Abstract
(EN)
A zone dividing unit divides, on the basis of slope information included in the road information of a route along which an electric vehicle plans to travel, the route into a plurality of zones. A discharging plan candidate deriving unit derives, on the basis of the necessary capacity of a secondary battery, a plurality of discharging plans specified by a combination of the target SOC of the secondary battery at a starting time point and the target SOC thereof at a time point when reaching a destination. A zone degradation amount calculation unit calculates, with reference to a discharge degradation map specifying the relationship between a combination of the SOC use range of each zone and a discharge rate and a secondary battery degradation rate, a secondary battery degradation rate/amount of each zone on the basis of the SOC use range of each zone and the secondary battery output current of each zone. A discharging plan selection unit selects, among the plurality of discharging plans, a discharging plan with which the total degradation rate/amount is minimized.

Selon l'invention, une unité de division en zones divise, sur la base d'informations de pente comprises dans les informations routières d'un trajet le long duquel un véhicule électrique prévoit de se déplacer, le trajet en une pluralité de zones. Une unité de déduction de plan de décharge candidat déduit, en fonction de la capacité nécessaire d'une batterie secondaire, une pluralité de plans de décharge spécifiés par une combinaison du SOC cible de la batterie secondaire à un moment de départ donné et du SOC cible de celle-ci à un moment d'arrivée donné au point de destination. Une unité de calcul de valeur de dégradation de zone calcule, en se rapportant à une carte de dégradation de décharge spécifiant la relation entre une combinaison de la plage d'utilisation du SOC de chaque zone et d'un taux de décharge et d'un taux de dégradation de la batterie secondaire, un taux/une valeur de dégradation de la batterie secondaire de chaque zone en fonction de la plage d'utilisation du SOC de chaque zone et du courant de sortie de la batterie secondaire de chaque zone. Une unité de sélection de plan de décharge sélectionne, parmi la pluralité de plans de décharge, un plan de décharge avec lequel le taux/la valeur de dégradation totale est réduit(e) au minimum.

区間分割部は、電動車両で走行予定の経路の道路情報に含まれる勾配情報をもとに、前記経路を複数の区間に分割する。放電プラン候補導出部は、二次電池の必要容量をもとに、出発する時点の二次電池の目標SOCと、目的地に到着時点の目標SOCの組み合わせで規定される複数の放電プランを導出する。区間劣化量算出部は、各区間のSOC使用範囲および放電レートの組み合わせと、二次電池の劣化率の関係を規定した放電劣化マップを参照して、各区間のSOC使用範囲と各区間の二次電池の出力電流をもとに、各区間の二次電池の劣化率/劣化量を算出する。放電プラン選択部は、複数の放電プランの内、トータル劣化率/劣化量が最小となる放電プランを選択する。
