Abstract
(EN)
A battery pack is disclosed. A battery pack according to an embodiment of the present invention comprises: a first battery contactor and a second battery contactor each of which has one end electrically connected to a positive electrode terminal and a negative electrode terminal of a battery, respectively; a first charging contactor and a second charging contactor each of which has one end electrically connected to the other end of the first battery contactor and the other end of the second battery contactor, respectively; a first power connector which is connected to a second power connector of a charger having a first output terminal and a second output terminal; and a control unit which, if the second power connector is connected to the first power connector and a charging voltage is not applied between the first output terminal and the second output terminal from the power source of the charger, is for controlling the first charging contactor and/or the second charging contactor to be in a turn-on state or a turn-off state and diagnosing whether or not the first charging contactor or the second charging contactor is malfunctioning.

La présente invention concerne un bloc-batterie. Un bloc-batterie selon un mode de réalisation de l'invention comprend : un premier contacteur de batterie et un second contacteur de batterie dont chacun a une première extrémité connectée électriquement à une borne d'électrode positive et à une borne d'électrode négative d'une batterie, respectivement; un premier contacteur de charge et un second contacteur de charge dont chacun a une première extrémité connectée électriquement à l'autre extrémité du premier contacteur de batterie et à l'autre extrémité du second contacteur de batterie, respectivement; un premier connecteur d'alimentation qui est connecté à un second connecteur d'alimentation d'un chargeur ayant une première borne de sortie et une seconde borne de sortie; et une unité de commande qui, si le second connecteur d'alimentation est connecté au premier connecteur d'alimentation et une tension de charge n'est pas appliquée entre la première borne de sortie et la seconde borne de sortie de la source d'alimentation du chargeur, est conçue pour commander le premier contacteur de charge et/ou le second contacteur de charge pour qu'ils soient dans un état sous tension ou un état hors tension et pour diagnostiquer si oui ou non le premier contacteur de charge ou le second contacteur de charge est défaillant.
