CPC G01R 31/367 (2019.01) [G01R 31/3835 (2019.01); H01M 10/425 (2013.01); H01M 10/482 (2013.01); H01M 2010/4271 (2013.01)] | 19 Claims |
1. A software-configurable battery management circuit, the battery management circuit comprising:
a plurality of cells arranged within a battery stack and configured to couple to a voltage node;
a plurality of switches coupled to the plurality of cells and configured to couple one or more of the plurality of cells to the voltage node;
an amplifier coupled to the voltage node via a resistive voltage divider, the amplifier amplifying:
individual cell voltages of the one or more of the plurality of cells; and
a voltage representative of a voltage at a top of the battery stack; and
a processor coupled to the amplifier, the processor performing steps comprising:
comparing a sum of the individual cell voltages of the one or more of the plurality of cells to the voltage at the top of a battery stack, including any wire voltage or bus bar voltage, to obtain a comparison result; and
based on the comparison result, determining whether the battery stack comprises at least one of a wire or a bus bar.
