The embodiment of the invention discloses a full electric vehicle expanded energy storage system and an electric vehicle with the same. The expanded energy storage system of the pure electric vehicle can comprise an auxiliary energy storage module, a first power distribution module and an auxiliary function driving module, the auxiliary function driving module is electrically connected with the auxiliary energy storage module through the first power distribution module; the auxiliary energy storage module, the first power distribution module and the auxiliary function driving module are all electrically connected to the vehicle control unit; the first power distribution module is electrically connected with a second power distribution module in a main power system of the pure electric vehicle through the power conversion module; and the power supply conversion module is electrically connected with the vehicle control unit. According to the expanded energy storage system of the pure electric vehicle, independent power supply for accessory functions except for a vehicle power system can be achieved, mutual power supplement between the two sets of energy storage systems can be achieved, the driving range of the vehicle can be guaranteed, normal work of the loading function can be guaranteed, and meanwhile the service life of an original vehicle energy storage system can be prolonged.
