Universal EVSE Controller PCB Design
Budget: ₹1,500 – ₹12,500 INR
Universal EVSE Controller PCB – Freelancer Requirement
Design a universal ESP32-based EVSE controller PCB for AC EV chargers.
Same PCB must support 3.3 kW, 7.4 kW, 11 kW, and 22 kW chargers.
Use ESP32-WROOM-32E as the main controller.
Include Ethernet (LAN8720), RS485 Modbus, RFID (RC522), and optional 4G module header.
Implement IEC 61851 Control Pilot (CP) and Proximity Pilot (PP) circuitry.
Provide contactor control output, emergency stop input, and temperature sensing.
Support OCPP 1.6J firmware integration.
PCB size approximately 120 mm × 90 mm, 4-layer industrial design.
Separate low-voltage control section from high-voltage interface section.
Follow proper EMI/EMC, creepage, and clearance requirements for EV charger applications.
Deliver KiCad source files, schematic, PCB layout, BOM, Gerber files, and assembly drawings.
PCB should be production-ready for mass manufacturing.
Controller PCB only; high-current AC power path (MCB, RCCB, contactor, Type-2 socket) will be external.
Design should be scalable for future features like OTA updates, QR charging, load balancing, and ISO 15118 support.
Target compliance with IEC 61851, AIS-138, and BIS-related EV charger requirements.
