1, J3A is the 7.2V battery pack charging and discharging interface
2, DIS_CHG and PWM control battery pack charge and discharge
3. BV1 and BV2 are respectively connected to the ATmega16 pin, and BV10 and BV20 are used to detect the voltage across the resistor R13.
4. By measuring the voltage drop across R13, the MCU calculates the charging current, and determines the charging and discharging operation according to the current.
problem:
1, LM358 should be used as an intermediate device, the purpose is to convert the voltage value that can not be used by the microcontroller to be usable, right?
2. Ask friends to explain how the microcontroller handles the voltage across R13 and convert it into current
