A battery management system according to the present disclosure is for a battery connected in parallel to a smoothing capacitor through a high side power line and a low side power line. The battery management system includes a discharge control switch connected between a first node and a second node of the low side power line, a temperature sensing circuit including a thermistor, wherein a first terminal of the thermistor is connected to the first node, a precharge switch connected to a precharge power line between a second terminal of the thermistor to the second node, and a control unit. The control unit is configured to turn off the discharge control switch and turn on the precharge switch, for precharging of the smoothing capacitor, when the control unit receives a key-on signal.
