Позиционирование продукта:
Интегрированная сенсорная шина HTD — это интеллектуальный компонент внутри аккумуляторного модуля, который обеспечивает интегрированный сбор тока, выборку напряжения и сбор сигналов температуры. Благодаря интеграции гибких печатных плат (FPC), медных/алюминиевых проводников и изоляционных структур он заменяет традиционные дискретные жгуты проводов. Он выполняет функции сильноточной шины, одновременно собирая сигналы напряжения и температуры элементов в режиме реального времени и передавая их в систему управления батареями (BMS). Это ключевой компонент для повышения интеллекта, точности управления и безопасности аккумуляторной батареи.
