| 摘要 |
The invention concerns a device for measuring differential voltages sensed at the terminals of multiple sets (2) of battery elements mounted in series, each set having a reference voltage, an output voltage and a differential voltage equal to the difference between the reference and output voltages while wishing to provide its differential voltage relative to a reference potential different from its reference voltage, the differential voltage of a set is transformed into a stream of signals capable of being directly processed as a logic signals by centralized processing means (5), the stream of signals, prior to processing, being sent on a galvanic insulation means (4). The invention is suitable for vehicle batteries. |
