State of Health

State of Health

SoH (state of health) tracks the history of the battery in the vehicle. Charge/discharge cycles and times are monitored. SoH (state of health) helps the DME determine the proper charging rates and anticipated battery life.
The IBS detects vehicle start based on current draw in excess of 200A. The engine running signal is made available by the DME via the BSD. Internal resistance of the battery is calculated from the current and voltage dip. These indicators are forwarded to the DME. From this data, the DME the state of health (SoH) of the battery.
