System and method for detecting voltage of battery pack
A system and method for detecting voltage of a battery pack. The system comprises a level transfer circuit array, a multipath data selector, a decoder, a trimming calibration circuit, and an output buffer. The decoder is configured to parse a battery pack cell gating signal; the level transfer circuit array is configured to convert a gated battery pack cell voltage into a common grounded voltage; the multipath data selector is configured to transmit the common grounded voltage, which is converted by the level transfer circuit array, of a battery pack cell to the trimming calibration circuit; the trimming calibration circuit is configured to correct the received common grounded voltage of the battery pack cell; and the output buffer is configured to buffer the common grounded voltage, which is trimmed and calibrated by the trimming calibration circuit, of the battery pack cell.
