charge and load management systems
• Local and remote configuration
3.2 Product description
The charge controller monitors charging system internal hardware, such as the meter, the
user interface board or the socket. It is characterized by its compact design and size that
in turn enables intelligent, small and cost effective charging systems. Several product va-
riants are available and an overview of these variants is given in Chapter 3.2.1.
To enable the charge controller to communicate, a backend system is required. Given
that most backend providers strictly adhere to the OCPP communication protocol, the
charge controller is OCPP compliant. All specified messages in OCPP are supported as
well as some vendor-specific extensions based on the DataTransfer message. 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 as an
"always on" system that is always connected to a mobile network. The controller supports
4G mobile networks. Connectivity for online operation requires a SIM card (which is not
included in delivery). User interaction is facilitated using an RFID module, which consists
of an RFID card reader and LEDs. Charging is initiated by holding a valid RFID card close
to the reader. In offline operation, the charge controller can optionally allow charging
without authorization or it can authorize users based on RFID and a local white list of
authorized RFID cards.
