Problems solved by technology
[0002] As a representative of new energy vehicles, electric vehicles have become the development trend of future vehicles. Among them, the power battery is the core component that provides power in electric vehicles. The temperature of the power battery will affect the performance of the battery. When the temperature of the power battery is low, the battery capacity Reduced, the discharge current of the battery is small, which will easily cause the vehicle to fail to drive normally, so it is necessary to heat the power battery in a low temperature environment
[0003] At present, electric vehicles usually use a high-power heating device such as a thermistor (Positive Temperature Coefficient, PTC) to provide heat for the power battery, and the heating device needs power from the power battery, which consumes the power of the power battery. When the temperature is low, the discharge current of the power battery is small, and the power is likely to fail to meet the working conditions of the heating device, so that the heating device cannot be started normally, resulting in the power battery not being heated normally
