EV Home Charging Equipment

EV Home Charging Equipment

This is part four of five in a series of blog posts to answer questions that were received via social media. For the next five days I will publish a new blog post every day relating to the following questions: 

  1. How do EV’s and their batteries perform in cold temperatures?

  2. What are the cost differences between driving electric vs. gas, including maintenance and service costs?

  3. What is the current state of charging infrastructure in NL?

  4. What charging equipment do I need to charge at home?

  5. How long do the batteries last before they have to be replaced and at what cost?

Today I will be discussing what, if any, additional equipment will you need at home to charge your EV.

Depending on the electric vehicle you are using and the level of convenience you would like, there are several home charging options. We’ll go through all of them in this post to help clear up any questions. Remember, most EV owners charge up at home most of the time so it is recommended to use a charger with the most convenience.

So the simplest charging equipment that an EV owner could use at home is your standard 120V receptacle. Most people will have either an exterior receptacle close to their drive way or inside their garage. All EVs come with a charge cord to be able to plug into 120 V receptacles.

The downside with this type of charging (called Level 1 charging) is that it can be slow depending on the size of the battery pack you’re trying to charge. Check out this table below to see how long it would take to charge up these EVs using a 120 V charger.

 EV Table

As you can see it can take quite a long time to charge up an EV on 120 V. However, if you car is going to be sitting for more than 10 hours (example overnight) then charging at 120 V should give you enough EV range for your daily driving. If you think you will be doing more than 60 km of driving per day you may wish to charge at 240 V.

Charging at 240 V is like charging on your range or dryer outlet. It offers a lot more power than 120 V allowing you to charge up much faster. The same table above also has the charging times on 240 V for the same EVs.

 Outside Plug

Some vehicles like the Tesla Model S do not need any other special equipment other than the supplied charging cord that comes with the vehicle. This means you can plug directly into a 240 receptacle like the one below.

 Plug example

Other EVs like the Chevy Volt and Nissan Leaf require a 240 V charge station. There are dozens and dozens of companies who sell these types of chargers that can be installed for a relatively low price. Sun Country Highway is perhaps the most popular of these companies. Green Rock E.V.S can supply and install Sun Country Highway chargers to those who would like the convenience of being able to charge quicker.

In terms of cost, if you are going to be getting an electrician to install a new 120 V or 240 v exterior receptacle or one in your garage it can cost anywhere from $250-$600. If you will be installing a 240 V charging station it can range anywhere from $750-$1,250 for the unit and installation.

As an EV owner of almost 2 years, I can tell you another convenience of going with a 240 V charging station that a lot of people don’t think about. Having the charge cord coiled up, ready to go, whenever you want to charge is much preferred rather than having to get your charge cord out of your vehicle, plugging it into a receptacle and then plugging it into your car. It may not seem like a big deal when the weather is nice, but trust me, when it’s cold, or raining, or snowing, or all of the above, you will enjoy not having to fuss around with any cords. Check out how simple it becomes at the end of the video below where I demonstate this at my home. 

Well that’s all you need to know about EV charging equipment for your home. The feeling of being able to charge at home when ever you want and never having to visit a gas station again is awesome and quite gratifying. It’s hard to explain until you live with it for several weeks and you realize “THIS is how it was meant to be!”
