  • Publication number: 20180337375
    Abstract: A motor vehicle high-voltage energy accumulator having a housing with battery modules mounted inside, wherein the housing has a bottom wail, a top wail, a front end wail, a rear end wail, a left side wall, and a right side wall. In each case, two oppositely arranged wails of the>housing which are oriented in the longitudinal direction have load-path-forming supporting structure plates and cooling ducts through which cooling liquid flows. Here, the cooling ducts are either integrated directly into the supporting structure plate in the form of cavities or formed by the connection of a separate cooling structure plate to the supporting structure plate. The supporting structure plate and, where appropriate, the cooling structure plate increase the structural stability or the formation of cooling ducts.

  • Patent number: 10131247
    Abstract: An underbody unit for a motor vehicle body has a floor body (12) connectable to the motor vehicle body for dissipating static and/or dynamic loads. Reinforcing ribs (14) protrude up from the floor body (12). The reinforcing ribs (14) together with the floor body (12) delimit receiving pockets (16) for receiving battery cell units (18) of a traction battery for driving the motor vehicle. First and second connections (34, 36) supply and remove a refrigerating agent for cooling the floor body (12). The battery cell units (18) are above the floor body (12) and can be inserted into the underbody unit (10). Thus, the underbody unit (10), the reinforcing ribs (14) and the connections (34, 36) for the refrigerating agent define a supporting plate that can support the heavy battery cell units (18), form armor plating for protection and a heat exchanger for active and/or passive cooling.
