Electric Vehicle (EV) and Hybrid Electric Vehicles (HEV) is one solution in reducing tailpipe emission. However the most expensive part in the EV and HEV is the energy storage system. Increasing the lifetime of the battery will improve the cost effectiveness of all vehicles using this technology.
This project is a part of a larger project in a cooperation between Chalmers, Volvo Cars Corporation, Uppsala University and ABB. The goal is to give a better understanding and prediction of the aging in Li-ion batteries. The focus in this sub project is to characterize the main aging processes in Li-ion batteries. To mathematically describe them in a model predicting aging and lifetime of the battery. Further to use the new insights in deriving how the batteries are best utilized in the electrified vehicles for longest possible lifetime, with lowest possible impact on performance reduction.
