Vehicle testing and electrical and electronic subsystems (EEE) - On-board systems
We validate the performance of on-board electrical and electronic systems in electrified, hybrid and thermal vehicles:
- Full vehicle EMC tests: very large Faraday cage (27x18x10.5 m), 4x4 chassis dynamometer up to 1200 km/h, CISPR 12/25, ISO 11451/11452, ISO 7637, ECE R10 tests.
- Electric powertrain testing: motors, inverters, OBCs, BMSs and converters. Electrical, environmental, thermal and EMC validation.
- Battery testing: complete packs, modules and cells, approval tests (ECE R100, ECE R10), abuse tests, endurance, fire, IP, ADR, cycling.
- High Voltage Systems: combined EMC, climatic and vibration testing for HV boxes, connectors, sheaths, etc.
- Low-voltage components: functional and environmental validation of computers, sensors, relay boxes, optics, etc
