Title (EN) CIRCUIT ARRANGEMENT FOR PROTECTION AGAINST AN UNDUE OVERHEATING
(FR) AGENCEMENT DE CIRCUIT POUR UNE PROTECTION CONTRE UNE SURCHAUFFE EXCESSIVE
Abstract:
(EN) A circuit arrangement for protection against an undue overheating of a charging and/or discharging control (3) and/or a secondary battery (2) is disclosed, the circuit arrangement (1) comprising the secondary battery (2), the charging and/or discharging control (3) for charging and/or discharging the secondary battery (2), a connector (4) for connecting the charging and discharging control (3) to an external power supply (5), at least one current limiting electronic component (7) arranged in electrical connection to the charging and/or discharging control (3) and optionally, a switchable load. It is provided that said charging and/or discharging control (3) is a dc-dc-converter, said current limiting electronic component (7) is disposed in the connection between the connector (4) for connecting the charging and/or discharging control (3) to the external power supply (5) and the charging and/or discharging control (3), and said current limiting electronic component (6, 7) is a Polymeric Positive Temperature Coefficient component.
(FR) L'invention concerne un agencement de circuit pour une protection contre une surchauffe excessive d'une commande de charge et/ou de décharge (3) et/ou d'une batterie secondaire (2), l'agencement de circuit (1) comprenant la batterie secondaire (2), la commande de charge et/ou de décharge (3) permettant de charger et/ou de décharger la batterie secondaire (2), un connecteur (4) permettant de connecter la commande de charge et de décharge (3) à une alimentation électrique externe (5), au moins un composant électronique de limitation de courant (7) disposé en connexion électrique avec la commande de charge et/ou de décharge (3) et éventuellement une charge commutable. Selon l'invention, ladite commande de charge et/ou de décharge (3) est un convertisseur continu-continu, ledit composant électronique de limitation de courant (7) est disposé dans la connexion entre le connecteur (4) pour connecter la commande de charge et/ou de décharge (3) à l'alimentation électrique externe (5) et à la commande de charge et/ou de décharge (3), et ledit composant électronique de limitation de courant (6, 7) est un composant de coefficient de température positif polymère.
