The part you are checking has no power coming out, it's an input that's only ever energized while an EVSE is plugged in and charging. If you're just trying to check those fuses you don't actually have to remove anything. The cable runs from the port, through the inner fender, and connects to the rest of the harness under the hood. The connector is between the fuse box and the headlight. It has a two step latch where you remove a nylon "tool" from under the catch and then push it through the top to lift the catch. Once that's done the connector can be pulled apart.
From there, you want to use a multimeter to test continuity. Alligator clips or some extra bits of wire will make it easier to maintain contact with the pins. Put one lead on either of the larger pins on the charge port, then look for continuity with one of the larger pins in the connector. If each has continuity to one of the harness pins, the fuses aren't a problem and you may need to go further down the harness to the onboard charger. If either doesn't have continuity, and you're certain the leads are making contact, you'll want to pull the fender liner and check the fuses.
Jack it up, use a torx on all the metal fasteners, gently pull the plastic caps up on the others so they can be pulled out, then the liner can be pulled out.
From there the fuse cases should be obvious, though they might have foam bumpers on them. You'll also want to inspect for any other damage to the wiring.
