Due to the constraint of loading from underneath the eBus, a “tooth” mounting system was proposed as the best strategy to increase package space and provide secure attachment to the vehicle. This mounting system is similar to bus fuel tank mounting, which is designed to hold a similar mass with full fuel tank.

By definition, a Battery Energy Storage Systems (BESS) is a type of energy storage solution, a collection of large batteries within a container, that can store and discharge electrical energy
The chassis can come with or without integrated fan trays or with redundant push-pull cooling. EMC versions are also standard. There are several legacy architectures that utilize Eurocard
A reliable battery packaging design should address issues relating to thermal stability, vibration isolation and impact resistance at micro- as well as macro-level. Further, it should minimise
Mobile energy storage technologies for boosting carbon neutrality Thus, the packaging and struc-tural innovation of a battery pack system are also signi ficant to simplify the bat-tery,
The analysis demonstrates the use of a multifunctional (damage tolerant and energy storage capable) battery system to ensure battery safety and aid in the energy absorption in a crash overall.
Systems are improving. However, specific energy is improving more than energy density. More room for improvements is thus to be gained in packaging optimization and could be a next step for further battery system development.

Robust mechanical design and battery packaging can provide greater degree of protection against all of these. This chapter discusses design elements like thermal barrier and gas exhaust mechanism that can be integrated into battery packaging to mitigate the high safety risks associated with failure of an electric vehicle (EV) battery pack.
Compactness of packaging design also has an appreciable impact on thermal performance of the battery pack. Research shows that increasing the cell-to-cell spacing for a battery pack from 1 to 10 mm can lead to a loss of approximately 1 °C in the steady-state cell core temperature, for all the three physical formats .
A robust and strategic battery packaging design should also address these issues, including thermal runaway, vibration isolation, and crash safety at the cell and pack level. Therefore, battery safety needs to be evaluated using a multi-disciplinary approach.
The lightweight battery pack enclosure design is desirable for maintaining a long-range and having good safety. Xiong et al. studied a novel procedure that significantly reduced the weight of the battery pack by improving its crashworthiness.
In this chapter, mechanical design elements affecting safety and reliability of EV battery packaging are discussed. Forces like mechanical vibration, impact energy and ambient temperature variations interact with the battery pack through different interfaces. These interactions need to be controlled for safe and reliable operation of battery pack.
Systems are improving. However, specific energy is improving more than energy density. More room for improvements is thus to be gained in packaging optimization and could be a next step for further battery system development. Other aspects looked at are cell types and sizes. There, a trend to larger and prismatic cells could be identified.
