the heating of the battery system solves the technical problem that the battery system is heated unreasonably in the related art.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a method and device for controlling heating of a battery system. Background technique [0002] The battery system is an important part of new energy vehicles. Under low temperature conditions, the battery system has low discharge capacity, which not only affects the driving performance of the vehicle, but also accelerates the aging of the battery system. The existing technical solution is when the whole vehicle starts and starts to run. , the whole vehicle turns on the thermal management system to heat the battery according to the current temperature. Since electric vehicles are mainly concentrated in cities, the single driving time is relatively short, and it takes a certain amount of time for the battery to heat up to a suitable temperature. As a result, when the driving is over, the battery system is still in a low temperature state, and the low discharge capacity affects the driving ...
