AD-ACEVSECRDSET-SL

Type 2 EVSE 3.6 kW Charging Cable

Introduction

The AD-ACEVSECRDSET-SL is a complete Type 2 EVSE 3.6kW charging cable solution, providing a reference design intended for evaluation and prototyping of EV charging systems.

The system includes the ADE9113 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 are also available.

The MAX32655 ultralow power ARM® Cortex®-M4 processor 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.

The design is accompanied by an open-source software stack and reference applications, enabling custom software development to start from a proven implementation validated to meet the applicable standards. The system is designed to meet the IEC61851 and IEC62752 standards.
