The size and mass of the high voltage battery are very important parameter to consider when designing a battery electric vehicle (BEV).
How do you calculate battery pack voltage?
The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
How to calculate battery pack capacity?
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 [-].
How do you calculate the total number of strings in a battery pack?
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 number of strings must be an integer. Therefore, the result of the calculation is rounded to the higher integer.
How to calculate number of battery cells connected in Series NCS -?
The number of battery cells connected in series N cs [-] in a string is calculated by dividing the nominal battery pack voltage U bp [V] to the voltage of each battery cell U bc [V]. The number of strings must be an integer. Therefore, the result of the calculation is rounded to the higher integer.
