Problems solved by technology

[0003] In the existing fuel cell vehicle thermal management system technology, when the vehicle is cold-started at low temperature and heated in winter, there will be excessive energy consumption, and problems such as uneven temperature distribution of the fuel cell and power battery are likely to occur; In the normal working process, the heat release generated by the electrochemical reaction of the fuel cell cannot be well utilized, so that the generated heat is directly dissipated into the air, resulting in waste heat waste, and the energy utilization rate of the vehicle is not high

Abstract

The invention discloses an integrated thermal management system for a fuel cell vehicle. The system combines heat pump air-conditioning technology and can ensure the coordinated work among subsystems of fuel cell thermal management, power battery thermal management, driver's cab thermal management, and motor electrical thermal management. and the coordinated management of the heat of each subsystem. While considering the temperature requirements of the fuel cell and power battery systems, the operating mode of the system is classified according to the temperature requirements of the cab. The invention can effectively utilize the available waste heat, and improve the energy utilization rate of the whole vehicle under the premise of ensuring the reliability and safety of each subsystem, which is of great significance to the application and development of fuel cell vehicles.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to an integrated heat management system for fuel cell vehicles. Background technique [0002] A fuel cell is a power generation device that converts chemical energy into electrical energy. It uses hydrogen as fuel and air / oxygen as oxidant without using fossil fuels. It can continuously and stably output electrical energy and generate water and heat. With the development of fuel cell technology, fuel cell vehicles have also received more and more attention. Fuel cell vehicles can achieve zero pollution and zero emissions, and solve the problems of short mileage of pure electric vehicles. [0003] In the existing fuel cell vehicle thermal management system technology, when the vehicle is cold-started at low temperature and heated in winter, there will be excessive energy consumption, and problems such as uneven temperature distribution of the fuel cell and power battery ar...
