Power constraints: Performance requirements for standard HEVs generally focus on the power capabilities of the battery pack, rather than ca-pacity, and therefore battery packs for HEVs typ-ically do not require paralleling of cells. Perfor-mance requirements for EVs and PHEVs, on the other hand, are dominated by capacity needs.
To meet the specified performance re-quirements, the battery pack would require three cells in parallel and 96 cells in series, for a total of 288 cells. Two possible approaches for designing this bat-tery pack are shown in Fig. 1.
It is thus worth investigating if different configurations lead to different performance of the battery pack in presence of a mismatch in the cell characteristics. A simulation tool is developed in this work and applied to a battery pack consisting of standard 12 V modules connected with various serial/parallel topologies.
As can be seen, batteries can be connected in series, parallel, or both. In this case, each battery with "V" for voltage and "I" for current is connected either in series or parallel with other similar batteries. The total voltage and current depends on the wiring type.
For example, each parallel assembly connected in series within a battery pack requires a balancing circuit, and so the more parallel assemblies a pack has, the more cell balancing control signals are required in the battery management system.
Uneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells. Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections.

The configuration of battery packs frequently entails the parallel connection of cells followed by series interconnections, serving to meet power and energy requisites [4]. The performance of battery modules, particularly within the context of parallel cell configurations, assumes a pivotal role in dictating the aggregate functionality of the battery pack.
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.
In this case, the optimal reliability design scheme is the 5 × 5 parallel-series redundancy scheme with the design parameters x 1 = 40.50 mm, x 2 = 21.86 mm, x 3 = 0.49 mm, which can improve the cycle life of the battery pack with an initial configuration (3 × 5 parallel-series) from approximately 1989 to 2933 when taking 90% system reliability as the criterion.

Alexander et al. [26], [27] studied the simplified battery pack model with n-cells in parallel, and extended it to the complex series parallel topology of battery packs, solving the problem of modeling the inconsistency of large-scale serial and parallel connection battery pack. However, this model is not the ideal model of battery cells, based on the assumption that a …
Meanwhile, most publications aim at parallel battery packs, while series–parallel packs are less studied. Therefore, the purpose of this paper is to study the influences of connector resistance and MCP on the performance of the series–parallel battery pack and provide the guidelines for manufacturers to reduce the influences.

The boundary is drawn between level 2 (battery pack) and level 1 (battery system).
