 The internal resistance can be measured only when the batteries are fully charged, and no alarm is
generated in the intelligent monitoring system. A measurement can be performed at least 45 minutes
after the previous measurement ends. The battery internal resistance will change to an invalid value
after power-off and then power-on again. By default, the BIM checks the battery internal resistance
once every 24 hours as instructed by the CIM. The red BIM indicator is steady on during the check.
You can also measure the battery internal resistance manually.
 On the home screen of the CIM WebUI, choose Monitoring > CIM System > Running Control,
click Internal resistance, select a battery number, and click Submit to measure the internal
resistance of the battery.
For the diagrams, see the initial configuration parameter manual for the solution in use.
