Charging stations are built by various manufacturers in a variety of forms, and can be wall-mounted, pole-mounted, columns or portable. They can also feature different authorization options. Currently, the most common method is the card with RFID (Radio-Frequency Identification) technology that allows users to unlock the socket of the charging station and start charging the car.
Depending on the relevant sector of application, the charging columns need to meet different requirements. They can generally be divided into two main categories:
Private charging stations
Public charging stations
In the private sector these can be for: single/multi-family homes, shopping malls, shops, restaurants, hotels, car dealers with repair shops, banks/insurance companies and company car parks. Depending on the circumstances, these may or may not be open to the public.
Public charging columns are installed on public roads or in public car parks located at airports, railway stations or other public areas.
There are different types of stations on the market. Typically, those for private use can charge at a power between 3.7 and 22 kW. Public charging stations charge in alternating current or direct current and at a power varying on average from 3.7 to 50 kW.
