The invention discloses an activation control method and an activation control device of a fuel cell engine. The control method comprises the following steps: acquiring required power of a whole vehicle and required activation power of a fuel cell engine; comparing the activation demand power with the whole vehicle demand power to obtain a comparison result; a control instruction set is generated based on the comparison result, the control instruction set is used for controlling the fuel cell engine to execute a preset activation working condition, and the preset activation working condition comprises that the fuel cell engine performs activation operation at preset power within a preset time period. By the adoption of the activation control method, on the condition that normal driving of a driver is not affected, self-activation mode operation of the fuel cell engine is achieved, the problem that the performance of a fuel cell stack is degraded is solved, and the SOC balance of the vehicle is guaranteed by setting the activation mode working conditions with the purpose of maintaining the SOC balance of the whole vehicle as the target.
Description
technical field [0001] The present invention relates to the technical field of fuel cell vehicles, and in particular, to an activation control method and an activation control device for a fuel cell engine. Background technique [0002] When a fuel cell engine is installed in the vehicle environment, due to frequent changes in vehicle operating conditions, the power of the fuel cell engine changes frequently. Studies have shown that the frequently changing load will lead to the performance degradation of the fuel cell stack. Therefore, it is necessary to regularly conduct steady-state activation operations for fuel cell engines under fixed operating conditions. However, all current fuel cell engine activation schemes are carried on the bench. The fuel cell engine runs with the power demanded by the whole vehicle, and the fuel cell engine is completely controlled by the driver's control will. In this case, the operation of the fuel cell engine is not stable. , there is still...
