Abstract

The invention relates to a multi-energy-source fuel cell vehicle thermal management system and a control method thereof. The fuel cell vehicle thermal management system comprises a fuel cell subsystem, a storage battery subsystem, a super capacitor subsystem, a heat exchange subsystem and a post-processing subsystem. The control method comprises the steps of detecting the output current and the output power of each energy source, the cooling liquid outlet temperature of each energy source and the heat required by a passenger compartment, and switching the control method of the heat managementsystem among an extremely cold mode, a small cycle, a medium cycle, a large cycle and an extremely hot mode according to the parameters. In each mode, the thermal management system controller realizesthe optimal efficiency of the whole power source part by controlling the flow of the cooling liquid passing through each subsystem, and the quick response of the whole power source part needs to be considered in a low-temperature environment, so that the economy of the fuel cell vehicle and the quick response performance in the low-temperature environment are improved.

Description

technical field [0001] The invention relates to the field of fuel cell vehicles, in particular to a multi-energy source fuel cell vehicle thermal management system and a control method thereof. Background technique [0002] Fuel cell vehicles use fuel cell stacks as the main energy source. Compared with the internal combustion engine system in traditional vehicles and the battery system in pure electric vehicles, they are energy-saving, environmentally friendly, high energy conversion rate, low noise and fast fuel filling, energy High density and other advantages. Among them, the multi-energy source fuel cell vehicle composed of fuel cell, storage battery and super capacitor can combine the characteristics of high energy density, fast dynamic response and high power density of the three to ensure the performance of the whole vehicle. However, for fuel cell vehicles with multiple energy sources, the thermal management system and control method of each energy source part are ...
