The invention discloses a hybrid power control method and device and a vehicle. In the scheme, consumed power on a high-voltage bus and output power of a fuel cell are obtained firstly, and when the output power of the fuel cell is smaller than the consumed power on the high-voltage bus, namely, the output power of the fuel cell is not enough to supply power to a load, the output power of the fuel cell is controlled to be increased to supply power to the load; with the consideration that the response speed is slow when the output power of the fuel cell changes, the output power of the fuel cell is possibly insufficient to enable the load to work normally in the process, so that the output power of the power cell is controlled to be combined with the fuel cell to supply power to the load, situation that the load cannot work normally due to the fact that the output power of the fuel cell is insufficient to supply power to the load in the process due to the fact that the response speed is low when the output power of the fuel cell changes is avoided, and the reliability in supplying power to the load is improved.
本发明公开了一种混合动力控制方法、装置及车辆,该方案中,先获取高压母线上的消耗功率及燃料电池的输出功率,并在燃料电池的输出功率小于高压母线上的消耗功率时,也即是燃料电池的输出功率不足以为负载供电时,控制燃料电池的输出功率增大以为负载供电,且考虑到燃料电池的输出功率变化时的响应速度较慢,在此过程中燃料电池的输出功率可能不足以使负载正常工作,因此,还控制动力电池输出功率与燃料电池相结合以为负载供电,避免由于燃料电池的输出功率变化时响应速度较慢,从而在此过程中可能会存在燃料电池的输出功率不足以为负载供电进而使负载不能正常工作的情况,提高了为负载供电的可靠性。
