Abstract
Official abstract text for this publication.
A battery remaining amount detection unit includes: a voltage measurement section configured to measure a voltage of a battery; an open-circuit voltage calculation section configured to calculate an estimated open-circuit voltage; and a remaining amount detection section configured to detect a remaining amount of the battery from the estimated open-circuit voltage, in which the open-circuit voltage calculation section is configured to calculate a first voltage change amount as a voltage change amount from a no-load voltage when no load is applied to the battery and a closed-circuit voltage when a load is applied to the battery, and the open-circuit calculation section is configured to calculate the estimated open-circuit voltage based on the closed-circuit voltage of the battery and the first voltage change amount.
