A non-intrusion type charging device for a secondary battery for driving a heart pace maker by a non-contact induction power supply. A plurality of direction detection coils arranged in an annular shape detect a positional shift between a power transmission coil (9) and a power reception coil (4). The coil position shift information and information on charge voltage of an electric double-layer capacitor (6) are transmitted by a pulse signal to a primary side control circuit (15) outside a human body and displayed on a charge state display panel (16) and a coil shift amount display panel (18).

L'invention concerne un dispositif de charge de type non intrusif, destiné à une batterie secondaire pour la commande d'un stimulateur cardiaque par une alimentation électrique par induction sans contact. Une pluralité de bobines de détection d'orientation agencées en anneau détectent un décalage de position entre une bobine émettrice de puissance (9) et une bobine réceptrice de puissance (4). Des informations de décalage de position des bobines et des informations sur la tension de charge d'un condensateur électrique à couche double (6) sont transmises par un signal d'impulsion à un circuit de commande de côté primaire (15) situé à l'extérieur d'un corps humain puis affichées sur un panneau d'affichage d'état de charge (16) et un panneau d'affichage de niveau de décalage des bobines (18).
