The CPPP represents a hardware-only State Monitor for safety-redundant emergency stopping of your charger. It consists of the Control Pilot (CP) and Plug Present (PP), forming a communication line used to share information between the car and the charger.
The CPPP Monitor is independent of charging controllers and allows for fast and reliable terminations of charging processes. It does this by opening a trip line relay to trigger an emergency stop if a corresponding signal characteristic is detected, enabling looping of an emergency stop into the trip line.
The state monitor is capable of handling several outlets such as CCS DC, CCS AC or CHAdeMO in parallel, meaning that typically only one CPPP2300 is needed per charging station. All shut down scenarios for AC and DC charging are supported, and additionally an interface to capture shutdown trigger reasons is provided.
The CPPP Monitor offers an IO extender for EcoG’s SECC2300.
The CPPP Monitor offers decreased development complexity in guaranteeing shutdown performance. By aiding in the guarantee of timing performance concerning safe operations, the CPPP Monitor eases the certification process for your charger.
The CPPP Monitor is meant to be used as an additional device to charge controllers to ensure timing performance in accordance with the IEC 61851-23 certification.
12 terminals are provided to facilitate input signal monitoring of all 4 channels, 2x CCS, CHAdeMo and AC, separately. Input signal characteristics according to IEC 61851-1, IEC 61851-23, SAE J1772 or CHAdeMO are supported. To that end, there are inputs for the CP and PP according to IEC 61851-1 and SAE J1772, CHAdeMO CP lines, the plug lock, as well as temperature readings from a four-wire PT1000. Each monitored signal may trigger a tripline through relay output. A DIP-switch enables and disables monitoring.
Optionally, the status of the monitor can be read via I2C, provided as a DIN rail connection using DEGSON FBUS22.5-100A or Phoenix Contact ME 22.5 TBUS.
The CPPP Monitor is independent of charging controllers, however must not be used on its own as the sole component responsible for EVSE switching off. Combined usage with a charge controller is required.
More Solutions & How to Combine Them
EcoG offers its own charge controller – the SECC2300. Together with the CPPP2300, they can be used to enable safety-redundant emergency switching off. The SECC is a charge controller with included communication functionality – it provides circuit control, the charging status and ensures vehicle interoperability.
