Types of Chargers

Purchasing a Charger

If you are in the market for a charger, you should determine how fast you want your charger to be and what’s your price range. Generally, every 10 amps at 240 volts means up to an additional 10 miles of range per hour.  Also, if you get a Level 2, you need to have a professional electrician install it and ensure your residence has the infrastructure to support it. 

EV chargers need to be UL certified. It’s important to ensure they are safe and have passed all the mandatory guidelines. 

Also, there are a few models that have Wi-Fi connectivity. These chargers can be monitored and controlled by your smartphone.

Connectors

All EVs except Tesla use the same J1772TM connector for Level 2 charging. Tesla makes adapters that allow their vehicles to charge using J1772 and CHAdeMO connectors. Not all EVs have the option to use a DC fast charger, and sometimes it is available as an upgrade option. Be sure to research your model.

Types of Chargers

There are three types of electric vehicle (EV) chargers on the market. Depending on your car model, you’ll need to decide which charger works for your car and your lifestyle.
