Abstract
Official abstract text for this publication.
A voltage measurement circuit, which can reduce a withstand voltage of each of voltage dividing resistors for voltage measurement, with respect to a surge voltage generated at the time of turning-on of a dark-current reduction relay, thereby enabling cost reduction, is provided. The voltage measurement circuit includes: a high-voltage input terminal; a plurality of voltage dividing resistors which divide a high voltage; a voltage measuring part which measures a voltage reduced to a low voltage by the plurality of voltage dividing resistors; and a dark current reduction relay which is connected in series between adjacent ones of the plurality of voltage dividing resistors.
First claim
Opening claim text (preview).
1 . A voltage measurement circuit comprising: a high-voltage input terminal; a plurality of voltage dividing resistors which divide a high voltage inputted from the high-voltage input terminal; a voltage measuring part which measures a voltage reduced to a low voltage by the plurality of voltage dividing resistors; and a dark current reduction switch circuit which is connected in series between adjacent ones of the plurality of voltage dividing resistors. 2 . The voltage measurement circuit according to claim 1 , wherein the dark current reduction switch circuit is connected at a center or a portion close to the center of the plurality of voltage dividing resistors. 3 . The voltage measurement circuit according to claim 1 , wherein the high-voltage input terminal is connected to a battery of an electric car or a hybrid car.
