Cobasys Providing NiMH Battery Systems for Verizon Hybrid Van Retrofits
23 May 2007
|The Cobasys NiMHax 336-70 Battery System.|
Cobasys is supplying its patented Nickel Metal Hydride (NiMH) NiMHax battery systems to Enova for integration into 13 GMC 2500 service vans being retrofitted with hybrid drives for Verizon. (Earlier post.)
The service van program will make Verizon the first major US company to retrofit vans with hybrid power technology for use in its fleet.
The Verizon vans will be equipped with Enova’s 120kW Post-Transmission Parallel Hybrid Drive System supported with the Cobasys liquid-cooled NiMHax 336-70 (336V, 8.5 Ah, 70kW) 2.8 kWh battery system.
The post-transmission electric drive system is integrated behind the transmission and is designed to be installed as a drop-in, fully integrated turnkey fashion into an OEM production line, or—as in this case—retrofitted.
The NiMHax battery system incorporates Cobasys’ high-power Series 1000 12V battery modules and incorporates all necessary features that enable fully integrated “plug-and-play” capabilities. System features include: integrated battery management system hardware and software, redundant safety controls, packaging, wiring, and thermal management based on newly developed liquid cooling systems for optimized performance in high power Hybrid Electric Vehicle (HEV) application. Fully integrated control algorithms have also been implemented to help optimize the energy management functions and product durability.
Cobasys has recently been awarded a number of contracts for hybrid vehicle programs, including: Saturn Vue, Saturn Aura, Chevrolet Malibu, Lotus Engineering “EVE” and most recently, Armor Holdings military vehicle application. Cobasys is also partnering with A123Systems on the development of li-ion battery packs for plug-in hybrids for GM.
Cobasys is a joint venture between Chevron Technology Ventures LLC, a subsidiary of Chevron Corporation and Energy Conversion Devices, Inc.
