| 摘要 |
A method and system for monitoring a voltage of a battery cell or a battery stack. A first monitoring unit has a first plurality of battery monitoring nodes, first and second data ports, a first supply port switchably coupled to the first plurality of battery monitoring nodes, a second supply port switchably coupled to the first plurality of battery monitoring nodes, and a third supply port. A controller is connected to the first monitoring unit. Alternatively, a reference voltage may be connected to the controller or it may be connected to the first monitoring unit.
