Charging past 80% is a waste of time. The fuller the battery the slower it charges. It’s much faster to stop twice to charge half of the battery than to stop once to charge 100%.
When I'm charging the day before to start with 100%, it makes a lot of sense.

From a leadership point of view all it takes is someone at the top saying this will be done. Making Supercharger monitoring and maintenance a priority. As opposed to MBAs seeing it as a cost center to cut against.
Only one data point, but when I did a long road trip, I encountered a tech at an Electrify America station. He told me they tend to only make servicing a station a top priority when none of the stalls are working. Otherwise, broken stalls are put into a queue for service.

They are a natural monopoly; nothing wrong with dominating and providing the best value, but we note when monopolies occur because bureaucracies tend to naturally exploit them.
Monopoly by what metric? What’s the difference between being a market leader and a monopoly? Investopedia defines a natural monopoly like this: “A natural monopoly is a type of monopoly in an industry or sector with high barriers to entry and start-up costs that prevent any rivals from competing.” But there are many rivals to Tesla in this space. ChargePoint, ElectrifyAmerica, and even a start-up called Volta that do…

Tesla locked in most teslas into their own network for one. Its theoretically possible to use another one but it would be difficult and cumbersome
If there only was a system that could automatically disconnect a charged Tesla's and move the to another spot. You know something like a autopilot in a plane.../s The fact that the charges still can't automatically connect and disconnect like it was demod with this snake thing so many years ago and that the Vegas loop still has drivers leaves me with very little believe that Tesla will ever have an actual working and…
Or just use wireless charging, then there are no cables.
Wireless charging for EVs can be efficient: https://www.youtube.com/watch?v=AE1gaNO9nj0
And wired charging is not as efficient as you might think: https://www.youtube.com/watch?v=iLmIIe9N_aI

Could not agree more. This seems pretty reasonable, but I scoffed reading this part of the article: > Eventually this problem will mostly go away as they add more chargers. Maybe the problem will go away but the fees will likely remain and be joined by others. Electric vehicle fueling seems like one area to be absolutely principled about avoiding vendor lock-in.
Tesla has a monopoly on working electric car charging infrastructure. There are other chargers out there but all the others work poorly
No. The best chargers are manufactured by Alpitronic and Kempower.
If you want to see EV infrastructure done right you need to look at Europe. North America's EV infrastructure is a basket case in comparison.

At least in the seattle area it doesn’t feel like the supercharger density is keeping up with sales of cars. AFAIK there have only been super chargers built around the periphery of the region in the last few years and many existing chargers are older lower power chargers. The east side (Bellevue, Redmond, etc), which has a HUGE EV following, with Teslas everywhere, has precisely zero super chargers. We happen to live…
> supercharger density is keeping up with sales of cars I thought most Tesla owners were rich enough to have charging at home?
I would also note you can get used teslas, even higher end ones like model s, for $20k or less, which isn’t unaffordable. Because the batteries can last decades and the mechanics are so simple they effectively last forever it’s a pretty good care 10 or 15 years later.
Fantastic news. This will help reduce the few people who cluelessly occupy plugs for longer than needed at hardly any benefit to themselves and at some cost (time cost) to others. And make people who foolishly bought low range cars “to save money” help pay for any impact their choice has on others.
>And make people who foolishly bought low range cars That has absolutely nothing to do with this subject.
