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.

Claims

1. A motor vehicle, comprising:

a chassis;

a propulsion system attached to said chassis, said propulsion system comprising an electric motor operatively connected to drive at least one drive wheel;

a battery module receptacle attached to said chassis, said battery module receptacle defined by two or more power couplings electrically connected to said propulsion system;

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 of said power couplings in series to said electrical motor,

a parallel electrical orientation for electrically connecting two or more of said 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;

wherein 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; and

two or more battery modules selected from a group of battery modules configured to be insertable into said battery module receptacle and removeable therefrom, each battery module establishing electrical connection to one of said power couplings when inserted, each said battery module being interchangable with another battery module from said group; and

wherein each battery module comprises a housing encasing a plurality of battery elements electrically interconnected to one another and to a module power coupling, said module power coupling cooperating with said battery module receptacle power coupling to electrically interconnect said power couplings when said module is inserted into said module receptacle, said housing further comprising a set of rollable wheels extending therefrom.

2. The motor vehicle of claim 1, wherein each said battery module is selected from a group of battery modules having a standard size.

3. The motor vehicle of claim 2, further comprising an internal recharging system for recharging each said battery module when said battery module is inserted into said module receptacle.

6. The motor vehicle of claim 1, wherein each battery module comprises a unique identity element associated therewith.

7. The motor vehicle of claim 6, wherein each said battery module comprises a module status element associated therewith.

8. The motor vehicle of claim 6, wherein each said battery module comprises a module status element associated therewith.

4. An electric vehicle and battery module supply system therefor, comprising:

an electrically-propelled vehicle having two or more exchangeable battery modules within a battery module receptacle attached to said vehicle, said vehicle further defined by;

a power mode selector device electrically connected between said two or more battery modules and said electric motor, said power mode selector device consisting essentially of;

a series electrical orientation for electrically connecting two or more of said battery modules in series to said electrical motor,

a parallel electrical orientation for electrically connecting two or more of said battery modules in parallel to said electric motor, and

an individual electrical orientation for electrically connecting one of said battery modules to said electric motor;

wherein said power mode selector can selectively connect said battery modules to said electric motor in either said series electrical orientation, said parallel electrical orientation, or said individual electrical orientation;

a pool of mobile battery modules cooperatively configured to be installable within said receptacles;

a plurality of module exchange stations for recharging and facilitating the removal and installation of said recharged battery modules within said vehicle said module exchange stations further configured to measure and record the amount of electrical charge remaining in each exchanged said battery module;

a battery module management system executed on a programmable computing system in communication with said module exchange stations to keep usage records of said battery modules; and

wherein said battery module management system tracks and computes the number of re-charging steps each said battery module within said pool experiences, and attributes said computed re-charging steps to an identified user to responsively attribute a usage cost to a user that is dependent upon the amount of charge transferred from each said module exchange station to said attributed user, said amount of charge transferred equaling the charge value of a newly installed recharged battery module minus the electrical charge remaining in said exchanged battery module; and

wherein each battery module comprises a housing encasing a plurality of battery elements electrically interconnected to one another and to a module power coupling, said module power coupling cooperating with said battery module receptacle power coupling to electrically interconnect said power couplings when said module is inserted into said module receptacle, said housing further comprising a set of rollable wheels extending therefrom.

5. The electric vehicle and battery module supply system therefor of claim 4, wherein said electric vehicle further comprises an internal recharging system for recharging each said battery module when said battery module is inserted into said module receptacle.

9. The electric vehicle and battery module supply system therefor of claim 4, wherein each battery module comprises a module status element associated therewith.

10. The electric vehicle and battery module supply system therefor of claim 9, wherein each said battery module comprises a module status element associated therewith.
