The cFos Power Brain Controller is a controller for installation in a wallbox for charging electric cars according to IEC 62196 (type 2). For this purpose, the cFos Power Brain Controller monitors the "Charge Pilot" (CP) and "Proximity Pilot" (PP) signals of the connection cable to the wallbox.
The cFos Power Brain Controller is a charge controller and has the following components:
At the heart of the cFos Power Brain Controller is an ESP32 from Espressif Systems. With the help of this powerful microcontroller, the cFos Power Brain Controller can speak the following communication protocols:
You can therefore use cFos Power Brain Controller to build a EVSE that speaks OCPP and Modbus at the same time and can also be controlled via an HTTP API. Such EVSEs can then be easily networked via WiFi
The cFos Power Brain controller can read meters via Modbus, e.g. the ABB B23 112-100 (but also others according to your wishes) or up to two S0 meters via the S0 inputs. These inputs can also be used as switching inputs for control purposes. You can equip the wallbox cost-effectively with an intermediate meter for billing purposes and at the same time optionally read other meters from consumers or generators (solar system).
Of course our own EVSE uses the cFos Power Brain Controller.
(1) Only for devices supported by the cFos Power Brain Controller, i.e. only for controllers installed in large numbers in EVSE EVSEes from OEM partners. For the cFos Power Brain Wallbox, only the respective scope of equipment described there applies.
(2) The inputs can be controlled via a potential-free switch. The cFos Power Brain Controller supplies 12V voltage for this purpose.
