Abstract

The invention provides a battery heating control system for vehicles and a control method thereof. The battery heating control system comprises a heating control module and a battery heating unit; the heating control module is electrically connected with the battery heating unit; the battery heating unit is used for heating a battery; the heating control module is used for starting the heating ofthe battery by the battery heating unit when the condition of heating starting is met and stopping the heating of the battery by the battery heating unit when the condition of heating stop is met, wherein the starting of the battery heating unit meets the following conditions simultaneously that: the ambient temperature K ambient of the system reaches a temperature set value K1; the battery temperature K battery reaches a temperature set value K2; and the battery state of charge (SOC) reaches a set value SOC1 of the battery SOC. The battery heating control system for the vehicles and the control method can better protect the battery.

Description

technical field [0001] The invention belongs to the field of batteries for powering vehicles, and in particular relates to a vehicle battery heating control system and a control method thereof. Background technique [0002] At present, the energy source of hybrid vehicles and electric vehicles is mainly the power battery pack on the vehicle. The power battery pack generally uses lithium batteries. Lithium batteries have become ideal power sources for portable electronic devices and electric vehicles. Considering that the car needs to drive under complex road conditions and environmental conditions, or some electronic equipment needs to be used in poor environmental conditions, the battery used as the power supply of electric vehicles or electronic equipment needs to adapt to these complex conditions, especially when electric When the vehicle or electronic equipment is in a low-temperature environment, the battery needs to have excellent low-temperature charge and discharge p...
