Extend existing Charge controller for charging Electric Vehicles with OCPP and WiFi communication

Extend an existing charge controller for charging Electric Vehicles with Wifi and communication with an OCPP Backend.

I want to make an existing semi smart charge controller capable of configuring trough wifi and able to communicate with an ocpp Backoffice. I want to remove the screen and configuration only trough wifi.

Capabilities today are:

- Smart charging capable, reduces charging current when demand elsewhere increases.

- The load balancing feature allows you connect up to 4 controllers to one mains supply.

- Switched 230Vac output, for contactor/relay.

- Can be used with fixed cable, or socket and charging cable.

- Automatically selects current capacity of the connected cable (13/16/32/63A)

- Locking actuator support, locks the charging cable in the socket, automatically unlocks on a power failure.

- Powered RS485 communication bus.

- Built-in temperature sensor.

- All module parameters can be configured using the display and buttons.

- Firmware upgradable.

- The controller operates at a mains voltage from 110-240Vac

Important part is this:

The controller will be build with the following service => [login to view URL]

So you will need a bom and gerber file.

You will also be able to see if the parts are available and common.

The project of the existing controller is located at the following address:

It is this controller I want you to extend and rewrite

THE CONTROLLER SHOULD MAINTAIN ITS EXISTING CAPABILLITIES AND MUST BE ABLE TO COMMUNICATE WITH AN OCPP BACKEND
