Abstract

The invention provides a double electric layer package circulation control method, a control system and a vehicle. The double-battery-pack circulation control method comprises the following steps: acquiring electric quantity state information of a first battery pack and a second battery pack; and controlling a range extender to operate based on the electric quantity state information so as to charge the first battery pack or the second battery pack, and controlling another second battery pack or the first battery pack to supply power to a driving motor so as to drive the automobile to operate. According to the double-battery-pack circulation control method, the range extender can be controlled to charge the battery packs by detecting the current state information of the two battery packs in the vehicle, the battery pack which is not charged can drive the vehicle to move, and therefore the two battery packs can be charged one by one to drive the vehicle, and the driving efficiency of the vehicle is improved. The battery pack can be charged in the running process of the vehicle, so that the charging time can be saved, the use efficiency of the battery pack is improved, and the use experience of the vehicle is improved.
