1. A battery management system comprising:

  • voltage and current measuring means for measuring a voltage and a current of said battery;

    calculation means for calculating respective values of maximum available charge and discharge powers or maximum available charge and discharge currents of said battery based on the voltage and the current of said battery measured by said voltage and current measuring means; and

    limiter means for limiting the values of the maximum available charge or discharge powers or the maximum available charge or discharge currents, which are calculated by said calculation means, to be reduced when the voltage of said battery measured by said voltage and current measuring means is near an upper limit voltage or a lower limit voltage.
