2015 Chevy Spark will have lighter, smaller battery

As General Motors gets ready to release the 2015 Chevy Spark EV, it is retooling the Brownstown Battery Assembly to build a new battery system for the chirpy little electric car. The new Spark will lose a few pounds and kWh from its lithium-ion pack, but it will keep all of it's performance specs. The current Spark EV uses a 21-kWh lithium-ion battery pack with bits made by A123 Systems (known as B456 Systems during bankruptcy). For the 2015 model, GM is going to build a 19-kWh battery system in-house that will use 192 LG Chem cells. Losing a bit of energy capacity means that the battery system for the 2015 Spark EV will be 86 pounds lighter but it will keep the EPA-rated 82-mile range and 119 MPGe. The 2015 Spark EV also keeps its $26,685 (plus destination) starting price from the 2014 model. The car will once again qualify for a federal tax credit of up to $7,500. LG Chem also supplies the cells for GM's other plug-in vehicles from its facility in Western Michigan. The Brownstown production line currently builds the battery packs for the Chevy Volt, the Opel Ampera and the Cadillac ELR. You can read our first drive of the 2014 Chevy Spark here. Brownstown Battery Assembly Expands Capabilities Will build battery system for 2015 Chevrolet Spark EV 2014-05-14 DETROIT – General Motors will bring all 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, Mich. "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," said Larry Nitz, executive director of GM global transmission and electrification engineering. "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." A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem's plant in Holland, Mich. The battery system weight of 474 lbs. is 86 pounds lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR.

Opel CEO talks new EV, will likely be fresh face for Chevy, too

The rumored demise of the Opel Ampera has been confirmed, but there's good news, too. Opel CEO Karl-Thomas Neumann has been busy Tweeting information about the brand's next plug-in vehicle, admitting that the Ampera is on the way out but that plug-in vehicles are here to stay. His Tweets, in full, read: After the eventual run-out of the current generation Ampera, we'll introduce a successor product in the electric vehicle segment. Our next electric vehicle will be part of our massive product offensive – with 27 new vehicles in the 2014-2018 time frame. We see eMobility as important part of the mobility of tomorrow and we will continue to drive down costs & deliver affordability. As we learned earlier this week, the Ampera will not be refreshed when the current Chevy Volt is updated, most likely because of slow sales. Opel sold just 332 Amperas in the first five months of 2014. For now, General Motors is still building Amperas in Michigan for export to Europe. So, what might this new EV mean for the General Motors plug-in fleet? Official spokespeople are being quiet, but we think it's safe to say the new EV Neumann is talking about is not simply a rebadged Chevy Spark EV. This is the first official word about an entirely new EV, and we expect it will come to both the Chevrolet and Opel brands.
