Abstract

The invention relates to a high-voltage charging system, a high-voltage charging battery and a terminal device. The high-voltage charging system comprises the high-voltage charging battery, a controller, a high-voltage charging module and a buck converter, wherein the high-voltage charging battery comprises a plurality of battery cells connected in series; the controller is used for regulating an output voltage of the high-voltage charging module according to a voltage of the high-voltage charging battery; the high-voltage charging module is used for outputting a charging current of a predetermined magnitude to the high-voltage charging battery for charging the high-voltage charging battery; and the buck converter is used for converting the output voltage of the high-voltage charging module or the high-voltage charging battery into a device power supply. According to the technical scheme, a charging voltage can be increased and a charging current can be reduced, so that the energy loss on a charging path is reduced and the heat value is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent terminals, and in particular to a high-voltage charging system, a high-voltage rechargeable battery and terminal equipment. Background technique [0002] With the rapid development of smart devices, the performance of smart devices is getting stronger and stronger, the battery power consumption rate is also significantly faster, and people's demand for fast charging is also becoming stronger and stronger. Current fast charging usually adopts the method of increasing the charging current to increase the charging speed. However, increasing the charging current has relatively high requirements on the charging line and other components on the charging path, which increases the cost of the equipment, the loss on the charging path is relatively high, and the heat generation is also relatively large. Contents of the invention [0003] Embodiments of the present disclosure provide a high-v...
