Square white box should be protected from water and direct exposure to hot ......rain.
Protect this and extension cable and J1772 adapter is water proof. So you can use it in the winter....snow....rain no issues....but don't try to wash EV and apply pressured water around the charging port. If it happens that is stuck frozen.....heat up cotton towel in the dryer and apply over the J1772 adapter and charging port. Wait for 5 minutes and see if you can brake it loose.
