Abstract:
A charging control method and apparatus are provided. The electronic device can include a first circuit board, a second circuit board, and a charge pump chipset. The second circuit board is provided on the first circuit board. The charge pump chipset includes at least two charge pump chips on the first circuit board and at least two charge pump chips on the second circuit board connected in parallel. One charge pump chip on the first circuit board and at least one charge pump chip on the second circuit board are controlled to be in a working state at the same time. In response to a temperature of the charge pump chip in the working state on the first circuit board being higher than a threshold, any charge pump chip on the first circuit board with the temperature lower than the threshold is switched to the working state.
