A charge wake-up circuit for a battery management system (“BMS”) for an electric vehicle, the circuit including a charging plug connection circuit, a comparator circuit, and a DC wake-up circuit. The charge wake-up circuit monitors the state of the charger after the BMS turns off. If the charger charges the battery pack after the BMS turns off, the BMS will be started by the charge wake-up circuit and continue to monitor the battery pack. If the charger is off-line, the BMS will maintain the low-power state to prevent the automotive lead-acid battery from over-discharging.
