1. A battery cell stack spacer compensating a thickness deviation of a stack of battery cells aligned along a first direction, the battery cell stack spacer comprising:
a first carrier member elongated along a second direction and a third direction, with a plane defined by the second direction and the third direction being perpendicular to the first direction, the first carrier member providing planar support to a base side of a first battery cell, the first carrier member comprising a first tab extending in the first direction;
a second carrier member elongated along the second direction and the third direction, the second carrier member providing planar support to a base side of a second battery cell, the second carrier member comprising a second tab extending in a fourth direction opposite the first direction; and
one or more tolerance compensation sheets sandwiched between the first carrier member and the second carrier member wherein the one or more tolerance compensation sheets each comprise one or more holes; and
wherein the first carrier member comprises one or more bolts, the bolts being arranged on the first carrier member such that each bolt projecting from the first carrier member penetrates, for each of the one or more tolerance compensation sheets, through one of the holes in the one or more tolerance compensation sheets.
