Motor vehicle having a latent heat accumulator and method of charging the accumulator

摘要

The invention is directed to a motor vehicle having an internal combustion engine 2 which drives the vehicle via a drive shaft 4. The motor vehicle further includes a latent heat accumulator 18. In addition, the motor vehicle includes an electrical machine 8 which is at least at intervals of time coupled to the drive shaft 4 so that the rotational energy of the drive shaft 4 can be converted into electrical energy with the aid of the electrical machine 8. The electrical energy is supplied to the latent heat accumulator 18 and is there converted into heat energy to charge the latent heat accumulator 18.
