Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a voltage signal acquisition module structure. Background technique [0002] As the core part of the electric vehicle, the power battery has a direct impact on the overall performance of the electric vehicle when it is in use. Therefore, during the operation of the battery, it is necessary to use a battery management system (BMS) to monitor the voltage of the battery, so as to monitor the quality of the battery operation at all times. [0003] However, most automotive battery modules use a traditional voltage signal acquisition structure for data acquisition, which has complex structures, complex fabrication, low production efficiency, and high manufacturing costs. [0004] Therefore, there is an urgent need for a voltage signal acquisition module structure to solve the above defects. Contents of the invention [0005] The purpose of the present invention is to provide a vo...
