Title:
SYSTEM AND METHOD FOR DETECTING VOLTAGE OF BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2016/082290
Kind Code:
A1
Abstract:
A system and method for detecting voltage of a battery pack. The system comprises a level transfer circuit array (12), a multipath data selector (13), a decoder (11), a modification and calibration circuit (14) and an output buffer (15). The decoder (11) is used for obtaining through parsing a cell gating signal of the battery pack (2). The level transfer circuit array (12) is used for converting the voltage of a gated cell in the battery pack (2) into a common ground voltage. The multipath data selector (13) is used for transmitting, to the modification and calibration circuit (14), the common ground voltage of the cell in the battery pack (2) that is obtained through conversion by the level transfer circuit array (12). The modification and calibration circuit (14) is used for modifying the received common ground voltage of the cell in the battery pack (2). The buffer (15) is used for buffering the common ground voltage of the cell in the battery pack (2) after modification and calibration by the modification and calibration circuit (14). According to the detecting system and method, only the circuits related to sampling of the required battery voltage are switched on, so the power consumption of the system is largely reduced on the premise that the conversion speed is not affected, and the output accuracy of the system for detecting voltage of a battery pack and the reliability of the system in the case of anomalies are improved.
