AI Technical Summary
Technical Problem
In existing technologies, the heating control of power batteries when charging at low temperatures uses a fixed heating threshold, which leads to unnecessary energy waste and low heating efficiency.
Method used
By acquiring the current ambient temperature and charging current of the power battery, the current threshold is dynamically adjusted, and the decision on whether to heat is made based on the current threshold. This avoids the control strategy of fixing the heating threshold and saves energy by utilizing the heat of the power battery itself.
Benefits of technology
It achieves precise control of power battery heating and energy saving, avoids energy waste, and improves charging efficiency.

Abstract
The application provides a power battery heating method and device, electronic equipment, a storage medium and a vehicle. The method determines a current threshold value by obtaining a current ambient temperature of the vehicle, compares a current charging current with the current threshold value, heats the power battery of the vehicle if the current charging current is less than the current threshold value, and stops heating the power battery if the current charging current is greater than or equal to the current threshold value. The application changes the traditional heating control strategy, adopts a current comparison method to determine whether the power battery needs to be heated, can make the heating control strategy of the power battery more accurate, can effectively avoid the problem of energy waste, can fully utilize the heat generated by the power battery during the heating process, and can save the energy consumed by charging and heating.
