Abstract

An electric vehicle supply equipment may include a first cover element including a well portion to accommodate a first circuitry, wherein the first circuitry includes a chimney stack that couples to a venting hole. Also, the electric vehicle supply equipment may include a second cover element including a recess portion to accommodate a second circuitry, wherein the second circuitry includes a charcoal filter that couples to the chimney stack to absorb impurities generated by the first circuitry and the second circuitry. Further, the electric vehicle supply equipment includes a universal/serial connection port configured to couple to peripheral devices, wherein the universal/serial connection port is an optical coupled connection.

Claims

1. An electric vehicle supply equipment comprising:

a first cover element comprising a well portion to accommodate a first circuitry;

a chimney stack disposed on the first circuitry that corresponds to a venting hole, the chimney stack facilitates a flow of gasses;

a second cover element comprising a recess portion to accommodate a second circuitry;

a charcoal filter disposed on the second circuitry that corresponds to the chimney stack, the charcoal filter absorbs impurities generated by the first circuitry and the second circuitry; and

a universal/serial connection port configured to couple to peripheral devices, wherein the universal/serial connection port is an optical coupled connection, wherein the first or second circuitry includes a voltage regulator having a first low voltage and a second higher voltage to move a relay.

2. The electric vehicle supply equipment of claim 1, wherein the well portion and the recess portion are filled with potting material to encapsulate the first circuitry and the second circuitry.

3. The electric vehicle supply equipment of claim 1, wherein the first cover element and the second cover element are constructed to meet NEMA 4X standards.

4. The electric vehicle supply equipment of claim 1, wherein the optical coupled connection is an isolating reverse parallel optical connection.

5. The electric vehicle supply equipment of claim 1 further comprising a water proof connector.

6. The electric vehicle supply equipment of claim 4, wherein the isolating reverse parallel optical connection is configured to shut off or derating a maximum amperage of the peripheral devices.

7. An electric vehicle supply equipment comprising:

a first cover element having a well portion that accommodates a first circuitry;

a chimney stack disposed on the first circuitry that corresponds to a venting hole on the first cover element, the chimney stack facilitates a flow of gasses that are generated during use of the electric vehicle supply equipment;

a second cover element comprising a recess portion to accommodate a second circuitry;

a charcoal filter disposed on the second circuitry that corresponds to the chimney stack, the charcoal filter absorbs impurities generated by the first circuitry and the second circuitry;

a universal/serial connection port configured to couple to peripheral devices, wherein the universal/serial connection port is an optical coupled connection;

a control circuit that passes signals representing a voltage on an electrical conduit to a processor that controls a relay; and

a voltage regulator that provides additional voltage levels to operate the relay, wherein the additional voltage levels include a first low voltage for maintaining the relay in a first position and a second higher voltage for moving the relay to a second position.

8. The electric vehicle supply equipment of claim 7, wherein the well portion and the recess portion are partially filled with a potting material to encapsulate portions of the first circuitry and the second circuitry.

9. The electric vehicle supply equipment of claim 7, wherein the first cover element and the second cover element are constructed to meet NEMA 4X standards.

10. The electric vehicle supply equipment of claim 7, wherein the optical coupled connection is an isolating reverse parallel optical connection.

11. The electric vehicle supply equipment of claim 7 further comprising a water proof connector.

12. The electric vehicle supply equipment of claim 10, wherein the isolating reverse parallel optical connection is configured to shut off or derating a maximum amperage of the peripheral devices.
