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.
The battery pack will be designed for an average energy consumption of 161.7451 Wh/km. All high voltage battery packs are made up from battery cells arranged in strings and modules. A battery cell can be regarded as the smallest division of the voltage. Individual battery cells may be grouped in parallel and / or series as modules.
The battery pack capacity C bp [Ah] is calculated as the product between the number of strings N sb [-] and the capacity of the battery cell C bc [Ah]. The total number of cells of the battery pack N cb [-] is calculated as the product between the number of strings N sb [-] and the number of cells in a string N cs [-].
Variation in cell capacity and resistance along with number of cells in series and parallel will determine the actual energy capacity of any pack. Temperature management of the cells and variations across the pack will influence power and energy.
Resistance of the cells, connections, busbars and HV distribution system will determine the power and energy capability of the pack. Variation in cell capacity and resistance along with number of cells in series and parallel will determine the actual energy capacity of any pack.
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.
