Battery storage unit

The BatteryStorage unit stores electrical energy for later use. It maintains an internal state-of-charge and exchanges power with the rest of a process through its energy stream. Positive duty on the energy stream represents charging while negative duty represents power delivery.

The battery can be combined with other power generation units such as FuelCell or GasTurbine to buffer excess electricity or supply power during demand peaks.

BatteryStorage battery = new BatteryStorage("battery", 5.0e5);
FuelCell cell = new FuelCell("cell", fuel, oxidant);

cell.run();
// store half of the produced power for one hour
battery.charge(-cell.getEnergyStream().getDuty() / 2.0, 1.0);
battery.run();
