Title:
BATTERY CHARGING PROTECTION CIRCUIT AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/161275
Kind Code:
A1
Abstract:
Disclosed are a battery charging protection circuit and a robot. Input ends of a voltage detection circuit and a voltage comparison circuit are both connected to an output end of a charger. An output end of the voltage detection circuit is connected to an MCU processor. An output end of the voltage comparison circuit is connected to an MOS drive circuit. An MOS module and a current detection module are connected in series between the output end of the charger and a charging input end of a battery pack. The current detection module is connected to the MOS drive circuit by means of a current comparison module. The current detection module is connected to the MCU processor. An output end of the MOS drive circuit is connected to the MOS module. An output end of the MCU processor is further connected to the MOS drive circuit.
