Inconsistencies that are associated with parallel-connected cells used in electric vehicles\ninduce varied states of charge (SOCs) in each cell. Thus, loop current in the battery pack is inevitable,\nand this reduces overall capacity, energy utilization rate, and pack lifetime. However, no method\nis available to address loop current. To reduce loop current and the resulting battery inconsistency,\na parallel-connected cell pack (PCCP) model that considers thermal effects is established, and a novel\nSimscape model that is based on PCCP is successfully constructed. Furthermore, the strategy of\nparallel-connected cell energy management (PCCEM) is proposed to utilize fuzzy logic control (FLC)\nstrategy, which automatically adjusts the number of cells in a circuit in accordance with the load\ndemand, and turns on the first N switches in the corresponding SOC order. The New European\nDriving Cycle (NEDC) driving cycle simulation shows that the PCCEM strategy considerably\nreduces loop current and improves the consistency of battery performance and the utilization rate of\nbattery power.
