Customer ServiceHere''s a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. Use it to know the voltage, capacity, energy, and maximum discharge current of your battery packs, whether series- or parallel-connected.
Customer ServiceA crucial component of the battery pack is the Battery Management System (BMS). The BMS monitors the battery''s health, ensuring it operates safely and efficiently. It manages the charge and discharge cycles, controls temperature, and prevents overcharging. Without a BMS, the battery pack would be prone to failures and safety hazards. Part 4
Customer ServiceThe first important parameters are the voltage and capacity ratings of the battery. Every battery comes with a certain voltage and capacity rating. As briefly discussed earlier, there are cells inside each battery that form the voltage level, and that battery rated voltage is the nominal voltage at which the battery is supposed to operate.
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].
This battery pack calculator is particularly suited for those who build or repair devices that run on lithium-ion batteries, including DIY and electronics enthusiasts. It has a library of some of the most popular battery cell types, but you can also change the parameters to suit any type of battery.
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.
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.
