提出了一种与电动汽车充电站集成的固体氧化物燃料电池(SOFC)热电联产系统。为了验证该系统的可行性，作者对该系统的运行模式进行了数值模拟，使用2003年5月至2004年4月在一个多户公寓中测量的电力和热力需求。根据模拟结果，计算了系统的总体效率和一次节能率。对于多户公寓中安装的拟议系统，还对电动汽车充电的可用电能进行了评估。结果表明，年平均总效率达到77%左右(LHV)，全年预期一次节能率超过30%。此外，还发现所提出的系统可以为电动汽车充电提供足够的电能。因此，可以得出结论，所提出的SOFC系统可以成功地将电/热能联产和电动汽车充电结合在一起，同时保持较高的能源效率和与能源消费模式的良好匹配。
The authors propose a solid oxide fuel cell (SOFC) co-generation system integrated with an electric vehicle (EV) charging station. To examine the feasibility of the proposed system, the authors numerically simulated the operation pattern of the proposed system, using the electric and thermal demands measured at a multifamily apartment from May 2003 to April 2004. Based on the simulation results, the authors calculated the overall efficiency of the system as well as the primary energy saving rate. The available electric energy for EV charging was also evaluated for the case of the proposed system installed in the multifamily apartment. As a result, it is made clear that the annually averaged overall efficiency reaches about 77% (LHV) and the expected primary energy saving rate exceeds 30% throughout the year. In addition, it is also found that sufficient amount of electric energy for EV charging can be obtained from the proposed system. Therefore, it can be concluded that the proposed SOFC system can successfully combine electrical/thermal energy co-generation and electric vehicle charging while maintaining high energy efficiency and good matching to energy consumption patterns.
