    Abstract

    Batteries are omnipresent, and with the uprise of the electrical vehicles will their use will grow even more. However, the batteries can deliver their required power for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in long lasting applications. Some detailed battery models that describe the degradation exist. However, these are complex models that require detailed knowledge. These models are in general computationally intensive, which does not make them well suited to be used in a wider context. A model better suited for this is the Kinetic Battery Model. In this paper, we this model would change due to battery degradation, by the results of our experimental degradation analysis. In our analysis we see that the degradation takes place in two phases. After the first phase of slow degradation, the battery suddenly starts to degrade rapidly.
