20120319471ENERGY STORAGE SYSTEMS AND METHODS - In an energy storage system that includes a battery and an ultracapacitor, the state of charge (SOC) of the capacitor is the subject of a dynamic set-point.

The control may be based in part upon real-time fast Fourier transform analysis of load current, permitting real-time adjustment of control coefficients. In this way, it is possible to minimize the occurrence of the capacitor being fully charged at a time when it would be desired to be able to absorb high current, for example from regenerative braking. Likewise it is possible to minimize the occurrence of the capacitor being nearly discharged at a time when it would be desirable to have boost power available. A result is that even a relatively small ultracapacitor (having perhaps one two-hundredth the energy storage capacity of the battery) can permit greatly reducing waste heat dissipated in the battery, and can reduce otherwise unnecessary cycling of current into and out of the battery. This can extend battery life and battery performance.12-20-2012

20130147264THREE PHASE INVERTER DRIVER - A system and method of use of a three-phase inverter driver is disclosed. In some exemplary embodiments three single-phase inverters are connected to the three-phase AC input of electric vehicle supply equipment (EVSE) so that each of the single-phase inverters provide one of the three phases of the AC signal used by the EVSE. The single-phase inverters are rectified and either have variance in their output frequencies or have their phases staggered so that the maximum voltage provided to the EVSE remains at a consistently high level. In some cases, the three phases each cross polarity simultaneously, resulting in a drop in the maximum three-phase voltage, so low-capacity capacitors are used in conjunction with the inverters to bridge these gaps in voltage. Embodiments use readily available, inexpensive components that have regulatory safety-approval and therefore may allow implementation on a vehicle or with a load leveling energy storage system.06-13-2013
