As we've learned, power from the grid is always AC. The difference between AC charging and DC charging is the location
where the AC power gets converted --- inside or outside the car. Unlike AC chargers, a DC charger has the converter inside the charger itself.
That means it can feed power directly to the car's battery and doesn't need the onboard charger to convert it. DC chargers are bigger, faster,
and an exciting breakthrough when it comes to EVs.
