Single string current
of battery value is 0 A, and no
battery overtemperature alarm, battery overvoltage alarm, or battery thermal runaway alarm
has been generated.
Context
To identify a faulty battery, you are advised to test the battery internal resistance.
If conditions are met, the iBAT will automatically perform an internal resistance test periodically.
Procedure
Step 1

Criteria for determining that the iBAT detection function is normal:
The voltage displayed on the WebUI is in the range of the measured voltage ± 0.2%.
The temperature displayed on the WebUI is in the range of the measured temperature ±
1°C.
The internal resistance value is displayed for each battery.
