Мониторы состояния многоэлементных составных аккумуляторов

Семейство компонентов Analog Devices для мониторинга состояния многоэлементных высоковольтных составных аккумуляторов представлено полностью законченными микросхемами мониторинга аккумуляторов, которые включают в себя 16-разрядные АЦП, прецизионные источники опорного напряжения, мультиплексор с высоковольтными входами и последовательный интерфейс. Компоненты можно последовательно соединять без использования оптопар или изоляторов, что позволяет обеспечить мониторинг состояния каждой ячейки в длинной цепочке последовательно подключенных аккумуляторов. Эти микросхемы применяются в следующих приложениях: электромобили и гибридные автомобили, портативное оборудование большой мощности, системы резервного питания и высоковольтные системы сбора данных.
