Abstract

A vehicle has a hybrid drive including an internal combustion engine and at least one electric motor. The hybrid drive has a charging device for generating an air flow. A charge air path guides the air flow from the charging device to the internal combustion engine. A charge air cooler is arranged in the charge air path between the charging device and the internal combustion engine. The hybrid drive has an electric battery for supplying electric power to the at least one electric motor. The effort involved in cooling the battery is reduced if the battery is incorporated into the charge air path between the charge air cooler and the internal combustion engine in such a way that the air flow can flow through and/or around it.

First claim

What is claimed is:

1. A vehicle comprising: a hybrid drive including (i) an internal combustion engine, (ii) at least one electric motor operatively arranged to drive the vehicle, (iii) a charging device for generating an air flow, and (iv) an electric battery for supplying electric power to the at least one electric motor, a charge air passage configured to guide air flow from the charging device to the internal combustion engine, a charge air cooler arranged in the charge air passage between the charging device and the internal combustion engine, and wherein the electric battery is incorporated into the charge air passage between the charge air cooler and the internal combustion engine such that the air flow can flow through and/or around the electric battery.

2. The vehicle as claimed in claim 1 , wherein the charge air passage has a battery bypass for bypassing the electric battery.

3. The vehicle as claimed in claim 2 , wherein the charge air passage has a battery bypass valve for controlling the battery bypass, wherein, in a first valve position of the battery bypass valve, the air flow can flow through and/or around the battery, and, in a second valve position of the battery bypass valve, the air flow can bypass the electric battery.

4. The vehicle as claimed in claim 1 , wherein the electric battery has a battery housing and a plurality of battery cells arranged in the battery housing, and the electric battery is incorporated into the charge air passage such that the air flow can flow through the battery housing and around the battery cells.

5. The vehicle as claimed in claim 1 , further comprising an electric delivery device for delivering the air flow and that is arranged in the charge air passage between the charging device and the charge air cooler.

6. The vehicle as claimed in claim 5 , further comprising a heating device for heating the air flow arranged in the charge air passage between the electric delivery device and the electric battery.

7. The vehicle as claimed in claim 1 , further comprising a heating device for heating the air flow arranged in the charge air passage between the charge air cooler and the electric battery.

8. The vehicle as claimed in claim 1 , wherein the charge air passage has an internal or external engine bypass for bypassing the internal combustion engine.

9. The vehicle as claimed in claim 8 , wherein the charge air passage has an engine bypass valve for controlling the engine bypass, wherein in a first valve position of the engine bypass valve, the air flow reaches the internal combustion engine, and, in a second valve position of the engine bypass valve, the air flow bypasses the internal combustion engine.

10. The vehicle as claimed in claim 1 , wherein the charging device is configured as an exhaust gas turbocharger.
