燃料电池客车超低温环境综合智能热管理系统开发

Development of Comprehensive Intelligent Thermal Management System for Fuel Cell Buses in Ultra-low Temperature Environment

提出在-30℃环境下整车一体化热管理系统控制策略,实现燃料电池余热利用,并通过停车启动、启动行驶、稳态供暖三种工况的仿真分析和整车低温环境试验,验证热管理系统和控制策略的节能效果。

The authors propose a control strategy of the vehicle integrated thermal management system in-30℃environment for realizing the utilization of the fuel cell waste heat.Through the simulation analysis on three working conditions of stop-start,start-run,steady-state heating,and the vehicle test of a low-temperature environment,they verify the energy-saving effect of the thermal management system and control strategy.
