» Electrical » Battery Energy Density Calculator The Battery Energy Density Calculator provides crucial metrics for battery manufacturers, designers, and end-users by calculating the gravimetric (Wh/kg) and volumetric (Wh/L) energy density of batteries.
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].
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 [-].
Higher energy densities mean a battery can store more energy relative to its size and weight, which is crucial for enhancing the performance and portability of devices. Can the energy density of a battery change over time?
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.
Fill in the number of cells in series and parallel, the capacity of a single cell in mAh, and the voltage of a single cell in volts (default is 3.7V). Press the “Calculate” button to get the total voltage, capacity, and energy of the battery pack. This calculator assumes that all cells have identical capacity and voltage.
