I found this info in an information guide regarding changes to the 2017 BRZ:
Battery condition sensor:
The previous (2016 and older) current sensor always maintained control to keep the battery fully charged. The (2017) battery condition sensor calculates the charge status, level of deterioration and internal resistance of the battery from data such as its voltage, current and temperature, and controls charging so that there is always spare capacity available. This allows the recharging rate to be increased when decelerating, which improves fuel efficiency.
