Battery pack

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, wherein the first opening is arranged on a first surface of the battery housing, and wherein the battery housing has a cell pole projecting from the first opening;a first insulating element comprising a first segment and a second segment connected to each other, the first segment at least partially covering the first surface of at least one of the individual batteries, the second segment being arranged between two adjacent individual batteries; wherein a dimension of the first segment in the first direction is w mm, a dimension of the second segment in the second direction is d mm, a minimum distance between edges of the first openings of two adjacent individual batteries in the first direction is L mm, wherein: 60 ≤ L(w+d) ≤ 1110; a dimension of the individual battery in the second direction is D mm, wherein: 0.01 ≤ d / D ≤ 1.;
