Method and Control Device for Controlling the Waste Heat Generated by an Electric Vehicle |
| 摘要 |
A method and a system are provided for controlling the waste heat generated by a motor vehicle having an electric drive, the electric drive including a rechargeable battery and an electric machine for driving the motor vehicle. The method includes the following acts: determining the thermal load on at least two components of the electric drive; if a first electric component of the electric drive has a lower thermal load than a second electric component, actuating the electric drive such that the generation of waste heat in the first electric component of the electric drive increases and the generation of waste heat in the second electric component of the electric drive does not increase; and if the second electric component of the electric drive has a lower thermal load than the first electric component, actuating the electric drive such that the generation of waste heat in the second electric component of the electric drive increases and the generation of waste heat in the first electric component of the electric drive does not increase. |

1. A method for controlling waste heat generated by a motor vehicle with an electric drive, wherein the electric drive comprises a rechargeable battery and an electric machine to drive the motor vehicle, the method comprising the acts of:
determining a thermal load of at least two components of the electric drive; if a first electric component of the electric drive has a lower thermal load than a second electric component, actuating the electric drive such that generation of waste heat in the first electric component of the electric drive increases and generation of waste heat in the second electric component of the electric drive does not increase; and if the second electric component of the electric drive has a lower thermal load than the first electric component, actuating the electric drive such that generation of waste heat in the second electric component of the electric drive increases and generation of waste heat in the first electric component of the electric drive does not increase. |
