The invention provides a driving heating control method and device.The method comprises the steps that the current environment temperature in the driving process is obtained; according to a preset relational expression, determining a power battery capacity attenuation proportion corresponding to the current environment temperature; wherein the preset relational expression represents the relation between the environment temperature and the battery capacity attenuation proportion; determining a target battery capacity for starting driving heating according to the power battery capacity attenuation proportion; and when the residual battery capacity of the power battery of the electric vehicle is the target battery capacity, driving heating is started. According to the preset relational expression, different power battery capacity attenuation proportions can be obtained at different environment temperatures, and further, the target battery capacity when driving heating is started can be obtained according to the attenuation proportions. In combination with the environment temperature, the starting point of driving heating is dynamically adjusted, and the target battery capacity corresponding to the environment temperature when driving heating is started can be more accurately determined.
Description
technical field [0001] The invention relates to the field of new energy vehicles, in particular to a driving heating control method and device. Background technique [0002] As we all know, the power battery, as the power source of the new energy vehicle, is greatly affected by the ambient temperature. When the ambient temperature is lower than 0°C, the battery capacity of the power battery decays greatly. In order to ensure the cruising range of new energy vehicles, the power battery is generally heated. However, various factors such as battery temperature capacity attenuation, ambient temperature, battery residual power percentage (State Of Charge, SOC) error, heating rate and other factors will affect the judgment of heating the power battery. How to accurately control the heating of the power battery during driving needs to be considered. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a driving heating control method and device ...
