Material selection and assembly method as well as component design are very important to determine the cost-effectiveness of battery modules and battery packs. Therefore, this work presents Decision Matrix, which can aid in the decision-making process of component materials and assembly methods for a battery module design and a battery pack design.
Conclusions This study developed a model-based methodology for use in the design of battery packs for automotive applications. This methodology is based on a multi-domain simulation approach to allow electric, thermal and geometric evaluations of different battery pack configurations, with particular reference to Li-NMC technology.
The battery pack numerical model The BP model was developed on the basis of a Two-cell Interaction model. In particular, the model simulates the behavior of every single cell in the BP and the environment that surrounds them.
An optimal battery packing design can maintain the battery cell temperature at the most favorable range, i.e., 25–40 °C, with a temperature difference in each battery cell of 5 °C at the maximum, which is considered the best working temperature. The design must also consider environmental temperature and humidity effects.
Arora et al. show that for commercial cars, relative battery cell movement and displacement are commonly used as the failure criteria of the packing. The source of movement or displacement can come from a thermal event, vehicle vibration, or impact loading when an accident happens .
The reconstruction of more robust battery packing is also one of the practical solutions to handle battery packing design problems. Arora et al. show that for commercial cars, relative battery cell movement and displacement are commonly used as the failure criteria of the packing.

Battery pack selection for self-launching glider
The price and weight for a LiPo pack which can launch the AC-5M to 300m (~1000'') is $500 and 3kg. The same pack in LiPo is going to be $3-4k and 12-15kg. The Li-ion pack will be good for another 50 minutes of cruise flight, but that''s not the standard mission profile and so that extra battery time is typically unused dead weight.
