Problems solved by technology

Charging by increasing the voltage, the high voltage will generate more heat, the charger and electronic products will heat up, accelerate the aging of the battery, and cause greater damage to the battery. At the same time, the high temperature of the battery will also bring certain safety hazards; by increasing the current Compared with the high-voltage charging method, it generates less heat, has less damage to the battery, and is relatively safer, so it is used more. However, under the original high voltage, the current cannot be increased too much, and there will be certain degree of fever, there are still potential safety hazards

Abstract

The invention relates to a multi-pole grouping charging module, a charging system and a multi-pole grouping charging system. The multi-pole grouping charging module comprises a rechargeable battery, avoltage dividing chip and a charging interface. The rechargeable battery comprises a plurality of sub-battery modules which are sequentially connected in series, a positive tab is led out from each sub-battery module, a common negative pole is led out from each sub-battery module, a plurality of output interfaces of the voltage division chip are connected with the positive tabs of the sub-batterymodules respectively, and an input interface and the common negative pole of the voltage division chip are led to the charging interface respectively and used for being connected with a power supply.According to the invention, a high voltage output by a power supply is divided into a plurality of low-voltage channels through the voltage division chip, and the low-voltage channels are connected with each sub-battery module for multi-pole grouping charging; under the condition that the voltage is constant, the voltage borne by each sub-battery module is smaller, multi-path simultaneous low-voltage charging is achieved, rapid charging is achieved in the mode of increasing the current, the heating amount is smaller, the durability and safety of the battery are guaranteed, and potential safety hazards in the charging process can be effectively reduced.
