Not a charger itself, an EVSE is a key piece of EV charging equipment that connects to the charger in your electric car.

The first task your car's built-in charger tackles is taking the AC current supplied at most charging locations and converting it to the DC current that batteries can ingest. This is similar to what your phone's charger does with AC from a wall outlet, converting it to the 5.0 volts DC that is part of the USB standard. Unfortunately, electric cars don't have a spec like USB to make their charging uniform.
