Embodiment Construction

[0069] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0070] Embodiments of the present disclosure provide a vehicle battery pack heating method, such as figure 1 shown, including:

[0071] Step S11, obtaining a preset reference time.

[0072] Specifically, the reference time may be the time set by the user to start the vehicle function related to the use of the battery pack, for example, it may be the reserved vehicle charging time, in this case, the user can use the display screen of the vehicle or the The mobile terminal inputs the charging time of the vehicle, and the vehicle can obtain the charging time of the vehicle through the controller.

[0073] For example, the reference time can also be the reserved vehicl...

Abstract

The present disclosure relates to a vehicle battery pack heating method and system, and a battery manager. The heating method includes: acquiring a preset reference time; determining a real-time temperature value of the battery pack and a target temperature value of the battery pack to determine Before the reference time, the starting time of heating the battery pack; when the current time of the vehicle reaches the starting time, the heating of the battery pack is started, so that the temperature value of the battery pack is The target temperature value is reached before the reference time is reached. Through the above technical solution, the battery pack can be automatically heated before the reference time when the battery pack needs to be charged or discharged, so that when the reference time is reached, the temperature of the battery pack can meet the usage requirements, thereby improving the use of the vehicle. efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a method and system for heating a battery pack of a vehicle, and a battery manager. Background technique [0002] With the continuous development of science and technology, vehicle technology has also been continuously developed, and more and more electric vehicles appear in people's daily life. The power of electric vehicles is usually provided by battery packs. At present, the power batteries of electric vehicles are generally lithium-ion batteries. The electrolyte used in lithium batteries is an organic liquid, which will become viscous or even condense at low temperatures. As a result, the efficiency of the lithium battery is low. At this time, the activity of the lithium salt used for conduction in the battery pack is greatly restricted, which reduces the charging efficiency of the battery pack, and finally leads to the slow charging of the battery pack at low...
