The invention discloses a low-voltage power supply intelligent protection system for a hydrogen energy vehicle and a control method of the low-voltage power supply intelligent protection system. The low-voltage power supply intelligent protection system comprises a low-voltage storage battery, a low-voltage power supply management relay, an emergency starting switch, a vehicle electric control system and a low-voltage power supply wire harness. The vehicle electric control system is powered by different low-voltage power management relays; when it is detected that the electric quantity of the low-voltage storage battery meets a preset condition, a low-voltage power protection relay is controlled to be disconnected; after the emergency starting switch is pressed down, the low-voltage power supply protection relay is controlled to be closed, so that the vehicle can be normally started; and after the vehicle is powered off, a second control system of the vehicle electric control system controls the delay power-off relay to be switched off after the vehicle completes a preset function. According to the low-voltage power supply intelligent protection system, the standing energy consumption of the automobile can be reduced to the maximum extent, the standing parking time of the whole automobile is further prolonged, and the automobile using requirement of a user and the automobile safety are ensured.
