Battery pack and battery holder

Abstract

Battery pack, characterized in that it comprises: a box body, a first partition and a second partition, wherein the box body comprises a base plate and the first partition and the second partition are arranged on the base plate, wherein the connection point between the first partition and the second partition has a sealed connection, wherein the first partition divides the interior of the box body into a battery compartment and an electrical compartment, which are arranged along a second direction, and the second partition divides the battery compartment into several independently sealed partial battery compartments, wherein several of the partial battery compartments are arranged along a first direction and the first direction and the second direction are parallel to the plane on which the base plate is located and the first direction and the second direction intersect, wherein a battery set is provided in the partial battery compartment;wherein the first partition is provided with a through-section which penetrates the first partition along the second direction; several conductive elements, wherein the several conductive elements are arranged sealed through the through-section and along the second direction one end of each conductive element is electrically connected to the battery pack, while the other end projects at least partially into the electrical compartment, wherein: one end of the second partition projects into the electrical compartment along the second direction, wherein the length projecting into the electrical compartment is L mm and L mm satisfies the relationship: L mm ≥ 10 mm; the conductive elements associated with the two adjacent partial battery compartments are located on both sides of the second partition along the first direction.;
