Recently GM revealed the production charging equipment that will come with the Volt when it can finally be bought.
There will be a portable 120 V unit (R) that can be plugged into any standard receptacle. It will be able to recharge the car fully in 6 hours at 12 amps or 8 hours at 8 amps.
The other device option (L) is a 240 V stationary wall-mounted unit that has to be installed in the owners garage per code. This unit running at 16 amps can recharge the Volt in 3 hours.
Both utilize a newly ratified interface or coupler standard called SAE J1772, that provides durability, communications, and safety functions and well as universal usability among EVs.
The Volt charging units are very robust and designed to withstand even a complete dunk in a bucket of water. As well, there is a flashlight at the tip for finding the receptacle on the car even in the dark.
Furthermore, importantly, the system is designed so the car cannot drive when it is plugged in. The Volt also has a small LED bulb on the top of the dash that flashes when the car is charging so you can tell from a distance.
I actually proposed to GM that they offer a optional charger also capable of 240V 48 amp charging. At that rate, the Volt could be recharged in about 45 minutes. This would be a great feature for those who want it, and would help to encourage infrastructure development as people could recharge their Volts a rest stops in as much time as it takes to have dinner. It would be a great marketing tool as well.
Volt exec Tony Posawatz poured a little water on my enthusiasm.
“Volt battery can/will handle 220V w/48 amps,” he said. “Just not something we are offering from the factory.”
Anyway you too can have a chance to ask questions directly of Gery Kissel, GM’s engineering specialist who developed the Volt’s charging equipment right here below on a live webchat at 2PM EDT:
