Abstract
(EN)
A charging apparatus (200) which transforms electricity from an external power supply (260) to an electric charge of an electricity storage device (110) transforms AC electricity of power lines (ACL1, ACL2) to an electric charge of an auxiliary battery (180). A CHR (240) either forms or interrupts a path between the charging apparatus (200) and the electricity storage device (110). A DC/DC converter (230) converts DC electricity on a power line (PL2) which is connected to a smoothing capacitor (C2) to an electric charge of the auxiliary battery (180) and outputs same to a power line (PL3). When discharging with the CHR (240) switched off, an ECU (300) discharges the smoothing capacitors (C1, C2) by operating the DC/DC converter (230) and charging the auxiliary battery (180) even when the voltage (Vo) of the power line (PL2) is lower than an adjudication voltage.
(FR)
Un appareil de charge (200) qui transforme l'électricité provenant d'une alimentation externe (260) en charge électrique d'un dispositif de stockage d'électricité (110) transforme l'électricité CA de lignes d'alimentation (ACL1, ACL2) en une charge électrique d'une batterie auxiliaire (180). Un CHR (240) forme ou interrompt un chemin entre l'appareil de charge (200) et le dispositif de stockage d'électricité (110). Un convertisseur CC/CC (230) convertit l'électricité CC sur une ligne d'alimentation (PL2) qui est reliée à un condensateur de lissage (C2) en une charge électrique de la batterie auxiliaire (180) et sort celle-ci sur une ligne d'alimentation (PL3). Lors de la décharge quand le CHR (240) est désactivé, une ECU (300) décharge les condensateurs de lissage (C1, C2) par l'actionnement du convertisseur CC/CC (230) et la charge de la batterie auxiliaire (180) même lorsque la tension (Vo) de la ligne d'alimentation (PL2) est inférieure à une tension de décision.
(JA)
 外部電源(260)からの電力を蓄電装置(110)の充電電力に変換する充電器(200)は、電力線(ACL1,ACL2)の交流電力を補機バッテリ(180)の充電電力に変換する。CHR(240)は、充電器(200)および蓄電装置(110)の間の経路を形成あるいは遮断する。DC/DCコンバータ(230)は、平滑コンデンサ(C2)と接続された電力線(PL2)上の直流電力を、補機バッテリ(180)の充電電力に変換して電力線(PL3)に出力する。ECU(300)は、電力線(PL2)の電圧(Vo)が判定電圧より低い場合であっても、CHR(240)がオフされているディスチャージ時には、DC/DCコンバータ(230)を動作させて補機バッテリ(180)を充電することによって、平滑コンデンサ(C1,C2)を放電する。
