In some embodiments, the average speed at the current moment may be used to determine the average power consumption of the current driving road section, and the average power consumption and the driving road section are used as basic calculation parameters to calculate the target battery power percentage.

s210: and according to the total electric quantity of the battery, the first detection battery electric quantity percentage and the target battery electric quantity percentage, and the required supplementary electric energy of the vehicle in the traffic jam road section is calculated.
Illustratively, the supplemental electrical energy is calculated according to the following formula:
