<P>PROBLEM TO BE SOLVED: To provide a battery simulator that simulates characteristics similar to those of an actual battery without measuring battery characteristics under various operation conditions. <P>SOLUTION: A simulation calculation part 23 stores a value obtained by integrating a battery charge/discharge capacity and a battery charging/discharging power capacity on the basis of measurement values of a battery input/output current and a battery input/output voltage, in a charge/discharge history storage part 25. The simulation calculation part calculates a correction value, in which a voltage change shown by an actual battery is simulated, from the values stored in the charge/discharge history storage part and battery characteristics. The simulation calculation part corrects a setting value, set by an output voltage setting part 21, with the correction value so as to control an output voltage of a power converter 10. Further, the simulation calculation part executes correction control in which changes in battery output voltage, changes in charge/discharge capacity, and changes or the like in charging/discharging efficiency are simulated according to a battery temperature, a charging state, and secular changes or the like that are set in a condition setting part 24. The simulation calculation part generates an alarm from an alarm generating part 28 when each value deviates from an operating range such as a charge/discharge upper limit value set in a battery. <P>COPYRIGHT: (C)2009,JPO&INPIT |
