EV charging devices - general

In most cases a domestic charger is mounted on a wall or similar supporting structure. If necessary the device can be mounted, using a separate adapte for installation, e.g. on a pole such as is used for engine block heaters.

Business chargers serve several users and different makes of vehicle. The charger is equipped with a charging socket (Mode 3 Type 2) designed for EV charging. Since the charger is situated in a public place in this case, restriction of use and verification of energy consumption may be among the essential features. Smart charging devices are generally used in business charging. Business chargers are typically installed at places of work, indoor car parks, shopping mall car parks, retail shop car parks, and other locations which serve the public.

• The current of Business chargers varies from 1 x 6A to 3 x 63A
• The most typical installations used are 3 x 16A (11kW) and 3 x 32A (22kW). These charging currents enable sufficient charging in relation to the time in use at the site.
• The intelligence of the Business charger allows control of the charging currents, depending on the total load at the site.
• A specially designed charging centre is usually installed for EV charging at locations where there is a need for Business chargers.
• The charging centre makes the system into an independent unit that is easy to control and, if necessary, the extent of the system can be seamlessly increased.

Business chargers are installed on a wall if possible, but the majority of e.g. car parks at places of business require installation either in the floor or in the ground. Thus the device can either be mounted onto a separate charging pole, or a device is selected with a supporting base. A charging pole installed in the ground can serve side-by-side or end-to-end car park spaces.

• Fast/power chargers are suitable for service environments, catering for the immediate requirements of the electric vehicle.
• A fast charger can fully charge a battery in less than half an hour.
• The typical charging wattage of the present fast charging devices is 50kW, but in the near future this will be increased to 125kW. In practice this means a supply current to the charger of up to 300A.
• Fast chargers are equipped with fixed charging cables. There are two different types of charging cable - CSS ja CHAdeMO - and in general both can be found in public fast charging devices.
• Of these, the European standard CCS cable provides a charging power of 120kW (400V), and the CHAdeMO provides 63kW.
• There is usually a fee for charging on a fast charger, and this is organised by a charging operator.

Almost without exception, a fast charger is installed in the ground, either in an existing foundation or on a cast concrete foundation. The device operates in the same way as a Business charging pole, either at side-by-side or end-to-end parking spaces.
