Electrified Propulsion Testing

Testing every aspect of electrified propulsion for electric and hybrid cars including whole vehicle, system level and component level tests.

Manufacturers and retailers of electric and hybrid vehicles need to be sure that the propulsion systems used are able to cope with the everyday demands of motorists around the world. From testing a battery’s range to its ability to withstands extremes of hot and cold, SGS’s ISO/IEC 17025 accredited laboratories are equipped with the latest technology to test whole vehicles, electrical systems and component parts.

We operate advanced chassis dynamometers with all-wheel and two-wheel drive capabilities that simulate driving conditions for custom driving patterns or standard road cycles. We also test vehicles and components against a multitude of simulated environments including road, temperature and altitude to ensure safety and durability throughout their lifespan.

Vehicle testing capabilities

Our testing centers offer options for drivability with the choice of certified technical drivers or automated robot drivers. Such precision is crucial to vehicle and battery manufacturers seeking accurate range and state-of-charge measurements in the development of electric or hybrid cars.

Additionally, we offer the following related vehicle and component testing services:
