We specialize in J1772 Plugs, Inlets, wire and cords to connect them. We've been importing and selling Dostar products since the 2010 Revised J1772 Spec was released. Rush started TucsonEV when he was president of Tucson Electric Vehicle Club 2 by getting a couple of Inlets so the members who had conversions would be able to use the 200+ Level II EVSE's that were supposed to be installed in Tucson. We sell to individuals and companies that use the J1772 Plugs and Inlets in their production EV's and Hybrids

We opened TucsonEV in late 2010 and started to sell J1772 Plugs and Inlets.

In 2011 we developed the J1772 Adapter Box so that people with conversions could use the EVSE's. We also consulted with Dostar to finalize the Proximity circuit that is presently in their J1772 Plug.

In 2012 we introduced the J1772 Extension cord because we saw the need for a longer cord so that people who were 'iced' could charge their EV's

In 2013 we started production on a 30A EVSE, the TucsonEV-SE. It is designed and manufactured by us in Tucson. We are working on a 40A version with a true 8 AWG cord that can be over 50ft with about a 1% voltage drop on a 40A 240VAC circuit.

Here are our products. Shipping is not included.

Please note that all the power and ground connections to the pins in the plug and inlet are crimped with an industrial crimper to Mil Spec standards. The crimper exerts a 11-ton force and does a four barrel crimp.

J1772™ Adapter Box

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.

J1772 Adapter with label

- 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:
First Function:
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'.
Second Function:
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.
Third Function:
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.

J1772™ Adapter with remote Pilot Box

Pilot Box

This is an alternative to the J1772™ Adapter Box. It has the same specs, switch and LED as the J1772™ Adapter Box but without the 4x4x2 Cantex Box. The Pilot Signal generator is in a seperate box on an 18" cord so that the Inlet can be installed in the 'gas cap' area and the switch in another location. All pin connections are crimped to Military Specs.

Templates

Installation is simple -

  • Holes are drilled for the J1772™ Plug using a supplied Template.
  • Then the Pilot Box hole is made by filing out the template of the Template for Pilot Box which is superimposed over the J1772™ Plug.
  • The 4 hex bolts and nuts are removed from the 4 holes holding the Plug and Strain Relief together, DO NOT seperate them.
  • The 10 AWG cord is put thru the hole and then the Pilot box is put thru and the Inlet is then screwed into place using the 4 hex bolts and nuts.
  • The Pilot Box can be attached in an appropiate location in the trunk and the 10AWG cord is attached to the charger (8AWG available upon request).
