They found that the battery pack provided an additional 1250 cycles by maintaining a cylindrical graphite/LFP cell at a temperature of 37 °C and cycling it to the EOL voltage, followed by raising the ambient temperature by 1 °C to 38 °C.
Some studies indicate that the cycle life of the battery pack is much less than the single cell. Even the single cells have a cycle life more than 1000 cycles in group, without a balancing technology, the battery pack actual cycle life could be less than 200 cycles.
Up to 40 % of the components of a conventional battery pack can be saved by eliminating the module level . As a result, the costs for the passive materials in the battery decrease, and at the same time, the development effort can be reduced. The high degree of integration also reduces system complexity and minimizes the need for interfaces.
The dimensions of battery packs also require a design to space evaluation. The occupied volume of the pack should be suitable for the related car chassis. As previously mentioned in Section 1, CTP and CTC are two different strategies for packaging design. These approaches differ from the modular one.
ry pack offers the potential to achieve an even temperature distribution. This has a positive effect on a homogeneous degradation of the battery cells, wi h the result that all battery cells exhibit a simi-lar aging process . Once the use of the battery system in the vehicle is no longer efficient due to its aging, the entire pack can
directly into the battery pack itself as part of a cell-to-pack solution.In addition to the goal of developing performance-optimized battery systems, it is particularly important to consider the life cycle of the battery completely to enable a sustainable material cycle rang-ing from initial development, production, first-lif
