Title:
METHOD AND APPARATUS FOR SOFT-SENSOR CHARACTERIZATION OF BATTERIES
Document Type and Number:
WIPO Patent Application WO2003049211
Kind Code:
A3
Abstract:
A method and apparatus are disclosed for simulating the operation of a rechargeable battery. There is obtained (503, 553) a value for at least one parameter that describes an internal state of the battery. Said obtained value is used for calculating (504, 505, 554, 555) a prediction value for a characteristic of the battery that is observable outside the battery. These steps are repeated a multitude of times in order to simulate the operation of the battery over a certain period of time. A difference is detected (507, 556) between a calculated prediction value and a known value of a corresponding characteristic in a corresponding situation. The obtained value of said at least one parameter is corrected (507, 558) before a further prediction value calculating step by an amount that is proportional to said detected difference.
