Abstract:
(EN) The objective of the invention is to provide a battery pack reduced in size overall by eliminating current sensors. In order to solve the problem, the battery pack of the present invention has a configuration comprising: a battery group wherein a plurality of battery cells (lithium ion batteries 11, 12) are connected in series; a resistor (bus bar 20) connected in series to the battery group; voltage detection lines (voltage detection lines 101 to 104) disposed at the two ends of each of the battery cells (lithium ion batteries 11, 12) and the resistor (bus bar 20); and a battery controller connected to the voltage detection lines (voltage detection lines 101 to 104). One of the voltage detection lines (voltage detection lines 101 to 104) adjacent to one of the battery cells (lithium ion batteries 11, 12) has a terminal branching out to be connected to the battery controller.
(FR) L'objet de l'invention est de fournir un bloc-batterie dont la taille est réduite dans son ensemble par élimination de capteurs de courant. Afin de résoudre le problème, le bloc-batterie de la présente invention présente une configuration comprenant : un groupe de batteries dans lequel une pluralité de cellules de batterie (batteries au lithium-ion 11, 12) sont connectées en série ; une résistance (barre omnibus 20) connectée en série au groupe de batteries ; des lignes de détection de tension (lignes de détection de tension 101 à 104) disposées aux deux extrémités de chacune des cellules de batterie (batteries au lithium-ion 11, 12) et de la résistance (barre omnibus 20) ; et un contrôleur de batterie connecté aux lignes de détection de tension (lignes de détection de tension 101 à 104). L'une des lignes de détection de tension (lignes de détection de tension 101 à 104) adjacente à l'une des cellules de batterie (batteries au lithium-ion 11, 12) a une borne qui se ramifie pour être connectée au contrôleur de batterie.
(JA) 電流センサをなくし、全体的に小型化した電池パックを提供することを目的とする。 上記課題を解決するために。本発明の電池パックでは、複数の電池セル(リチウムイオン電池11、12)を直列に接続した電池群と、電池群に直列に接続された抵抗体(バスバー20)、電池セル(リチウムイオン電池11、12)及び抵抗体(バスバー20)の両端に配置された電圧検出線(電圧検出線101から104)と、電圧検出線(電圧検出線101から104)と接続される電池コントローラとを備え、電池セル(リチウムイオン電池11、12)に隣接した一つの電圧検出線(電圧検出線101から104)は、分岐して電池コントローラと接続される端子を有する構成とした。
