Abstract

A motor vehicle with an energy storage device with at least one electric energy store and an air conditioning device for an active control of the temperature of the energy store accommodated in a housing. At least one air inlet opening and at least one air outlet opening are provided at the housing, and an ambient air stream can be guided by the air inlet opening into the housing and by the air outlet opening from the housing for passive cooling.

First claim

The invention claimed is:

1. A motor vehicle, comprising:
an energy storage device with at least one electric energy store and an air conditioning device for active regulation of the temperature of the energy store, wherein the energy store is accommodated in a housing, wherein in the housing is provided at least one air inlet opening and at least one air outlet opening, and an ambient air stream can be guided through the air inlet opening into the housing and through the air outlet opening out of the housing for passive cooling,
wherein a regulation device is provided, which regulates the ambient air stream through the air inlet opening and through the air outlet opening,
wherein the regulating device is provided with at least one adjustable flap for closing the air inlet opening and the air outlet opening, wherein the flap is controlled by a control device so that the flap can be moved between an opened position and a closed position, and
wherein the flap is arranged so that the flap is at least partially visible in the area of the motor vehicle front.

2. The motor vehicle according to claim 1 , wherein the energy storage device is arranged in an area between a motor vehicle front and a passenger cell, so that the ambient air stream that is generated by the headwind and by the ambient air stream and that is impacting the vehicle front can be guided through the air inlet opening into the housing.

3. The motor vehicle according to claim 2 , wherein the air inlet opening is arranged at a side of the housing directed toward the motor vehicle front, and the air outlet opening is arranged at a side of the housing directed toward a rear of the motor vehicle.

4. The motor vehicle according to claim 1 , wherein at least one air guiding channel is provided which is connected with one end of the housing, and the flap is attached at another end of the air guiding channel, which is arranged in the area of the motor vehicle front.

5. The motor vehicle according to claim 1 , wherein a control device is configured to control the regulating device as a function of a temperature of the energy store and of an ambient temperature of the motor vehicle and as a function of a driving speed of the motor vehicle and as a function of a stored thermal energy storage device model.

6. The motor vehicle according to claim 5 , wherein the control device is designed to control the regulating device as a function of the sensor data detected by a rain sensor.

7. An energy storage device, comprising:
at least one electric energy store and a housing having at least one air inlet opening and at least one air outlet opening, wherein an ambient air stream can be guided through an air inlet opening into the housing and through the air outlet opening from the housing for passive cooling,
wherein a regulation device is provided, which regulates the ambient air stream through the air inlet opening and through the air outlet opening,
wherein the regulating device is provided with at least one adjustable flap for closing the air inlet opening and the air outlet opening, wherein the flap is controlled by a control device so that the flap can be moved between an opened position and a closed position, and
wherein the flap is arranged so that the flap is at least partially visible in the area of the motor vehicle front.

8. The energy storage device according to claim 7 , wherein a regulating device is provided, which can adjust the ambient air stream by an air inlet opening and an air outlet opening.

9. The energy storage device according to claim 8 , wherein the regulating device includes at least one adjustable flap for closing the air inlet opening and the air outlet opening, wherein the flap is controlled so that the flap can be moved between a closed position and an open position by a control device.

10. The energy storage device according to claim 9 , wherein the storage device is configured to control the regulating device as a function of at least one of a temperature of the energy store, an ambient temperature, sensor data detected by a rain sensor, and as a function of a thermal energy storage device model stored in the control device.
