GM's staff researcher John Suh doesn't believe the market is ready for an all-electric vehicle, citing range anxiety and lack of a recharge infrastructure
Until recently it was hard to define what the Chevy Volt really is – a hybrid a-la Toyota Prius, a plug-in hybrid, an electric car… - , since it’s not even built yet!
To help potential customers like myself – I’m currently shopping for a Prius! – understand what the Volt is, GM’s staff researcher John Suh suggested a new acronym: it’s an ERBEV, which stands for an Extended Range Battery Electric Vehicle!
“The Volt is a battery electric vehicle. The engine will turn on to generate electricity and to assist the battery,” said Suh, in a presentation last week at Xerox’s PARC in Palo Alto, Calif.
Why the Chevy is better than a plug-in hybrid
“In an EREV [like the Volt], the components (battery, drivetrain) are sized to run that car for full performance. A plug-in hybrid vehicle is not practically speaking. You could but then you will run the case, where you have 2 fully redundant powertrains which is not practical,” added Suh who’s located at GM’s Advanced Technology Group in Silicon Valley.
Range anxiety is biggest hurdle for an all-electric car
“Each of us experience this [range anxiety] on a daily basis when we’re on a laptop or a cell phone, doing lots of different things, and far away from a power plug… Now you have a vehicle that has 100 miles range, you’re going to feel it [range anxiety].
A gas engine provides that bit of security. It’s just like a spare tire in your car. Most of us will never touch that thing, but you’re so happy to have it when you get a flat because you can get moving.
Once we get the charging infrastructure that’s ubiquitous, we’ll put the engine right out.”
