摘要： A device for detecting an open wire coupled to a battery includes a first pin and a second pin. The first pin is coupled to a positive terminal of a battery cell through a connection circuit. The second pin is coupled to a negative terminal of the battery cell through the connection circuit. A path of a current through the connection circuit changes in response to a wire between the connection circuit and the battery cell becoming open, and a change in a detecting voltage across the first pin and the second pin indicates a change in the path.

摘要： A circuit measures a cell voltage of a cell in a battery. The circuit includes a measurement circuit and a current generator. The measurement circuit includes a first terminal coupled to a positive terminal of a cell via a first resistive element and includes a second terminal coupled to a negative terminal of the cell via a second resistive element. The measurement circuit consumes a first current. The current generator generates a first compensation current according to the first current. The first current and the first compensation current flow from the positive terminal through the first resistive element to the first terminal. The measurement circuit calculates the cell voltage according to a first voltage difference between the first and second terminals when the first compensation current is disabled and according to a second voltage difference between the first and second terminals when the first compensation current is enabled.
