Problems solved by technology

[0004] The previous fuel cell engine controllers only completed the basic functions of fuel cell stack power generation, and did not consider the real-time control, safety, and operability of the control very well, and displayed and recorded real-time or historical data The functions are not very convenient. Since the engine is mainly used in automobiles, few of them realize the black box function of the fuel cell vehicle. After the accident or failure of the automobile, the required data can be extracted through the appropriate interface.

Abstract

This invention relates to a car fuel battery motor control method and device, which comprises the following: fuel battery motor controller, air supply system, hydrogen supply system, cooling water recycling system, communication monitor system, fault test alarming and single battery test system. Wherein the controller controls the hydrogen supply system and adjusts the hydrogen flow and pressure according to the orders from CAN bus and current working status and adjusts air supply system and air flow and pressure and timely exchanges the data to judge the current working status is normal.

Description

technical field [0001] The invention mainly relates to a control method and device for a fuel cell engine used in electric vehicles, in particular to a control method and device for a proton exchange membrane vehicle fuel cell engine. Background technique [0002] Fuel cell is a device that converts the chemical energy of fuel into electrical energy. Proton exchange membrane fuel cell (PEMFC) is the fourth generation power generation technology after thermal power, hydropower and nuclear power. In addition to some technical breakthroughs such as battery membranes and catalysts, a good control system and control method are also needed to maximize the potential of fuel cell power generation performance. In addition to being able to work in accordance with the fuel cell workflow, the current fuel cell electric vehicle engine controller also needs to provide corresponding data to facilitate researchers to find out the best control strategy and control meth...
