1. A charging system for charging electric vehicle batteries using electrical power supplied to public fixtures by power mains, said system comprising;

  • a. a charging station including a power interface module connectable to power mains conductors fed into a public fixture, said power interface module including a keyed receptacle for conducting electrical power from said power mains to a complementarily keyed plug insertable into said receptacle,b. an electric vehicle battery charger cable terminated at an input end thereof by a plug keyed complementarily to said keyed receptacle, andc. a vehicle charge control system, said vehicle charge control system including,i. a pre-paid charge authorization payment device having a money balance,ii. a charging station access enable device responsive to a money balance in said payment device in providing on a control signal output port thereof a charging station access enable signal, said charging station access enable device being responsive to an input signal on in input signal port thereof an input signal proportional to the quantity of consumed electrical energy measured by an electrical energy consumption measurement device in deducting from said money balance an amount proportional to said consumed electrical energy, said access enable device providing on said control signal output port thereof an access enable signal for as long as said money balance is greater than zero,iii. at least a first current conducting contactor having a first contactt port connected to an output load end of said vehicle charger cable, a second contact port connected to a charging current regulating apparatus effective in inputting charging current to batteries within an electrical vehicle, and a control signal input port connected to said control signal output port of said charging station access enable device, said contactor effecting electrically conductive contact between said first and second contact ports as long as a money balance remains on said pre-paid charge authorization payment device, andiv. an electrical energy consumption measurement device for measuring consumption of electricity used in charging batteries of a vehicle, said measurement device being connected in series with said contactor and said charging current regulating apparatus and having a signal output port on which occurs a signal proportional to consumed electric energy, said signal output port being operatively interconnected to said input port of said access enable device and thereby effecting decrementing a money balance on said pre-paid charge authorization payment device a money amount equal to the product of electrical energy consumed times a predetermined cost per unit of electrical energy.
