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.

    本发明公开了一种氢能汽车用低压电源智能保护系统及其控制方法,该低压电源智能保护系统内包含低压蓄电池、低压电源管理继电器、应急启动开关、车辆电控系统、低压供电线束。所述车辆电控系统通过不同的低压电源管理继电器进行供电;检测所述低压蓄电池电量满足预设条件时,控制低压电源保护继电器断开;所述应急启动开关按下后,控制所述低压电源保护继电器闭合以使车辆能正常启动;车辆断电后,所述车辆电控系统的第二控制系统在车辆完成预设功能后,控制延时断电继电器断开。该低压电源智能保护系统能够最大程度降低汽车的静置能耗,进一步延长整车静置停放时间,确保用户用车需求及车辆安全。
