Hybrid power pack.Cobasys (Orion, MI) is a joint venture of ChevronTexaco Technology Ventures and Energy Conversion Devices [ECD ECD Early Childhood Development ECD Electron Capture Detector ECD Energy Citations Database ECD Executive Creative Director (advertising) ECD Ethyl Cysteinate Dimer ECD Electron Capture Dissociation ECD Electronic Civil Disobedience ] that arose out of ECD's involvement with GM's EV1 electric car program. Soon, another GM project will put it on the map with OEMs everywhere. Though Cobasys officials refuse to confirm it, GM sources indicate the company's NiMHax HEV HEV abbr. hepatitis E virus HEV hemagglutinating encephalomyelitis virus of pigs. (Nickel Metal Hydride (NiMH) A rechargeable battery technology that has approximately 30-50% more charge per pound than nickel cadmium. Introduced in the early 1990s, it uses nickel and metal hydride plates with potassium hydroxide as the electrolyte. , Hybrid Electric Vehicle A hybrid electric vehicle (HEV) is a vehicle which combines a conventional propulsion system with an on-board rechargeable energy storage system (RESS) to achieve better fuel economy than a conventional vehicle without being hampered by range from a charging unit like an ) battery pack will be used in the strong hybrid version of GM's 2007 full-size SUVs. Liquid-cooled NiMHax HEV battery packs range in capacity from 144 volts/30 kW to 672 volts/280 kW, and all are based on combinations of three basic stand-alone battery pack modules-144 volts/30 kW, 288 volts/60 kW, or 336 volts/70 kW. The packs are fully sealed, have integral thermal management and state-of-charge systems, CAN communication busses, and a built-in high-voltage interlock A device that prohibits an action from taking place. that requires secure electrical connections before the unit can operate. Cobasys says the packs can be distributed around the vehicle, or repackaged without altering the basic components. This speeds design validation, and offers plug-and-play interchangeability. |
