Tesla has set up a large number of fast charging stations across the USA. Called the Supercharger network, these stations have the ability to charge you electric car up to 80% of the battery capacity in 20 minutes.

While this has made it convenient for many people to undertake journeys, the number of Tesla owners outnumbers the number of Supercharger stations. If many Tesla cars need to be charged at the same time at the same station, it would lead to serpentine queues (like the ones we have at CNG filling stations in India) - particularly in areas where there are high number of Tesla owners. Unfortunately, this is exactly what is happening.

Here's a scene from a Supercharger station at the San Luis Obispo, California:

A Tesla Model 3 owner who stopped at the Supercharger station on Saturday night revealed that at approximately 6:30 pm local time, it had been more than an hour since she had been waiting in line. There were dozens of cars ahead of her:


After a long wait, she was able to plug in. However, the Supercharger itself was charging at slow speeds. It showed a recharge rate of 56 miles of range per hour of charging, which is way slower than a typical Supercharger speed of 300 miles of range per hour of charging:


About 20 minutes after she started charging her car, one of Tesla’s mobile Supercharging units arrived to solve the problem:


However, 40 minutes after the update, the Supercharger stopped working and left her car with a 43 percent charge. The car next to her's got the same error message. A staff member of Tesla got the Supercharger to work again, but the car was still reporting that it needed two more hours to charge:


Tesla is the only electric car manufacturer that has built thousands of Supercharger stations. Other manufacturers are not even close. However, as we have seen here, these are not going to be enough to cater to the millions of car that Tesla plans to build.

this is due to the rush of thanksgiving weekend travel, it doesn't happen all the time.

What about Electrify America owned by VW / Ford and co.? Just to get things in perspective, how many of those are operational against the Supercharger network? If only Tesla makes their chargers compatible with Electrify America, this would reduce the traffic load on Teslas network benefiting everyone!

Until electric cars can be "topped up" as quickly as petrol / diesel cars, the best ways to charge them IMHO are:

- Overnight at your residential parking spot

- At your office

True. In a country like India though, such lines will be commonplace at all public charging outlets.

I believe Tesla's network is still far wider (although Electrify America is catching up fast).

I read that Tesla came out with their own unique charger because, when they launched the Model S, the then-standard wouldn't support supercharging. So, in a sense, they had no option. Whatever the case, all EVs will have to move to a common charging port soon.

Also, Tesla has adapters that allow its cars to be charged @ Electrify America outlets.

The technology is fast evolving, we have 150kw chargers already, who is to say we won't break this barrier in 2020 and go even further. Everything in EV, is breaking ground, the price per kwh has plummeted in the decade and will further go down as battery improvements are made.
To increase the infrastructure, which is easier, establishing a fuel pump or a charging station?

Indeed, the west coast being inundated with Teslas has caused this kind of situation to unfold a few times recently. I recently drove from Michigan to South Carolina and back on Thanksgiving weekend, and on my return journey, I pulled into a Supercharger station in Wytheville, Virginia. Call it a coincidence or just bad timing, but within the next half hour, one by one, 8 more Teslas pulled in. I was lucky that there were 3 empty stalls when I got there (only two other cars), otherwise it would'be been up to a half-hour long wait. My charging was done in 35 minutes, so I left.



That said, I don't expect this to be an issue in the near- or long-term. In the near term, as long as electric cars are in the minority, the number of such incidences will be negligible (nobody is creating a thread about the other 999,999 times that supercharger station has been empty - it only got public attention because of the shock value). Considering the number of road trips majority of the public take each year (gotta be less than 10), with the rest 355 days of the year being spent ideally charging at home or at work, the current Supercharger network OUTSIDE OF CALIFORNIA seems adequate for the number of cars on the road. Of course, Tesla should take some steps to address the shortage in their home state, especially in view of the impending flood of Model Y's that are going to hit the streets next year. The mobile Superchargers brought in by Tesla as an emergency measure was a good initiative, and you can bet they'll be prepared for this sort of thing next year during holiday time.

In the longer term, as soon as electric cars reach critical mass, third-party DC fast charging charging networks will spring up as independent businesses and manage it efficiently - its just a market demand vs supply equation at that point. Then one will have a choice of Tesla supercharger vs other CCS/Chademo fast chargers, although most likely Tesla Superchargers will be cheaper (current DC fast charging stations being rolled out by Electrify America in the US seem to have almost double or more the cost per kWh than what Tesla Superchargers cost).

In any case, for the US market at least (where most everyone has access to home or work charging), 95% charging needs of people will be taken care of outside of such DC fast charging networks. The slight inconvenience caused by having to wait is IMHO worth the advantages of EVs in general.

Spot on.

Yeah there need to be other players in the standardized DC fast charger infrastructure space. (Well, firstly the EV industry should make up their mind about the charging plug types - there's still two competing standards in the US). Tesla alone cannot fulfill the demand they are going to create with the Model 3 and Model Y, not without significantly more capital expenditure which I think is going to be hard for at least another year for them.

That's right, but there's still some work to be done for being able to charge at Electrify America stalls.

Annoyingly, while they do have a European CCS adapter for sale for the European CCS charging port, and a Chademo adapter for the US (which is insanely expensive @ $450 a piece), Tesla hasn't yet launched a US CCS adapter which can be used at EA charging stations in the US. This is particularly annoying because increasingly, CCS is shaping up to be the faster charging standard with up to 350 kW speeds, whereas the fastest Chademo stall I ahve seen is only 50 kW. Here's a screenshot of the different AC and DC fast charging plug types (you'll notice that the DC plugs in US and EU are just the AC overnight charging plugs with two additional pins).




Speaking of third party DC Fast charging infrastructure, here's the Electrify America charger that has come up at my nearest Walmart parking lot (EA has partnered with Walmart for the US). It has 4 stalls, with 1 of them being a 350 kW CCS stall, two of them being 150 kW CCS, and the last one having both a 150 kW CCS and a 50 kW Chademo (I believe you can either use the 150 kW CCS or the 50 kW Chademo - but not both at the same time. Same with the other stalls - although they have two plugs on each stall, only one can be used at a time, I read somewhere that this was done to support cars having charging ports on both sides). Also notice the data plate attached to the stall - up to 920 volts, 500 A - that's 460 kW designed capacity! (of course rated capacity needs to be lower but that's a good amount of future proofing I'd say).

Can't wait to be able to use these fast chargers, seeing as all my nearby Tesla Superchargers are the older V2 Superchargers having 150 kW capacity. (Newer V3 Superchargers are 250 kW, and the Model 3 can take in up to 250 kW). C'mon Tesla, out with the CCS adapter already!

Tesla recently opened the world’s new largest Supercharger station with 56 charging points. The charging network is located between the Bay Area and Los Angeles – two of Tesla's biggest markets in the world, as per Electrek. Supercharger networks enable fast-charging for long-distance travel.

The supercharging station location also has a convenience store and a restaurant that Tesla owners can use while their cars are getting charged. The EV maker has also built solar canopies providing shade to the charging vehicles while also helping power the Supercharger station.

Tesla has now installed more than 6000 superchargers across Europe, including more than 600 locations in the UK and Ireland.

It has taken Tesla just eight years to create 6039 chargers, following the installation of the first European Tesla supercharger, accompanying the arrival of the Model S, in Norway in 2013.

After all this, the problems that are known in the first world, Our folks in India are still installing 50kW chargers and calling it work done, which is only going to create thrice the amount of queing just if the number of cars and chargers are the same, but will be a disaster given the population of our country.

When are we gonna learn from others mistakes...

Yes, this is going to be a huge problem in the future, but, this is an issue that the government needs to address very quickly.
One of the main reasons why this is going to be difficult is the electricity rules and regulations. We need an HT license if the power load is going to be more than 70 HP in any industry. With this comes huge number of issues, in our company we are currently in the process of expansion and going from our existing load of 200KVA to 700KVA. This has been going on for about 6 months and it is still not approved, our machines are all in place and we are unable to switch them on.
This is for a company that has had HT for 3 decades and its just applying for an enhancement of load. Just imagine the issues a new company would face with a new application. There are a massive number of rules to be followed with respect to the transformer installation space required and the protection devices to be installed. Minimum amount of space required for installation. Availability of power in the HT line going through the location. You better hope that there is an HT line else, you will pay through your nose for laying the HT line.
A huge amount of money is required to be paid as a security deposit for the contracted maximum demand (3 months from memory). Plus you have to pay for the usage of 75% of the max contracted load even if you do not use it.
So, all in all, the govt likes to talk but has not shown that it can walk the talk when it comes to simplifying the process of getting electrical power.
I very much doubt that we will have many high capacity DC chargers across the country. Hopefully they will install them in the highway gas stations who most likely will not have any shortage of space which would not be available in the city locations.
Anyways, I will get off my soap box now

To sum up your entire post, LICENSE RAJ, a cancerous concept left by Britishers has been plaguing India since independence & will continue to do that because even with all "VIKAS" talks, the ground level is altogether different.

Yes I know what you are talking about. Because one of our clients when they had to upgrade their connection, they had to pay north of 8L for a 75hp connection updrading from a 50hp and got it done after running around for a couple of months and greasing the required palms.

This is the main deterrant for setting up the chargers at this point of time. I had decribed this problem long time ago here. https://www.team-bhp.com/forum/elect...ml#post4882819 (Govt mulls installing EV charging kiosks at around 69,000 petrol pumps in India)

For Sure.the worst thing is that the electricity board people think that they are doing you a favor by giving you a connection and that we should be grateful to them. Idiots 🙄

Oh god , the electricity folks! I would rate the electricity board here, TNEB most corrupt to deal with. Far more corrupt than even the cops or revenue officials or any government department.

We applied for a 2 way meter for our solar panel . Hasn't been fixed for 5 years There is also a danger that extremely high loads will trip our fragile grid and break it down. Guess our country should be content charging from a normal 220V port.

Yeah, its a universal story from all over India, the only exception that I know of is Gujrat. I have heard that the govt is trying to do something about it, but, there is no way that the EB people are going to let go of a major cash cow like this.
If this remains, then we can all forget about high power fast charging network across the country.
