USE OF ADIPOSE-DERIVED PREADIPOCYTES IN BONE DISORDERS

Not Available Organizations with electric vehicle fleets are faced with a broad range of battery charging requirements. As new vehicles are purchased, additional chargers are needed adding to the cost and complexity of maintenance programs. As electric vehicles become more popular, this problem is becoming increasingly expensive and complex. Creare proposes to develop a standardized charger with the flexibility to rapidly recharge any battery size or chemistry for electric and hybrid vehicles. It is based on a flexible hardware architecture that can automatically be reconfigured for each battery. Very flexible, software based charger configurations are used to connect power electronic building blocks in whatever manner necessary to achieve the voltage, current, and monitoring functions required. Using this method, the same charger can recharge a 24 volt, 200 ampere battery as well as a 600 volt, 20 ampere battery. In Phase I, we will determine Air Force charging requirements, evaluate various power electronic converter topologies, and develop laboratory prototype software and hardware to flexibly recharge batteries of different types. We will evaluate reliability, cost-effectiveness, maintenance, and operating issues in this phase. In Phase II, we will implement the Phase I research by producing field quality chargers to handle the full range of Air Force charging requirements.
