A user can approach an outlet station in an electric car, plug the car into the station similar to using a gasoline pump, present a credit card to the system, and be provided with either standard line voltage of sufficient wattage to charge the battery of an electric or hybrid vehicle. After the vehicle is charged, the credit card debited for the correct amount for the power dispensed, or other arrangements to pay can be accommodated such as debiting a prepaid account. Optionally, the user can also inject (100) reverse-flow power back into the grid for credit and receive credit for the power injected. Several users can share the same station, and can identify themselves by key access, card swipe, biometrically, or by a card containing an RFID chip that contains their identity. ## Claims ### Claim 1 An electric vehicle charging device comprising: a power source a power metering device in electrical communication with said power source; a power switch in series with said power source; a processor in communication with said power metering device and said power switch; a credit card swipe device; wherein said power switch allows power dispensing to a user from said power source in order to charge an electric vehicle when said user has swiped a valid credit card, and wherein said processor charges said credit card for electric power dispensed; and wherein said user can inject reverse flow electrical energy into said charging device and receive credit for said reverse flow electricity. ### Claim 2 (depends on 1) The electric vehicle charging device of claim 1 further comprising a communication module connected to said processor wherein said communication module communicates over a network with a remote computer. ### Claim 3 (depends on 1) The electric vehicle charging device of claim 1 further comprising a user identification device. ### Claim 4 (depends on 3) The electric vehicle charging device of claim 3 wherein said user identification device contains an RFID reader. ### Claim 5 (depends on 3) The electric vehicle charging device of claim 3 wherein said user identification device is biometric. ### Claim 6 (depends on 1) The electric vehicle charging device of claim 1 further comprising a keypad. ### Claim 7 (depends on 1) The electric vehicle charging device of claim 1 further comprising a monitor connected to said processor. ### Claim 8 (depends on 1) The electric vehicle charging device of claim 1 wherein said user is charged according to dynamic electric power rates. ### Claim 9 An electric vehicle charging device comprising: a power source a power metering device in electrical communication with said power source; a power switch in series with said power source; a processor in communication with said power metering device and said power switch; a user identification device connected to said processor; a communication module connected to said processor wherein said communication module allows said processor to communicate with a remote computer; wherein upon command from said processor, said power switch allows power dispensing to a user from said power source in order to charge an electric vehicle when said user has presented proper identification to said user identification device, wherein said processor charges said user for electric power dispensed and wherein said processor can delay charging for either a fixed period of time or until a particular dynamic electrical rate is reached; and wherein said user can inject reverse flow power back into said charging device and receive credit for this reverse flow power. ### Claim 10 (depends on 9) The electric vehicle charging device of claim 9 further comprising a credit card swipe connected to said processor. ### Claim 11 (depends on 9) The electric vehicle charging device of claim 9 further comprising a keypad. ### Claim 12 (depends on 9) The electric vehicle charging device of claim 9 wherein said user identification device contains an RFID reader. ### Claim 13 (depends on 9) The electric vehicle charging device of claim 9 wherein said user identification device is biometric. ### Claim 14 (depends on 9) The electric vehicle charging device of claim 9 further comprising a monitor connected to said processor. ### Claim 15 (depends on 9) The electric vehicle charging device of claim 9 wherein said remote computer communicates over a network with other electric vehicle charging devices. ### Claim 16 An electric vehicle charging device comprising: a power source a power metering device in electrical communication with said power source; a power switch in series with said power source; a processor in communication with said power metering device and said power switch; a credit card swipe connected to said processor; a communication module connected to said processor wherein said communication module allows said processor to communicate with a remote computer; and wherein upon command from said processor, said power switch allows power dispensing to a user from said power source in order to charge an electric vehicle when said user has presented a valid credit card, and wherein said processor charges said credit card for electric power dispensed; and wherein said remote computer communicates over a network with other electric vehicle charging devices; and wherein said user can inject reverse flow power back into said charging device and receive credit for this reverse flow power. ### Claim 17 (depends on 16) The electric vehicle charging device of claim 16 wherein said user identification device contains an RFID reader. ### Claim 18 (depends on 16) The electric vehicle charging device of claim 16 further comprising a monitor connected to said processor.
