Charge controller

The Charge Controller CC612 combines the electrical safety requirements of AC charging points with the vehicle charging requirements.

It is optionally available with an AC/DC sensitive residual current monitoring device.Monitoring is done via an externally connected shielded current transformer which isconnected to the CC612. Thereby, the requirements of the standards series DIN VDE 0100 or rather DIN VDE 61851 regarding protective measures directly in the Charge Controller are complied with. A residual current device (RCD) type A can be used in the infrastructure.The measured values are available to the backend system via the integrated modem.

Due to its compact structure and size (114.5 mm x22.5 mm x 99 mm), the Charge Controller makes intelligent, small and cost-effective charging stations possible. To communicate with the Charge Controller, a backend system together with a well-known and reliable communication protocol is required. Since most of the backend device manufacturers use the OCPP communication protocol, the Charge Controller is compatible with OCPP-1.5 and with all electric vehicles currently present on the market.

Integration tests with the backend implementations of providers such as Vattenfall, Bosch, NTT and DRIIVZ have been successfully carried out. The Charge Controller can be operated in an "Always-on system", which is always connected to a mobile network. The controller supports 2.5G Edge and 3G UMTS mobile networks. For connection to online operation, a SIM card is required. User interaction is facilitated using an optional RFID module, which consists of an RFID card reader and LEDs. Charging is initiated by either holding a valid RFID card close to the reader or remotely by the backend system via OCPP. In offline operation, the charge controller can optionally allow charging without authorisation or it can authorise users based on RFID and a local white list of authorised RFID cards.
