摘要:

提出了基于 2种典型能量管理策略的优化方案, 以研究基于开关模式和基于功率跟随这2种典型能量管理策略对整车热管理系统性能的影响。以燃料电池客车为研究对象,基于Matlab/Simulink软件建立了其热管理系统模型;在基于开关模式和基于功率跟随的行驶循环工况中进行数值模拟。结果表明:在环境温度40 ℃且满载质量13.5 t的工况下,与基于功率跟随的控制策略相比,基于开关模式的控制策略下,燃料电池等热源部件功率变化更平稳;热管理系统的整体最高产热速率下降了33.41%,产热量下降了13.56%。在室温、环境 40 ℃,且不同车辆载质量的极限工况下,基于开关模式控制策略下的热管理系统的产热也下降了10%。

Abstract:

An optimization scheme was proposed based on two typical energy management strategies to investigate the influence of two typical energy management strategies on the performances of vehicle thermal management system. A thermal management system model was established taking fuel cell bus as the research object and based on Matlab/Simulink software. Numerical simulations were carried out in driving cycle conditions based on the thermostat and the power-follower mode control strategy. The results show that the control strategy based on thermostat mode makes the fuel cell power change and other heat source components more stable under the condition of ambient temperature of 40 ℃ and full load of 13.5 t, compared with the control strategy based on power-follower mode. The overall maximum heat production rate of the thermal management system decreased by 33.41%, and the heat production decreased by 13.56%. The heat production of the thermal management system based on the switch-mode control strategy is decreased by 10% under the extreme conditions of room temperature, ambient temperature of 40 ℃, and different vehicle loading masses.

Key words: fuel cell bus, thermal management system, energy management strategy, numerical simulation
