FLYWHEEL CHARGING MODULE FOR ENERGY STORAGE USED IN ELECTRIC MILITARY VEHICLE POWER SYSTEM HIGH-VOLTAGE PULSED AND MULTI-MODE MOBILITY HYBRID

A bsfractOptimal Energy Systems is currently designing andmanufacturing flywheel-based energy storage systemsthat are being used to provide pulses of energy forcharging high-voltage capacitors in a mobile militarysystem. These systems receive their energy from lowvoltagevehicIe bus power (28 VDC) and provide outputpower at over 10,000 VDC without the need for DC-DCvoltage conversion electronics. This energy conversion isaccomplished through the use of OES-patented ultra-highspeedflywheel power module (FPoM) technology.In this paper, recent test data is presented for aprototype FPoM high-voltage capacitor charging source.Adaptation of the technology to energy storage forconceptual multi-mode mobility functions in a militaryvehicIe design with electric propulsion and advancedelectrical loads is described. Physical system designparameters are summarized for both the prototype FPoMhardware and conceptual hybrid electric vehicleapplication. Transient PSPICE electrical analyses andMSC/Nastran finite element analyses characterizeoperation and response in a conceptual high-rate pulsedpower and multi-mode energy storage environmentinvolving (i) regenerative braking, (ii) power peakleveling, and (iii) high-voltage capacitor charging4 Halama
