Battery label is not created as a tracked variable type, so you have to convert it as a tracked variable type (kinetic) and the label dischargeRate is not present on the ACRs.

As Arun said, you have to set it as a kinetic Tracked Variable to be able to set a rate.

You may have a sign error still. If current.dischargeRateLoaded is positive, then you probably want to set the Tracked Variable rate to -1 * current.dischargeRateLoaded . If it is negative, the tracked variable rate is correct but the time calculation to empty needs to be multiplied by -1.
