Rotational energy storage for use in multi-voltage electrical system of hybrid motor vehicle, has low-voltage coil arranged in excitation region of magnetic field such that magnetic field device is displaced from low voltage coil

摘要

The storage (3) has a magnetic field generating device for generating magnetic field. A low-voltage coil (32) is arranged in an excitation region of the magnetic field such that a magnetic field device (30) is rotatably displaced from the low voltage coil to convert kinetic energy in form of rotational energy into electrical energy for a low voltage network. The electrical energy from the low voltage network is coupled with low voltage at the low voltage coil, where the low voltage comprises a low voltage level. An independent claim is also included for a multi-voltage electrical system comprising a high-voltage network.
