Abstract:

Battery degradation is extremely important to EV technologies and is a function of several factors, such as electrode chemistries, operating temperatures, and usage profiles (i.e. vehicle only vs. vehicle-to-grid (V2G) applications). The goal of this research was to assess such impact. Laboratory testing of commercial "18650" Li-ion cells was conducted in Hawaii Natural Energy Institute's Battery Testing Laboratory. The battery test plan used two separate experiments: a cycling experiment to assess the impact of both V2G and grid-to-vehicle (G2V) charging strategies and a calendar aging experiment to assess the impact of temperature and State of Charge (SOC). The results have shown an impact of V2G, temperature and SOC on the battery capacity loss and indicate that V2G use can double the capacity loss when performed twice daily.
