The embodiment of the invention discloses an energy management method and device for a low-voltage electrical system of a fuel vehicle. The method comprises the steps that power supply mode information of the fuel vehicle, state of charge (SOC) information of a storage battery, vehicle motion state information and power supply end fault information are obtained; a low-voltage energy control strategy corresponding to the current vehicle is determined according to the power supply mode information, the state of charge SOC information of a storage battery, the vehicle motion state information, the power supply end fault information and a preset vehicle low-voltage energy management strategy, and the preset vehicle low-voltage energy management strategy is a strategy for managing energy of a low-voltage electrical system of a fuel vehicle; the low-voltage energy control strategy comprises at least one of early warning information and load power limiting information. According to the fuel vehicle low-pressure energy management method, the consideration range is more comprehensive, the energy management strategy is more refined, and normal use of the fuel vehicle can be better guaranteed.
