Title (EN) VOLTAGE DETECTING CIRCUIT
(FR) CIRCUIT DE DÉTECTION DE TENSION
(JA) 電圧検出回路
Abstract:
(EN) Provided is a voltage detecting circuit that measures a plurality of cell voltages of a battery pack configured by connecting a plurality of cells in series. The voltage detecting circuit is provided with: a plurality of input terminals respectively connected to the electrodes of the plurality of cells via a plurality of voltage detecting lines; a multiplexer for periodically selecting the voltages of a plurality of cells in a group constituted by the plurality of cells connected in series, and outputting the resulting voltage; an AD converter for performing AD conversion on the output voltage from the multiplexer to output digital data of the output voltage; and a control circuit for controlling selection timing for the multiplexer and timing of the AD conversion. The control circuit switches time intervals at which the multiplexer selects each cell to change the period of the AD conversion.
(FR) L'invention concerne un circuit de détection de tension qui mesure une pluralité de tensions de cellule d'un bloc-batterie conçu par connexion d'une pluralité de cellules en série. Le circuit de détection de tension comprend : une pluralité de bornes d'entrée connectées respectivement aux électrodes de la pluralité de cellules par l'intermédiaire d'une pluralité de lignes de détection de tension; un multiplexeur permettant de sélectionner périodiquement les tensions d'une pluralité de cellules dans un groupe constitué par la pluralité de cellules connectées en série, et d'émettre en sortie la tension résultante; un convertisseur A/N permettant d'effectuer une conversion A/N sur la tension de sortie provenant du multiplexeur afin d'émettre en sortie des données numériques de la tension de sortie; et un circuit de commande permettant de commander la synchronisation de sélection pour le multiplexeur et la synchronisation de la conversion A/N. Le circuit de commande commute des intervalles de temps auxquels le multiplexeur sélectionne chaque cellule afin de changer la période de la conversion A/N.
(JA) 電圧検出回路は、複数のセルを直列に接続して構成される組電池の複数のセル電圧を測定する。電圧検出回路は、複数の電圧検出線を介してそれぞれ複数のセルの各電極に接続される複数の入力端子と、複数の直列セルをグループとして、周期的にグループ内の複数セルの電圧を選択して出力するマルチプレクサと、マルチプレクサからの出力電圧のAD変換を行って出力電圧のデジタルデータを出力するAD変換器と、マルチプレクサの選択タイミングおよびAD変換のタイミングを制御する制御回路を備え、制御回路は、マルチプレクサが各セルを選択する時間間隔を切り替えることでAD変換の周期を変化させる。
