AC vs DC Chargers

AC chargers supply alternating current and are used for home charging at speeds from 7kW to 22 kW. DC chargers supply direct current and are used for fast commercial charging from 25 to 420 kW. Homes use AC chargers while many businesses and public sites use DC chargers.

AC chargers are for homes.
DC chargers are for commercial fast charging.
AC power is converted to DC inside the vehicle which then charge the vehicle’s battery.
DC chargers bypass the onboard charger by converting electricity before reaching the vehicle.

AC chargers explained

AC chargers are the standard home charging method. They rely on the vehicle’s onboard charger to convert AC to DC. This limits the speed to between 7kW and 22kW depending on the vehicle and supply type.

DC chargers explained

DC fast chargers convert AC to DC externally and feed power directly to the battery. This enables very high charging speeds but requires large electrical infrastructure which is not suitable for homes.

Recommended models

AC: Ocular IQ Home Solar Universal and Ocular LTE Plus.

DC: Ocular Titan or Ocular Atlas

Is AC safe outdoors?

Yes with weather rated units such as Ocular chargers.

Do all EVs support DC?

Yes all current EVs do, but speeds vary depending on the vehicle.

Does DC charging harm batteries?

DC charging has a very small effect on battery health compared to AC charging, especially for average EV drivers. There is a greater effect on wear and tear for vehicles operating high-use duty cycles similar to high-use petrol vehicles.
