6 FAQs about [Four-level battery pack power calculation]

How do you calculate a high voltage battery pack?

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.

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 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].

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.

What determines the operating voltage of a battery pack?

The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.

How much energy does a battery pack use?

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.
