Title
(EN) ELECTRIC CHARGER FOR AN ACCUMULATOR OR BATTERY
(FR) CHARGEUR ÉLECTRIQUE POUR ACCUMULATEUR OU BATTERIE
Abstract
(EN)
The invention relates to an electric charger for an accumulator or a battery or the like, which is adapted for rapid charging during an on-period and comprises for this purpose control means for starting and ending the on-period. The charger is provided with a circuit for converting a supply voltage to a charging current for the battery, and further with a heat-absorbing member in heat-conducting coupling with at least an electrical component of the circuit to be protected against overheating. The control means are adapted such that the on-period cannot be restarted during an off-period following the on-period. The electric charger can hereby comprise a heat-absorbing member with a relatively low heat loss, this saving space and cost.
(FR)
La présente invention se rapporte à un chargeur électrique pour accumulateur ou batterie ou similaire, qui est conçu pour une charge rapide pendant une période d'activation et qui comprend, à cet effet, des moyens de commande servant à démarrer la période d'activation et à y mettre fin. Le chargeur est pourvu d'un circuit servant à convertir une tension d'alimentation en un courant de charge pour la batterie, ainsi que d'un élément d'absorption de chaleur en couplage thermoconducteur avec au moins un composant électrique du circuit à protéger contre la surchauffe. Les moyens de commande sont conçus de sorte que la période d'activation ne puisse pas redémarrer pendant une période de désactivation suivant la période d'activation. Le chargeur électrique peut ainsi comprendre un élément d'absorption de chaleur à perte de chaleur relativement faible, ce qui permet d'économiser l'espace et de diminuer le coût.
