Heavyweight battery testing
HGV manufacturer Scania has built a laboratory for the development and testing of batteries for heavy vehicles using purpose-built test instruments

halls for battery cells, modules and packs to help achieve its aim. The focus is on battery performance and lifespan evaluation in vari- ous climatic conditions from -40°C to 70°C. The new battery laboratory complements a smaller facility with a climatic chamber for battery pack testing that is extremely flexible because it is basically “outdoors”. With this lab, Scania can test the performance of bat- tery packs on operational electric trucks and buses without removing batteries. Vehicles are parked close to the lab and connected to the testing equipment, or the powertrain can be tested in a huge climatic chamber instead of running real-life winter tests outdoors. Fur- thermore, Scania’s engineers examine the best operational conditions for the battery, considering things such as temperature set- point, state of charge window and charging

Cell Operation Battery and E-components at Scania, the company sees an increasing need to intensify battery testing and tailored de- ployment. By using these modern facilities with appropriate test instrumentation, the laboratory set-up is meeting Scania’s re- quirements. “The need for relevant skills and knowledge
in battery usage and lifecycle optimisation is more important than ever before. Here in the lab, we have the prerequisites to perform our very best in this area,” says Örnhed.
Test Instrumentation /// A key element in the new Södertälje facility in
Sweden is the Keysight Scienlab Battery Test Solution for cells, modules and packs, coupled with a comprehensive safety concept. In ad- dition to Keysight’s Energy Storage Discover software for test and control, Scania has also
made use of Keysight’s PathWave Lab Opera- tions for Battery Test, an integrated, web- based lab management platform that optimises workflow, test throughput and data management. This enables Scania to optimise the planning and coordination of its battery laboratory by managing all resources, includ- ing lab personnel, test systems and devices under test (DUTs). According to Thomas Goetzl, vice-president and general manager for Keysight’s Automo- tive and Energy Solutions division, the goal is to provide comprehensive test systems that help Scania to accelerate and improve its de- velopment activities. “Our collaborative approach with Scania
was to challenge the state-of-the-art, which enabled us to gain insights from a world-lead- ing vehicle manufacturer who strives to dis- cover new edges of e-mobility use-cases and technology,” says Goetzl. The Scienlab SL1700A Series for high-volt- age battery packs of up to 1,500V was pro-
