Lots of summer road trips - how to maximize

I have a LR AWD Y arriving on Monday, 142xxx vin. Very excited and have been ogling Teslas for almost a decade of Volvo driving. I work in the summer camp industry and therefore, have a lot of driving to do May-August from downstate NY to upstate (Adirondacks, Catskills and Poconos). At our office / home, there is a home charger my coworker uses to charge his X and we'll be sharing. At each camp, there will obviously be 110 and possibly some 240 outlets depending on location I can park. At each camp, when I go, I usually stay for a few days and barely go anywhere so even 110 will be fine. The typical routes are about 200 miles each way. Depending on trip, there are between 3 and 8 super chargers between the various destinations. So I don't completely trash my battery this summer, what's the best plan of attack here?

The most logical, cost efficient and battery degradation saving thing to do would seem to be to supercharge as little as possible and charge at the place where you'll be staying for several days, if you know for sure that you'll have access to plugging in at all those locations... Not an expert, but it would seem to be the best way to go.

If you're positive there will be power available at the camps, that's where I would be doing the bulk of my charging. If there's 240v, I would try to find out which receptacle it is and then pickup the appropriate Tesla mobile connector AC adapter(s).

For sure there will be 110 so if I'm there for 4-7 days, who cares how long it takes right? 240 will be most likely next to an industrial building like kitchen, laundry, etc. I know it says not to use an extension cord but if it's a proper gauge and high quality, we should be ok?

Yes, you can fully charge from empty in about 3 days on 110v @ 15A. You can use an extension cord, but you may need to reduce the amperage in order to keep plug/cord/breaker temps from getting too hot.

You should assemble a charging kit that you can rely on for charging at the summer camp locations. Start with the Tesla Mobile Connector kit that comes with the Tesla vehicle. The kit includes a NEMA 5-15 power plug adapter. That will work with any grounded 15 amp or 20 amp 120V outlet. If you want add to the kit then consider a NEMA 5-20 power plug adapter.

You can purchase additional power plug adapters for the Tesla Mobile Connector from the Tesla Store (either individually or as a set.) True RV campgrounds commonly offer a 30 amp receptacle known as a Travel Trailer 30A (TT-30), a 120V, 30 amp outlet. Tesla does not sell a TT-30 adapter but this can be purchased from EVSEadapters.com.

You will want to add a contractor grade three prong extension cord, or several. A shorter cord, up to 50 ft. can be 12 or 14 gauge. If you also decide to bring a longer extension cord, up to 100 ft., it should be 10 gauge or 12 gauge. Only use an extension cord if needed, use the shortest length extension cord that can reach the electrical outlet. Do not daisy chain the extension cords together.

Tesla provides a table that can give you an estimate of how many miles of EV range are added per hour of charging with each type of 120V or 240V circuit when using the Tesla Mobile Connector. Gen 2 NEMA Adapters

The Tesla vehicle also comes with a Tesla J1772 charging adapter so you can use any Level 1 or Level 2 charging station (some require an account, others are free.) Download the Plugshare app onto your phone to locate public charging stations near your location. Use A Better Route Planner on your phone or on the web to help plan your trips, determine charging locations.

I would use the Tesla Supercharger network when you need to charge on the road. Although using the Supercharger network will cost perhaps $0.30 per kWh (some places a bit more or a bit less) using a Supercharger will save you time. I would not be concerned about the Tesla's battery pack when Supercharging. The Tesla vehicle will manage the charging session to protect the battery pack.

@jcanoe thank you for the detailed explanation! During my first trip(s) of the season to each camp in May, I will scout out plugs, cord distances, etc and purchase appropriately.
Be aware that you must have a proper grounded outlet to be able to charge. Pick up a small outlet tester for under $10 on Amazon, this will diagnose common wiring issues. One like this: https://www.amazon.com/Gardner-Bend...&keywords=outlet+tester&qid=1615599529&sr=8-9

Also, outlets that are more than 5 years old, especially if they are outdoor outlets should be replaced as they get corroded, wear out and then don't make a tight connection with the plug. (Every camp has a handyperson/caretaker as I recall. Find out what the caretaker likes to drink. Ask them to change the receptacle for you once you figure out where you can plug in.) Use only a commercial grade or hospital grade receptacle. These come packaged not loose in a bin at the big box hardware store or electrical supply store.

The Tesla Mobile Connector chassis is not designed for all weather use. Try and keep the Mobile Connector chassis (the electronics unit) dry and off of the ground. Even placing the chassis on a brick or cinder block is better than leaving the Mobile Connector chassis on the ground. This will only be an issue if you use an extension cord because the Tesla power plug adapter is only 1 ft. long. Bring along one or two short bungee cords, some velcro tape or similar. You will want to hang the Mobile Connector chassis from a nail, hook etc. to support the Mobile Connector chassis so it does not hang supported only by the plug and receptacle.

It sounds as if you have lots of time to charge, and plenty of charging opportunities otherwise. I wouldn't stress too much, or spend a bunch of money on extension cords and adapters.

It's likely worth buying a L14-50 plug set for the mobile connector for $35. Then, if needed, buy off-the-shelf adapters to L14-50 for anything else you encounter. You'll need to explicitly set a lower charge current, and it's not as convenient as buying the correct plug set from Tesla (which will signal the appropriate current limit and has a temperature sensor to detect overheating), but spending $35 for a one-time charge doesn't make sense.

I did a similar thing last year, in my first road trip with the Y. Our place in Maine is on an island, and we rent a boat from the local marina to get there. Made a deal with the owner to plug in and pay him for the electricity. There was a convenient 120V 15A outlet near the docks. Plugged the mobile connector right in, rented the boat, and headed off. Checked it every day from the app to make sure it was still charging. When the remnants of Hurricane Isaias came through, the GFCI on the outlet tripped and it stopped charging. I just reset it the next time I went to the car and it went back to charging. Took about 3-1/2 days to fully charge, and a day or so to recharge after local trips, but I never had to head to the nearby supercharger.

And the number of questions I got about the car! Everyone was curious, and I bet I got a few people thinking about EVs who hadn't been considering them. Also hopefully the marina is thinking about adding actual charging points. Most people just come for the weekend so level 1 is only semi-useful, but a few L2 chargers will be a big selling point in a few years. And they do have slips with shore power, so they know about providing electricity to customers.

First off, that's not even a typo, since you repeated it, but it's a brain lapse. The L means "locking", so those are the twist lock plugs. What you mean is just 14-50, not L14-50. But I don't really agree with this. We used to have to do that kind of hokey stuff years ago when there were few types of Tesla plugs available, and there weren't proper adapters that signaled the amps. Now we do have those.

And this doesn't even make sense. You're suggesting buying adapters for everything, but then say buying adapters doesn't make sense.

Just get the real proper adapters that signal the current. Anything that Tesla doesn't officially sell, you can get from EVSEAdapters.com.
