Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a signal acquisition circuit and a battery management system. Background technique [0002] The battery management system is an important link connecting the vehicle battery pack and the electric vehicle, and is used to manage the battery pack. Usually, the battery management system is provided with a signal acquisition circuit for monitoring physical parameters of the battery pack. However, the traditional signal acquisition circuit can only monitor battery packs with a fixed voltage. Correspondingly, the battery management system can only manage battery packs with a fixed voltage, and the versatility is not high. Contents of the invention [0003] Based on this, it is necessary to provide a signal acquisition circuit and a battery management system for the technical problem of low versatility in the traditional method. [0004] A signal acquisition circuit inc...
