Huawei SmartLi 3.0 - Performing a Group Capacity Test

7.2.1.3 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.
NO TICE
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) >
UPS active power x 110%.
● The UPS is working in normal mode; oat charging has lasted for 5 minutes
after the SOC of batteries reaches 100%; the load uctuation of the system is
less than 20%.
● The UPS generates no battery overtemperature, overvoltage, or overcurrent
alarm. No generator is connected to the UPS.
● The mains, batteries, charger, and discharger are normal. No overload alarm is
generated.
● The SmartLi generates no alarms related to lithium batteries.
