GKN Automotive develops real-time EV test rig

Installed at GKN Automotive’s Offenbach facility, the company said its new rig 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 and dynamically control speed and torque to replicate wheelspin and other complex driving conditions. 

GKN Automotive believes this can set a new industry standard for precision and quality control in the testing of EV components, enabling engineers to deliver lighter and more efficient solutions with no compromise on capability.

Described as ‘cutting-edge’, the rig requires high levels of GKN engineering expertise for correctly setting up and executing tests. Data must be selected and validated by the team to establish parameters for the test, and the system must be carefully calibrated during set up to accurately replicate precise load dynamics.
