The present disclosure relates to electrical systems in general and embodiments of the teachings may include stabilization circuits for a vehicle electrical system comprising: a first connection for a first electrical system branch; a second connection for a pole of a first energy store of the first electrical system branch; a third connection for a second electrical system branch; a fourth connection for a third electrical system branch; a grounding connection for connection of the stabilization circuit to ground; a second energy store; a third energy store; a serial disconnection switch element between the second connection and the grounding connection; and a decoupling switch element connecting the first connection to the fourth connection. The second energy store is connected between the grounding connection and the third connection. The third connection is connected via the third energy store and a first converter to the fourth connection.

An electric powered vehicle includes a battery pack capable of storing electric energy, A fuel engine operated with a clean fuel. A generator or alternator 126 having communication with the engine, and supply electric energy to the electric driving motor A starter of the fuel engine activates when a sensed charge of the battery pack falls to or below the DMF value. Included is a second 128 and third generator or alternator 130 in communication with the fuel engine during periods when no electrical communication exists between the EDM and the battery pack. The second and third generators maintain an electrical output to the battery pack until the battery packs are fully charged. Included is a rear generator or alternator 152 in communication with a rear drive shaft assembly, or differential, including a level orientation sensor and a rotational velocity sensor communication between an output of such communication enabled upon any downhill motion of the vehicle above a predetermined operational velocity determined by the velocity sensor. A second rear generator 156 is controlled by an accelerator pedal, rpm sensor, electric clutch and is activated when no pressure is applied by a driver upon the accelerator pedal, permitting charging of the battery pack by the second rear generator 156 only upon a condition of zero acceleration. A third rear generator 300 is activated by the brake pedal and brake pedal switch does charge the battery packs 102/104.

A hybrid drive for a motor vehicle comprising a first transmission input shaft for connecting to a first internal combustion engine, a second transmission input shaft, which is coaxial to the first transmission input shaft and connects to a first electric motor, a layshaft, a first gear shifting device connecting the first transmission input shaft and the second transmission input shaft in a first shifting setting and engaging a gear in a second shifting setting, and a transmission output shaft.
