The BMS Tester Trusted by Leading BMS Test and Development Engineers

Why Reliable BMS Testing is Important

Your Battery Management System (BMS) is at the core of ensuring battery safety, efficiency, and lifespan in your electric vehicle’s battery. However, unreliable BMS functional testing can lead to costly delays, safety risks, and lost trust. With the right BMS tester, you can avoid these issues and stay ahead of the curve.

Every BMS is unique, but the challenges remain the same:

How do you ensure electrical safety and performance without wasting time or money?
How can you simulate real battery conditions accurately?
Can your testing process keep up with the pace of innovation?

With comemso’s advanced BMS tester, you can confidently optimize your testing process, achieving precise and efficient BMS testing. Discover how our solution helps you meet these challenges head-on and elevate your testing game.

How to test Battery Management Systems?

Welcome to our “Testing of Battery Management Systems (BMS)” video! In this video, we walk you through the essential processes for testing and validating high voltage Battery Management Systems (BMS). You’ll learn how to simulate battery cells and test critical BMS functions, including active and passive balancing, electrical fault injection, temperature sensor emulation for environmental conditions, and isolation fault injection. Using advanced tools like the comemso Battery Cell Simulator (BCS), this video demonstrates how to ensure your BMS performs reliably and safely, addressing real-world challenges such as thermal behavior, fault detection, and performance under varying conditions. Watch now to discover how to optimize and validate your BMS testing procedures effectively!
