Battery Tech – Not Better Range – Is Why We Should Be Excited about Chevrolet Volt

Chevrolet announced Tuesday that its new 2016 Volt would extend its all-electric range from 38 miles to 53 miles, which is a 40-percent improvement and would satisfy more than 90 percent of normal drives.
The feat itself would put the Volt on par with many all-electric commuters, whose normal range is anywhere from 60 to 90 miles. Of course, the Volt packs with it a 1.5-liter turbocharged four cylinder that bumps that range up to more than 400 miles, but that’s neither here nor there.
Let’s talk about the batteries.

On paper, the Volt’s new battery capacity is 18.4 kWh compared to last generation’s 16.5 kWh — an only 11 percent increase in capacity. Even further, there’s 96 fewer cells in the 2016 Volt compared to the current model and the batteries themselves are 20 pounds lighter.
So where does the 40-percent bump in range come from? Better batteries and a better approach.
Chevrolet has steadily improved its batteries in the Volt since the car came out in 2011 — 16 kWh to 16.5 kWh — but the bump to 18.4 kWh would be the largest improvement in six years to overall storage. Chevrolet has put the car on a diet, too, and that signals a change for the automaker from previous years.
The overall weight of the 2016 Chevrolet Volt is down 250 pounds over the current car (3,543 pounds vs. 3,781 pounds) and 100 pounds of that alone comes from slimmer energy storage.
All the little things — plus big improvements in battery tech — have equaled a 38-percent increase in EV range in six years and the car still costs $33,995, which is only $453 more than the average new car price in the United States. Range wars may become the new horsepower wars.
Almost two years ago, GM announced it was tripling its investment in its battery labs. It appears that investment is starting to pay off.
