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 [login to view URL] THE CONTROLLER SHOULD MAINTAIN ITS EXISTING CAPABILLITIES AND MUST BE ABLE TO COMMUNICATE WITH AN OCPP BACKEND

Dear Sir, I have checked out github repository and I can help you with your task. We can replace your MicroController to provide Bluetooth and WiFi capabilities while maintaining existing functionalities. Q. Do just just want an extension board that will replace LCD board and pluggable in same socket, or you want a signal board with added capabilities? Note: Github Repo provides Eagle Files but I'll work in KiCad. About Me: I have 6+ years of embedded and IoT system development experience, and my project experience includes access control, medical, power management boards, electronic fluid dispenser, GPS Tracker, BLE localization etc. Looking forward to work with you

Hi, I can develop existing Charge Controller based on "Electric Vehicles" which will be able to communicate OCPP backend for you. I have seen the links which you mention in description. I have humongous experience in EVSE Charge Controller based PCB design and would make the solution cost effective, robust, and efficient. If you are looking for reliable design partner please message me now. I provide services of PCB Design, Circuit Design, Circuit Review, PCB review, Circuit simulation, IOT products development and Sensor conditioning product development. The expertise of mine is in the following fields: 1. Wireless Products – BLE, Wi-Fi, NFC, Lora etc 2. Power Electronics 3. IOT sensors interfacing – Pressure, Temperature, Moisture, PH etc. 4. Microcontrollers- ESP32, STM32, STM8S, RL78 etc. 5. GSM, GPS, GPRS, NBIOT 6. Controller, Electric Vehicle 7. OCPP Backend, Relay 8. EVSE After reading your project details, I have certain queries and suggestions: 1. What is the application of this product? 2. What will be ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? 4. What are the standards that the product would be complying to? Please try to answer these questions based on which I would be providing free of cost consultation. Waiting for your message, Regards Hari Mohan Engineering for one is a magic for others
