Electric hybrid vehicle
First Claim
1. A hybrid vehicle assembly comprising:
- an electric motor/generator, which is operable as a motor and as an electrical energy generator;
an engine;
a connection between the electric motor/generator and the engine;
a first electrical storage mechanism connected to the electric motor/generator for selectively powering the electric motor/generator;
an energy conversion device continuously connected to the engine;
a second electrical storage mechanism; and
a voltage reducer coupled to the first electrical storage mechanism, the energy conversion device and the second electrical storage mechanism so as to provide charge from the first electrical storage mechanism, the energy conversion device and the electrical energy generator to the second electrical storage mechanism.

Abstract
A hybrid vehicle is provided, which includes an electric motor, an engine, first and second electrical storage mechanisms, an energy conversion device and a voltage reducer. The electric motor and the engine are drivably connectable to propel the vehicle. The first electrical storage mechanism powers the electric motor. The energy conversion device is continuously coupled to the engine for providing a charging power output to the first electrical storage mechanism whenever the engine is running. The second electrical storage mechanism provides power to vehicle accessories at a lower voltage than the first electrical storage mechanism. The voltage reducer has an input coupled to the generator and the first electrical storage mechanism and has an output coupled to the second electrical storage mechanism to provide charging power at the lower voltage to the second electrical storage mechanism.
