Abstract: A battery core unit includes a battery core string and a sampling structure. The battery core string includes multiple battery core groups and at least one fixing support, the battery core groups are connected and disposed along a first direction, and two adjacent battery core groups are connected via a fixing support of the at least one fixing support. The sampling structure is electrically connected with the battery core groups, the sampling structure includes a notch, and the notch includes a limiting strip. The fixing support includes a first protrusion and a second protrusion, the first protrusion and the second protrusion are located in the notch and disposed spaced apart to form a spacing region, and the limiting strip is fitted in the spacing region.
