Estimation of battery aging using an interacting multiple model Kalman Filter
MetadataShow full item record
Battery management systems are responsible for ensuring that lithium-ions cells are operated within safe limits that will preserve the charge capacity and power delivery of a cell, while still meeting the demands of the system it is connected to. Not only must a battery management system seek to prevent premature aging, but as aging processes unavoidably occur, they impact the operational boundaries the battery management system seeks to enforce. While there are methods for identifying how aging has reduced the capacity or increased the resistance of a cell, there is no well-defined method for ...
