1. A method of managing power between the multiple components of a hybrid electrical energy storage system (HESS) comprising: providing at least two power storage elements, and at least one renewable power source; and managing at least one of a power and energy distribution among the at least two power storage elements with a fuzzy logic controller using a hardware processor that is configured to increase or decrease current to each of the at least two power storage elements using a fuzzy rule base that is dependent upon at least one of a state of charge for each of the at least two power storage elements, and a requested power demand of the hybrid electrical storage system; wherein the at least two power storage elements comprise an ultracapacitor and a battery; and wherein the fuzzy logic controller employs membership functions to assign values to input variables of positive big, positive small, zero, negative small and negative big for the requested HESS power (P HESS ), state of charge for the battery, and the state of charge for the capacitor, wherein the input variables correspond to output variables for the battery reference current (I bat ) and the deviation from target power (ΔP) from the fuzzy logic controller as set by the fuzzy rule base.
