Battery Health Monitoring

One important feature of a battery management system is to provide the user with the overall health of the battery pack.  The Orion BMS monitors the internal resistance of each cell and tracks the capacity of the weakest cell. It uses this information to calculate a cell health percentage value from 0 to 100%. The BMS then compares the calculated cell health information against preprogrammed thresholds and if any cells (or the entire pack) fall short of the threshold, a trouble code is set and freeze frame data is stored for later analysis.
