Electric vehicles will play a key role in future mobility. But the speed at which they catch on depends crucially on the charging infrastructure. One decisive aspect in their acceptance and usability is the market-ready development and standardisation of the charging infrastructure. A secure, user-friendly, comprehensive and efficient charging infrastructure is of utmost importance, both for the potential users of electric vehicles and for planners, operators and energy providers. This is why Weidmüller attaches particular importance to simple installation and high levels of availability as well as reliability and acceptance when developing its charging stations.
Quickly on the wall with the Weidmüller AC wall-mounted charging stations
The AC wall-mounted charging station is particularly well-suited to use in private garages and parking facilities in single and multi-family houses as well as in commercial premises. It combines a high level of efficiency with a good charging speed and an attractive look. In the basic design with type-2 connectors, the stations are available in two different versions: with an attached cable or with a socket. One particular benefit of the WM charge wall H AC11P model is the second socket for the flexible positioning of vehicles while charging.
In accordance with standard DIN VDE 0100-722, a separate residual current device must be installed for each charging point. The DC residual current circuit breaker is permanently integrated in all AC wall-mounted charging stations. Weidmüller also offers an optional configuration with a permanently installed residual current circuit breaker. In order to ensure effective maintenance, there is a maintenance flap installed behind the easy-to-remove design panel. This means that the residual current circuit breaker can be checked annually (Test button) or reset at the end user’s premises without having to call in a technician.
Weidmüller also provides the option of using the established NFC method for authentication. This involves each user receiving an RFID card which is simply held in front of the reader installed in the box in order to unlock it. All AC wall-mounted charging stations are available in performance levels 3.7/11/22 kW.
All wall-mounted charging stations are characterised by a particular design, meaning that the round design covers on the AC charging station can be customised with images as desired. Each wall-mounted charging station also features an integrated, easy-to-access switch, which can be used to shut down the entire charging station, thereby preventing the consumption of quiescent current.
A real “retro-fit”: the AC charging station
Weidmüller developments are based on customer requirements. This applies not only to technology but also to the optimal integration of charging stations into their surroundings. One customised solution is the “retro charging station”. With this product, Weidmüller has combined state-of-the-art charging station technology with the charming design of a classic parking meter. The charging station is particularly suitable for private applications and public parking bays, such as in historical town centres or in front of a private half-timbered house. The retro AC charging station is available in performance levels 3.7/11/22 kW.
An NFC reader is installed in the charging station as standard, meaning that charging can only be authenticated and started by selected people with their own charging card. This safety feature can be deactivated through simple software coding if not required. To allow for connection in private homes, Weidmüller has managed to integrate all of the relevant components into the head of the parking meter, meaning that there is no need for an additional control box on the station. The integrated DC residual current circuit breaker and the convenient management via the backend infrastructure ensure easier commissioning, configuration, maintenance and operation.
