GKN's real-time EV testing rig can replicate complex driving conditions

GKN Automotive has created a ‘real-time’ test rig for electric vehicles which accommodates the differing demands and load dynamics of EVs on driveline components

According to GKN, the rig, installed at its facility in Offenbach, Germany, can handle the extreme dynamics and higher torque of electrified powertrains which make conventional load test rigs unsuitable for driveline parts of the latest generation, such as side shafts.

The ‘real-time capable’ unit can test specific load data provided by customers, from small electric city cars to the most powerful SUVs and is able to dynamically control speed and torque to replicate wheelspin and other complex driving conditions.

GKN Automotive is already providing eDrive systems to more than two million EVs across the globe, with core driveline components selected for use in powertrain systems by a number of the world’s leading manufacturers.

Mario Syhre, Director Product Technology at GKN Automotive, said:

“Electric vehicles place different load dynamics on our driveline components and this new rig allows us to accurately reproduce those to achieve an unprecedented level of testing. Components need to be much stronger to cope with the higher torque and the extra weight of EVs, without increasing significantly in size or weight, and remain as cost-effective as possible. The new rig allows us to accurately replicate the loads on our components, from small electric city cars to the most powerful SUVs, and deliver the lightest, most efficient solution.”
