The invention relates to a charging control method and device, a charging circuit, electronic equipment and a storage medium. The charging circuit comprises a rectifying circuit, a plurality of receiving coils and a plurality of filter capacitors, wherein the number of the receiving coils and the number of the filter capacitors are both equal to the number of the of battery cells; the plurality ofreceiving coils are connected with the rectifying circuit; the rectifying circuit is connected with a plurality of battery cells, and the plurality of battery cells are connected in series; the plurality of filter capacitors are connected with the plurality of battery cells in parallel one by one; and the rectifying circuit is used for controlling each receiving coil to charge the battery cell ofthe current stage in the first half period of each charging period and controlling each receiving coil to charge the battery cell of the next stage in the second half period of each charging period.According to embodiments of the invention, the battery cell of the next stage is charged in the second half period, so the voltage of the battery cell of the current stage and the voltage of the battery cell of the next stage can be balanced, and the voltages of the two battery cells are kept the same or close, so the situation of large voltage difference of battery cells is avoided, charging timeis shortened, and charging efficiency is improved.
Description
technical field [0001] The present disclosure relates to the technical field of charging, and in particular, to a charging control method and device, a charging circuit, electronic equipment, and a storage medium. Background technique [0002] Currently, electronic devices such as smart phones are provided with a wireless charging circuit, and the wireless charging circuit is a single-module charging circuit. In order to increase the charging power, in the related art, the current-carrying capacity of the circuit device can be increased to increase the charging power, so that the power of the single-module wireless charging circuit may reach a bottleneck. In addition, in order to meet high-power charging, the diameter of the wireless coupling coil must be increased, but the wireless coupling coil will occupy a large space, which is not conducive to the volume and weight of the device. Contents of the invention [0003] The disclosure provides a charging control method and...
