The invention provides a fuel cell vehicle energy balance calibration parameter self-adaption method and system, and the method comprises the following steps: enabling a whole vehicle to be in high voltage, and judging the current driving mode of the vehicle, the driving mode including a motion mode, a normal mode and an economic mode; acquiring an auxiliary energy SOC initial value and an auxiliary energy SOH in the current driving mode; performing calibration according to a preset calibration algorithm to obtain a self-adaptive scale factor; and on the basis of the auxiliary energy SOC initial value, the auxiliary energy SOH and the adaptive scale factor in the current driving mode, calculating according to an adaptive rule to obtain an auxiliary energy target SOC set value in the current driving mode. The optimal control target SOC set value can be matched in different driving modes, so that the system has better dynamic property, economical efficiency and reliability. The target control SOC can be adjusted according to the driving mode, and the target control SOC can also be adjusted according to the service life condition of the auxiliary energy system.
