Internal Short Circuit Detection for Parallel-Connected Battery …
Reliable and timely detection of an internal short circuit (ISC) in lithium-ion batteries is important to ensure safe and efficient operation. This paper investigates ISC detection of parallel-connected battery cells by considering cell non-uniformity and sensor limitation (i.e., no independent current sensors for individual cells in a parallel string). To …

Numerical simulation for the discharge behaviors of batteries in …
But when it is connected in parallel with a small capacity battery of high C-rate performance, the battery pack does not fail due to this large-capacity battery. The small capacity battery in the battery pack during the initial discharge process shares a large amount of current, so to ease out the share of the large capacity battery.
All About Drivetrains | Union of Concerned Scientists
This system incurs higher costs than a pure parallel hybrid since it requires a generator, a larger battery pack, and more computing power to control the dual system. Yet its efficiencies mean that the series/parallel drivetrain can perform better—and use less fuel—than either the series or parallel systems alone.

Ultimate Power: Lithium-Ion Batteries In Series
The common notation for battery packs in parallel or series is XsYp – as in, the battery consists of X cell "stages" in series, where each stage consists of Y cells in parallel. So, putting ...
Resolving Kirchhoff''s Laws for Parallel Li-Ion Battery Pack State ...
A state-space model for Li-ion battery packs with parallel-connected cells is introduced. The key feature of the model is an explicit solution to Kirchhoff''s laws for parallel-connected packs, which expresses the branch currents directly in terms of the model''s states, applied current, and cell resistances. This avoids the need to solve these …
Quantifying cell-to-cell variations of a parallel battery module for ...
1. Introduction. The impact of parallel strings of battery cells on pack performance has been neglected for many years and only recently identified as one of the critical areas to be considered [1].Due to the common voltage of the parallel cells, most studies assume that all parallel cells undergo similar currents.
Management of imbalances in parallel-connected lithium-ion battery packs
As shown in Table 2, the first two experimental case studies investigated the evolution of current distribution during the discharge process using different discharge C-rates (scenarios 1–4) case study 1, there were four charge/discharge cycles. In each cycle, three LiFePO 4 cells were fully charged individually to reduce the OCV difference …
