Battery Testing: Longevity, Durability and Efficiency

As lithium-ion pouch or prismatic cells get older, they begin to swell — building up internal pressure. This swelling directly affects battery performance, health, and lifespan. The problem? Most battery management systems don’t monitor pressure at all. That leads to miscalculations, reduced performance, and shorter battery life. Traditional testing setups using climate chambers and passive fixtures fail to precisely control temperature and pressure — two critical factors for accurate battery testing. That’s why ZwickRoell and MBTS developed a revolutionary solution: a fully integrated test bench that actively controls temperature, pressure, and electrical performance — all at once. Why is that so important? Batteries are dynamic systems. They expand when charging and contract when discharging. Too much or too little pressure accelerates degradation. And temperature amplifies these effects. This new system allows engineers to simulate real-world conditions with micrometer-level precision — revealing valuable insights.
