Abstract

The invention discloses a thermal management system for a fuel cell vehicle, comprising a hydrogen fuel cell stack, a hydrogen catalytic combustion reactor, an electric heater, a frequency conversion fan, a water supply tank, a frequency conversion water pump, a deionization device, a particle filter, and a bypass valve , temperature sensor and controller. The invention discloses a control method for a thermal management system of a fuel cell vehicle.

Description

technical field [0001] The invention relates to the field of fuel cell vehicles, in particular to a fuel cell vehicle thermal management system and a control method thereof. Background technique [0002] A proton exchange membrane fuel cell is a device that directly converts chemical energy into electrical energy. Because of its high efficiency, zero emissions, low noise and low operating temperature, it is considered to be an ideal substitute for future vehicle power sources, and has attracted the attention of governments around the world. With the advancement of technology, some fuels are currently Battery cars have entered commercial operation. [0003] One of the problems faced by vehicle fuel cells is the start-up in low temperature environment. At present, the heating device of most fuel cell vehicle thermal management systems is electric heating, but in low temperature environment, if the power battery is used as the source of electric heating device , The power bat...
