7.3.2.3 Performing a Group Capacity Test

Context
If multiple SmartLi cabinets are connected in parallel, discharge each SmartLi one
by one. (When a SmartLi is fully discharged, charge the SmartLi until its SOC
reaches 100%, and then discharge the next SmartLi until all SmartLi cabinets are
fully discharged.) A deep discharge test is conducted to obtain the battery
discharge performance data.
Before performing a capacity test, ensure that:
● The active power of the UPS is greater than 20 kW.
● (Total power of SmartLi cabinets in the system – Power of a single SmartLi) >
● The UPS is working in normal mode; float charging has lasted for 5 minutes
● The UPS generates no battery overtemperature, overvoltage, or overcurrent
● The mains, batteries, charger, and discharger are normal. No overload alarm is
● The SmartLi generates no alarms related to lithium batteries.

NO TE
The capacity test automatically stops in any of the following cases:
● The minimum cell voltage reaches 2.65 V.
● The load fluctuation exceeds 10%.
● An alarm is generated.
The test is complete when the minimum cell voltage reaches 2.65 V. The test data is
obtained from the capacity test. Save the test data obtained from the latest 36 tests.
