What is AC charging?
AC charging is a common way to charge an electric vehicle using alternating current electricity. This is the same type of electricity supplied by homes and many buildings. When an EV uses AC charging, the vehicle’s onboard charger converts that AC power into DC power so it can be stored in the battery.
AC charging is usually slower than DC charging, but it is often cheaper, simpler and well suited to longer parking stays. It is commonly used for home charging, workplace charging and destination charging at places such as hotels, shopping centres and public car parks.
Why AC charging matters
For many EV drivers, AC charging handles most day-to-day charging needs. If the car is parked for several hours or overnight, fast charging may not be necessary. The actual charging speed depends on the charger output, whether the site has single-phase or three-phase power and the vehicle’s onboard charger limit.
On Penguin Power, AC charging information helps drivers understand whether a location is useful for a long stop, an overnight stay or a top-up while doing something nearby.
