BATTERY CHARGING/DISCHARGING CONTROL SYSTEM AND ELECTRONIC DEVICE

A battery charging/discharging control system and an electronic device, which relate to the technical field of battery charging/discharging. The control system includes: a positive power supply terminal, a negative power supply terminal, a positive battery terminal, a negative battery terminal, a charging/discharging circuit, and a controllable switching circuit. The charging/discharging circuit includes a first sample resistance circuit and a battery protection chip. One end of the first sample resistance circuit is connected to the negative power supply terminal, and there is a first node between the end of the first sample resistance circuit and the negative power supply terminal; and the other end of the first sample resistance circuit is connected to the negative battery terminal. The battery protection chip comprises an overcurrent detection pin, the overcurrent detection pin is connected to the first node.
