What Is an EV Charger?

An EV charger is a device that supplies electricity to an electric vehicle for charging its battery. It connects the vehicle to a power source through a charging cable and plug. Home chargers are often mounted on a wall near the place where the vehicle parks. For more detail, see What Affects the Cost of an After-Hours Electrician Call? Fort Wayne, Indiana.

Local relevance: Fort Wayne winters bring cold weather, which can slow battery charging and influence where a homeowner places a charger near a garage.

Key Takeaways About EV Charger

  • The car controls how much power it accepts.
  • Charger placement affects the wiring route.
  • A wall unit and an onboard charger have different roles.

How EV Charger Works

An EV charger communicates with the vehicle before power flows. The vehicle checks the connection and controls how much electricity it draws. The charging equipment can stop the flow when the session ends.

Most home charging uses alternating current, or AC. The vehicle's onboard charger changes AC into direct current, which the battery stores. The wall unit and the onboard charger work together, but they're separate parts.

Charging speed depends on both the equipment and the vehicle. The vehicle may draw less power than the equipment can supply. Battery conditions and the vehicle's charging settings can also change the rate during a session.

From the Chris Miller Electric team

When we plan an EV charger installation, we check the panel and the home's electrical load. We also look at the route from the panel to the parking area. A charger location should let you reach the vehicle without stretching the cable across your usual path.
