Load driver circuit including load model parameter estimation

A method for driving a bad, the method comprising:

• providing a load current passing through the bad in accordance with at least one control signal;
• measuring, during operation of the load, at least one operation parameter of the load;
• and
• estimating, based on the at least one operation parameter and a parametric model that characterizes the load, one or more model parameters of the model.

A battery management circuit for controlling the charging or discharging process of a battery, the battery management circuit comprising:

• a power supply circuit operably coupled to the at least one battery cell and configured to provide a load current to the battery in order to charge or discharge the at least one battery cell;
• a measurement circuit coupled to the power supply circuit or the at least one battery cell and configured to measure, during charging or discharging of the load, at least one operation parameter of the at least one battery cell;
• and
• a signal processing circuit that receives the at least one operation parameter measured by the measurement circuit and configured to estimate, based on the at least one operation parameter and a parametric model that characterizes the at least one battery cell, one or more model parameters of the model.
