摘要
针对当前燃料电池汽车热管理各系统独立且分散,没有进行有效统一集成化管理且整车热管理温控差等问题,以提升整车热管理性能为目的,提出了将乘员舱热管理、氢燃料电池热管理和动力电池包热管理集成为整车热管理系统的方案,并设计了氢燃料电池温度+动力电池SOC反馈的自适应等效耗氢最小控制策略。通过仿真分析得到:集成式热管理系统能保障整车在高低温环境下的制冷制热需求,同时基于燃料电池温度+动力电池包SOC反馈等效因子自适应控制策略相比传统控制策略更具有温控能力。
In view of the current problems such as independent and dispersed thermal management systems of fuel cell vehicles,lack of effectively unified and integrated management,and poor temperature control of vehicle thermal management,a scheme was proposed to integrate passenger cabin thermal management,hydrogen fuel cell thermal management and power battery pack thermal management into vehicle thermal management system for the purpose of improving the rationality of vehicle heat pipes.The adaptive equivalent hydrogen consumption minimum control strategy of hydrogen fuel cell temperature+SOC feedback of power battery is designed.The simulation analysis shows that the integrated thermal management system can ensure the cooling and heating requirements of the vehicle in high and low temperature environment,and the adaptive control strategy based on fuel cell temperature+power battery pack SOC feedback equivalent factor has more temperature control capability than the traditional control strategy.
