A slow charge is better than no charge, but the state of California and some of its largest cities don't seem to understand that concept. That's the crux of an argument from Plugs and Cars' Marc Geller (a former contributor to AutoblogGreen), who cites the case of a Nissan Leaf-owning San Francisco police officer who had charging privileges at a Level 1 (i.e., a standard 120-volt) outlet at an employee-only lot taken away, all in the name of public policy.
One Illinois-based company is taking the "slow and steady wins the race" approach to public plug-in vehicle chargers. Telefonix, which has specialized in making retractable cord reels largely used in the aviation industry, is looking to drum up interest in its L1 Power Post, which is what the company says will be the first Level 1 charging station designed for public use, according to Plug In Cars.
Sometime during the first quarter of 2012, SAE International says it will officially establish a worldwide standard, calling for an integrated coupler for plug-in vehicles. The SAE says this J1772 combo coupler will allow plug-in vehicles to be charged from either a conventional, 15-amp AC wall outlet or a DC connection of up to 90 kilowatts.
