System for determining battery conditions |
摘要 |
Detected values of a voltage and a current of a battery which are supplied from a voltage and current detector are stored in a memory at a plurality of times while the battery is being discharged. A regression line calculator determines an internal resistance and an open-circuit voltage (non-load voltage or electromotive force) of the battery based on the detected values stored in the memory. Even when the battery is in use with the voltage and the current frequency varying while it is being discharged, a memory effect on the battery can be determined from a reduction in the open-circuit voltage and a deterioration of the battery can be determined from an increase in the internal resistance.
