I think their are some potential points when charging with level 1 with a big extension cord from the garage (likely more common than residential level 2 for Aptera). The charge door when open and adapter needs to be correctly designed (which id expect) and chaining extension cords isn’t great. For outdoor charging it would be best to have a large gauge well made extension cord. Don’t charge an ev with a piece of junk 16 gauge cord from walmart.
EVSEs are waterproof and they have built in protections against any sort of mishap, in fact their whole purpose is to act as a fancy circuit breaker, the charger is in the car not the EVSE. You will want to get a good one, I have a ClipperCreek and a Tesla. Obviously you should only buy a UL listed and outdoor rated EVSE but as long as you do then no worries.
Yes, Aptera will have windshield wipers. And air conditioning. And heat. And some form of airbags. And the lower half of the door windows will roll up and down. Remember that the three vehicles you’ve seen are just prototypes – they’re nowhere near the final product.
