1. A battery pack module (B), comprising:
a battery that comprises at least one battery cell, connectors and heat exchanger means, and
a battery housing that comprises:
a bottom enclosure that comprises a base and an upstanding peripheral wall, the bottom enclosure configured to contain the battery;
a lid configured to cap the bottom enclosure; and
fixation means for maintaining the lid on the bottom enclosure in order to close the battery housing,
characterized in that the lid comprises:
at least one protrusion positioned in order to press the battery towards the center of the module when the battery is contained inside the bottom enclosure and the lid is covering the bottom enclosure and retained by the fixation means inside the battery housing, wherein the at least one protrusion is in direct contact with the upstanding peripheral wall of the bottom enclosure,
wherein the coupled lid and bottom enclosure are configured to reduce the inner volume of the bottom enclosure available to the battery, and apply pressure to the battery toward the center of the battery pack module, wherein the pressure results in a compression force.
