A battery storage system, for supplying electrical power to at least one electrical vehicle function, which is redundantly connected to the battery storage system by a first supply branch and a second supply branch includes a first connection and a second connection configured to connect to the first and the second supply branches; at least one ground connection; a connection line, which connects the first and the second connections; a cross-isolating switching apparatus arranged in the connection line and configured to interrupt the connection line; a first energy storage unit connected to the connection line between the first connection and the cross-isolating switching apparatus; and a second energy storage unit connected to the connection line between the second connection and the cross-isolating switching apparatus.

Battery storage system and on-board electrical system for supplying power in a fault-tolerant manner to safety-relevant loads in a vehicle

A cooling device is provided for an energy store that has an energy storage module. The cooling device has at least one cooling element and one spring fin. The spring fin is arranged on and coupled to the cooling element. The spring fin is configured to carry heat from the energy storage module to the cooling element.

Cooling device and energy store

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

Underbody unit for a motor vehicle

An underbody unit () for reinforcing a motor vehicle body of a motor vehicle has a floor body () that is connectable to the motor vehicle body for dissipating loads of the motor vehicle body. The floor body () has an upper side () for supporting battery cell units () of a traction battery for driving the motor vehicle purely electrically and at least one cooling channel () for cooling the upper side (). The floor body () and the underbody unit () form a supporting plate of a battery housing and can: support the battery cells () of the traction battery, form an armor plating to protect the battery cells () and define a heat exchanger that can actively and/or passively cool the battery cells () with the aid of the cooling channel ().

An underbody of a motor vehicle has a base plate () and an impact protector () connected a lower side of the base plate (). The impact protector () is a material composite composed of metal and fiber composite material.

Underbody of a motor vehicle

An underfloor unit () for protecting components of a motor vehicle, in particular a traction battery for electrically driving the motor vehicle, from ground impacts is provided. The underfloor unit () has a floor panel () for covering the motor vehicle component on the ground side and a plurality of separate impact protection tiles () connected to the floor panel () and intended for taking up ground impacts. As a result of the multiplicity of impact protection tiles (), only individual impact protection tiles () need be exchanged on being subjected to a hard absorbed ground impact, thus making it possible to have a motor vehicle with low maintenance and/or repair costs.

Underfloor unit for a motor vehicle

An underbody unit for a motor vehicle body has a floor body () connectable to the motor vehicle body for dissipating static and/or dynamic loads. Reinforcing ribs () protrude up from the floor body (). The reinforcing ribs () together with the floor body () delimit receiving pockets () for receiving battery cell units () of a traction battery for driving the motor vehicle. First and second connections () supply and remove a liquid cooling medium for cooling the floor body (). The battery cell units () are above the floor body () and can be inserted into the underbody unit (). Thus, the underbody unit (), the reinforcing ribs () and the connections () for the coolant define a supporting plate that can support the heavy battery cell units (), form armor plating for protection and a heat exchanger for active and/or passive cooling.
