Bursting Tesla's charging station bubble
In signature fashion, Tesla Motors unveiled a huge, ambitious plan to build charging stations all over the country so that someone with a Model S could travel from one end of the country to the other without any road trip range anxiety whatsoever.
It was huge, it was grandiose, it was so.. Musk-ey.
Not that there's anything wrong with that. Musk is a huge figure, figuratively speaking, and has done some really awesome stuff that seems to have been pulled off purely by force of personality and determination. PayPal, the banking site that wasn't really a bank, Space X, the civilian space faring company that actually flies, and Tesla, the high-priced electric carmaker that somehow sells the cars it makes.. The guy is really good at pulling off the things other people laugh at.
Still, he's also a master of selling ideas. His presentation to the world to introduce the big, bold new charging station plans was big. Huge, even. It was star-studded, full of glam, and very entertaining. Yet it missed one very important point. One that most people who aren't electric vehicle geeks wouldn't have understood if it had been included, actually.
It's a little pesky thing called plug-in standards. You see, the world has pretty much chosen to use the SAE J1772 plug standard. At least, in regular, everyday, slow-to-charge cars they have. You cannot use the same plug that charges your Volt, Karma, or Leaf with a Tesla Roadster or Model S. They aren't the same and they use different connections. Tesla has a converter for use at public charging stations that allows their cars to work with a J1772 plug-in, but it only works at lower charge speeds and cars that use this plug as standard cannot use the new Tesla Charging Stations.
Funny thing is, Tesla isn't the only one using their own, proprietary standard. Another, competing fast-charging standard is CHAdeMO, for which there are already over 113 stations in the U.S. alone (1,200 more in Japan). Right now, there are actually more EVs on the road worldwide using the CHAdeMO standard than there are using the SAE J1772 standard, which has more than there are using the proprietary Tesla standard.
