Starting the charging process

1. insert the plug into the gray ring and turn it approx. 60 degrees to the left.

Hold the RFID charging card in front of the identification field. The charging process is started.

Stopping the charging process

Open the vehicle. The charging process is stopped.

Remove the plug from the socket.

The advantages of the AC charging station with 22 kW charging power

The advantages for users

Up to 2 vehicles can be charged simultaneously at the charging station. The large color display enables intuitive operation and a convenient overview.

In addition, a barrier-free design ensures easy access for users with limited mobility.

The charging process is accomplished in just a few simple steps, and payment is quick and easy thanks to the HecPay terminal.

HecPay: Contactless and secure payment

With HecPay, users start their charging processes cashlessly via credit or debit card as well as mobile payment. The large touch display, a physical pinpad and a digital receipt output allow intuitive and convenient operation.

Charging point operators can enjoy low investment and operating costs, because a single HecPay terminal controls any number of charging points. Another advantage is the sturdy housing and robust touch display for reliable outdoor use.

Retrofitting existing charging points is also no problem, as HecPay supports common OCPP backends and can thus be easily integrated into existing charging infrastructure. All HecPay terminals can be managed and controlled via a modern SaaS solution.

Further advantages for charging station operators

Thanks to an optionally integrated mains junction box and meter measuring field, the charging pole can be connected directly to the distribution network and there is no need to install an additional costly junction box. At the same time, it impresses with a robust, secure design that reliably protects against vandalism and prevents unpleasant follow-up costs.

Thanks to the integrated dynamic load management, the power available at the grid connection can be distributed to up to 250 charging points. Thanks to the possibility of integrating an external electricity meter, external loads such as power consumption in the building can be taken into account. This means that your customers always charge with the best power.

Via OCPP 1.5 or OCPP 1.6, the charging pole can be connected to any software backend and billed. The connection is made simply via the intergated mobile modem or the LAN connection. The eye also charges: The attractive design of the charging pole strengthens the general appearance and at the same time offers the possibility of individual foiling to increase the recognition value.

The charging station is compliant with calibration law: But what does that mean anyway?

Since 01.04.2019, electric power at public charging stations in Germany may only be billed if the requirements of calibration law are met. This is intended to ensure that the amount of energy billed is correct and transparent traceable is. It must always be apparent to users:

  • How much electrical energy they have drawn
  • and how much time the charging process took.

In addition, the transmission of the measured values from the charging station to the backend must be evidence-proof and in compliance with data protection regulations. With the transparency software of S.A.F.E eV, users have the possibility to check the validity of the digitally signed measured values of the charging processes and to ensure that the invoiced values have not been manipulated by third parties.

These requirements are based on the German Measurement and Calibration Act (MessEG), the German Measurement and Calibration Ordinance (MessEV) and the German Price Indication Ordinance (PAngV). The Amperfied connect.public fulfills all requirements for charging in compliance with calibration law.

A 22 kW charging pole with outstanding connectivity

A charging station would be nothing without a reliable and high-quality charge controller. As the heart of every smart charging station, a charge controller communicates with the vehicle and the backend, monitors the internal hardware of the charging system, the user interfaces, and the connection from the charging station to the vehicle. We at AMPERFIED are pleased that we were able to implement an innovative and reliable product with the latest generation of intelligent charge cont rollers - the CC613 from Bender GmbH.

Bender GmbH is a valued partner whose charge controller technology has already been able to convince in more than 20 commercial backends and, among other things, guarantees high connectivity (EEBus, ISO 15118, OCPP 1.6) and enables overarching dynamic load management.

With the charging station, electric and hybrid vehicles charge quickly

The Amperfied connect.public is an AC charging station that enables convenient, fast charging with alternating current with a charging power of up to 22 kW. Higher charging powers are required at freeway service stations, for example. These charging stations (with up to 350kW) are DC charging stations (direct current).

Compared to AC charging stations, these are significantly more expensive and place a much greater demand on the power grid. Therefore, for locations where the car is parked for longer periods of time (e.g., restaurants, shopping centers, or public parking areas), AC charging stations are often the better choice.
