Title (EN) CURRENT INTERRUPT DEVICE FOR SECONDARY BATTERIES
(FR) DISPOSITIF D'INTERRUPTION DE COURANT POUR ACCUMULATEURS SECONDAIRES
Abstract:
(EN) A secondary battery (100) includes a cell (110) having a positive terminal (115) and a negative terminal (120), a device (130, 140) for coupling the positive terminal (115) to the negative terminal (120) in response to swelling of the cell (100), and a fuse (125) coupled between the positive terminal (115) and the negative terminal (120) in response to swelling of the cell (110). According to another aspect of the present invention, a secondary battery (700) has external contacts (150, 155) and includes a cell (110) having a positive terminal (115) and a negative terminal (120) that are coupled to the external contacts (150, 155) during normal cell operation. In response to swelling of the cell (110), a device (705, 720, 725, 730, 735) decouples at least one of the positive and negative terminals (115, 120) from at least one of the external contacts (150, 155) in response to swelling of the cell (110).
(FR) Cet accumulateur secondaire (100) comporte une cellule (110) pourvue de deux bornes, positive (115) et négative (120), d'un organe (130, 140) de couplage des deux bornes en réaction au gonflement de la cellule (100) et un fusible (125) monté entre les bornes positive (115) et négative (120) en réaction au gonflement de la cellule (110). Selon un autre aspect de l'invention, l'accumulateur secondaire (700) est pourvu de contacts extérieurs (150, 155) et comporte une cellule (110) dont les bornes, positive (115) et négative (120), sont couplées aux contacts extérieurs (150, 155) lors du fonctionnement normal de la cellule. En réaction au gonflement de la cellule (110), un mécanisme (705, 720, 725, 730, 735) découple l'une au moins des deux bornes (115, 120) de l'un au moins des contacts extérieurs (150, 155) en réaction au gonflement de la cellule (110).
