Accurate state of charge (SOC) estimation of a battery pack is more meaningful than that of a cell in practical applications. The existing methods are difficult to provide an accurate SOC of a battery pack under a wide range of temperature due to cell inconsistency. In this paper, a SOC estimation method for a series-parallel lithium-ion battery pack based on the …
We propose a battery management system with capacity equalization. The system can be used in arbitrarily series-parallel connected battery packs, and effectively manage batteries working in the charge or discharge mode. For the discharge mode, we develop a new method of battery capacity equalization, and determine the minimum number of …
The results show that the battery pack in parallel and then in series has a better performance on charge/discharge capacity, efficiency, and utilization rate of cells. Due to the low voltage and small capacity of a Li-ion battery cell, large numbers of cells are connected to construct a battery pack to satisfy the voltage and capacity requirement of …

A single cell is not sufficient for some devices. To achieve the desired voltage, the cells are connected in series to add the voltage of cells. To achieve the desired capacity, the cells are connected in parallel to get high capacity by adding ampere-hour (Ah). This combination of cells is called a battery. Sometimes battery…
Most of the battery pack modeling work in the literature considers very small battery packs consisting of either series only or parallel only connection [[26], [27] – 28, 30]. Some studies involve both series-parallel connection but have not been applied on commercial battery cells [ 23, 34 ].
