Competition in the automotive industry and the speed of development in hybrid drive technologies are prompting manufacturers to invest in research and development of batteries. Time to market is critical, whereas thorough product testing of batteries should not be neglected, as vehicle recalls are associated with significant costs.
During their long life, batteries and their subsystems, such as connections, cooling, etc., are susceptible to failures that can range from a decrease in battery performance to complete failure. Since batteries for electric and hybrid vehicles exist in a wide range of sizes, shapes, weights and chemical compositions, different test methods are critical to verify durability. The three main battery types are battery cells, modules and packs.
In compliance with major regulations and standards for hybrid and electric vehicle batteries such as ISO, MIL and USABC, mechanical, electrical, environmental and chemical testing must be performed on the battery cells, modules, packs and subsystems.
HBK offers a battery testing solution for mechanical vibration testing, thermal testing and electrical testing – sold separately or packaged.
In addition to vibration test simulation, physical vibration testing of a vehicle’s battery and its subsystems is crucial.
HBK LDS vibration test systems enable a turnkey solution for altitude, mechanical vibration and shock testing including regulations UN 38.3 and ECE Reg 100, which state that before any battery cell, module or pack can be transported, it must be tested under the dangerous goods act. There are, however, many other regulations which apply to different countries, and in turn focus on different technology/battery types (cells, modules, packs, etc.).
Since different battery types and their subsystems have different sizes, weights and required vibration test profiles, a powerful and versatile system is critical. The system must be easily adaptable to multiple testing demands to simulate the life of the vehicle.
But that’s not all. As durability testing is often repetitive, the vibration test solution needs to be easy to set up, conduct and sign off, ensuring that the test is accurate and consistent throughout.
To strictly control the humidity and temperature during vibration testing, a climatic chamber can be integrated. Moreover, HBK turnkey solutions enable a simultaneous measurement of mechanical vibration and thermal/power cycling of a battery.
From the sensors and transducers, the data acquisition and integration to the analysis software, with HBK vibration test solutions you can test the durability of your batteries fast and effectively.
The purpose vibration testing batteries, especially during charge & discharge cycles, is to evaluate the effect of long-term vibration profiles – representative of driving – on the battery, both in terms of the durability and in terms of identification of design flaws. In the recorded webinar you will get to know the core requirements for vibration testing batteries, how to overcome key issues and how the results affect battery and vibrator design.
