Patent

CA 2307193

A cap (8) for covering an open side of a battery case (15) containing a power generation element (51) includes a protective circuit with an electric circuit (11) formed on a circuit board (10). The circuit board (10) is mounted outside the cap (8). A positive terminal block (16) acting as positive terminals of rechargeable battery (A) and an S-pole terminal block (14) for controlling the operation of the electric circuit (11) by an external connection are provided on the outside of the circuit board (10). Since the protective circuit is provided in the cap so as to protect the battery from excessive discharge or charge, there is no need for provision of a packed cell.

Un couvercle (8) destiné à recouvrir le côté ouvert d'un boîtier (15) d'une batterie renfermant un élément générateur d'énergie (51) comprend un circuit de protection avec un circuit électrique (11) formé sur une plaquette de circuit imprimé (10). La plaquette de circuit imprimé (10) est montée à l'extérieur du couvercle (8). Un bloc de connexion positive (16) agissant comme borne positive d'une batterie rechargeable (A) et un bloc de connexion à pôle S (14) pour la commande du fonctionnement du circuit électrique (11) par une connexion externe, sont prévus à l'extérieur de la plaquette de circuit imprimé (10). Du fait que le circuit de protection est prévu dans le couvercle pour protéger la batterie d'une décharge ou d'une charge excessive, il n'est pas nécessaire de prévoir un élément sous boîtier.
