Cobasys confirmed that it will provide the NiMHax Nickel Metal Hydride (NiMH) battery system for General Motors’ redesigned 2008 Chevrolet Malibu Hybrid Sedan announced at the 2007 North American International Auto Show in Detroit. (Earlier post.)
The Chevrolet Malibu arrives in showrooms in fall 2007 and features the same GM Hybrid Belt Alternator Starter (BAS) system that powers the hybrid Saturn Vue Green Line SUV and 2007 Saturn Aura Green Line mid-size sedan.
The Malibu hybrid combines an electric motor/generator with a 2.4L Ecotec VVT four-cylinder engine, Hydra-Matic 4T45 four-speed transmission and Cobasys 36V NiMH battery pack.
Both Saturn Green Line vehicles and the Malibu hybrid system provide: an electric power assist during acceleration; increased fuel economy through engine shut-off at idle; fuel cut-off during deceleration; and the capability to capture electrical energy through regenerative braking.
Cobasys designed the NiMHax 36-Volt system specifically for GM’s hybrid applications. The NiMHax 36 Volt systems will be manufactured at the Cobasys facility in Springboro, Ohio.
General Motors has awarded an advanced battery contract to Cobasys and its partner A123Systems to design and to test lithium-ion batteries for both plug-in hybrids and the E-Flex series of extended range electric vehicles, of which the Volt is the first prototype.
Cobasys is a joint venture between Chevron Technology Ventures LLC, a subsidiary of Chevron Corporation and Energy Conversion Devices, Inc.
