Description

technical field

[0001] The invention relates to the technical field of automobile heat management, in particular to a fuel cell hybrid electric automobile heat management system, method, vehicle and medium. Background technique

[0002] There are two power sources for fuel cell hybrid vehicles, that is, fuel cell engine and power battery. Because the conversion efficiency of the fuel cell engine is very low in a low temperature environment, it needs to be warmed up. The discharge power of the power battery is also very low in a low temperature environment, especially when the state of charge of the battery is low, the temperature has a great influence on the discharge capacity of the battery. In addition, most fuel cell hybrid vehicles use PTC hot air air conditioners to provide warm air for the driver, which is less economical for heating.

[0003] Therefore, it is urgent to provide a fuel cell hybrid vehicle thermal management system, method, vehicle and medium to solve ...
