When it comes to electric mobility, two types of electrical currents can be used to charge an electric vehicle (EV)—AC (alternating current) and DC (direct current).
All home EV chargers and the majority of public charging stations use AC, while DC is used for fast charging.
When we talk about charging an EV, the main difference between AC and DC charging (and the time it takes to do so) is where the conversion from AC to DC happens, i.e. in the vehicle or the charging station.
- The power that comes from the grid is always AC (alternating current).
- The energy stored in batteries is always DC (direct current).
This article explores the differences between AC and DC EV charging and takes a look at how it works.
