Abstract
A residual quantity measuring device is provided. The residual quantity measuring device includes a Hall element that is inserted into a path of a current flowing in a battery unit and outputs an output voltage associated with the current; and a Coulomb counter configured to be supplied with the output voltage of the Hall element via a voltage conversion circuit and to detect a total quantity of a current flowing into the battery unit and a current flowing out of the battery unit.
