We proposed accelerated life estimation test methods for high-power lithium-ion batteries used in electrical vehicle. The effects of temperature and state of charge on the degradation of full-scale prototype cells (>5 Ah) were investigated from the viewpoints of capacity performance and output performance by carrying out storage tests over more than 100 days. The most appropriate charging method during storage was also investigated.
