Yes, most all EVSEs have a ground check safety feature. To bypass this temporarily: Take a screw-on plug (NEMA 5-15P) and install two 1 watt 100k ohm resistors. One from neutral (silver screw) to ground (green), and the other from hot (gold screw) to ground (green). Then simply plug this into one outlet on the generator/power station, and your EVSE into the other. This will safely pass the ground detect on the EVSE, while not being a hazard in any other way. You definitely don't want a "hard bond" to one side without a proper ground rod.
