HBK LDS Vibration Test Systems for Battery Testing

The de-carbonization of some sectors of the Australian society and economy continues. So does the electrification of various products, including cars, energy storage, buses, some kitchen stoves, the first boats, etc. Many of these products require batteries.

In the mobility sector, electric vehicle (EV) battery systems typically represent 80% of the cost of the powertrain. The goal of testing is to identify and correct any imperfections in design or manufacturing, validate product release as early as possible, and bring new products to market swiftly. Since authorities worldwide classify lithium-ion batteries as “dangerous goods”, they are also subject to rigorous regulatory test standards. Several regulations, such as ECE R100 and ISO12405, have been developed to standardize the testing procedures of batteries and their subsystems. They all have one thing in common: before a battery cell, module or pack can be transported, it must be tested.

EV Battery Testing inflicts multiple stresses on the cell, module, pack, or sub-system simultaneously. Shakers apply vibration or shock loads. At the same time, environmental chambers add temperature and humidity factors. Combining these mechanical and environmental factors with electrical tests that simulate power cycling, enables engineers to observe and measure the cumulative effects on battery performance and durability.

The ideal configuration for EV Battery vibration and shock testing begins with a reliable and robust high-force electrodynamic shaker, powered by an energy-efficient amplifier system. A slip-table equipped with pedestals minimises moving masses, while maximising the payload. Compatibility of the platform with climatic chambers from leading international manufacturers enables test engineers to add the environmental conditions required for effective EV battery testing.

NVMS and HBK offer a large range of shakers, amplifiers, accelerometers, controllers, and support services.

The HBK LDS shakers below are some of the ones often used for EV battery testing.
