Abstract

L’invention concerne un chargeur solaire amovible pour charger une batterie qui alimente un appareil électrique tel qu’un appareil mobile. Un panneau solaire du chargeur solaire amovible est de préférence monté sur une surface extérieure d’un couvercle de compartiment de batterie pouvant être retiré par l’utilisateur. Les contacts de charge à l’intérieur du couvercle du compartiment de batterie sont en liaison électrique avec la batterie pour réaliser la charge de maintien de la batterie lorsque le couvercle est fermé. Un indicateur de charge peut fournir une indication selon laquelle l’appareil est en train de charger la batterie par le biais du panneau solaire. Le couvercle de compartiment de batterie à chargeur solaire et/ou la batterie pour un appareil particulier peuvent être achetés séparément de l’appareil, ce qui permet à un utilisateur d’améliorer un appareil actuel qui n’a pas été conçu à l’origine pour une charge solaire pendant que la batterie est en place. En variante, un appareil électrique neuf peut être fabriqué avec le couvercle de compartiment de batterie à chargeur solaire amovible et une batterie modifiée (ou d’autres composants nécessaires) pour permettre une charge de maintien.
