Abstract

The present invention relates to a method and a system (200) for determining a parameter map (502) used for estimating an operation condition for an energy storage device (102) which may be an energy storage device, the method comprising updating the parameter map. When updating the parameter map, a correlation model is implemented taking into account aging behavior of the energy storage device. The model comprises correlation between different parts of the parameter map which enables updating the parameter map at parts which is presently not at a current operating point. Based on the parameter map, an operation condition of the energy storage device may be determined.
