Last week Panasonic announced that it signed a deal with Ford to provide lithium-ion cells for it's vehicles. Terms of the deal specify that Panasonic will supply battery cells for the Ford Fusion Hybrid and Ford Fusion Energi, as well as the Ford Cmax Hybrid and Ford Cmax Energi. Panasonic will supply the lithium-ion battery cells and Panasonic will assemble them in-house.
Ford is switching from the planned nickel metal hydride batteries to the lithium-ion technology. The lithium-ion batteries will improve Ford's electric vehicles, providing more stored power in the same area, and weighing less than the nickel metal hydride batteries.
The lithium-ion packs will provide 35kW of power, compared to the 25kW from the older Fusion Hybrid NiMH pack. The lithium-ion batteries are lighter and boost specific power to 0.84kW/kg, compared to the 0.412kW/kg of the old NiMH battery packs.
Panasonic has supplied nickel-based battery systems for the Ford Escape Hybrid since 2004.
