Abstract
Official abstract text for this publication.
Provided are a battery state monitoring circuit and a battery device, in which, even when one secondary battery becomes an overcharged state or an overdischarged state and then a voltage detection circuit operates, power is not consumed in only the one secondary battery. The battery state monitoring circuit includes: a plurality of voltage detection circuits which are provided for a plurality of secondary batteries, respectively, for detecting voltages of the plurality of secondary batteries; and a current bypass circuit provided in each of the plurality of voltage detection circuits, for allowing an operation current of the each of the plurality of voltage detection circuits to flow into a ground terminal. Therefore, when only one secondary battery becomes an overcharged state or an overdischarged state, the battery device operates so that the power of all the secondary batteries is consumed to prevent voltages between the secondary batteries from being unbalanced.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery state monitoring circuit for detecting and controlling states of a plurality of secondary batteries, the monitoring circuit comprising: a plurality of voltage detection circuits for each of the plurality of secondary batteries, respectively, each detecting a voltage of a corresponding one of the plurality of secondary batteries; and a current bypass circuit in each of the plurality of voltage detection circuits, for allowing an operation current…
