As an EV owner, I have been pleasantly surprised at how well 110 charging has served me so far. My daily routine consists of two simple steps. Plug in when I get home and unplug when I leave.
These simple steps provide almost 100% of the charging I need… BUT…
Sometime you will need to charge at a (public) charging station.
First – Know your standard!
This is an image from a Nissan Leaf. The plug on the left is a CHAdeMO. The plug on the right is the J1772. I don’t believe all Nissan Leaf’s have both plugs. The fast charging CHAdeMO may be optional.
Note: In the United States, your standard home outlets are 110 volt. You may also have one or more high voltage outlets, for example a NEMA 14-50, for an electric clothes dryer.
Most EV’s in the U.S. are going to use the J1772 plug for both 110 volt (3.3 kW) and 240 volt (6.6 kW) charging. Some may have what is referred to has High Power, SuperCharger Stations or CHAdeMO that may support up to 480 volts! Charging from a 110 outlet can be slow, 3-4 miles of charge for 1 hour of charging. This means that an overnight charge may only add about 40-45 miles. Charging from a 240 volt is much quicker. At roughly 15 miles per hour of charge, you can add that same 40-45 miles in about three hours.
Note: Tesla’s have their own Network / Plug / Standard! Tesla SuperCharger
Second – Learn about charging times!
While this topic can be a bit confusing, I am attempting to clear things up a bit here: Miles Per Hour Charge
So, how do I get 240 volt charging at home?
- PlugInCars – Guide to Buying First Home EV Charger
- My recommendation for installing a home 240 volt charger is simple:
- Do not get a hard wired unit. Have an electrician install (2) NEMA 14-50 50-amp outlets in your (2+ car) garage, one on the left side wall (looking in from outside) and one on the back wall. You may need a permit !!!
- Buy a wall mounted charger (EVSA) with a NEMA 14-50 plug rated at 30 Amps or more.
- Here is a selection of companies that make EVSA’s
