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 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 [-].
The energy content of a string E bs [Wh] is equal with the product between the number of battery cells connected in series N cs [-] and the energy of a battery cell E bc [Wh]. The total number of strings of the battery pack N sb [-] is calculated by dividing the battery pack total energy E bp [Wh] to the energy content of a string E bs [Wh].
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 required battery pack total energy E bp [Wh] is calculated as the product between the average energy consumption E avg [Wh/km] and vehicle range D v [km]. For this example we’ll design the high voltage battery pack for a vehicle range of 250 km. The following calculations are going to be performed for each cell type.
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.
