Abstract
Embodiments of the present disclosure provide a battery protection board, a battery and a mobile terminal. A battery protection board includes a protection circuit and a detection circuit. The protection circuit is configured to be coupled to a charge and discharge circuit of a battery in a mobile terminal. The detection circuit is coupled to at least part of the protection circuit and configured to detect a voltage drop generated by an impedance of the at least part of the protection circuit and to determine a charging current or a discharging current of the charge and discharge circuit according to the voltage drop and the impedance of the at least part of the protection circuit during a charge and discharge process of the battery.
