Chevrolet Spark EV to Power Up Quickly

Battery system capable of multiple DC Fast Charges daily

SAN FRANCISCO, Calif. – The second entry in Chevrolet’s electric vehicle strategy, the Spark EV, will arrive in California dealer showrooms in summer 2013 with among the best EV range in its class.  The Spark EV’s more than 20 kWh lithium-ion battery pack will continue Chevrolet’s tradition of industry-leading warranty protection of eight years or 100,000 miles.

Spark EV will be the first vehicle on the market to use the recently approved SAE combo charger for DC Fast Charging.  The capability, available shortly after market launch, will enable the Spark EV to recharge up to 80 percent of its capacity in approximately 20 minutes.  The battery system is capable of handling multiple DC Fast Charges daily.  Charging can also be completed in less than seven hours using a dedicated 240V charge.  A 120V charge cord set is standard.  Charging can be managed and monitored remotely using the Spark EV’s smart phone application, provided by OnStar. 

“The Spark EV battery has undergone more than 200,000 hours of testing in our global battery systems labs,” said Larry Nitz, executive director of GM’s global electrification engineering team. “This testing paved the way to allow our customers to do multiple DC Fast Charges daily, to help alleviate range anxiety and improve convenience.”

The battery system, supplied by A123 Systems, has a volume of 133 liters, is comprised of 336 prismatic cells based on A123’s Nanophosphate® lithium iron phosphate chemistry, configured into four modules, weighing a total of 560 lbs.  Like the battery system used in the Chevrolet Volt, the Spark EV’s battery uses an active liquid cooling and heating system, which ensures improved reliability over the life of the vehicle, while providing year-round performance in all climates.  

“A123’s Nanophosphate lithium ion battery technology delivers a unique combination of high power, increased usable energy, long life and excellent safety, which makes it ideally suited for pure electric vehicle applications like the Chevy Spark EV,” said Jason Forcier, vice president of the Automotive Solutions Group at A123 Systems. “ We believe our battery system will contribute substantially to a positive ownership and driving experience of the Spark EV.”

The squared-shaped battery pack is located below the rear seats and directly over the rear axle, in a single, sealed enclosure. The enclosure is constructed from an advanced composite material that improves performance with reduced weight – this is the first production automotive application that uses this high strength material. The battery pack is positioned in the same space used for the fuel tank in internal combustion engine-powered Sparks resulting in minimal body modifications.  Owners will not have to sacrifice when it comes to cabin comfort and cargo space.

Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4 million cars and trucks a year.  Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.
