Choose Plug-in or Hardwire

You can power a residential EV charging station by hardwiring the unit into your home's electrical panel or simply plugging it into a 240V outlet – just like you would for an electric clothing dryer.

Most customers will only need a 32A charging station that can easily be installed and operated through a 240V plug. The plug-in option (with adapters available for many models to fit standard 120V, clothes dryer, or RV-type outlet) is optimum for users who think they will need a portable charger. A certified electrician will need to install a dedicated breaker in your home's electrical panel along with a 240V plug, unless you intend to utilize an adapter (not recommended for requent charging). This option is ideal for people who think they will need a portable charger and can take it to another location.

Alternatively, a certified electrician can hardwire an EV charging station directly into your home's electrical panel. If you have a Tesla Model S or X and want to maximize your charging speed then you will need a 75 Amp charging station which must be hardwired into your electrical panel. 

Get the Power you Need

Most customers will only need a 32 Amp charging station to maximize the charging speed of their electric vehicle. Your electric vehicle will have an onboard charger that will limit the speed in which your car's batteries can be charged. 

However, the Tesla Model X and Model S have dual-onboard chargers which enable the batteries to be charged at a faster rate. These Tesla models can fully utilize a 75 amp charging rate whereas other cars would not charge any faster due to the limits of their onboard charger.

Be sure to check the specifications of your electric vehicle to determine the limits of the onboard charger and the maximum charging speeds.

 

    Make Your Charger Smart

    Many of today's residential EV charging stations come with built-in Wi-Fi connectivity that allows you to monitor your energy use and control the charger's setting remotely. Find out if a connected EV charger is right for you.

    Wi-Fi Connectivity

    Connecting your EV charging station to Wi-Fi can enable you to view real-time electricity use and set charging schedules to ensure your electric vehicle is always charged when you need it. If you are on a Time-of-Use rate plan, the scheduling functionality can also help to lower your bill by charging at the lowest electricity rates.

    Smart Home Connection

    Customers can also connect eligible EV charging stations to their smart home devices such as Amazon Echo or Google Home. With Alexa voice controls or Google Voice Assistant users can start, pause or resume charging with simple voice commands. 

     

     

    Charge Time Table

    This Charge Time Table shows approximately how much electric range a typical EV can recover for charging stations with different capacities. Level 1 charging stations use 120 V, while Level 2 charging stations use 240 V. Charging capacity is rated in kilowatts (kW), while the vehicle's battery pack is rated in kilowatt-hours (kWh).
