However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
Three typical benchmark methods are introduced and validated on a commercial Li-ion battery. The effect of SOC, C-rate and current direction on parameters variation are discussed. The performance of the three methods is validated on HPPC and three different cycles.
Battery pack vibration evaluation with parametric reduced order models The modules of the battery pack are assembled by bolts or welds to keep the cells packed together and the prestress due to joining can influence the dynamic response of the structure.
As lifetime still remains an issue for battery packs, it is a necessity to monitor the battery pack's state-of-health (SOH) on-board. Standard laboratory performance tests for health evaluation do not apply since operation interruptions and additional testing equipment are out of the question during ordinary EV usage.
Whenever you look at a new design of battery pack it is important to do some benchmarking of that design in the context of other battery packs. Any new pack will be measured against some key pack metrics and hopefully using a standard list of benchmarking data.
The dynamic and static research is determined by vehicle crash homologation, accreditation requirements, and transport legislation. The safety performance of the EV relies on the safety performance of the battery pack under different environments. Thereby, research on battery pack safety is considered seriously in recent years (Li et al., 2017).

A comprehensive review of the lithium-ion battery pack is presented to acknowledge the major factors that influence the structural performance and the electrical performance due to the working and environmental conditions.
A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.
