Abstract[English]
A new energy vehicle battery monitoring circuit having a wire containing multiple bends, the circuit comprising a temperature sensor (20) and a folded wire containing multiple bends (10). The temperature sensor (20) is arranged on a monitored battery (40) and is electrically connected to a signal transmission bus (30) by means of the folded wire containing multiple bends (10). The folded wire containing multiple bends (10) comprises a plurality of bent serpentine segments and straight-line segments. The bent serpentine segments and the straight-line segments are alternately arranged on the folded wire containing multiple bends (10). The plurality of straight-line segments are parallel to each other, and insulating outer cladding layers of adjacent straight-line segments are bonded to each other. The bonding force between adjacent straight-line segments is directly proportional to the distance from the corresponding bonding position to the temperature sensor (20), and the bonding force is smaller than a preset structural force bearing threshold. The plurality of bent serpentine segments do not overlap in the arrangement direction of the straight-line segments. According to the battery monitoring circuit, the operational stability of the circuit is improved, the safety of the signal transmission bus is guaranteed, and maintenance costs are reduced.[French]
L'invention concerne un circuit de surveillance de batterie de véhicule à énergie nouvelle comportant un fil contenant de multiples courbures, le circuit comprenant un capteur de température (20) et un fil plié contenant de multiples courbures (10). Le capteur de température (20) est disposé sur une batterie surveillée (40) et est électriquement connecté à un bus de transmission de signal (30) au moyen du fil plié contenant de multiples courbures (10). Le fil plié contenant de multiples courbures (10) comprend une pluralité de segments en serpentin courbé et de segments en ligne droite. Les segments en serpentin courbé et les segments en ligne droite sont disposés en alternance sur le fil plié contenant de multiples courbures (10). La pluralité de segments en ligne droite sont parallèles les uns aux autres, et des couches de gainage externe isolantes de segments en ligne droite adjacents sont liées les unes aux autres. La force de liaison entre des segments en ligne droite adjacents est directement proportionnelle à la distance de la position de la liaison correspondante au capteur de température (20), et la force de liaison est inférieure à un seuil de support de force structurale prédéfini. La pluralité de segments en serpentin courbé ne se chevauchent pas dans la direction d'agencement des segments en ligne droite. Selon le circuit de surveillance de batterie, la stabilité opérationnelle du circuit est améliorée, la sécurité du bus de transmission de signal est garantie, et les coûts de maintenance sont réduits.[Chinese]
