Million Watt EV chargers.

"'Megawatt' EV Chargers Have Landed In The U.S., But There’s A Problem"​

EV charging power availability is getting ahead of the new EVs. Not a problem--not even for my largest electric motorcycles that can only charge at 20KW.

The max my Tesla can accept from any charger is 250KW. My Chevy Bolt, only 55KW. But I do not do long road trips via car, so all this means nothing to me, but it could to some others.

IMO, the EV charger companies are simply just getting ready for what they know is coming in a few years with more and more people travelling far in EVs.

Interesting... Megawatt let's see about the biggest house (Reasonable house not a 100 room McMansion type house) 250 amps at 220 volts 55,000 (55KW)

One of the limits is the battery cooling system. Most LiFePO4's get a bit..er.. hot at very high rate charging.. China as develpoed one that can take much higher charge rates (Blade battery)

Not as high a power density as what is in common use but up-sized to a Semi... Yup it could suck a megawatt.

A hypocrite says one thing, but does another. You've been arguing for years why long trips in an EV is not a problem.

That's ok Don. Yes, we understand you prefer riding a motorcycle or driving a gas guzzling motorhome. Just quit preaching how great an EV is for a long trip.

Ask those many who do it.

I do not do long trips in any car, but if I were going to, it would be my Tesla for sure.

But some people are in bigger rushes than others, even in ICE vehicles. What is a "problem" to one driver , could be a nice appreciated break to another.

Sometimes it is nice to have choices. When plugged into any EV charger, many EVs (most?) can adjust the charge rate to match what you wanna do in the area but can only charge up to the highest possible for the EV. If that highest possible KW charge rate can even be higher, it gives more choices, less time possible.

Not everybody is in a big rush, but such choices are a good thing.

Those Laundromats that took out all the dryers and put up clothes lines are doing really well with folks not in a hurry.

Based on the discussion of this thread, I'm still not a good candidate for an EV anything. Why? Well, when I retired I thought I could take life easy, relax, go slower, take my time, enjoy and smell the roses. And when traveling, you know, it's kind of nice to stop a while and refresh during "fuel" stops. EV's afford that slower pace, I agree.

Little did I know that when I retired my pace of life skyrocketed. Now, I don't have "time" for anything. It's always rush, rush, rush, do this, do that, get here FAST, get there FAST. Travel across the country... really need to be there "yesterday."

Nope, EV's still will not work for me, even in retirement. I simply don't have the "time" to wait for a "recharge!"

The older you get, the less time you have!

After all, "Life IS like a roll of toilet paper ... the closer to the end, the faster it rolls!"

Now, I don't have "time" for anything.

Does that include time for going out of your way to go to gas stations for local trips as most car trips are used for (and by far!)? Charging at home, even while typing these message or while sleeping means you never need to go to a gas station or a charge station on the road. I almost always leave home with near a full "tank", but I do not charge up every day--far from it.

A 12kw home charge like I get means I get more than 40 miles added for every hour of home charge--that is more than most people drive per day in the USA.

As I have said before, if the modern EV came first and then the ICVs, people then would be complaining about the need to go to gas stations for local trips.

Also save time with no checking and changing oil, filters, etc. And in many areas, smog checks.

Had some friends come visit for a couple days. They knew nothing about a Tesla or other than what they had heard electric cars are bad. I drove them in my Tesla for one stop, then got him behind the wheel. He at first was afraid of the "feel" and power, but about 20 minutes of driving he was really enjoying it. The next day he said can I drive it again?? Sure, by the time they were about ready to leave he was searching on line for used ones close to where they live, another state. He thanked me for allowing them to experiance the Tesla and how it let them feel for themself what it was all about. Changed their perception. He could not get over the power and smoothness and that I plugged in at night and had a full tank by morning. Love getting new folks into the seat.

Same happened to me in my Reno motorcycle club. One ride in my Tesla and he goes out to buy a new Tesla Model Y (but mine is a M3) the next day and just loves it.

In the Tesla, it could be best to turn the regen down before others try it, or at least explain the big difference when one lets go of the accelerator pedal. Also, turn the regen down when you have rear seat passengers, it can make them not feel well--but only seems to happen when they are in rear seats.

From a Brave Browser search:

"People feel sick in the back seats of Teslas primarily due to a sensory mismatch where the brain receives conflicting signals from the eyes, inner ear, and body, a phenomenon exacerbated by the vehicle's unique driving dynamics. Strong regenerative braking creates sudden, unpredictable deceleration that feels like being "pulled into quicksand," while instant torque delivery causes abrupt acceleration that passengers cannot anticipate.

The silent operation of electric vehicles removes auditory cues like engine revs that traditionally help the brain predict motion, making the lack of vibration and sound disorienting. Additionally, rear-seat passengers are more susceptible because they cannot see the road or control the vehicle, meaning their inner ears detect motion that their eyes do not confirm."

FWIW, I do not like the way Tesla does its default for decelerating regen, it's quite high at the default and adds nothing with the brake pedal--unlike all my other EVs (8 EVs total--six are motorcycles). My Zero electric motorcycles have 200 settings for regen (100 for deceleration and another 100 for the brake pedal) and can be turned off. It's set by a Smartphone with a scale from 1 to 100 for each.

IMAO, we should be able to turn regen totally off, especially for when we have back seat passengers--then make it feel like an ICE car. Also use the "chill" mode, but it still accelerates much faster than any ICE car I ever owned.

But when you have rear seat passengers, "chill" and the lower regen setting will help a lot.
