The invention discloses a fuel cell-lithium battery hybrid power system control method and device. The method comprises the steps that the current charge state of a vehicle-mounted lithium battery is obtained; determining a target charge range to which the current charge state belongs from a plurality of preset charge ranges; determining a target gas-electricity power strategy corresponding to the target charge range based on a preset corresponding relation; controlling the gas-electricity power output of the vehicle-mounted fuel cell based on the target gas-electricity power strategy; wherein the preset gas-electric power strategy comprises a preset power output mode, and at least one of preset output power and preset variable load slope; the preset output power and the preset variable load slope are obtained by optimizing the initial output power and the initial variable load slope based on the charge preset condition in the virtual vehicle operation environment. According to the method, the charge fluctuation meeting the charge preset condition can be obtained, and the whole vehicle dynamic property and economical efficiency of the fuel cell vehicle can be improved while the service life of the fuel cell is protected.
