The invention discloses an all-in-one charging system for a vehicle-mounted storage battery of a hydrogen fuel cell vehicle. The all-in-one charging system comprises a vehicle control unit, a data monitoring center, a wireless transceiving and detecting system and a charging system. The wireless transceiving and detecting system comprises a vehicle-mounted remote terminal TBOX and a battery management system BMS; the TBOX is in mobile wireless connection with the cloud platform; the BMS has a timed wake-up function and a function of collecting the voltage of a vehicle-mounted storage battery; the charging system comprises a fuel cell system, a fuel cell DC/DC voltage boosting assembly, an all-in-one control system, a vehicle-mounted lithium battery system, a vehicle-mounted low-voltage storage battery system and a DC/DC voltage reducing assembly. The charging method based on the charging system can realize three charging modes, and is used for independently charging the lithium battery system or the low-voltage storage battery system or simultaneously charging the lithium battery system or the low-voltage storage battery system. According to the all-in-one power supply system and method, the power supply circuit is optimized, the energy consumption is reduced, and the power supply efficiency is improved.
