The J1772™ Adapter box is used to connect an OEM Level II J1772™ EVSE, to a NEMA receptacle. If you have a 240vac charger in your EV and want to connect to a J1772™ charging station, you can use the J1772™ Adapter Box to charge your EV.
The Adapter Box contains a pilot signal generator that enables the 240vac in the EVSE.
Please note that Level II is 240vac only, not 120vac. All pin connections are crimped to Military Specs.
– We can also put a Security Handle on the side so that you can lock up the Adapter Box if needed.
- The pilot circut is contained in a Cantex 4x4x2 box with strain relief and mounting tabs,
- The EVSE needs to see 2 signals before it will initalize charging, the OFF position supplies one signal and the ON position supplies the 2nd signal to close the EVSE contactor so that power is supplied and the LED comes on.
- 3 ft of 10AWG 3 wire cord (for connection to a 240vac charger only), 2 hots and a ground.(8AWG available upon request).
- A switch for OFF/ON.
- OFF for when J1772™ is plugged in and not energized, LED off.
- ON for charging, LED is on.
- When charging is finished and you want to unplug, turn switch to OFF and unplug J1772™.
Our switch provides three functions:
The switch simulates the two states required by the J1772™ specification for connecting an EV to the EVSE: With the switch in the OFF position, it sends a signal to the EVSE that says ‘a car is plugged in and not ready to accept energy’. With the switch in the ON position, it sends a signal to the EVSE that ‘a car is plugged in and ready to accept energy’.
When the switch is in the OFF position, the ‘ready to charge’ pilot signal is not present. The EVSE will not close its power contacts or if closed the EVSE will open its power contacts when the ‘ready to charge’ pilot signal is not present or the Pilot signal is opened. Per the J1772™ standard, the pilot pins are shorter than the power and ground pins. When the plug is pulled from the car’s inlet the Pilot signal is interrupted first. Since the EVSE monitors the Pilot pin connection, the EVSE opens its power contacts to prevent arcing across the power pins. In addition, on a car that comples with the J1772™ Protocol (such the Nissian Leaf or Chevy Volt), the opening of the latch on the J1772™ Plug initiates a controlled shut down of the charger in the EV. When the plug is pulled from the car’s inlet there is no power circuit for the energy to flow; therefore, no arcing can occur on the connector power pins. This is a double safety to prevent opening the connection under load.
The switch can be used by the user to immediately initiate a shutoff of power to the vehicle from the EVSE, The user can turn the switch to the OFF position and the EVSE will open its power contacts thus interrupting the power to the vehicle.
