The 2015 Chevrolet Spark EV will get a lighter, smaller battery for its second model year, as General Motors consolidates electric battery production at its Brownstown, Mich., assembly plant.
The 2015 Spark EV battery will weigh 474 pounds, or 86 pounds less than GM's initial 2014 model. The new battery offers a storage capacity of 19 kilowatts per hour and uses 192 lithium-ion cells supplied by LG Chem. The battery had previously been provided by outside supplier A123 Systems.
