Battery Operation Cycle Management for Electric Vehicles with Battery Switching Technology

In this paper the impact that the implementation of electric vehicles (EVs) battery switching technology has on the Li-ion batteries lifetime, has been explored under possible real-life operating conditions. A generic semi-empirical battery degradation model, which is representative for Li-ion batteries used in EVs, was designed based on battery test measurements. Based on this model, the principles of the battery operation cycle management algorithm were defined, through simulating different scenarios. The suggested algorithm, whose purpose is to assign batteries to EVs optimizing the battery lifetime, can be directly used in battery switching stations.
