1. A method for mounting a battery system to a chassis floor of an electrical vehicle, the battery system being adapted for providing electrical power for driving rolling movement of said electrical vehicle, a plane (P) extending through and parallel to said chassis floor with a first side of said plane (P) facing in a downward direction (D) during use of the electrical vehicle, the method comprising:
individually fixing battery modules of a plurality of battery modules to the chassis floor at the first side of said plane, each battery module comprising electrical terminals;
subsequently electrically connecting the electrical terminals of the battery modules to each other to form the battery system; and
subsequently fixing a cover plate to the chassis floor such that the cover plate covers the battery modules.
