Abstract: A Method for Estimating State of Charge and State of Health of Battery and a System thereof The present invention relates to a method (200) and system (100) for estimating state of charge and state of health of a battery (10). A first vector (x) and a second vector (0) are initialised. The first vector (x) is estimated and updated by a first state-space filter based first equivalent circuit solver by assuming a fixed value of the second vector (0). the second vector (0) is estimated and updated based on an Electrochemical Model and then by a second state-space filter based second equivalent circuit solver. The updated values of the second vector (0) by the Electrochemical Model and the second state-space filter based equivalent circuit solver are merged. The state of charge is obtained from the updated value of the first vector (x), and the state of the health is obtained from the merged and updated value of the second vector (0).
