Understanding AC EV Chargers

What is an AC EV Charger?

An AC EV charger is a device that converts the alternating current (AC) from the grid into direct current (DC) that your electric vehicle’s battery can use. AC chargers are commonly used in residential settings due to their ease of installation and affordability compared to DC fast chargers.

How Do AC EV Chargers Work?

AC EV chargers work by connecting to your home or office electrical system. Here’s a breakdown of the charging process:

  1. Connection: Plug the charger into the EV’s charging port.
  2. Conversion: The charger converts AC from the grid to DC for the EV’s battery.
  3. Charging: The EV’s onboard charger manages the conversion and distribution of power to the battery.

Types of AC EV Chargers

Level 1 Chargers

  • Voltage: 120V
  • Current: 12-16A
  • Charging Speed: 2-5 miles of range per hour
  • Use Case: Suitable for overnight charging at home.

Level 2 Chargers

  • Voltage: 240V
  • Current: 16-40A
  • Charging Speed: 10-60 miles of range per hour
  • Use Case: Ideal for home and public charging stations, providing a faster charge.

Factors to Consider When Choosing an AC EV Charger

Compatibility with Your EV

Ensuring compatibility between your EV and the charger is crucial. Different EVs require different connectors and have varying charging capabilities. Check your EV’s manual for recommended charger specifications.
