1. A method of estimating a maximum power of a battery, comprising the steps of:

  • measuring an internal resistance and a temperature of the battery and estimating its state of charge, if an estimation of the maximum power of the battery is requested; and

    reading a value of the maximum power of the battery, which corresponds to the measured temperature, the estimated state of charge, and the measured internal resistance, from a table in which the values of the internal resistance and the maximum power of the battery are mapped according to temperatures and states of charge.
