Battery Dual Extended Kalman Filter State of Charge and Health Estimation Strategy for Traction Applications

The growing market of electrified vehicles requires efforts from car manufacturers to build robust systems to deal with all types of situations their products will face in customers’ hands. A major system of electrified vehicles is the energy storage unit. The complexity of batteries lies in their nonlinear behaviour that is highly dependent on external factors such as temperature and load dynamics. To handle these conditions, the battery …
