MAHLE opens UK facility for electrified powertrain battery pack and module testing

As a response to the growing time and cost pressures facing vehicle manufacturers seeking to develop latest generation automotive electrification technologies, MAHLE Powertrain has opened a new, dedicated facility for the extensive testing of battery modules.

The facility, based at the powertrain specialist’s Northampton (UK) technical center, enables the strip-down and disassembly of modules and compact vehicle batteries for post-test assessment, and provides a climate-controlled environment to carry out real-world simulated testing with the aim of streamlining the test and validation stages of emerging technologies.

As well as offering post-assessment suitability analysis, the battery pack assembly and testing facility enables testing under simulated drive-cycle conditions to evaluate the performance of battery systems in real-use environments. Included within the testing remit is the ability to assess cells, modules and battery packs for steady state testing of open circuit voltage, storage capacity and thermal characteristics, including voltage response under high discharge, thermal behaviour and internal resistance.

Assembly of new prototype units is also possible at MAHLE Powertrain’s new highly modular facility, which can conduct dynamic test cycles and steady state characterization testing with or without battery management systems in-situ. The facility can conduct tests within the temperature range of -40 ˚C to 100 ˚C with precise humidity control and protection from a EUCAR 5 fire detection and suppression system. The remote-control chamber receives bi-directional power supply suitable for module testing with cycling software and control of the environmental chamber.

As a services subsidiary of the MAHLE Group, MAHLE Powertrain has eight technical centers strategically located in the UK, Germany, US, China and Brazil and is well-placed to provide solutions around the globe. It operates independently of the main group when considering choice of components or technologies.

The MAHLE Group is well-known as a leading international development partner in the areas of engine systems, filtration, mechatronics and thermal management. It formed MAHLE Powertrain from the acquisition of the Cosworth powertrain development team in 2005.
