Modelo: Battery System-Rigid Copper Busbar
Marca: htd
Origin: PORCELANA
Lugar de origen: PORCELANA
Posicionamiento del producto:
La barra colectora positiva/negativa principal del paquete HTD es el componente conductor central dentro del paquete de baterías de energía, responsable de la entrada y salida de corriente total del sistema. Como "aorta eléctrica" del paquete de baterías, conecta los módulos de batería a la interfaz externa de alto voltaje. Este producto utiliza cobre T2 de alta conductividad (pureza ≥99,9%) y logra conexiones de baja impedancia y alta corriente dentro de un espacio limitado mediante procesos de integración de aislamiento y estampado de precisión. Admite un funcionamiento estable a largo plazo de -40 °C a 105 °C, con un aumento de temperatura de ≤40 K a la corriente nominal. Su diseño compacto aumenta la utilización del espacio del módulo en más de un 15%, lo que lo convierte en un componente clave para garantizar la seguridad y la eficiencia energética del sistema de batería.
