Research on the performance of fuel cell vehicle at cold start of -30 ℃

In this paper, collected the operation data of a fuel cell vehicle (FCV) at - 30 ℃ by analyzing the vehicle CAN message. Took stack temperature, stack voltage, stack calorific value and battery SOC as the target objects, analyzed the control logic of fast cold start of the fuel cell vehicle stack at low temperature, and summarized the technical highlights of the fuel cell vehicle, which can be used to guide the product development of domestic automobile enterprises.
