Guide How to measure voltage of multiple batteries connected in string
For example for the above circuit the measured voltage across battery-1 is 48v and battery-2 is 36v. Negating 48v-36v=12v gives us battery-1 voltage. Similarly if battery-3 is at 23v. Than 36v-23v gives 13v. So battery-2 is supplying 13 volts in series string array. Other batteries voltages can be calculated with same method.

Because zero further copies are allowed to complete the match, when there is no repeating group, the whole string is returned, which is correct behaviour. Once you have this string, you don''t actually need to "divide" the string up, you just need n copies of it. However as a convenience you can split the sting equal parts by splitting on the

6 Frequently Asked Questions about “How to divide the battery pack into strings”
How are cells arranged in a battery pack?
Given a number of cells in a battery pack (such as 100 cells), they can be arranged as sets of cells directly in parallel, which are then connected in series (such as a 2P50S battery), or as strings of cells in series, which are then connected in parallel (such as 50S2P).
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.
Can you add a battery to a string?
Adding cells in a string increases the voltage; the capacity remains the same. If you need an odd voltage of, say, 9.50 volts, connect five lead acid, eight NiMH or NiCd, or three Li-ion in series. The end battery voltage does not need to be exact as long as it is higher than what the device specifies. A 12V supply might work in lieu of 9.50V.
How do I wire a battery pack?
There is no correct/wrong order where you can start wiring the pack. The first cell on the daisy chain will be the first blue bar or cell #1 on the screen. The last cell on the network chain will be shown as the last blue bar on the screen. Batteries are normally wired starting from cell #1, being the most negative cell on the pack.
How do you calculate the number of cells in a battery pack?
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 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 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 to the energy content of a string E bs . The number of strings must be an integer. Therefore, the result of the calculation is rounded to the higher integer.
