BATTERY PACK HEATER AND CONTROL METHOD FOR DUAL-VEHICLE HEATING

Embodiments of the present invention provide a battery pack heating apparatus for double vehicle heating and a control method. In the embodiments of the present invention, portably arranged outside a vehicle, including: an energy storage device; a current sensor; a first diode, an input end of the first diode being connected with a second end of the current sensor; a first heating interface; a first switching device, connected between the second end of the current sensor and a positive electrode of the first heating interface; a second diode, an output end of the second diode being connected with the second end of the current sensor; a second heating interface; a second switching device, connected between the second end of the current sensor and a negative electrode of the second heating interface; a heating control module, configured to control on-off states of the first switching device and the second switching device. Therefore, technical solutions provided by the embodiments of the present invention could solve a problem in the prior art that an indirect heating mode for a single vehicle can only heat one vehicle and heating efficiency is low.
