Smart Electric Vehicle Charge Controller

It's an open source EVSE (Electric Vehicle Supply Equipment). It supports 1-3 phase charging, fixed charging cable or charging socket. Locking actuator support (5 different types). And it can directly drive a mains contactor for supplying power to the EV. It features a display from which all module parameters can be configured.
Up to 8 modules can be connected together to charge up to eight EV's from one mains connection without overloading it.
The mains connection can be monitored by the (optional) sensorbox or a modbus kWh meter. This allows smart charging. Communication between the SmartEVSE(s) / Sensorbox or kWh meters is done over RS485(modbus).

• Fits into a standard DIN rail enclosure.
• Measures the current consumption of other appliances, and automatically lowers or increases the charging current to the EV. (sensorbox required)
• The load balancing feature let's you connect up to 8 SmartEVSE's to one mains supply.
• Two switched 230VAC outputs, for contactors.
• Powered RS485 communication bus for sensorbox / Modbus kWh Meters.
• Can be used with fixed cable, or socket and charging cable.
• Automatically selects current capacity of the connected cable (13/16/32A)
• Locking actuator support, locks the charging cable in the socket.
• RFID reader support, restrict the use of the charging station to max 20 RFID cards.
• An optional modbus kWh meter will measure power and charged energy, and display this on the LCD.
• Built-in temperature sensor.
• RGB led output for status information while charging.
• All module parameters can be configured using the display and buttons.
• WiFi status page.
• Firmware upgradable through USB-C port or through the built in webserver.
