I am looking into buying a model s but I don't currently have a garage and live in Iowa where it rains and snows a lot. Is it safe to have a 50 amp outlet out side ans charge from it in the rain or snow
There are 25 or 30 thousand RV parks that each have anywhere from fifty to 200, 50 amp connections. There are also thousands of marinas that have hundreds of connections on the docks.
Being done without problems (must be proper outdoor receptacle properly installed).
Please note that the Mobile Connector manual specifically recommends against charging in the rain:
"Do not use the Mobile Connector when either you, the vehicle or the Mobile Connector is exposed to severe rain, snow, electrical storm or other inclement weather."
While first responders do not need to worry, because there is no return path, people handling charger wires may well have a return path for mains electricity. But electrical codes seem to have solved that problem.
@wcalvin, what? I can usually decipher what people are trying to say, but I can't figure out what you are saying there.
wcalvin, what u wrote doesn't make sense.
The shock hazard requires a current path through the body in excess of 10 milliamps. (Detection threshold is 1 ma.)
A battery that is not being charged, and is isolated from the ground you are standing on, presents no hazard if you merely touch one side of the battery. That's why they tell emergency responders not to worry: there is no likely current path that will pass through one's body.
If the EV is being charged, however, there is a shock hazard from the charger cable--not a big one as there are all sorts of interlocks. Unless you have done a DIY electrical installation that didn't follow code, there is little shock hazard even if you are standing in a puddle of water, viz the safety of marina installations.
And before someone throws up capacitative touch screens as an example of no return path, these are not milliamp currents. They are more like nanoamp currents and very brief. If you add a capacitative load to a circuit by touching it with something that conducts (a real finger nail will do, but not many plastic ones), a brief current flows that can now be detected. Depends on the surface area of what is attached, this being a Faraday cage. So embedding a conductive screen mesh in driving gloves will do the job. So will licking the glove fingertip first.
