1. A battery module comprising:
a battery module housing,
a battery cell package, which comprises a plurality of battery cells, arranged in the battery module housing, wherein a vertically oriented outer face of the battery cell package is arranged to face an inner face of a wall of the battery module housing,
a battery cell monitoring unit connected to the battery cells via a signal line,
a protective plate arranged between the outer face of the battery cell package and the inner face of the battery module housing, wherein the protective plate covers the vertically oriented outer face of the battery cell package, and
a recess disposed on a side of said protective plate that either faces toward or away from the battery cell package, in which recess at least one portion of the signal line is arranged,
wherein each of the plurality of battery cells, the at least one portion of the signal line, the protective plate and the inner face of the battery module housing are all arranged vertically and parallel to one another in a stacked formation,
wherein each of the plurality of battery cells, the protective plate and the wall of the battery module housing has a substantially rectangular shape having a length dimension, a height dimension measured between top and bottom edges that is less than the length dimension, and a thickness dimension that is less than the height dimension, wherein the length dimensions are oriented in a same direction, and whereby the at least one portion of the signal line extends horizontally along the length dimension of the protective plate at a vertical location between the top and bottom edges of the protective plate.
