The circuit includes: an internal resistance sensing module, for sensing total internal resistance of serial charge/discharge switch transistors according to a preconfigured ratio in a charging/discharging state; a voltage selection module, connected to the internal resistance sensing module, for switching between different links according to a voltage gating switch so as to be connected to the internal resistance sensing module, to output a charging detection voltage and a charging reference voltage in a charging state, and output a discharging detection voltage and a discharging reference voltage in a discharging state; and an overcurrent signal generation module, connected to the voltage selection module, for switching between different inputs according to an input gating switch so as to generate a charging/discharging overcurrent protection signal according to a comparison result. The present disclosure resolves many problems caused by a precision resistor R in battery protection systems.",
