General Motors announced that for its 2015 Chevrolet Spark electric vehicle the battery assembly would move to its Brownstown Battery Assembly Plant, with the facility assembling all further batteries for the automaker’s electric cars from now on.
For the 2014 model year of the Spark electric car – an unnamed supplier took care of the assembly work needed for the battery packs, while LG Chem in Holland supplies General Motors for the necessary lithium-ion cells.
For the 2015 model year, GM refreshed the battery pack’s design, reducing its weight by 86 pounds (39 kg), while the Environmental Protection Agency rating of 82 miles (130 km) for the range is unchanged.
“Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range,” Larry Nitz, executive director of GM global transmission and electrification engineering, said in a statement. “Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale.”
The small EV is only sold in the US states of California and Oregon, while the Brownstown plant belongs to a GM subsidiary – GM Subsystems Manufacturing LLC. Last month, the plant got a fresh $65 million investment to further explore and expand the battery systems and the company’s know-how in the area. The plant is also responsible for assembling the battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR plug-in electric hybrids.
