The embodiment of the invention discloses a power battery monitoring method. The method comprises the following steps: acquiring state conversion information of an electric vehicle through a battery management system; if the use state is switched to a stop state, converting the voltage of a power battery of the electric vehicle into target voltage through a device with a voltage conversion function; and after the lead-acid storage battery is powered off, using the target voltage to supply power to the battery management system so as to monitor the power battery in a stop state. The monitoring on the power battery is ensured. The invention further provides a power battery monitoring system and an electric vehicle.
