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.

摘要： A circuit used to measure cell voltages in a battery pack can include a cell voltage level shifter, a sense block, and a compensation current generator. The cell voltage level shifter selects a cell and shifts the terminal voltages of the selected cell from a first voltage level to a second voltage level. The sense block monitors the current consumed by the level shifter, and generates a signal indicative of the consumed current. The compensation current generator generates compensation currents to compensate the current consumed by the level shifter. Therefore, unbalance of the cell capacities caused by the current consumed by the level shifter can be reduced or eliminated, and thus the overall capacity of the battery pack can be improved.

摘要： A negative terminal voltage of a cell is changed from a first to a second negative terminal voltage so that a cell voltage is changed from a first to a second output voltage. A differential-mode calibration parameter is calculated based on a difference between the first and second output voltages and a difference between the first and second negative terminal voltages. The negative terminal voltage of the cell is then changed from the first to second negative terminal voltage so that the positive terminal voltage of the cell is changed from a first to a second positive terminal voltage and the output voltage is changed from a third to a fourth output voltage. A common-mode calibration parameter is calculated based on the differential-mode calibration parameter and a difference between the third and fourth output voltages and a difference between the first and second positive terminal voltages.
