I’ll admit it. I was reluctant to buy a Tesla because I was worried about running out of “juice”. What if I was on a long trip and I couldn’t find a charging station? Gas stations are everywhere, but what about charging stations? Fortunately, my friend Laura showed me that my fears were baseless.
Sitting together in her Tesla S, she asked me to specify a destination, typed it into the “Navigate” box, and voila! The car mapped the route (in my example here, we are going from Central Jersey to Columbus, Ohio), showing recommended charging stops, estimated arrival times, and length of time it would take to charge to the recommended level. (Never charge to 100%, but we’ll get into that later). If you click on one of the route’s pins, up will pop information about that particular supercharger–how many stalls and which amenities are available.
The car’s Navigation system usually recommends Tesla Superchargers along the route, and so far, I have been unable to find a destination for which there are not sufficient Superchargers, but who knows? Maybe it is possible. And what if you want to plan out a long trip, but don’t want to do it while sitting in your car? Fear not, there are options.
Like the Tesla Navigation app in your car, the top three apps map out your route, providing recommended stops for charging, with information about the amenities offered per stop.
If you prefer using your computer rather than your phone, here ya go:
There are more–but these 6 apps should get you started and keep you busy for quite a while.
The bottom three icons are for different charging networks. Evgo and Chargepoint charging stations are open to everyone. You just need the correct connector. For the Supercharger network you need the correct car. If it isn’t a Teslas, you’re out of luck.
The last time I visited my family in Massachusetts, I only knew about the EVgo network, so I was pleased to see that there were 2 EvGo chargers closer than the nearest Tesla Supercharger. Boy, did I have a lot to learn.
Lesson #1: make sure you have a compatible adaptor. Doesn’t sound difficult, does it?
But wait: the options are CHAdeMO, CCS, J1772 and NEMA. Although your Tesla comes with this neat bag stashed in the trunk, it only contains the J1772 and NEMA adaptors. Guess what the EvGo network uses? If you chose “none of the above”, you’d be right.
The J1772 adaptor is on the right. On the left, you see what awaited me at the EvGo station. Sadly, it was impossible to “mate” these two, although, believe me, I tried.
Subsequently, I learned that the gadget on the left is know as a CCS connector, which unfortunately, isn’t available for Teslas yet. A bit of a bummer, given that CCS is becoming the USA standard. Tesla DOES offer an adaptor for use with CHAdeMO connectors, but it is bulky and costs $450. Because CHAdeMo is not the standard of the future, I’m hard pressed to plunk down that kind of money, especially since enough Superchargers are available, although sometimes I have to drive 5 or 10 minutes out of my way. On the bright side, Superchargers are located near food, bathrooms, shopping, wifi, AND the other Tesla owners I’ve met while charging are all so friendly and helpful.
Lesson #2: Research the different charging networks. After I discovered PlugShare and ChargePoint, I learned that there were several OTHER charging stations nearby that offered FREE level 1 charging, compatible with the J1772 adaptor.
Lesson #3: Learn about the different charging levels. Level 1 is the power you get when you plug into a standard home outlet, using a NEMA adaptor. This gives you a charge of 110 volts, which gets you about 8 to 15 miles worth of charge per hour.
Level 2 is 240 volts, which gets you approximately 124 miles in about 5 hours. The only way to charge faster is with DC, and that is what the superchargers use. (You need the CCS or CHAdeMO adaptor to access a non-Tesla DC supercharger).
I learned from my electrical engineer son that 240 volts is the maximum you can get for home charging, and let me tell you, it takes a WHOLE lot longer to charge at home than it does with supercharging, but who cares? At home, you can charge while you’re sleeping. At least that’s what I normally do.
I know you probably have heard more about charging than you want or need, but one last thing: Your Tesla will go from 20% to 50% a whole lot faster than from 50% to 80%. Keep that in mind if you are using a network where you pay by the MINUTE, not by the kWh or mile (that’s how EvGo does it).
Here’s a visual example. I decided to start 2021 with the battery fully charged. The computer estimated it would take six hours and thirty minutes to go from 29% to 100%. When I checked the progress on my iPhone this is what I discovered.
After four and a half hours, the battery was at 98%, and it was estimated it would take almost another hour for the last 2%. That explains why the Tesla trip planner suggests that you run the battery to low levels before stopping to charge, and it never recommends that you charge to the maximum. I found that puzzling, until my son explained that it was like Lucy and Ethyl at the chocolate factory. Initially they could stuff a lot of chocolates into their mouths, but as their mouths got full, the “stuffing” got slower. Or if you prefer, think about filling a container with water and how you slow down as the container gets full.
You’ll see the trip planner shown at the top of this post has you run your battery WAY down before charging, plus it doesn’t have you charge too much, so you minimize your time at charging stations. Of course, when I go on long distance drives, I look forward to bathroom, food and stretching breaks, so I sometimes stay longer than suggested at the charging stops–but that’s just a personal preference.
As you’ve probably guessed from this post, I am NOT technically oriented. If you are, and would like more in-depth discussions, check out the Tesla Motors Club (https://teslamotorsclub.com) forums.
I hope this information is helpful. Any tips anyone wants to share would be most welcome. Let’s all learn together!

Although it can sound complicated, it really isn’t once you learn it… or, like me, just charge at home and one other (free) station. I will be attending a Zoom meeting of our local EV Club next Wednesday that will be about the latest battery technology. I think electric cars will become more mainstream quickly as people learn about the pluses (of which there are many).
You are SO right. What initially seems complicated quickly becomes second nature.
I only use other chargers when I go on long trips, like to visit my family in Massachusetts. Otherwise I charge at home.
NJ is one of the only two states where you don’t pump your own gas. If I had to stand out in the cold and rain to fill ‘er up, I’d appreciate home charging even more than I already do.

Really… you can’t pump your own gas? I wonder why they have that law? Of course, as EV owners, we just smile and wave as we pass by pumps.
Thanks Shelley for the good summary! I have been meaning to upgrade my garage to a 240 V outlet, but I’ve done fine with my home 110V for the last 6 months. Granted I’m retired and its during COVID, but I’ve only needed to Super Charge it 3 times. I’ve mapped out some trips and I’m amazed at the number of Tesla charging stations. Love my car!!!
It’s so easy to charge overnight. And what difference does it makes if it takes 3 hours or 7 hours if you’re asleep anyway.
I am hoping that the federal government will encourage the production of more electric cars, which will result in more charging stations. THEN I would fee comfortable planning a cross country drive to visit our son. I know I could do it now, but I want the experience to be relaxing— and the route determined by the side trips we want to take, not where the charging stations are located.
