| 摘要 |
The invention relates to a method for operating an electrical auxiliary heater in a motor vehicle, said heater comprising at least one rechargeable electrochemical cell as the power source and an electrical generator connected to the power source and driven by a drive motor of the motor vehicle, the electrical auxiliary heater being supplied with power from the generator when the drive motor is running. According to the invention, the electrical auxiliary heater can also be supplied with power as required, when it is not supplied with power by the generator, by being connected to at least one electrochemical cell as the power source. The invention is characterised in that the charging state of at least one electrochemical cell is monitored, and a power supply of the electrical auxiliary heater, generated by the monitored at least one electrochemical cell, is interrupted again if the charging state of the monitored at least one electrochemical cell does not reach a lower threshold value. |
