【Abstract】 A heating schedule of fuel cell vehicles, which was based on heat pumps combined with thermal storage system was proposed to facilitate the pre-heating of fuel cell vehicles and increase the cold-start rates with decreasing the energy consuming of fuel cell vehicles. The dynamic simulation of fuel cell vehicle system was carried out, and the influence of the system with or without heat storage device on the vehicle operation was compared. The results show that in freezing environments, the heat storage unit ensures the continuity of the heat source of the circulating coolant during the driving cycle, and the heat pump and combined heat storage heating solution can reduce the energy consumption of the air conditioning system by 26% compared to the thermal management system without the heat storage unit, indicating that the heating system assisted by the heat storage device can improve the cold start characteristics of fuel cell electric vehicles in winter and optimize the thermal management of the vehicle battery system.
