Original Abstract Submitted
a battery management system comprising: a sequence of four or more battery connection terminals for connecting to a series of batteries; a resistance associated with each battery connection terminal; and a sequence of three or more adcs. each adc is associated with a pair of the battery connection terminals and is configured to convert the difference between the analogue voltages at its first and the second adc input terminals to a digital signal, and to provide that digital signal at its adc output terminal. the battery management system also includes a digital processor that is configured to, for each adc in the sequence: calculate an error voltage for the adc based on: i) the digital signal for the preceding adc in the sequence if there is one; and ii) the digital signal for the next adc in the sequence if there is one; and provide a measured-voltage output signal by subtracting the error voltage from the digital signal for the adc.
