intelligence algorithm to the health status of electric car battery pack. This is the new evaluating method for
the battery health. The team published an article on the Journal of Power Supply to introduce their research work.
through this way can obtain the dynamic response of battery pack and improve its safe
reliability.However,the discharge and charge performance of battery and the working environment of battery pack are
different, and these make evaluating the health status of battery pack being difficult.
contains all the information of cell, like battery capacity, the relevance between the state of charge and the open-
circuit voltage, and the inconsistency of battery.
experimental result, they used particle filter to predict the battery’s state of charge and open-circuit voltage, to
avoid noise and drift current in the terminal voltage test. They also adopted recursive least square method to improve
