How to choose Electric Vehicle Supply Equipment (EVSE)

Why don’t EVs simply have a retractable cord that enables the driver to charge from any 120v outlet?
 
While some vehicles do offer the option, or the ability, to connect to a 120V outlet; in general, this method of charging is not terribly efficient and usually only allows the user to charge at a rate of about 6.4 km/hour. This form of charging is referred to as Level 1.
Charging at an accelerated rate, using a 240v circuit, brings us to Level 2 and Level 3 charging.
 
To get the most from your Electric Vehicle Supply Equipment (EVSE), it’s important to identify your needs; For example, the amperage required by your vehicle to obtain a charge. Given the pace at which technology evolves, we recommend choosing a charger that has multiple amperage output options and is capable of at least 30 amps.
 
Finally, you may wish to consider some additional features that are available. Do you need the ability to set charge times? In areas where hydro is charged at different rates during the day, this may allow for additional cost savings.
 
Could you benefit from having the ability to connect to your EVSE via your smartphone, thereby allowing you to receive notifications when charging is complete or if an issue occurs requiring your attention?
 
How far will your vehicle be from the EVSE while charging? Connector cords are typically available in lengths from 15-25 feet.
 
Will your charger be installed indoors or outdoors? Most electrical codes require an outdoor unit to be hardwired, while an indoor unit may simply plug in, which allows for easy removal in the future.
