Automated EV Power Conversion Validation

Modern electric vehicles rely on complex power electronic units, including bi-directional On-Board Chargers (OBC), high-voltage DC-DC converters, and main traction motor inverters. Operating at voltage levels up to 800V and higher, these components require rigorous testing during both design validation (DVT) and high-volume mass production.

Chroma's Automated Test Systems (ATS) combine high-precision bi-directional DC sources, regenerative AC electronic loads, and power meters into a cohesive, open-architecture software environment (PowerPro 5). Enjoy reduced test execution times, automated data collection, and ISO-compliant reporting.

  • Bi-directional power flow testing for V2G, V2L, and V2H validation.
  • Up to 92% energy regeneration back to the grid for maximum operational cost reduction.
  • Built-in safety interlocks for high-power, high-voltage lab environments.

High-Voltage Electrical Safety & Hipot Testing

With EV battery architectures pushing operating thresholds up to 800V and 1000V, electrical insulation safety is vital to prevent catastrophic short circuits and protect passengers. Compliance with international standards such as UL 2594, IEC 60601-1, and ISO 6469 demands precise safety analyzers.

Chroma's electrical safety analyzers execute AC/DC Hipot, Insulation Resistance (IR), Ground Bond (GB), and Leakage Current testing in a unified sequence. Advanced Partial Discharge (PD) measurement detects microscopic insulation defects in EV connectors, busbars, and battery jelly-rolls long before electrical breakdown occurs.

  • Model 11210: High-speed battery cell insulation tester with PD/Flashover detection.
  • Multi-channel switching modules for high-throughput production line automation.
  • Precision ground bond testing up to 40A to guarantee vehicle chassis earthing integrity.

Chroma Hipot Safety Analyzer
EV Traction Motor Stator Testing

EV Traction Motor & Wound Component Testing

Traction motors operate under intense thermal stress and high switching frequency voltage spikes (dV/dt) from SiC inverters. Over time, corona discharge between motor stator turn-to-turn insulation leads to premature winding breakdown.

Chroma’s Wound Component EST Analyzers (Model 19036) integrate impulse winding surge tests with high-frequency resonant waveform analysis to identify latent stator insulation flaws, turn-to-turn shorts, and magnet wire pinholes before motor assembly.

  • High-voltage impulse surge test up to 10kV with Area Size Comparison (AREA) calculation.
  • Corona discharge detection preventing long-term motor reliability field failures.
  • 4-terminal Kelvin resistance measurement for micro-ohm stator coil resistance accuracy.
