ABSTRACT:
A power control system for obtaining the maximum electric power from a battery power source. The system functions to vary an output voltage of the battery power source to obtain (m) power values from at least (m) voltage signals from a voltage detector and at least (m) current signals from a current detector which were sampled at desired intervals. A function is used which approximates the relations between the (m) voltage values and (m) power values. A voltage is calculated at which a power is set to a maximum value from the function and the (m) voltage and power values. The power is set at such a voltage into an output power set value and the output power of the battery power source is controlled.
