The main target of the battery pack design is to reduce the costs of the individual components and increase the energy density on a system level without affecting the safety and lifetime. 10.1. Introduction
As for PHEVs and especially BEVs the battery pack accounts for the biggest part of the weight of the whole vehicle, the battery housing is designed in strong interaction with the design of the body of the car.
Depending on the location of the battery pack in the specific vehicle application, the casing is designed to withstand occurring crash loads. Hence the required crash performance of the battery pack substantially influences the design and especially the weight of the housing and the whole system.
The pack is enclosed in a battery pack protective housing that shields the cells and the BMS from external influences such as water, dust, and physical damage. The enclosure is designed to ensure durability within the available space. Typical design for battery housing (image source: Mubea)
As hinted at above, another benefit of a higher pack voltage is a reduction in the size of the wires needed for the charging cable for a given power output (i.e. charging rate).
This depends on the chosen chemistry and configuration. Evaluate Combinations: Designers explore different battery pack combinations to find the most suitable arrangement that meets the performance requirements while optimizing space and weight.
