Abstract
(EN)
In order to satisfy both ensuring of the safety of an electric vehicle and ensuring of the convenience of users, in this power supply system (10) mounted on an electric vehicle (1), a voltage measurement unit (13) measures the voltage of each of a plurality of cells (E1-En). A current measurement unit (15) measures the current flowing through the plurality of cells (E1-En). A temperature measurement unit (14) measures the temperatures of the plurality of cells (E1-En). A control unit (16) determines a current limit value specifying the upper limit of current for suppressing the degradation of the cells and ensuring safety on the basis of the voltage of each cell measured by the voltage measurement unit (13), the current measured by the current measurement unit (15), and the temperature measured by the temperature measurement unit (14), and notifies an upper level control unit in the electric vehicle (1) of the determined current limit value.

Pour satisfaire à la fois l'exigence de garantie de la sécurité d'un véhicule électrique et de garantie du confort des utilisateurs dans le présent système d'alimentation électrique (10) monté sur un véhicule électrique (1), une unité de mesure de tension (13) mesure la tension de chaque cellule d'une pluralité de cellules (E1-En). Une unité de mesure de courant (15) mesure le courant circulant à travers la pluralité de cellules (E1-En). Une unité de mesure de température (14) mesure les températures de la pluralité de cellules (E1-En). Une unité de commande (16) détermine une valeur limite de courant spécifiant la limite supérieure de courant pour supprimer la dégradation des cellules et assurer la sécurité en fonction de la tension de chaque cellule mesurée par l'unité de mesure de tension (13), du courant mesuré par l'unité de mesure de courant (15), et de la température mesurée par l'unité de mesure de température (14), et indique à une unité de commande de niveau supérieur présente dans le véhicule électrique (1) la valeur limite de courant déterminée.
