Abstract: In order to solve the problem of high energy consumption of single electric heating system of fuel cell bus and reduce heat loss, an integrated intelligent comprehensive heat management control strategy for the whole vehicle is proposed based on the traditional distributed heat control strategy of fuel cell engine of hydrogen fuel bus. The heat generated by the fuel cell engine during operation is recycled, and the heat is fully converted by plate-fin heat exchanger and used for heating in passenger cabin and defrosting and defogging of front windshield. Realize high integration and fine thermal management. This technology can reduce the energy consumption of a single electric heating system, improve the heating comfort experience of the whole vehicle and greatly improve the economic performance of the whole vehicle.

Key words: hydrogen energy; fuel cell; integrated thermal management; reduce energy consumption
