IEC 62196 Misalignment Test Apparatus for EV Charging Connector 4-direction Servo Force Test

Product Overview

This misalignment test rig is purpose-built for EV conductive charging coupler safety validation, fully engineered to satisfy IEC 62196-3:2026 clause 36 and IEC 62196-1:2025 clause 36 (Figure 28, 29). It is widely used by EV charging gun manufacturers, EVSE labs, third-party certification testing laboratories across Europe, Southeast Asia, Latin America.

The misalignment test is a mandatory mechanical safety test after temperature rise stabilization. It simulates uneven external mechanical stress on charging plugs, vehicle connectors and inlets under real misplug scenarios. The machine applies calibrated static force sequentially along four axes (-X, +X, -Y, +Y), automatically holding force, pausing and switching directions without manual intervention. It adopts dual servo motor X-Y sliding platform + high-precision force sensor closed-loop monitoring, ensuring stable, repeatable test results for certification reports.

Core Test Principle

After the specimen completes temperature rise test and temperature stabilizes, the apparatus applies mechanical load to the charging accessory. Standard reference load is 100N (tolerance -0/+10N) per direction. Each direction maintains load for minimum 1 min; after unloading, a 10-second interval is reserved before loading on the next axis. The cycle runs through all four directions (-X, +X, -Y, +Y) as defined in IEC standard drawings. The PLC + touchscreen system records force curve data during the whole test cycle, easy for export and audit for IECEE, CB, CE certification.
