1. A battery housing for a vehicle driven by an electric motor, to be installed in a floor region of the vehicle, comprising:
a frame enclosing at least one battery module and a floor connected to the frame, wherein the floor is equipped with collision protection, wherein the floor is designed as a sandwich construction which comprises a lower sheet, an upper sheet spaced apart from the lower sheet, and a structural sheet positioned in between and connected to the lower sheet and to the upper sheet,
wherein the structural sheet is formed, at least in sections in its cross-section, from a repeating sequence comprising a first contact section, a first bridging section, a second contact section, and a second bridging section,
wherein the first contact section is connected to the lower sheet and the second contact section is connected to the upper sheet, wherein the bridging sections each have a first contact section connected to the lower sheet with a second contact section connected to the upper sheet, and wherein the bridging sections extend over the entire longitudinal or transverse extension of the structural sheet,
wherein hollow chambers formed by the upper sheet and the structural sheet with its bridging sections and the second contact sections connecting them are usable as temperature-control channels for conducting a fluid, and wherein end-side openings of adjacent hollow chambers are connected to one another at ends thereof in such a manner that the end-side openings of adjacent hollow chambers are connected to one another at the ends thereof offset in relation to one another, resulting in a meandering temperature-control line.
