The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
Battery pack voltage, using a high-voltage resistor divider. Shunt temperature, using a thermistor. Auxiliary measurements, such as the supply voltage, for diagnostic purposes. As demand for batteries to store energy continues to increase, the need for accurate battery pack current, voltage, and temperature measurements becomes even more important.
Cell balancing: The individual battery pack cells need to be monitored and balanced to redistribute charge between cells during charging and discharging cycles. Temperature monitoring: The individual cell temperatures and battery pack temperatures at several locations need measuring to ensure safe operation with maximum efficiency.
Increasing or decreasing the number of cells in parallel changes the total energy by 96 x 3.6V x 50Ah = 17,280Wh. As the pack size increases the rate at which it will be charged and discharged will increase. In order to manage and limit the maximum current the battery pack voltage will increase.
Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack. The magnitude of currents during charging and discharging modes could be drastically different by one or two orders of magnitude.
However, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
