I've wired a 220v/240v outlet at home and ready to buy a Level 2 charger.
What the difference between them? There seems to be quite a few options.
I'm planning to mount the charger on the inside wall of my garage and just run the cord under the garage door....maybe get one of those docks to mount to the outside wall. Are only certain J1772 charge plugs weatherproof?
Do I need a fancy WiFi one? What would that do for me other than monitor unwanted charging...Not overly concerned that someone would park in my driveway and use my charger...pretty safe neighborhood.
Are there only one or two Chevy "approved" or does that matter?
All Electrical Vehicle Service Equipment (EVSE), used for Level 1 and Level 2 charging, do pretty much the same thing. The Level 1 EVSE that comes with the Volt is designed for 120VAC and 12 amps maximum. Level 2 charging on the Volt is limited to 240VAC and 15 amps. If you install a higher power rated Level 2 EVSE than one that is specified for 3.6kw, the maximum required by the Volt, the car won't charge any faster; it takes about 4.5 hours @ 240VAC for a full charge. You may want to install a higher power EVSE in anticipation of future charging needs.
You don't need the EVSE to have wi-fi or BT or any other form of internet connectivity. The Volt has OnStar and can signal via SMS text messaging when the Volt is due to be plugged in (according to a schedule you set), when charging has been initiated, completed or interrupted. With OnStar and Voltstats you can access charging data.
The power cord on the EVSE is short, usually about 12", terminating in a molded plug. What type of receptacle did you use when you installed the 240 circuit? The length of the cord from the EVSE to the J1772 plug is about 22 - 25 ft maximum.
The popular brands (at least on the Chevy Volt forum) are Clipper Creek and Juicebox. I believe that Chevrolet uses Siemens EVSE and can arrange for an electrician to install a circuit and the EVSE at your home. You can charge the Volt using any Level 1 or Level 2 EVSE that has the J1772 specification. The Volt does not support DC fast charging, CCS, CHadeMo or the Tesla charging options. The new Chevy Bolt EV supports Level 1, Level 2 (240V, 32 amps for up to 7.7kw) and CCS (Bolt supports 50 to 55kw charging at up to 150 amps. You won't find CCS in many places yet and it is not intended for charging at home.)
The J1772 port was designed for all weather use. Current does not flow through the J1772 connection until the J1772 connector is plugged in and the EVSE and the charger (in the Volt the charger is built into the vehicle) agree on the voltage and maximum amperage for the charging session. The manufacturer will specify if the EVSE is weather proof or needs to be installed indoors such as inside a garage.
