1. A method of operating a Multiple Output Dynamically Adjustable Capacity System (MODACS), comprising:
applying a voltage to a load and to an equivalent circuit model of a cell of the MODACS, the equivalent circuit model being electrically parallel to the load, wherein applying the voltage to the load generates heat at the equivalent circuit model, thereby affecting a temperature of the equivalent circuit model;
measuring a parameter of the equivalent circuit model in response to the heat generated by the load;
comparing the parameter of the equivalent circuit model to an ideal model of the cell to determine a state of health of the cell; and
controlling an operating parameter of the cell based on the state of heath of the cell to meet a power requirement for the cell.
