Abstract
A battery housing for a vehicle driven by an electric motor to be installed in the floor region of a vehicle. The battery housing has a frame, which encloses at least one battery module, and a floor, which is connected to the frame. The floor takes the form of a sandwich construction and forms hollow chambers, which can be used as temperature-control channels for guiding through a fluid by virtue of end-side openings in adjacent hollow chambers being connected to one another at their two ends.
Claims14
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.
