EV_CURRENT_BATTERY_CAPACITY
What it is
Current usable battery capacity for EV or hybrid vehicle
Returns the actual value of battery capacity, if EV or hybrid. This property captures the real-time usable battery capacity taking into account factors such as battery aging and temperature dependency. Therefore, this value might be different from INFO_EV_BATTERY_CAPACITY because INFO_EV_BATTERY_CAPACITY returns the nominal battery capacity from when the vehicle was new.

CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
float value =
mgr.getFloatProperty(VehiclePropertyIds.EV_CURRENT_BATTERY_CAPACITY, 0);This property is read-only — writes are rejected. It fires a callback whenever the value changes.
