Abstract
Abstract Two banks of series-connected batteries are alternately charged by an engine driven generator under control of a change-over selector. While one bank of batteries is being charged the other bank powers a drive motor for vehicle propulsion at a speed controlled by selection of power terminals in each battery bank, at different voltage levels, from which the drive motor is energized.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
In combination with a vehicle having a fuel combustion engine, a drive propelling transmission, a drive motor connected to the transmission for propelling the vehicle, a generator driven by the engine, at least two energy storing battery assemblies each having a plurality of power terminals at different energy levels, a charging circuit connected to the generator for storing energy developed by the generator in the battery assemblies, selector means connected to the charging circuit for selecting one of the battery assemblies within which said energy is stored, and speed controlling means connecting the drive motor to a selected one of the power terminals in the other of the battery assemblies for energizing the drive motor with energy stored at a corresponding one of the energy levels.
Claim 2
Dependent Claim
