The low temperature of the battery cannot complete the normal charging, and heating and electricity can solve the current status of low temperatures that cannot be charged. For A00 (natural wind cold) and PHEV (direct cold scheme), the optimal heating solution of carp electricity is completed with flexible heating membranes, which has been supported by passenger cars such as BAIC EU5, Euler R1, Nezha VPRO, to the Great Wall Wei Series, Chang'an Deep Blue, SAIC Roewe and other PHEV models support
