CPC H02J 7/00309 (2020.01) [H02J 7/007192 (2020.01)] | 15 Claims |
1. A charging control method that is applied to an electronic device having a first circuit board, a second circuit board that is provided on the first circuit board, and a charge pump chipset having at least two charge pump chips provided on the first circuit board that are connected in parallel with at least two charge pump chips provided on the second circuit board, the charging control method comprising:
controlling one charge pump chip on the first circuit board and at least one charge pump chip on the second circuit board to simultaneously be in a working state; and
in response to a temperature of the charge pump chip in the working state on the first circuit board being higher than a set threshold, switching any charge pump chip on the first circuit board with a temperature lower than the set threshold to the working state;
wherein controlling one charge pump chip on the first circuit board and at least one charge pump chip on the second circuit board to simultaneously be in the working state comprises:
when the electronic device is in a charge only state, controlling one charge pump chip on the first circuit board and one charge pump chip on the second circuit board to simultaneously be in the working state;
when the electronic device is in a screen-on charging state, controlling the one charge pump chip on the first circuit board to simultaneously be in the working state with the at least two charge pump chips on the second circuit board.
