An AC charger is a type of electric vehicle (EV) charger that supplies alternating current (AC) to an EV, where the vehicle’s onboard charger converts it into direct current (DC) to charge the battery. Because this conversion happens inside the vehicle, the charging speed depends on the EV’s onboard charger capacity.

AC chargers are widely used for home charging, workplace charging, and destination charging due to their cost-effectiveness, easy installation, and suitability for long parking durations. They typically operate between 3.3 kW and 22 kW, making them ideal for overnight charging, daily top-ups, and routine EV usage.

While AC charging is slower than DC fast charging, it is generally more battery-friendly for regular use, helping maintain long-term battery health. Common connector types include Type 1 (SAE J1772) and Type 2 (Mennekes), with Type 2 being the standard in many regions.

In simple terms, an AC charger delivers alternating current to an EV, which is then converted into DC by the onboard charger, making it best suited for home and long-duration charging.

AC chargers play a crucial role in the EV charging ecosystem by enabling convenient, reliable, and accessible everyday charging infrastructure, especially in locations where vehicles are parked for extended periods.
