and step 400, after the power battery is charged, controlling a vehicle-mounted charger to heat the power battery according to the heating power.
It should be noted that, in the embodiment of the present invention, by acquiring the heat preservation setting information sent by the mobile terminal, after the charging of the vehicle is finished, the vehicle is autonomously subjected to heat preservation heating according to the heat preservation setting information, so as to avoid the problem that the automatic heat preservation time is not long enough or the power battery cannot be autonomously set to preserve heat after the low-temperature charging in the prior art is finished.
Specifically, before step 100 is executed, the method further includes:
and acquiring vehicle charging information before acquiring the heat preservation setting information sent by the mobile terminal.
It should be noted that, specifically, the vehicle charging information sent by the mobile terminal may be acquired through an in-vehicle communication module, and the in-vehicle communication module may specifically be a TBOX of the vehicle. In addition, the method can also comprise the following steps: receiving a charging setting instruction sent by the mobile terminal, and feeding back the charging setting instruction to the mobile terminal after the charging setting instruction is successfully received; the mobile terminal is, for example, a driver's smartphone, a tablet computer, or other device capable of performing wireless communication.
Further, after step 100, the method further includes:

and feeding back the information of the electric quantity consumed by the estimated heat preservation time and/or the estimated mileage after heat preservation to the mobile terminal.
For example, the following are: after the charging time and the vehicle using time are successfully set by the smart phone, setting the heat preservation preheating starting time and the heat preservation finishing time of the heat preservation setting information; after the heat preservation setting information sent by the mobile terminal is obtained, calculating the information of electric quantity consumed by the predicted heat preservation time or the mileage after heat preservation prediction in the vehicle, and feeding the information back to the mobile terminal; for example, the feedback information predicts that the heat preservation duration consumes electric quantity information beyond the expected use effect, the stop or the shortening of the heat preservation duration can be set, new heat preservation setting information can be obtained again in the vehicle, and naturally, feedback information in the word of "successful setting" can be fed back to the mobile terminal after the command setting is successfully obtained each time.
Further, after feeding back the information of the consumed electric quantity of the estimated heat preservation time and the estimated mileage after heat preservation to the mobile terminal, the method further comprises the following steps:
acquiring heat preservation setting information sent again by the mobile terminal;
and according to the re-sent heat preservation setting information, re-determining the heat preservation preheating starting time and the heat preservation ending time for preserving the heat of the power battery after the charging is finished.
Specifically, if the heat preservation setting information sent again by the mobile terminal is not obtained within the preset time, step 200 is executed, and the heat preservation preheating starting time and the heat preservation ending time for heat preservation of the power battery after charging are determined according to the heat preservation setting information.

Specifically, the step 400 includes:
after the power battery is charged, when the timing module in the vehicle starts to time, controlling the vehicle-mounted charger to heat the power battery by using the heating power;
