The invention discloses a hydrogen hybrid power locomotive thermal management system and a control method, the hydrogen hybrid power locomotive thermal management system comprises a fuel cell thermal management system, a power battery thermal management system and an intermediate heat exchange device, and the power battery thermal management system comprises a power battery cooling liquid circulation loop. The power battery cooling liquid circulation loop comprises a power battery cooling liquid main loop, a power battery cooling liquid heating branch, a power battery cooling liquid heat exchange branch, a first electronic three-way valve and a second electronic three-way valve, and a first radiator is arranged on the power battery cooling liquid main loop; and the power battery cooling liquid heating branch, the power battery cooling liquid heat exchange branch and the first radiator are connected in parallel. The cooling liquid of the power battery can be heated by using the waste heat of the fuel battery, and when the waste heat is insufficient, the cooling liquid can be heated through the power battery cooling liquid heating branch, so that the influence on the temperature of the fuel battery can be reduced, and the fuel battery is maintained to operate at a normal temperature.

    本发明公开了一种氢混合动力机车热管理系统及控制方法,氢混合动力机车热管理系统包括:燃料电池热管理系统、动力电池热管理系统和中间换热装置,动力电池热管理系统包括动力电池冷却液循环回路,动力电池冷却液循环回路包括动力电池冷却液主回路、动力电池冷却液加热支路、动力电池冷却液换热支路、第一电子三通阀和第二电子三通阀,动力电池冷却液主回路上设有第一散热器,动力电池冷却液加热支路、动力电池冷却液换热支路和第一散热器并联。可以利用燃料电池的余热对动力电池的冷却液进行加热,当余热不足时,可以通过动力电池冷却液加热支路对冷却液进行加热,此时可以减小对燃料电池的温度影响,从而使得燃料电池维持在正常温度运行。
