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 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 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 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 are batteries classified?

Batteries can be classified according to their chemistry or specific electrochemical composition, which heavily dictates the reactions that will occur within the cells to convert chemical to electrical energy. Battery chemistry tells the electrode and electrolyte materials to be used for the battery construction.

Understanding Charge-Discharge Curves of Li-ion Cells

Lithium-ion cells can charge between 0°C and 60°C and can discharge between -20°C and 60°C. A standard operating temperature of 25±2°C during charge and discharge allows for the performance of the cell as per its datasheet.. Cells discharging at a temperature lower than 25°C deliver lower voltage and lower capacity resulting in lower energy delivered.
