Title (EN) CHARGING CONTROL UNIT
(FR) UNITÉ DE COMMANDE DE CHARGEMENT
(JA) 充電制御装置
Abstract:
(EN)  A solar ECU (31) constituting a charging controller (30) activates by receiving all electric power generated directly from an onboard solar cell (21) without the use of a delay element for delaying a rise in starting voltage. The solar ECU (31) preferentially supplies the electric power generated by the onboard solar cell (21) to a sub-battery (19) and controls charging. Specifically, the solar ECU (31) preferentially supplies surplus electric power remaining after the solar ECU (31) has consumed power from the electric power generated by the onboard solar cell (21) to the sub-battery (19) when the charged amount of the sub-battery (19) is equal to or less than a prescribed charged amount. The solar ECU (31) thereby quickly activates and controls charging, whereby the electric power generated by the onboard solar cell (21), i.e., renewable energy, can be efficiently utilized without being needlessly wasted.
(FR)  L'invention concerne une ECU solaire (31) constituant un dispositif de commande de chargement (30) s'activant par la réception de toute l'énergie électrique générée directement à partir d'une cellule solaire embarquée (21) sans utiliser d'élément de retard pour retarder une augmentation de la tension de départ. L'ECU solaire (31) fournit préférentiellement l'énergie électrique générée par la cellule solaire embarquée (21) à une batterie secondaire (19) et commande le chargement. Spécifiquement, l'ECU solaire (31) fournit préférentiellement le surplus d'énergie électrique restant après que l'ECU solaire (31) a consommé l'énergie provenant de l'énergie électrique générée par la cellule solaire embarquée (21) à la batterie secondaire (19) lorsque la quantité chargée de la batterie secondaire (19) est égale ou inférieure à une quantité chargée prescrite. De ce fait, l'ECU solaire (31) active et commande rapidement le chargement, moyennant quoi l'énergie électrique générée par la cellule solaire embarquée (21), c'est-à-dire, de l'énergie renouvelable, peut être utilisée efficacement sans être inutilement gaspillée.
(JA)  充電コントローラ30を構成するソーラECU31は、車載太陽電池21から、起動電圧の立ち上がりを遅らせる遅れ要素を介することなく、直接的に発電された電力の総てを受けて起動する。そして、ソーラECU31は、車載太陽電池21によって発電された電力を優先的にサブバッテリ19に供給して充電制御する。具体的に、ソーラECU31は、サブバッテリ19の充電量が所定の充電量以下であるときには、車載太陽電池21によって発電された電力から自身の消費電力を減じた余剰電力をサブバッテリ19に優先的に供給する。これにより、ソーラECU31が速やかに起動して充電を制御することにより、車載太陽電池21によって発電された電力、言い換えれば、再生可能エネルギーを無駄に廃棄することなく有効に利用することができる。
