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.
