Supercharger for Yosemite?

Seems like a high volume destination for Tesla owners. Any chance? And if the Park Service won't approve it, then Mariposa would be second choice.

Superchargers are located next to highways to allow us to get to our destinations. Once we are at a destination like Yosemite, we should charge overnight at our lodging facility. There's no need for an expensive Supercharger for overnight charging.

Right. The Slurp and Sleep System.

Nah, fast and quick everywhere, no compromise, no excuses, no extension cords out of your room's window. The quicker this sort of thing goes away, the better.

Can Yosemite infrastructure support a SC? Yosemite has no RV parks. I definitely don't want to see a large solar installation in Yosemite.
Mariposa is 50 miles away - that should be close enough to get in and out.
For some reason the 99 is empty in the SC plan... and that makes it hard to reach the Sierra Nevada parks. Elon and his planners do not have time to go to mountains I guess.

@Kleist, I agree that Highway 99 could use one or more SCs. I'll be taking a 175 mile trip in my S85 today from the SF Bay Area to Fresno, on Highway 99. A SC would help. Though for this trip, it would have been nice to find a hotel in Fresno with 240V charging. The only hotel I found in Fresno with EV charging offers 110V. My car will spend tonight charging at an RV park, so I can drive home tomorrow night.

Sounds like great location to use geothermal.

I just did a trip to Yosemite. The only way this was feasible was that we had rented a house and was able to use the dryer plug for charging overnight (note that i took a chance on this and did not know if I would be able to reach the dryer plug in the rental house). Without this it would have been a very limited trip.

Thus, I think a SC in the Yosemite area is a must. It would eliminate a lot of anxiety about going to Yosemite in a MS.

That is a good idea to rent a house with dryer plug and use it as the homebase for (any) national park.

What makes me wonder that 395 has SC in the final plan, but not 99 - 99 is a highly traveled road. Not that Californians should complain about SC, but we can voice our ideas and suggestions. Hopefully in a couple of years they will ban ICEs from Yosemite, but EVs need to be able to get there first.

The problem is the Yosemite Valley is 150 to 160 miles from the existing (and planned) Superchargers and one really would like to top up before driving into the Park. There is currently one 1772 in the Village and rumors of another. As for the town of Mariposa (I live outside of town near the Park), I have been talking with the motel managers about adding 14-50 and Board of Supervisors about land for a Supercharger. The issue is that one would like the Supercharger to be near the downtown restaurants and there is limited parking in the downtown area. Last thing we need is to have 4 or 8 prime parking spaces "reserved for EVs" in a town with limited parking already. There is interest, but getting the details right is critical. A SC in Merced is another good idea that would also serve the 99 corridor that we often drive.

shs - what about the restaurant at the 49/140 intersection? Seem to have a large parking lot as far as I remember.

The owner of the cafe/grocery store on that corner is expanding his store and willing to put in a charger of some sort, likely a 30 amp. There is lots of parking there and when I was discussing this with a Supervisor on Saturday, this is one of the sites that came up. It is privately owned and we were hoping to find a suitable county owned site closer to the center of town, but that intersection would certainly work. I will continue to pursue.

Also at the admin facility in El Portal, the Park has a large solar installation and two ancient paddle charging stations. I as also trying to get those changed to 1772 (a cord set is all that is needed), but there is nothing to do there while charging.

In the mean time, there is my garage... It won't be the first time for a visiting Tesla on its way to Yosemite!

shs - thanks for your effort and activities around Yosemite. Every journey starts with the first little step. This autumn I'll bring my MS to Yosemite - the more we show up the better. How I will do it... probably rent a house with dryer plug or tent at a RV park.

There is one motel in Mariposa, the River Rock, with an L6-30 outlet for EVs. I have tried to talk the owner into changing it to a 10-30 or 14-30 so people can use a supported Tesla adaptor, but no luck. "Take if or leave it", is her attitude . I have an L6-30 to 10-30 adaptor if needed by anyone. By autumn, I hope that several of the other motels have a 14-50 for EVs, but only time will tell. Or better yet, a supercharger in town!

When I suggested in a Letter to the Editor in a local newspaper that EV charging might be a lure to get more people to town, the most constructive comment I got, was to also install tie-downs for dirigibles, as we will probably get as many of those as EVs. The more people that call the local motels and ask about charging the better. Or the tourism bureau, although they seem to be on board.

dirigibles - funny, but not far off... I am floating on air ( suspension ). So simply more "dirigibles" need to show up.

Now there's a challenge! How many owners here would certainly visit Yosemite in the next 2 years if there were adequate touring and sleep-over charging locally?

Brian - bingo!
How can we make e.g. Mariposa a base camp for Yosemite EV tourism? Perfect location for day trips in and around the valley - we just need to be able to recharge overnight.
I know Yosemite as long as I am in the US, but mostly from the packback country. Valley car tourism is new to me. My idea is the inlaws (in their seventies) have never been to Yosemite, long walking or camping is not an option and so a hotel/motel is a must... check out first with my wife the options and then later bring the inlaws. Actually I am more concered about them getting altitude sick then the EV trip challenge.
With about 2 billion ICEs on Earth... a stinker free Yosemite is the end goal, but unlikely in my lifetime. Just get a start... every single vist counts.

Reading this forum is so funny. As a former resident of the Central Valley, I can anticipate Fresno/Yosemite will be the last place a SC station will be set up. Nothing important happens in the CV. Realistically, it is much farther away from SF, LA or Sacramento than the map shows.

The answer to our woes will be a portable solar charger panel on the roof of our TESLA's so we will charge as we go, or the option to change our batteries ourselves so we don't need SC stations.

Old nonsense. Grossly insufficient for about 5 different reasons.

I do not own a Tesla yet, but am very interested. One of my big concerns is its range for getting to Sierra backpacking and northern California river trips. It looks to me as if even the planned Supercharger rollout is mainly for more urban and inter-urban driving.

Taking this thread as an example, even a Supercharger in Mariposa looks dodgy to me. If I want to take visiting relatives to Yosemite Valley, up to Glacier point, around to Tuolumne Meadows, and back Google maps says the Mariposa-to-Mariposa mileage is 236 miles. And that does not count any incidental driving, such as to trailheads or just touristing around, that we would do. It also does not allow for overnight parasitic drain (which I have read is about 15 miles per night) -- a significant amount if we are in the park for several days.

Recharging in the park seems essential, but any nights we spend in the park would be in tents -- either at a campground or backpacking -- so I'm not clear how I would recharge in the park.

Another concern is getting to trailheads on the Sierra east side. I have the impression that there are plans for Superchargers on Route 395, somewhere between Mt Whitney and Reno, but I have not been able to find any details. Some Supercharger capability along Route 395 seems necessary, at least until we can recharge at trailheads :)

Are others using their Model S's for things like Sierra backpacking, Trinity Mountains backpacking, or northern California river trips? If so, how do you handle the charging?

My bottom line is that I can see the Tesla Model S (and, presumably the Model X) as practical for most things, at least once the other Superchargers get rolled out, but I am having a difficult time seeing it as practical for getting to wilderness outings.


City to city will soon be possible. National park to national park isn't even discussed. I would love to be able to take my Model S across the country to visit national parks, but it is virtually impossible. A supercharger near each major park would be great, or alternatively, many J1772 chargers in the parks near trail heads. Hopefully, the increasing volume of electric cars will enable this within a few years.

There is very little charging infrastructure in the central valley. Somewhere along 99 would be helpful for both Sequoia and Yosemite. The map looks good for 395--dots possibly in Lancaster, and Lone Pine or Bishop.

I just got a report from San Joaquin Valley Air Quality Management District (see the copy at the bottom of this page There is financial support for putting in infrastructure, but unfortunately there is an assumption that it is all Leaf/Volt infrastructure. So lots of talk about convenience charging while at the supermarket, not so much concern about somebody staying overnight and charging (and no focus at all on bringing a supercharger here, although they do discuss high voltage charging technology). The problem, of course, is that this means that people visiting Yosemite and driving through Fresno are going to take a gas vehicle if they have one and leave their Tesla at home.

It is around 90 miles in the summer through the high elevations Fresno to Yosemite, and 110 miles in the winter going through the lower elevations (i.e. through Mariposa). If it is a day trip from anything south of Fresno (i.e. Visalia), there is no way it can be done with a Tesla unless there is a charger involved no further from Yosemite than Fresno. A supercharger in Mariposa would do the trick, but a regular charger isn't going to be fast enough to make a Tesla day trip to Yosemite work. And trust me, I know a lot of photographers who do lots of day trips, leave home at 3 am, get to Yosemite for sunrise, drive around the valley floor to follow the light, and drive home. The Tesla range is just slightly too short to support this without a charge mid-way.

Adding to my confusion about why there isn't infrastructure already in place is the fact that 3 of the 5 most polluted metropolitan areas (air pollution) in the United States are in the Central Valley. Yosemite Valley itself has a pollution problem at times. 60% of the volatile organic pollutants come from auto exhaust. This isn't a hard sell on the public policy/public health side.

Anyhow, all that said, I'm in Fresno and I have a 40 amp NEMA 14-50 outlet for charging my model S right at the street end of the inside of my garage (as well as a GE Watt Station for my other car, but that is installed on the house-side of the garage and the cable won't reach to the driveway). It works with the mobile charging cable adapter that comes with the Tesla and charges around 29 miles per hour of charge. With some advance notice and preferably at off-peak rates, I might be able to help fellow model S owners on their way to Yosemite.

In the meantime, though, I keep looking at the supercharger map and I'm having a lot of trouble figuring out why there (apparently, the dots are tiny) isn't a planned supercharger in Oakhurst, Midpines, Mariposa or Fresno.

Oh, there are also 2 J1772 chargers at the San Joaquin Air Quality Management District office in Fresno, but the times I've gone by there, both spots were filled with gas/plug-in electric hybrids that had already completed charging (and had no contact information to call the owner and ask them to move). So yes, you could try charging there, but my guess is that the spots are used as regular parking spots by employees with chevy volts and you'd need to arrive before they did to snag a spot.

I am working with the County government and a land owner to get a Supercharger in Mariposa. Keep your fingers crossed.

Do you have authority to promise one, or are you doing it on spec?

All I can and am doing is get permission from relevant land owner and making sure the County BOS, Building and Planning Departments will support an application and then apply to Tesla for a Supercharger in our area. No authority or promises, just an serious attempt to make it happen.

Thank you shs. Much appreciated.

I would love a supercharger in Yosemite. One big sad point in ordering a Model S is knowing that I can't realistically take it out there.

The Ahwahnee Hotel in Yosemite valley would be a good spot for chargers, wouldn't need supercharging 30amps would get you filled up overnight. It's a great place to stay and the food is excellent.

@Gizmotoy - yes you can. Rent a cabin with dryer outlet..

@Kleist "What makes me wonder that 395 has SC in the final plan, but not 99 - 99 is a highly traveled road"

People in Santa Barbara and LA go skiing/biking/hiking at Mammoth Lakes, using the 395 to get there.

It's like Bay Area people using the Folsom supercharger to reach South Lake Tahoe for their skiing/biking/hiking mountain vacation.

It's part of the lifestyle that needs to be accommodated to drive sales in this region -- the 395 is important.
