  "textContent": "A method of operating a control device (10) in a management system for battery cells (C), for instance for electric vehicles (EVs) or hybrid electric vehicles (HEVs), comprises sensing (30E, 40E, 300, 400), for each odd-numbered pair of charge-sensing pins and the subsequent even-numbered pair of charge-sensing pins in an ordered sequence of odd- and even-numbered pairs of charge-sensing pins sensing (30E, 40E, 300, 400) a first voltage drop (V12) indicative of the voltage drop across the charge sensing pins of the subsequent even-numbered pair (C11, C12) as well as second voltage drop (V11) indicative of the voltage drop across the charge sensing pins of the previous odd-numbered pair (C10, C11). As a result a faulty condition detected (a faulty ADC, for instance) first (V12') and second swapped voltage drops (V11') are swapped for the first (V12) and second voltage drops (V11), the swapped voltage drops being indicative of the voltage drop across the charge sensing pins of the previous odd-numbered pair (C10, C11) and the voltage drop (V11') between a charge distribution pin (S12) coupled (RDIS) to the charge sensing pin (C12) of the subsequent even-numbered pair (C11, C12) other than the common charge sensing pin (C11) and the common charge sensing pin (C11). The second swapped voltage drop (V11') is indicative of the voltage drop across the charge sensing pins of the subsequent even-numbered pair (C11, C12). As a result, voltages across the cells can still be measured with maintained accuracy irrespective of the fault.",
