One of the biggest challenges in electric transportation is storing electrical energy for use in desired times and desired amounts. Batteries are mostly considered because of their high energy density compared to their counterparts and also their ability to get charged providing regenerative braking capability. The electrochemical nature of batteries has a highly nonlinear behavior and dependent on many factors such as state of charge, state of health, runtime, temperature, aging, load profile, and charging algorithm. A very important concern is related to storage, because in order to have a given amount of energy for a reasonable All Electric Range (AER), tens or hundreds of cells should be connected in series and parallel for the desirable voltage and current ratings of the battery pack. This causes the nonlinear behavior of cells to be more prominent. Furthermore, there are some phenomena that are observed only in battery packs and not in single cells, such as thermal unbalance among the cells in pack.
