The types of chargers for electric vehicles are divided into two main groups: alternating current (AC) chargers and direct current (DC) chargers.
The major differences between them are the type of connector used and the maximum output powers.
Alternating current (AC) chargers
The correct name for this type of chargers is Charging Station or SAVE (power supply system for the electric vehicle), as it is well established in the regulations, since the AC/DC converter is located inside the electric vehicle.
In any case, they are usually defined by the type of connector they incorporate (Type 1; Type 2), the charging mode (Mode 2; Mode 3), the type of mounting (wall-mounted; pole-mounted) and the maximum output powers, which range from 3.7 kW in single-phase to 44 kW in three-phase.
Direct current (DC) chargers
This type of charger injects direct current directly from the charging station to the electric vehicle, passing the vehicle’s on-board AC/DC converter. In this way, higher power loads can be carried out and charging times are shorter.
The AC/DC converter, control and communication devices and electrical safety protections are located inside the charging station. Maximum power outputs can range from 22 kW to 350 kW.
