While General Motors previously outsourced battery production for the 2015 Chevrolet Spark EV to LG, the company is now bringing production in-house to its Brownstown, Michigan battery assembly plant. This facility already produces batteries for the Chevrolet Volt and Cadillac ELR, and will begin making a new battery system for the 2015 Spark EV that’s slightly more efficient than before.
This new 19-kWh lithium-ion battery pack still uses cells produced at LG Chem’s plant in Holland, Michigan, but weighs 86 lbs less than the system previously used in the 2014 Chevrolet Spark EV. Whereas the pack was previously rated at 21 kWh and used 336 cells, it now uses only 192 cells due to improved energy efficiency. The weight loss likely means that the car will be slightly more efficient, but its EPA-rated MPG-e and range numbers will not change as a result of this update. The 2015 Chevrolet Spark will still be rated at an estimated 82 miles of range and 119 MPG-e combined, and the battery still supplies power to the same electric motor that produces 140 hp and 400 lb-ft of torque.
The 2015 Chevrolet Spark EV is already on sale in California and Oregon, and features a few other changes like the addition of available 4G LTE capability. Pricing remains the same as 2014 for the standard 1LT model which carries an MSRP of $27,495 with destination, and government tax incentives are still available for this model.
