Chevy Bolt EV's battery shows big improvements over Spark's

Plug-in vehicle battery technology moves fast, and all you need to do to see this in action is to take a look at the new 60-kWh lithium-ion pack inside the 2017 Chevy Bolt EV. Well, you need to do that and then compare it to the battery packs inside of GM's other plug-in vehicles. And you don't even to go as far back as the EV1 to see progress. Let's start with what we know about the new Bolt's pack. It is supposed to drive the Bolt EV over 200 miles on a full charge. It weighs 960 pounds and is made up of 288 cells. Chevy's other all-electric car, the limited-availability Spark EV, had a 19-kWh pack and offered 82 miles of range. It had 192 cells and weighed 474 pounds. So, in the few years since the Spark EV was released, GM engineers have figured out how to get three times the energy capacity and almost two-and-a-half times more range out of a pack that weighs only about twice as much. And that doesn't even get to the price drops. GM has figured out how to get 3x the energy capacity and almost 2.5 times more range out of a pack that weighs only twice as much. Speaking of those 288 cells, that number might sound familiar to regular readers because that's exactly how many are in the new Chevy Volt. But the packs in the Volt and the Bolt are entirely different beasts. For one thing, while the Volt cells are made by LG Chem in Holland, MI, LG Chem will make the Bolt's cells in South Korea. The cell chemistries are also different. We spoke with GM engineer Tim Grewe (again) and while he declined to answer some of our Bolt battery pack questions until more details are unveiled at the SAE World Congress in April, he was able to explain a few things. "The cell inside the Chevy Bolt EV was specifically designed for EV range so it's up on energy," he said. "That's a different cell chemistry than on the extended range Chevy Volt, which is a smaller pack, smaller energy but more power per cell. We work with all of those vehicle requirements and customer demands and we say how do we meet this and we change the chemistry to make it all work." Comparing the 60 kWh in the Bolt and the 18.4-kWh pack in the Volt is really one of those apples to oranges issues, he said. "If you look at the Volt battery pack, how it went from where it was and where it's up to, from 38 miles to 50 miles, that was basic, overall industry improvement. Now, the 18 [kWh] to the 60 [kWh] is extended range vs. EV.

GM promises to add 20 EVs and fuel-cell cars to lineup, paid for by SUVs

DETROIT — General Motors outlined plans on Monday to add 20 new battery electric and fuel-cell vehicles to its global product lineup by 2023, financed by robust profits from sales of gasoline-fueled trucks and sport utility vehicles in the United States and China. "General Motors believes in an all-electric future," GM global product development chief Mark Reuss said on Monday during a briefing at the company's suburban Detroit technical center. Future generations of GM electric vehicles "will be profitable," Reuss said, but added it was not clear when GM could make all its new vehicle offerings zero-emission electric cars. Regulators in China and some European countries have floated proposals to ban internal combustion engines by 2030 or 2040. "We will continue to make sure our internal combustion engines will get more and more efficient," Reuss said. GM shares were up more than 4 percent in midday New York trading on positive comments from Rod Lache, auto analyst at Deutsche Bank. Automakers, including electric vehicle market leader Tesla, lose money on electric cars because battery costs are still higher than comparable internal combustion engines. The company offered sneak peeks of three EV prototypes: a Buick SUV, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM funds its forays into new technology using a river of cash generated by old-technology vehicles popular with its core customer base in the United States heartland. In comparison, Tesla has burned through an estimated $10 billion in cash and has yet to show a full year profit. GM earned more than 90 percent of its $12.5 billion in pretax profits last year in North America, amid robust demand for its lineup of large sport utility vehicles and pickup trucks. The company's profitable operations in China rely on consumer demand for an expanding lineup of gasoline powered SUVs. GM has previously announced plans to make some of its future electric vehicles capable of driving themselves in robot taxi fleets. The company offered sneak peeks of three electric vehicle prototypes: a Buick brand sport utility vehicle, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM collaborated with Korean battery maker LG Chem to build the Bolt battery system. Company officials did not say what companies would supply batteries for the larger fleet of vehicles promised by 2023. Fuel-cell vehicles will also play a role in GM's future, the company said.

Recharge Wrap-up: Chevy bi-fuel Silverado 3500HD Chassis Cab, VW Car-Net works with Apple Watch

Volkswagen's Car-Net app will be compatible with the Apple Watch. Using the app, owners will be able to lock and unlock their car, check charging status or fuel level, locate their car, flash the lights, and honk the horn of their vehicle remotely from their wrist. E-Golf owners can begin or end charging or operate climate control through their Apple Watch. The app can also monitor other household drivers with speed and boundary alerts - perfect for the parent who lends their car to a teenager. Read more in the press release from Volkswagen. Chevrolet is launching the bi-fuel 2016 Silverado 3500HD Chassis Cab. The work truck will now offer a version that will run on both gasoline and compressed natural gas (CNG). "CNG burns cleaner and costs less at the pump than gasoline, making it an appealing option for fleets," says GM's Ed Peper. Companies like Southern California Gas Co. find that trucks like this meet their work needs and help them achieve their goals of greening up their fleets, GM says.

Clean Energy Fuels, co-founded by T. Boone Pickens, will provide UPS with its Redeem brand natural gas, which uses methane captured from landfills. UPS hopes to log 1 billion miles with its alternative fuel and advanced technology fleet by 2020. "Our rolling laboratory approach provides a unique opportunity for UPS to test different fuels and technologies," says Mitch Nichols of UPS. "Today's RNG agreement will help mature the market for this promising alternative fuel." Read more in the press release below. UPS BECOMES NATION'S LARGEST USER OF RENEWABLE NATURAL GAS IN SHIPPING INDUSTRY New Agreement with Clean Energy Will Help Grow Market for Use of Methane Gas from Landfills as Fuel Atlanta, May 5, 2015 – UPS® (NYSE:UPS) today announced it has entered into an agreement to purchase renewable natural gas (RNG) for its delivery vehicle fleet from Clean Energy Fuels Corp. (NASDAQ: CLNE). The deal signifies UPS's plan to significantly expand its use of renewable natural gas for its alternative fuel and advanced technology fleet. The company has a goal of driving one billion miles using its alternative fuel and advanced technology fleet by the end of 2017. Clean Energy Fuels, co-founded by T.
