Transformer and electric vehicle charger combination
A transformer and electric vehicle charger combination has a charging box with a first hollow interior and a transformer box with a second hollow interior. A DC charger is positioned within the first hollow interior and a transformer is positioned within the second hollow interior. The DC charger is electrically connected to the transformer such that electricity from the transformer is supplied to the DC charger. At least one charging cord has a first end and a second end. The first end is in electrical communication with the DC charger. The second end of the charging cord has an electric connector for plugging into an electric vehicle charging port.
1 . A transformer and electric vehicle charger combination, comprising:
a charging box having a first hollow interior, a DC charger being positioned within the first hollow interior;
a transformer box having a second hollow interior, the transformer box having a high voltage utility connection, the charging box being attachable to the transformer box such that the charging box and the transformer box are positioned together in a single location, an electrical transformer being positioned within the second hollow interior, the electrical transformer having at least one dedicated winding to serve the DC charger and at least one additional winding for supplying electricity for other purposes, the DC charger being electrically connected to the dedicated winding of the transformer such that electricity from the transformer is supplied to the DC charger;
at least one charging cord having a first end and a second end, the first end being in electrical communication with the DC charger and the second end having an electric connector for plugging into an electric vehicle charging port; and
a central computer, the central computer controlling the flow of electricity from the electrical transformer to the DC charger and to the at least one charging cord such that when authorized the central computer allows a current to pass from the DC charger to the electric connector and when not authorized the central computer prevents the current from passing from the DC charger to the electric connector.
2 . The transformer and electric vehicle charger combination of claim 1 wherein the charging box has at least one access door to provide access to the first hollow interior.
3 . The transformer and electric vehicle charger combination of claim 1 wherein the transformer box has at least one access door to provide access to the second hollow interior.
4 . The transformer and electric vehicle charger combination of claim 1 wherein a gasket is positioned between the charging box and the transformer box to provide sealing against moisture ingress between the charging box and the transformer box.
5 . The transformer and electric vehicle charger combination of claim 2 wherein a charging box door gasket is positioned on the at least one access door to provide sealing against moisture ingress into the first hollow interior between the at least one access door and the charging box.
6 . The transformer and electric vehicle charger combination of claim 3 wherein a transformer box door gasket is positioned on the at least one access door to provide sealing against moisture ingress into the second hollow interior between the at least one access door and the transformer box.
7 . The transformer and electric vehicle charger combination of claim 1 wherein a payment authorization system is provided, the payment authorization system being connected to the central computer such that an authorized payment causes the central computer to allow a DC current to pass from the DC charger to the electric connector, the central computer preventing the DC current from passing from the DC charger to the electric connector when no authorized payment is made.
8 . The transformer and electric vehicle charger combination of claim 7 wherein a screen is positioned on the enclosure, the screen providing information about at least one of output readings, payment information, purchase options, charge status, estimated finishing time, or electricity rates.
9 . The transformer and electric vehicle charger combination of claim 1 wherein the at least one charging cord has a breakaway fitting to allow for breakaway of the charging cord at a predetermined force threshold.
10 . The transformer and electric vehicle charger combination of claim 9 wherein breakaway of the charging cord at the predetermined force threshold causes shutdown of the flow of electricity from the DC charger.
11 . The transformer and electric vehicle charger combination of claim 1 wherein an emergency stop is provided in communication with the central computer such that activation of the emergency stop terminates the transfer of electricity from the DC charger to the at least one charging cord.
12 . The transformer and electric vehicle charger combination of claim 1 wherein the transformer has at least one dedicated output for the DC charger and at least one dedicated output for supplying electricity for an additional use, the at least one dedicated outputs for the DC charger and the at least one dedicated output for supplying electricity for an additional use having an overcurrent protection, and each of the dedicated outputs for the DC charger and the at least one dedicated output for supplying electricity for an additional use being supplied by a single utility feeder connection.
13 . The transformer and electric vehicle charger combination of claim 1 wherein the charging box is positioned on a top of the transformer box.
14 . The transformer and electric vehicle charger combination of claim 1 wherein the transformer box is positioned on a concrete pad mount.
15 . The transformer and electric vehicle charger combination of claim 1 wherein the first hollow interior and the second hollow interior are integrally formed.
