Abstract
An Electric Vehicle Having Exchangeable Battery Modules and Method of Resupply Therefor. The device of the present invention is a electrically-powerable vehicle that provides the user with a usage pattern very similar to one experienced through use of an internal-combustion-powered vehicle. That is to say that the operating cost for the vehicle is “pay as you go,” rather than the user needing to pay an exorbitant up-front fee in order to purchase the vehicle. In order to accomplish this, the battery modules for use in the vehicle are exchangable by an individual driver. As a battery module becomes discharged, the user is able to visit a recharging station and exchange his or her discharged battery module with a fully charged module. The user is then be charged an amount that is relative to the number of exchanges and/or re-charge energy consumed. In order to enable this sort of system, and the battery modules are of standard size, and interface with a module tracking and monitoring system. The vehicle purchaser is able to purchase a vehicle without purchasing the battery modules, and then simply rent or lease the battery modules, as desired. Finally, the vehicle has an internal power mode selector switch system that permits the user to select different circuitry alignments for the power being supplied by the battery modules, including parallel, serial and individual. This allows the driver to control the trip length and our propulsion power available to the driver.

7. An electric vehicle and charging method therefor, comprising the steps of:
-
obtaining an electric vehicle having two or more exchangeable battery module receptacles and an electric motor; obtaining one or more battery modules cooperatively designed to interface with said receptacles; installing one or more said battery modules into said receptacles; charging said installed battery modules; exchanging one or more said installed battery modules with a charged said battery module whereby one or more installed battery module is removed from said receptacles and one or more charged battery module is installed in said receptacles; measuring the electrical charge remaining in said removed modules and responsively assigning a net charge value used for each said removed battery module; and wherein said electric vehicle further comprises; a power mode selector device electrically connected between said two or more battery module receptacles and said electric motor, said power mode selector device having; a series electrical orientation for electrically connecting two or more battery module receptacles in series to said electrical motor, a parallel electrical orientation for electrically connecting two or more battery module receptacles in parallel to said electric motor, and an individual electrical orientation for electrically connecting one of said battery module receptacles to said electric motor; and whereby said power mode selector can selectively connect one, two or more of said battery module receptacles to said electric motor in one of either said series electrical orientation, said parallel electrical orientation, or coupled individually with said electric motor. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

21. An electric vehicle and charging method therefor, comprising the steps of:
-
obtaining an electric vehicle comprising; two or more battery module receptacles and an electric motor, each said battery module receptacle defined by a power coupling for electrically connecting a battery module in a said receptacle to said electric motor; a power mode selector device electrically connected between said two or more power couplings and said electric motor, said power mode selector device having; a series electrical orientation for electrically connecting two or more power couplings in series to said electrical motor, a parallel electrical orientation for electrically connecting two or more power couplings in parallel to said electric motor, and an individual electrical orientation for electrically connecting one of said power couplings to said electric motor; and whereby said power mode selector can selectively connect one, two or more of said power couplings to said electric motor in one of either said series electrical orientation, said parallel electrical orientation, or coupled individually with said electric motor; obtaining one or more battery modules cooperatively designed to interface with said receptacles and said power couplings; installing one or more said battery modules into said receptacles and connecting to said one or more power couplings; removing one or more said installed battery modules and replacing each said removed battery module with a charged said battery module; and measuring the electrical charge remaining in said removed modules and responsively assigning a net charge value used for each said removed battery module. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
