9. A method of managing at least one of charging and discharging of a battery, the method comprising:
receiving, by a controller device, at least one battery state of the battery from at least one sensor;
providing, by the controller device, the at least one battery state as input to a tanks-in-series model that represents the battery; and
controlling, by the controller device, at least one of charging or discharging of the battery by using at least one output of the tanks-in-series model to determine at least one of a current or a voltage for use in the at least one of charging or discharging of the battery;
wherein the tanks-in-series model includes:
a tank model that represents an anode of the battery;
a tank model that represents a separator of the battery; and
a tank model that represents a cathode of the battery.
