AD-ACEVSECRDSET-SL

AD-ACEVSECRDSET-SL is a complete reference design for Type 2 EVSE cordset (IC-CPD) intended for evaluation and prototyping of electric vehicle (EV) charging systems. The system includes a 3-channel isolated sigma-delta (Σ-Δ) ADC for voltage and current measurement on the single-phase power input and measurement of the relay voltage for solder contacts detection and relay state of health. Safe operation is enabled by the inclusion of a 6mA DC / 30mA RMS RCD. Detection of overvoltage, undervoltage, overcurrent, overtemperature and EV diode presence is also available. A MAX32655 low-power, ARM® Cortex®-M4 Microcontroller implements the logic for system control and communication with the EV over the control pilot interface. A programming and debugging interface are included. The MAX32655 Bluetooth 5.2 interface enables connectivity to external devices.
