Ice Covered Plug in Handle

Does anyone have a suggestion for owners of a PHEV who park their vehicle outside in the elements?. This morning after the snow/ice storm it took me about 5 minutes to carefully chip away all the ice off the plug in handle.to be able to even disengage the charger from the car. Same type of thing happens when it snows. The snow fills the cavity around the plug. I would have thought there would be a sleeve I could buy to cover this. Alas I may have to jury rig something.
