1. A battery case for at least one battery module comprising:
a. a frame-like support structure suitable to be interconnected to an electric vehicle,
b. the frame-like support structure encompassing a frame opening, wherein the frame-like support structure comprises and/or is interconnected to at least one crash-element foreseen to absorb impact energy introduced from the outside in the plane formed by the frame-like support structure,
c. a tub-shaped insert, which is arranged in the frame opening and interconnected to the frame-like support structure, wherein the tub-shaped insert comprises at least one base section comprising at least one cooling plate which in an assembled position with the tub-shaped insert is in thermal contact with the at least one battery module arranged in the tub-shaped insert, and
d. a closure suitable to close and the tub-shaped insert to form a compartment for the at least one battery module,
e. wherein the at least one cooling plate is arranged inside or outside the compartment, and
f. wherein the frame-like support structure comprises two first outer beams extending in a first spatial direction and two second outer beams extending in a second spatial direction arranged essentially perpendicular to the first spatial direction, the first and second outer beams forming a load bearing structure encompassing the tub-shaped insert circumferentially, and
g. wherein at least one first inner beam is arranged in the first direction interconnecting the two second outer beams arranged opposite to each other and at least one second inner beam is arranged in the second direction interconnecting the two first outer beams arranged opposite to each other.
