1. A power supply control method based on mobile power sources, comprising the following steps:(a) switching on the mobile power sources and enabling the heating circuit to start heating up;
(b) detecting the electric current with an electric current A detection device: if the electric current A is greater than a hibernation electric current A0, enabling the heating circuit to continue heating up; if the electric current A is smaller than the hibernation electric current A0, proceeding to step (c);
(c) keeping the mobile power sources in the activated state by making the single chip microcomputer send a pulse voltage lasting for a time period t2 to the heating circuit every time period t1, and repeating the step (b);
(d) enabling the heating circuit to stop heating when the temperature reaches the preset value and then repeating the step (b).
