Calibrating State of charge (SOC), what way does it work? How often do I need to fully charge and discharge to reset SOC?
● The complex SOC algorithm has been developed by GTCAP to give a prediction of the remaining capacity based on many real time measurements inside each of the modules. The accuracy of the SOC is very good but its linearity benefits from regular full charge (100% SOC) & cell balancing, and also from periodic discharge below approx. 20% where a re-calibration is performed on each module.
● Generally in vehicle applications we advise the period of this re-calibration can be determined during initial trials so that it can be incorporated within a timeframe alongside other service intervals.
● At low consumption it is important to note that the SOC of the battery can drift – a regular full charge of the batteries does help limit the drift.
