Abstract: Energy storage lithium battery cluster is made up by a large number of batteries in series or in parallel. Due to its high voltage, large current and high capacity, the energy storage lithium battery cluster cannot be tested for capacity by EV battery module. This paper introduces the definition of energy storage lithium battery cluster capacity, discusses the influences of the charge-discharge rate, ambient temperature, charging and discharging cut-off voltage on the capacity test of the lithium battery cluster, and compares the test standards for lithium battery capacity. Finally, a novel universal field capacity testing method is proposed for energy storage lithium battery cluster according tothe field capacity testing methods of several manufacturers, which will be helpful for the maintenance of energy storage batteries.

Key words: energy storage lithium battery cluster, capacity test, temperature, charge-discharge rate, charge-discharge cut-off voltage
