摘要

这项研究探索了再利用电动汽车电池的能量储存。在存储规模方面，采用了来自建筑物能源管理系统的18个月的实际负荷概况，以避免一般代表性负荷概况的缺点。在整个项目中，环境温度被用来评估电池的性能。我们的电池退化模型比以前的研究具有更高的r平方，使我们的研究具有独特性。利用非峰期能源套利和太阳能套利分析电池劣化，这两种方法每天使用全周期和半周期，并提供不同的收益率。经济评估使用净现值和内部收益率。研究表明，电价驱动回收期。敏感性分析表明，在10年项目中，非峰期能源套利是不可行的，但电池成本在50 - 60美元/千瓦时，运行温度在35℃以下，将使太阳能套利有利可图。

Energy arbitrage using second-life electric vehicle battery: A feasibility study based on CU-BEMS data

This study explores energy storage from repurposed EV batteries. For storage sizing, 18 months of actual load profiles from a building energy management system are employed to avoid the shortcomings of a general representative load profile. Ambient temperature is used to evaluate battery performance throughout the project. Our battery degradation models have a higher R-squared than previous studies, making our study unique. Battery deterioration is analyzed using off-peak energy arbitrage and solar energy arbitrage, which use full and half cycles per day and offer different yields. Economic evaluation uses net present value and IRR. The study indicated electricity prices drive return period. The sensitivity analysis shows that off-peak energy arbitrage is not practicable for the 10-year project, but a battery cost of $50 to $60 per kWh and operational temperatures below 35 °C would make solar energy arbitrage profitable.
