Since the discharge current of the energy storage 2 is larger than the output current of the on-board power supply, the energy storage 2 can quickly supply a large amount of energy to the heating mat 4, so that the heating mat 4 can be rapidly warmed up. The heating instruction in this embodiment may be input by a user, or may be automatically generated by the system, for example, the heating instruction may be generated at regular time or automatically generated by detecting an environmental parameter (e.g., temperature) and when a heating condition is satisfied, which is not described in detail in this application for the prior art.
Further, referring to fig. 2, the apparatus further includes a temperature detector 6 whose output end is connected to the input end of the controller 3;

The heating-off command may be input by a user, or may be automatically generated according to a preset condition, and is not particularly limited.
In addition, the controller 3 may be further configured to correspondingly control the switch module 5 to turn off the circuit between the energy storage 2 and the heating mat 4 and turn on the circuit between the vehicle-mounted power supply 1 and the heating mat 4 after the energy storage 2 is completely discharged, so as to control the vehicle-mounted power supply 1 to heat the heating mat 4.
Specifically, the controller 3 in this embodiment may further control the switch module 5 to enable the vehicle-mounted power supply 1 to continue to heat the heating mat 4 after the energy storage 1 finishes discharging, that is, after the energy is released, because the temperature of the heating mat 4 in the discharging process of the energy storage 1 is rapidly raised, if the electric quantity of the energy storage 1 finishes releasing, the heating mat 4 is already heated, at this time, the switch module 5 may be controlled to disconnect the circuit between the energy storage 1 and the heating mat 4, and turn on the circuit between the vehicle-mounted power supply 1 and the heating mat 4, so that the vehicle-mounted power supply 1 supplies power to the heating mat 4, and thus the heating mat 4 maintains the current temperature or continues to be heated to the target temperature on the basis of the current temperature.
