Sadly, you need more than the female socket. J1772 is like 90% scam to enable charging people money to charge an EV, and 10% about charging EVs. It doesn't enable until the station is satisfied, and then the communication with the vehicle says it's OK to turn-on.
Safety
The J1772 standard includes several levels of shock protection, ensuring the safety of charging even in wet conditions. Physically, the connection pins are isolated on the interior of the connector when mated, ensuring no physical access to those pins. When not mated, J1772 connectors have no voltage at the pins,[13] and charging power does not flow until commanded by the vehicle.[12]
The pins are of the first-make, last-break variety. So that if the plug is in the charging port of the vehicle and charging, and it is removed, the Control Pilot and Proximity Detection pins will break first so that the Power Pin relay in the Charging Station will be shut off and no current will flow.
[edit]Signaling[12]
Supply equipment signals presence of AC input power
Vehicle detects plug via proximity circuit (thus the vehicle can prevent driving away while connected)
Control pilot functions begin
Supply equipment detects plug-in electric vehicle
Supply equipment indicates to PEV readiness to supply energy
PEV ventilation requirements are determined
Supply equipment current capacity provided to PEV
PEV commands energy flow
PEV and supply equipment continuously monitor continuity of safety ground
Charge continues as determined by PEV
Charge may be interrupted by disconnecting the plug from the vehicle
In a future development of the standard due in 2012, SAE proposes to use power line communication between the vehicle, off-board charging station, and the smart grid, without requiring an additional pin; SAE and the IEEE Standards Association are sharing their draft standards related to the smart grid and vehicle electrification.[14]

I can appreciate 10 - 15 min charges, but I'm afraid to ask the price and weight of that power supply! :lol:
