How cell balancing is used in a battery pack?
There are different techniques of cell balancing have been presented for the battery pack. It is classified as passive and active cell balancing methods based on cell voltage and state of charge (SOC). The passive equivalent to the lowest level cell SOC. The active cell balancing transferring will be equal.
How to increase the life of a battery pack?
One of the most significant factors is cell imbalance which varies each cell voltage in the battery pack overtime and hence decreases battery capacity rapidly. So as to increase the lifetime of the battery pack, the battery cells should be frequently equalized to keeps up the difference between the cells as small as possible.
Why do lithium ion cells have a low battery capacity?
Furthermore, initial variations of the capacity and impedance of state of the art lithium-ion cells play a rather minor role in the utilization of a battery pack, due to a decrease of the relative variance of cell blocks with cells connected in parallel.
What is a Li-ion battery pack?
The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system. Due to manufacturing irregularity and different operating conditions, each serially connected cell in the battery pack may get unequal voltage or state of charge (SoC).
Why are lithium-ion battery cells connected in series?
Many lithium-ion battery cells are usually connected in series to meet the voltage requirements. The voltages of the entire series-connected battery cells in a battery pack should be equal. However, such result is impossible due to some unavoidable reasons in real life.
How to improve battery performance based on battery States?
However, online adjustment of these parameters based on the battery states is required in order to improve the performance. For example, the amount of charge transfer during the cell equalization can be controlled by using the battery SOC value in real-time.
