The invention discloses a fuel cell system load pulling method based on a whole vehicle energy control strategy. The fuel cell system load pulling method comprises the following steps: S1, counting continuous shutdown placement time of a vehicle-mounted fuel cell system; s2, counting power partitions and proportions of the vehicle-mounted fuel cell system; s3, calculating the power attenuation of the vehicle-mounted fuel cell system; and S4, the VCU analyzes the data obtained in the steps S1 to S3. According to the fuel cell system load pulling method based on the whole vehicle energy control strategy, load pulling, recovery or partial recovery of the performance of the fuel cell system are completed through the real-time data. Statistical analysis is carried out on the continuous shutdown parking time of the fuel cell system, the proportion of each power in the startup operation period and the attenuation condition of each power point through the vehicle control unit, the fuel cell system is parked for a long time or operates at a low power point for a long time, and high-power load pulling is carried out on the fuel cell system through the VCU, so that the performance of the fuel cell system is restored to the optimal state.
