General Motors Company (GM) shifts Chevy Spark EV battery production in-house

Posted May 14, 2014

General Motors Company (NYSE:GM) is bringing its electric vehicle battery building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its battery assembly plant in Brownstown, Michigan. GM will be shifting production away from A123 Systems and LG Chem will be brought in as a partner instead.

?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.  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,? stated GM’s executive director of transmission and electrification engineering Larry Nitz.

The newly designed battery system will feature an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem?s plant in Holland, Michigan. The battery system weighs 474 lbs. and is 86 lbs. lighter than the system in the 2014 Spark EV.? The improvements will not have an affect on the Spark EV?s MPGe or range rating. The range will remain at an EPA-rated 82 miles and MPGe will remain at 119.

The Spark EV is priced at $19,995 with full federal incentives. It is currently on sale in California and Oregon. The 2015 Spark EV includes Siri Eyes Free, 4G LTE and DC Fast Charging.
