Interesting - they've changed this a couple of times now.

The electrify america chargers are supposed to be able to pump that out and that taycan was supposed to take that but can only absorb 270 for a few minutes last I saw.

It will be interesting to see when (what soc) the unit will take that rate and for how long before it tapers off.

The devil is in these details.

I for one hope they nail it and give tesla some competition.

That’s where my concerns lie with EV’s.

There’s no way you can super-fast charge at home, 200amp service can only do so much, especially considering not all of it can be allocated to the car.

The best most folks can do is Level 2, and that’s not going to charge a depleted 200+ mile battery overnight.

For sure - if you are looking for 200 miles a night you may want to upgrade your panel.
Most guys have nowhere near a 200 mile commute and 1-12 horus on a level 2 keeps them ahead of the game.

Apparently you haven't seen Calif Gov Newsom say that CA will not allow new oil fueled vehicle sales after 2035. https://www.nbcnews.com/science/env...ning-sale-gasoline-powered-cars-2035-n1240878

Anyone think we'll suddenly have as many EV charging stations as gas stations in 15 years? I sure don't. Also, his logic for doing this really has nothing to do with the issue he stated it was supposed to solve. It's like saying requiring everyone to run around naked will solve global warming.

with a little luck newsome will get hit by an electric car

 

[rrrr]

I think its cool. Just wait for wireless charging for the cars. That's when Electric is going to go mainstream. Your car charges while your shopping, waiting at a stop light etc.

You're dreaming if you think inductive charging will ever be used in this lifetime to transfer 100-200 kW in a few hours. It isn't anything like charging a 3600 mAh cell phone battery.

The secondary magnetic inductors in the vehicle would have to weigh hundreds of pounds, and the primary inductors would have to be cast into your garage floor and fed with 480 V three phase power at a minimum. It sure as hell isn't going to happen at the mall or a stoplight.

What? You see a problem with a neighborhood of 1,500 sq ft houses running 400 amp services lol?

I hope people keep buying these because it just causes the tech to keep improving.

You new here ? If you don't have a 400 A service on your tract home, with natural gas appliances, back of the bus you go mister.
Your buddy might be braggin he's got a blown BBC in his vintage Chevelle, but will bend a knee when you counter by announcing you've got a 400 Amp service.

The Electricity it takes to charge the new Tesla's and this new Bummer is the same amount used for powering 3 family of 4 houses (per day) per charge! -- With all that wind, solar, rolling blackouts and soon NO fuel? ............ lmfao

 

[TPC]

Not unusual for people to knock on our RV door asking for gas or a tow. I won't be surprised if one of these rigs rolls up asking for a charge.

Sorta related...I’ve heard/read people say “I’ll just keep a little 2000 watt generator in the trunk in case of emergency”...not realizing that Level 1 charging might net you 4 miles range per hour of charging LMAO

Plus since they are probably playing on the internet in the car while charging it would be net sum 1/3 of that....

 

[Uncle Dave]

interestingly the batteies total capacity of 200KWH is equivilant to 5.93 gallons of gasoline.

So if it gets 350 miles using 100% of thjat battery its getting 59E MPG, MPGe as Ive seen it written

Probably the worst efficiency of a battery vehicle to date, but significantly more efficient that running it on gasoline.

This is super interesting re EV’s! Where does this number come from?

 

[Sleek-Jet]

Keep in mind that watts is watts. The amount of power doesn't change.

So a comparable gas powered vehicle still uses the same amount of power, it just gets that power from hydrocarbons instead of electrons.

 

[Uncle Dave]

It can be extrapolated many ways - if a household uses 50 KWH per day, one can say it takes 4 days worth of electricity to fill the car with a 200 KWH battery.

 

[pronstar]

Keep in mind that watts is watts. The amount of power doesn't change.

So a comparable gas powered vehicle still uses the same amount of power, it just gets that power from hydrocarbons instead of electrons.

But in an ICE only ~25-35% of gasoline energy is propelling the vehicle. The remainder is wasted as heat/exhaust/friction.

So 5-gallon equivalent energy in an EV is more like ~15 gallons of gas in an ICE.

at a steady 70 MPH a model 3 long range will go about 290 miles on an 80 KWH pack or about 2.37 equivalent gallons of energy - or get the equivalent of 122 MPGe.

Any idea on what one Mega Watt cost to produce? Assuming the same method of generation the cost should be relatively the same across the US?

Sort of....

GM is taking "reservations " They cannot sell direct to end users.

The dealers will offer them to reservation holders (after their friends and family jump the line) when they get them.

It will be interesting to see what "market adjustments" get put on the sticker, and what they will really go for.

Between $20 and $50 depending on area of the country and such. Figure mid-$30 as a good average.

That's wholesale price.

Agreed and that makes the ICE look even worse.

The statment that an electric vehicle uses the same amount of electricity as a house is a bit of a red herring. A conventional vehicle uses the a similar amount of energy, or more as the case may be, but that is just not how people think about the subject.

Is there a price premium if you get that megawatt super fast, compared to slowly drawing it over say 6 hours?

I seem to recall some saying there would be, but I don’t know for sure...

Correct - a single large vehicle can consume as much actual energy as a half a block of houses.

That energy simply come in the form of a liquid that is extracted from the ground, highly refined, then delivered in large containers, to be put into even larger containers, to then be pumped into smaller containers to ultimately be transformed by combustion converting it to forward motion (at a fairly low efficiency rate)

Well, it is complicated, but yes the faster charging rate will cost more but not because of the energy.

What you're asking for is a difference between capacity and energy. It takes a lot more infrastructure (capacity) to supply a large amount of electricity (energy) in a small amount of time than it does to spread it over a longer time period.

For example, you need 100kW to charge a battery, but you want it in one hour. The utility would have to build a 100kW utility system to charge that battery. But if you could charge the battery over 10 hours, the utility would only need to construct a 10kW system.

The utility covers these costs by charging a demand on larger users. The demand charges cover the infrastructure costs in properly designed rates.

That’s one reason why EV’s make sense - less conversion. You go straight from solar panel to electricity, for example.

Compared to hydrogen, which starts with water or natural gas (which is already a fuel), add energy, get hydrogen, convert hydrogen into electricity.

Every time there’s a conversion, there’s loss. Can’t get around the laws of thermodynamics.

This is also correct and one reason why high speed chargers often price by delivery tier as well as KWH.

This is also why use the 3rd party Electrify America network of charger in cali at high speed is often MORE than an equivalent tank of gas.

@rrrr Just a question. How much efficiency loss you think would occur with induction charging if its ever developed for high amperage fast charge applications?

 

[rrrr]

Wellll...inductive coupling depends on distance between the primary (charger) and secondary (vehicle) devices, and I would suspect with the energy transfer rate we're discussing, the primary and secondary would have to be close, as in elevated off of the surface. Probably no more than 5-8%.

The transfer rate and efficiency can be improved by coupling each inductor with a capacitor bank. By engineering the inductors and capacitors properly, the two will react as a tuned circuit. If it's running at 80-100 Hz, the practical limit, the transfer rate will improve because the frequency is higher than 60 Hz that line voltages operate at.

 

[Flying_Lavey]

I've said it before, and I'll say it again.....

The electric companies will offer to install a second car charging dedicated service (most already do) where discounts and all are available and will be marketed as you can decided when to charge to avoid peak times. Once many fo them are installed, that branch of the company will be broken off and it will then petition the PUC to not be under their perview as they technically are a commodity at that point, it'll pass because that is true. Then their peak times will be different and rates will be unregulated. Id put that time frame at 10 to 15 years at most.

Not at your house, The meter only measures total KWH - not the rate of delivery but there is premium for it at most 3rd party stations.

Charging off a 30 or 50 amp cpnenctor at home doenst cost any more per KWH than a 15 amp edison socket - the meter just spins faster, but the net consumed is all it reads out.

Until the increased kWh usage charging the EV puts the homeowners into the penalty usage category and they have to pay 50¢ per kWh or more. No one mentions that when discussing home charging in California.

Sure on a tiered plan if you start pulling into the 3 and 4th tiers your electricity will get expensive.

Someguys are on a time of use plan other guys on a tiered rate.

In a time of use plan you just have the car start when the timing makes it cheap.

As far as vehicke charging goes yes.

charging networks are setup to be able to tier the rate based on both KWH and AMps delivered to the charger.

It cost more to install and reliably feed a charger capable of 300 than 200 or 100 KWH hence you pay a premium for the (potential) speed.

The vehicles spend very little time at those rate anyway and usually fall down to the 50-150 range as the batteries fill up.

Electric Vehicles - Charging

There are three types of charging stations for powering up your electric vehicle. Stations with Level 1 and Level 2 speeds are available to residences and businesses, while Direct Current (DC) Fast Charging is typically only available at business sites because of the significant cost and power...

When I first saw it in March, I related it to fords version of the ranger. Some body features looked similar to it but obviously not the same truck. Some rumors of this being available in June of 2021 for $75k.
