Huawei SmartLi 3.0 - Performing a Capacity Test

Figure 7-5 Starting a shallow discharge test
NO TE
When the battery test is completed normally, the test data is used as common test data.
Record the data obtained from the latest ve tests.
The shallow discharge test automatically stops in any of the following cases:
● The battery discharge capacity reaches the specied value (10%–50%, 20% by default).
● The discharge voltage reaches the warning threshold (calculated in real time).
● The load rate uctuation exceeds 10%.
● A fault alarm is generated.

7.2.2.3 Performing a Capacity Test
Context
This item allows you to fully discharge batteries. A deep discharge test is
conducted to obtain the battery discharge performance data.
NO TICE
Before performing a capacity test, ensure that:
● If the battery has been replaced, choose System Info > Settings > Battery
Settings on the LCD and verify that the value of Installation time has been
changed based on the actual situation.
● The UPS is working in normal mode; oat charging or hibernation has lasted
for 2 hours after the SOC reaches 100%; the load rate uctuation is less than
10%.
● The UPS does not generate any 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.
