Battery pack and its battery set

Abstract

Battery set, characterized in that it comprises: at least two individual batteries, wherein the individual batteries are arranged sequentially in a first direction, wherein each individual battery comprises a battery housing and a coated insulating layer enclosing a surface of the battery housing, wherein a first opening is arranged in the insulating layer, wherein the first opening exposes a part of the battery housing, wherein the first openings of the at least two individual batteries are located on the same side of the battery set in a second direction, wherein the first direction is perpendicular to the second direction, and wherein the first opening is arranged on a first surface of the battery housing;a first insulating element comprising a first segment and a second segment connected to each other, wherein the first segment at least partially covers the first surface of at least one of the individual batteries, and wherein the second segment is arranged between two adjacent individual batteries; wherein a dimension of the first segment in the first direction is w mm, and a dimension of the second segment in the second direction is d mm, and wherein a minimum distance between edges of the first openings of two adjacent individual batteries in the first direction is L mm, and wherein: 60 ≤ L(w+d) ≤ 1110.;
