Project overview

AC-input EV charging controller board that manages power delivery from a 220VAC mains supply, handling the control and safety logic between the charger and the vehicle.

Engineering approach

Automotive and vehicle-adjacent hardware has to keep working through vibration, temperature swings, and electrically noisy environments that consumer electronics never see. On this board, that translates into a component set built around 220VAC Input and EV Charging, with layout and stack-up decisions driven by vibration resistance, wide operating temperature range, and robust connector and harness interfacing.

Front and back of the 220V AC EV charging controller PCB: a Delta AA04D0512A AC-DC module with 12V and 5V outputs, terminals labeled 12V, GND, PLT and PP, FTDI and I2C headers, and the microcontroller circuitry on the back — Front and back. The front carries a Delta AA04D0512A AC-DC module (100–240VAC in, 12V and 5V out), terminals labeled 12V, GND, PLT and PP, and FTDI and I²C headers. The back holds the microcontroller and control circuitry, with a marked separation from the AC input area. Click to view full size.
