Abstract:
1. A method for converting an existing internal combustion vehicle to an internal combustion-electric hybrid comprising the steps of: providing an electric storage battery comprising a plurality of rechargeable cells in series adjacent connections, each cell having a positive and a negative terminal; connecting a charger to the battery to recharge it using alternating current electric power derived from an alternating current receptacle or an inductive connection; providing a controller receiving direct current electric power from the battery and an accelerator signal from the driver along with signal input devices and instruments which provide controllable electric power to an electric motor; and mechanically connecting an electric motor directly to a universal joint of a drive shaft of the vehicle by a power transmission subsystem at a point of minimum motion of the drive shaft relative to the frame of the vehicle; said power transmission subsystem comprising a flexible speed reduction drive such that the electric motor can provide some or all of the mechanical power required to propel the vehicle while accepting some relative motion between the existing vehicle drive train and the electric motor.
