電池の残容量検出方法

Document Type and Number:

Japanese Patent JP4514541

Kind Code:

B2

Abstract:

To accurately detect residual capacity when the temperature of a battery is low.

This residual capacity detection method is a method for correcting a residual capacity of a battery detected from an integration value of its discharge current to a low capacity previously set for the residual capacity when a battery voltage falls to a set voltage. If the temperature of the battery is lower than a lowest temperature and the residual capacity of the battery is larger than a determination capacity when the battery voltage falls to the set voltage, the residual capacity is not corrected to the low capacity.
