How to calculate the heat dissipated by a battery pack?

Heat out of pack is a simple P=RI^2 equation. You know the current out of each cell, and you know (or should be able to find out) the internal resistance of each cell. So you know the power, which then just needs to be removed for the pack. Ah is not the unit of current but the unit of charge (current multiplied by time).

6 FAQs about [Battery pack discharge loss calculation]

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 [-].

What is a battery pack calculator?

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.

How do you calculate the energy content of a battery pack?

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].

How do you calculate battery pack current?

If the current through each battery cell is I cell = 2 A and there are 3 cells connected in parallel (N p = 3), the battery pack current is calculated as: I pack = N p · I cell = 3 · 2 = 6 A In parallel circuits, the voltage across each cell is the same and equal to the voltage of the power source.

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 do you calculate the efficiency of a battery pack?

The power loss of the battery pack is calculated as: P loss = R pack · I pack2 = 0.09 · 4 2 = 1.44 W Based on the power losses and power output, we can calculate the efficiency of the battery pack as: η pack = (1 – P loss /P pack) · 100 = (1 – 1.44/43.4) · 100 = 96.682 %
