Comprehensive testing is the only way to verify the safety, performance, and lifetime of a battery. PEM Motion provides tailored test programs designed to meet the specific requirements of both prototype and series production projects.
We conduct electrical, mechanical, thermal, and safety-related tests. This includes cycle life testing, fast-charging tests, abuse testing, and thermal management evaluations.
Yes. Our experts help analyze test data and translate it into actionable recommendations. This not only saves valuable development time but also reduces unnecessary design iterations.
Timelines depend on the type of test. Thanks to our flexible laboratory infrastructure and strong partner network, PEM Motion can typically achieve very short lead times. We will always find a good solution, if there are time-critical projects.
Beyond development, testing is essential in production – for example, during end-of-line inspections. PEM Motion supports the implementation of efficient testing processes directly into manufacturing workflows.
