Title (EN) METHOD FOR PREHEATING A BATTERY OF AN ELECTRICALLY OPERATED MOTOR VEHICLE, AND CHARGING DEVICE
(FR) PROCÉDÉ POUR PRÉCHAUFFER UNE BATTERIE D'UN VÉHICULE AUTOMOBILE ÉLECTRIQUE ET DISPOSITIF DE CHARGE
(DE) VERFAHREN ZUM VORWÄRMEN EINER BATTERIE EINES ELEKTRISCH BETRIEBENEN KRAFTFAHRZEUGS SOWIE LADEVORRICHTUNG
Abstract:
(EN) The invention relates to a method for preheating a battery (4) of an electrically driven motor vehicle (2), in particular an electric vehicle or a hybrid vehicle, wherein a charging process and a discharging process of the battery (4) are controlled in such a way that a minimum temperature (Tmin) of the battery (4) is attained at a departure time (tA) of the motor vehicle (2). The invention further relates to a charging device (6) for said type of motor vehicle (2) and to a motor vehicle (2) comprising said type of charging device (6).
(FR) L'invention concerne un procédé pour préchauffer une batterie (4) d'un véhicule automobile (2) à propulsion électrique, en particulier d'un véhicule électrique ou d'un véhicule hybride, un processus de charge et un processus de décharge de la batterie (4) étant commandés de sorte qu'une température minimale (Tmin) de la batterie (4) soit atteinte à un instant de démarrage (tΑ) du véhicule automobile (2). L'invention concerne en outre un dispositif de charge (6) d'un véhicule automobile (2) de ce type, ainsi qu'un véhicule automobile (2) équipé d’un tel dispositif de charge (6).
(DE) Die Erfindung betrifft ein Verfahren zum Vorwärmen einer Batterie (4) eines elektrisch angetriebenen Kraftfahrzeugs (2), insbesondere eines Elektrofahrzeugs oder eines Hybridfahrzeugs, wobei ein Ladevorgang und ein Entladevorgang der Batterie (4) derart gesteuert werden, dass eine Mindesttemperatur (Tmin) der Batterie (4) zu einer Abfahrtszeit (tΑ) des Kraftfahrzeugs (2) erreicht ist. Des Weiteren betrifft die Erfindung eine Ladevorrichtung (6) eines derartigen Kraftfahrzeugs (2) sowie ein Kraftfahrzeug (2) mit einer solchen Ladevorrichtung (6).
