Abstract

A motor vehicle having an electrical energy reservoir with a battery housing having at least one fluid outflow opening. An underride protection plate is arranged below the electrical energy reservoir. At least a first flow channel is configured between the battery housing and the underride protection plate. At least a second flow channel is configured within the underride protection plate. The underride protection plate includes at least one inflow opening to the at least one second flow channel and at least one outflow opening from the at least one second flow channel. The at least one fluid outflow opening of the battery housing communicates with the at least one inflow opening by way of the at least one first flow channel.

Claims (26)

1 . A motor vehicle comprising:

an electrical energy reservoir including a battery housing having at least one fluid outflow opening,

an underride protection plate arranged below the electrical energy reservoir,

at least one first flow channel disposed between the battery housing and the underride protection plate and at least one second flow channel is disposed within the underride protection plate,

wherein the underride protection plate comprises an at least two-layer structure having a first outer plate, a second outer plate, and one or more underride protection plate spacer elements arranged between the two outer plates for forming the at least one second flow channel between the first outer plate and the second outer plate,

wherein the underride protection plate further comprises at least one inflow opening to the at least one second flow channel and at least one outflow opening from the at least one second flow channel,

wherein the at least one fluid outflow opening of the battery housing communicates with the at least one inflow opening by way of the at least one first flow channel.

2 . The motor vehicle according to claim 1 , further comprising one or more first spacer elements arranged between the battery housing and the underride protection plate in order to form the at least one first flow channel between a bottom side of the battery housing and a top side of the underride protection plate.

3 . The motor vehicle according to claim 2 , wherein the one or more first spacer elements are arranged and configured such that the at least one first flow channel follows a meandering course.

4 . The motor vehicle according to claim 2 , wherein the one or more first spacer elements constitute a layer-like component including an intermediate plate.

5 . The motor vehicle according to claim 1 , wherein the one or more underride protection plate spacer elements include an intermediate plate.

6 . The motor vehicle according to claim 1 , wherein the one or more underride protection plate spacer elements are arranged and configured such that the at least one second flow channel follows a meandering course.

7 . The motor vehicle according to claim 1 , wherein the at least one first flow channel and the at least one second flow channel are arranged substantially above one another and/or the one or more first spacer elements and the one or more underride protection plate spacer elements are arranged substantially above one another.

8 . A motor vehicle comprising:

an electrical energy reservoir including a battery housing having at least one fluid outflow opening,

an underride protection plate arranged below the electrical energy reservoir,

at least one first flow channel disposed between the battery housing and the underride protection plate and at least one second flow channel is disposed within the underride protection plate,

wherein the underride protection plate comprises at least one inflow opening to the at least one second flow channel and at least one outflow opening from the at least one second flow channel,

wherein the at least one fluid outflow opening of the battery housing communicates with the at least one inflow opening by way of the at least one first flow channel,

wherein the at least one fluid outflow opening is arranged substantially in a center of the motor vehicle when viewed in a transverse direction and/or arranged laterally towards a driver side of the motor vehicle and/or laterally towards a passenger side of the motor vehicle, and/or that the at least one inflow opening is arranged substantially in the center of the motor vehicle when viewed in the transverse direction and/or laterally towards the driver side of the motor vehicle and/or laterally towards the passenger side of the motor vehicle, and/or that the at least one outflow opening is arranged substantially in the center of the motor vehicle when viewed in the transverse direction and/or laterally towards the driver side of the motor vehicle and/or laterally towards the passenger side of the motor vehicle.

9 . A motor vehicle comprising:

an electrical energy reservoir including a battery housing having at least one fluid outflow opening,

an underride protection plate arranged below the electrical energy reservoir,

at least one first flow channel disposed between the battery housing and the underride protection plate and at least one second flow channel is disposed within the underride protection plate,

wherein the underride protection plate comprises at least one inflow opening to the at least one second flow channel and at least one outflow opening from the at least one second flow channel, wherein the at least one fluid outflow opening of the battery housing communicates with the at least one inflow opening by way of the at least one first flow channel,

wherein the at least one fluid outflow opening is arranged substantially in a center of the motor vehicle when viewed in a longitudinal direction and/or arranged forward in a direction of a front of the motor vehicle and/or rearward in the direction of a rear of the motor vehicle, and/or that the at least one inflow opening is arranged substantially in the center of the motor vehicle when viewed in the longitudinal direction and/or forward in the direction of the front of the motor vehicle and/or rearward in the direction of the rear of the motor vehicle, and/or that the at least one outflow opening is arranged substantially in the center of the motor vehicle when viewed in the longitudinal direction and/or forward in the direction of the front of the motor vehicle and/or rearward in the direction of the rear of the motor vehicle.
