Understanding the Fundamental Difference

When planning an EV charging deployment, selecting the right charger topology directly impacts upfront substation costs, cabling infrastructure, and customer satisfaction.

When to Choose AC Destination Charging (7.4kW - 22kW)

AC chargers are best suited for long-dwell locations such as residential townships, corporate offices, hotel parking lots, and overnight fleet depots where vehicles remain parked for 4 to 8 hours.

When to Deploy DC Fast Charging (30kW - 240kW)

DC chargers bypass the onboard vehicle converter and deliver direct current directly to the battery pack, providing an 80% top-up in 20 to 45 minutes. Ideal for highways, fuel stations, and high-turnover retail hubs.
