Tesla has to make all models charge as fast as possible

Tesla has to make all models charge as fast as possible

Tesla lowering charge rates on vehicles they don’t want to sell is foolish. We get it, they only want to sell performance long range where they make a good profit. And oddly, they get it, they know their cars are too expensive for the average person. They also know EV wont take off until charging becomes very fast. So what genius thinks it’s a great idea to slow the charge rate on the cheaper cars??? No, make it as fast as possible!!!! Get rid of all easy hurdles on people to go EV, that should be top priority!!!

What are you talking about?

Magic 8 Ball | February 11, 2019

You should get right on that priority Hal since it is so "easy" an' all.

spuzzz123 | February 11, 2019

What is this? Tesla unnecessarily slowing charge rates to deter demand? Are you sure there aren't other, technical reasons why charge rates are slower (for example, smaller batteries cannot charge as quickly, or would risk damage if charged quickly?). Do you have a source for this?

I am with you that it is completely illogical to reduce charging bandwidth anywhere. The last thing they want is more headlines talking about lines at superchargers. If they don't want to sell the cars, make them slower. Or how bout this -- just don't offer them.

My 3 charges much faster than my S. What is this post about?

Hal Fisher | February 11, 2019

The mid size battery 3 is stuck at only 32amp. The S can go over 100amp. That seems like a marketing thing.

I don’t think there’s an option for me to be ‘on it’ at tesla. I have my own battles where I work. I’m on shit there.

jordanrichard | February 11, 2019

If anything, the cars are charging faster. I have noticed that my 2014 MS is charging faster at some locations that I am very familiar with. So in counter to your logic, why would they want to make my "old car" charge just as fast as new MS's....?

Magic 8 Ball | February 11, 2019

It never ceases to amaze me how many folks know how to do EV's better than TESLA, yet have no clue as to how/why decisions are made internal to TESLA.

gmr6415 | February 11, 2019

@Bighorn, I believed the OP is referring to the fact that the M3 midrange won't charge as fast as the LR at home.

Hal Fisher | February 11, 2019

Bighorn, what year and what size battery does your S have? Pretty sure the mid 3 has the slowest charge rate of all (unless maybe the old models).

Hal Fisher | February 11, 2019

There are always the dummies resistant to change, even here! Haha!!!

Kathy Applebaum | February 11, 2019

I really doubt that it's marketing.

First of all, I'm not sure how you get "The S can go over 100amp". Tesla says 48. (https://www.tesla.com/support/home-charging-installation/onboard-charger)

I like to think of charging like a book shelf. When the book shelf is empty, it's easy to find a place to stick books as you pick them up. You can even have a couple of people putting in books and they don't trip over each other. As the book shelf fills up, it's harder and harder to find an empty spot so the books get put away slower and slower.

The mid range (and soon the short range) start with a much smaller book shelf. It's harder to find empty places from the get go, so charging, er, putting away books is slower from the start.

Another reason Tesla limits the charging speed is heat. Charging heats the battery. Larger batteries spread that heat over a larger area, so you can charge faster without issues. A smaller battery needs to limit the speed to avoid excessive heat. If you think 32A is bad, my Leaf was limited to 24A. Nothing to do with marketing -- strictly heat management on the tiny battery.

Magic 8 Ball | February 11, 2019

When I charge smaller batteries at home the charge rate is a usually a factor of the total amp hours of the pack. Smaller packs get lower charge rates in my experience.

kevin_rf | February 11, 2019

Maybe the SRB has fewer cells, so can take less current all at once.

Don't know, just did a 400 mile trip to DC and back, every stop the car was ready before I was ready for the next leg. Just need to work on a faster way to empty the bladder and pick up and eat junk food at each rest stop.

Bighorn | February 11, 2019

Oh, this isn’t about supercharging, but level 2 charging.
Without a $2000 upgrade, the my Model S version charged at 40 A. I paid for 80 A charging and probably took advantage 3 times in 226k miles. Model 3 charges at 48 A. No S charges over 100A—I think the latest max was 72. This has evolved over time in large part to protect the car and home circuitry. There’s no pay to play going on here.

gmr6415 | February 11, 2019

@kevin_rf, After our first long trip and a lot of stopping at malls and such to charge my wife decided that driving the M3 on long trips was going to result in one or more of the following:

1) Make her gain weight
2) Spend too much on shopping (which she actually hates to do)
3) Turn into an alcoholic

82bert | February 11, 2019

Hal is a notorious weirdo on these forums. He loves to stoke the flames. This post is just more nonsense from him. He is trying to create an issue out of nothing.

jordanrichard | February 11, 2019

He likes to stroke his what!!.....? Ohhhh, you said stoke. Nevermind............... :-)

Bighorn | February 11, 2019

@82bert
I’m gathering

httran26 | February 11, 2019

This is a misinformed topic. The Model 3 Long Range has an onboard charger that can go up to 48 amps. The mid range version has an onboard charger that can go up to 32 amps. This is one of the changes that allows the mid range to be sold at a lower cost. This information is not related to supercharging. For supercharging, you still get the fast charging speed.

andy.connor.e | February 11, 2019

At no point in time has a Tesla vehicle ever been able to charge over 100A on NON-SUPERCHARGER. OP has no idea what they are talking about.

lbowroom | February 11, 2019

Hal has no idea how anything works. Just ask him about security systems and visors.

Mozart | February 11, 2019

Is OP a liberal?

kevin_rf | February 11, 2019

@gmr6415 For everyone's safety, I would recommend your wife not mix long trips and #3. For long trips, I have learned the trick of only take as much charge as you need for the next leg. On the DC trip, I only made two stops and both times the car had more charge than I needed for the next leg.

SteveWin1 | February 11, 2019

What a retarded complaint. Go buy some rechargable AA batteries and a Kill O Watt to measure power usage. Charge 1 battery and measure how much current your charger is drawing. Now charge two batteries and read the current draw. Based on your post, your response would be, "What!?!?! It pulls more amps when charging two batteries instead of one? Is this a conspiracy by the battery companies to make us buy more of their batteries?"

A battery pack with more of Tesla's little cells is clearly going to be able to take more amps because it is divided among more cells. Model S and X have much larger batteries. If you look at range added per hour, the Model 3 actually beats the socks off of the Model S and Model X for any given home charging solution. So...maybe not a conspiracy?

andy.connor.e | February 11, 2019

@SteveWin1

That being said, it doesnt even matter. Because No Tesla at any point in time has ever been able to charge over 100A that is not a supercharger.

Bighorn | February 11, 2019

No Tesla has charged over 80A on a Level 2 to my knowledge.

lbowroom | February 11, 2019

Like I said, Hal is a wiz with all things technical.

Hal Fisher | February 11, 2019

Actually, I am. You probably can’t do what I do for a living (java, js currently). And lowblow blows low. Ask him about how much gum you get out of a gumball machine for a quarter. That’s his highest technical ability.

Hal Fisher | February 11, 2019

I see what the problem is. They go by amp on the interface and watts on the charger. What’s next, volts on the brochure? Genius!

andy.connor.e | February 11, 2019

ur a moron Hal. Hopefully this gets flagged.

lbowroom | February 11, 2019

So in Hal's world, all it takes is writing a line of code for the world to fall in line...

posinator | February 11, 2019

This thread doesn't make sense with how I charge my 3. I spend 1-2 seconds plugging it in at night and it's charged by morning. Seems like a fairly common use case. What could be faster than that? I think I have supercharged on 6 or 7 days in the last nine months. Always seemed pretty convenient, charging speed was never an issue.

Tuning In | February 11, 2019

There's stupid. And there is: so stupid that someone doesn't even know that they're stupid.

andy.connor.e | February 11, 2019

The probability that this person is intentionally writing like this and does not care about whether what they're writing actually makes sense, is about 90%.

Anyone with even half a brain cant make any sense from the original post.

SteveWin1 | February 11, 2019

@Tuning In, you literally made me laugh out loud.

spuzzz123 | February 11, 2019

Holy crap I take it you guys are jumping his case for something other than this particular post. Wow. Y'all are as mean as a bunch of junior high kids at the popular kids lunch table!

rxlawdude | February 11, 2019

I just added another name to my twit filter.

Even when clearly shown he is wrong, he continues. I won't open the pod bay doors for you, Hal.

howard | February 11, 2019

DC fast charge was a fairly expensive upgrade on the Bolt and I never used it. Cheaper the car the slower the charging. Economic decisions. If you wanted faster charging should have bought the LR or Super Charge. It is all up to you. Has nothing to do with Tesla.

lbowroom | February 11, 2019

spuzz, it's a long list of stupid, along with insistence that Tesla needs to rectify the imagined problem immediately. To see him present that he's a Java programmer to validate his tech savvy... well WOW! Why didn't he just say so? That somehow vindicates all his preceding lip flap.

jjgunn | February 11, 2019

It's so easy to start a car company. Especially in 'Murica. Where you have real adults with real lives & real families building the vehicles. Piece of cake!!

Unlike China who has child labor. It's tough over there.

Some Tesla's have 72 Amp chargers. (Mine does) It seems Tesla has lowered that number to 48 Amps Max moving forward. If the medium range vehicle has 32 Amps Max it's to protect the vehicle / battery pack.

Kathy Applebaum | February 11, 2019

@Hal "Actually, I am. You probably can’t do what I do for a living (java, js currently)."

I not only do it by day, I teach DBMS and data mining at the university at night. But I'm smart enough to know that doesn't make me an expert on things outside of my field.

Rt002k | February 11, 2019

Bigger battery = more cells
More cells = more distribution of current
More distribution of current = higher total current capability

The short-range model 3 has 2/3 the capacity of the long range. 32A is also 2/3 of 48A. A lower rated onboard charger was designed for that use-case. Looks like they put the smaller onboard charger on the mid-range as well to save cost (which is passed on to the customer).

But - you also save yourself $500 because 32A is the max rating for the 2nd generation UMC - there is nothing to be gained by purchasing a wall connector. So, yay $500 savings?

Rt002k | February 11, 2019

Also - I have an engineering bachelor's and business master's degree. Doesn't mean I know jack about anything outside my field - like for example Java, or building a car. Amount of education does not equal technical proficiency in unrelated areas!

gmr6415 | February 11, 2019

@kevin_rf, I should have stated my wife doesn't drive the M3 on long trips. In fact the only time she's driven it was after I had surgery and she had to drive me home. No drinking or supercharging on that trip. All said, she was joking and really doesn't drink much at all.

TM3Q | February 11, 2019

First I must say the original post doesn't make any sense!

There's a difference between someone asking a question or starting a conversation about something he's seeking answers and someone bashing Tesla for something that's not even making any sense!

I love electronics and made it a carreer. Today I see a non sense post using false electronic topic to bash Tesla well Bravo! What can I say....someone needs attention.

Why not just ask a question about why there's a different charging rate between model per example and some would be happy to answer you.

Funny that I see a post about charging rate and I have being playing for fun with lithium and NiMH battery in my lab lately.....If I want to recharge my battery super fast I can (just have to change a resistor value in my circuit) but I can't guaranty it will last that long that's if it doesn't explode first haha

Cheers
