    CPC classification number: Y02E60/10 ,  H01M10/48

    Abstract: The present disclosure provides a voltage collection structure and a battery module having the voltage collection structure. The voltage collection structure includes: a fixed holder that is configured to be connected to multiple battery cores; a circuit board that is installed on the fixed holder; multiple voltage collection sheets that are installed on the circuit board and connected to the multiple battery cores. At least one voltage collection sheet includes a buffer segment, and at least a portion of the buffer segment protrudes in a direction that faces away from the battery core, so that the voltage collection sheet has a displacement allowance in a direction that is close to the battery core. A maximum protruding distance of the buffer segment ranges from 0.5 mm to 20 mm. The voltage collection structure according to the embodiments of the present disclosure can absorb a height difference between multiple battery cores, and the attachment tightness between the voltage collection sheet and each battery core is improved, so that reliable voltage collection of the battery core can be implemented.
