SUMMARY We evaluate performance of lithium‐ion batteries on the small electric bus, conducting tests of cell and battery pack using discharge/charge machine. We suggest the test item on distinction between good and bad of a battery. In the discharge/charge cycle tests of cell at environmental temperature (25 °C), the relative capacity was 60% at 10,000 cycles. In the discharge capacity test of battery packs on the small electric bus, the relative capacity maintained more than 90% in progress for approximately 900 days. Finally, based on these results, we analyzed about influence factor on a battery discharge capacity.
