Abstract:
A vehicle and vehicle system(s), comprising:a. two or more motor-generators, each having rotating components, and such that for the same input voltage two or more of the said motor-generators individually produce different power outputs, andb. one or more vehicle wheels, andc. a mechanical drive train that connects each said motor-generator to one or more vehicle wheels, andd. more than one rechargeable battery cell, ande. a system of electrical circuits comprising multiple circuit sections, with each said circuit section including one or more electrical on-off switches, andf. control means to set the said electrical on-off switches and thereby to control the function and use of the said motor-generators and said rechargeable battery cells, andg. for each said motor-generator, one or more combination(s) of the said electrical on-off switch settings, set by control means, that function(s) to connect more than one of the said multiple rechargeable battery cells in series with the said motor-generator and to operate said motor-generator as an electrical motor to drive said vehicle, andh. for each said motor-generator, one or more combination(s) of the said electrical on-off switch settings, set by control means, that function(s) to connect said motor-generator either individually to one said rechargeable battery cell or to multiple rechargeable battery cells in parallel, such that for a sufficiently high RPM of the said motor-generator's rotating components said motor-generator operates as a generator and charges said rechargeable battery cell(s).
