EV Charger is a common name for Electric Vehicle Supply Equipment (EVSE), which is a tool used to supplement electric energy for electric vehicles.
The power battery of an electric vehicle can only receive direct current (DC) voltage, while the power grid/household socket provides alternating current, which requires AC-DC conversion before charging the battery.
The direct current (DC) charger integrates a power module, which performs AC-DC conversion inside the charger and outputs DC power to charge the battery.
