    • Disclosed is a mobile terminal incorporating a battery pack utilized as power supply. The mobile terminal includes a positive terminal connected to a battery pack positive electrode, a negative terminal connected to a battery pack negative electrode, a data communication terminal communicating with a circuit in the battery pack, a charge control unit controlling charging of the battery pack via the positive terminal, and a reference voltage output unit outputting reference voltage. The terminal further includes a dividing resistor and a thermistor connected in series between the reference voltage output unit and the negative terminal, a temperature detector detecting temperature, and stopping charging of the battery pack based on the detected temperature, and a switching device controlling the voltage at the predetermined portion. The terminal still further includes a control unit communicating with the circuit in the battery pack via the data communication terminal, and changing the voltage at the predetermined portion when notified abnormality from the battery pack.
