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.

The real costs of keeping a Chevy Volt on the road

The release of the new, 2016 Chevy Volt is sure to bring a surge of used electric vehicles to the market as early adopters trade their older models in. Many of these cars are selling for a fraction of their original price, thanks in part to federal and state incentives that lowered the initial cost to the first owner, which opens these cars up to a whole new class of consumers. While the prices are getting attractive, potential buyers are still hesitant to buy a used EV due to uncertainty about service and repair costs, but there may be some good news on the horizon. The Chevy Volt comes with a battery warranty that is good for at least 8 years and 100,000 miles, but many of the Volts popping up on the market have passed that 100,000-mile mark. The threat of needing a new battery can be a deterrent, especially with some dealers quoting prices as high as $34,000 for a full "drive motor battery replacement." That sum is more than the MSRP of a 2016 model. Some of the fear of EV maintenance and repair comes from the mystery of the individual pieces that make up the drivetrain and charging system. If we take a look at the Volt in terms of analogs to a traditional internal-combustion vehicle, the outlook becomes a little more friendly. The Volt battery pack consists of three lithium-ion modules in a T-shaped arrangement, each of which can be serviced individually. Module 1 is made up of 90 cells and corresponds to GM part number 22954462, which retails for $3,258.33; module 2 is made up of 72 cells and corresponds to GM part number 22954463, which retails for $2,930.00; lastly, module 3 is made up of 125 cells and corresponds to GM part number 22954464, and retails for $4,933.33. These part numbers have been added to the dealer order systems but have not shown up in the distribution centers at this time. Although all three of the modules add up to a fairly large $11,121.66 total and are still on hold for dealer ordering, the good news is that in most cases these battery cell modules do not need to be replaced. There are many other individual pieces mounted on the battery pack that are serviceable, such as the Battery Energy Control Modules (BECM) and the Battery Interface Control Modules (BICM). These modules control and monitor the battery packs and charging system and have been known to fail while the lithium-ion battery cells are not at fault. Some have been replaced under warranty, but if you are stuck buying one they run about $255 a piece for the part.

Why the Corvette's Performance Data Recorder can be illegal in some states

The Performance Data Recorder with Valet Mode available on the 2015 Chevrolet Corvette Stingray seems like a fantastic tool for many owners. Whether they are taking 720p video while lapping the track in their new 'Vette, or just want to protect their purchase from inconsiderate joyriders, the system offers a lot of functionality in one package. However, one of the PDR's features might get buyers in trouble with the law, and it has nothing to do with recording some illicit high-speed driving on a favorite back road. The problem hinges on the various state laws concerning a person's right to privacy.
According to a letter posted by Jalopnik, Chevy dealers are asking 2015 Corvette owners not to use the Valet Mode portion of the PDR because it records audio in the cabin, in addition to performance specs. That's a problem because privacy laws vary from state to state with some requiring just one side's consent to tape sound and others requiring all parties to agree. According Jalopnik, 15 states mandate everyone's permission beforehand, but it's not clear whether these numbers are up to date. (Actually, the report varies, saying 13 states in some places and 15 in a list.)
According to the letter, Chevy is already working on a software update for the near future to rectify the issue. It's possible that simply adding a warning to drivers and the ability to turn off the audio recording function in Valet Mode might solve the problem. Obviously, this doesn't preclude Corvette drivers from using the performance aspect of the PDR, and owners are free tape lap after lap at the track.
