Battery based electric vehicles of today and tomorrow.

[Grumpycat]

CHAdeMO is rated for up to 500VDC and 125A, 62.5 kW. LEAF has a 400V nominal system for 50 kW. When Tesla built a CHAdeMO adapter they had problems with chargers not behaving per written spec, but according to what a LEAF would allow.

Tesla also DC charges are nominal 400V.

This is a screenshot of the a Tesla app during one of my supercharging sessions. Is running 115 kW at that moment. It tapers down to 60 kW or so with 200+ miles of range in the battery.

One of the large children's hospitals in our area put a remote location in a town near us where we often go for Dr. visits. They have charging stations all along the back wall of the building and the only vehicle I have ever seen parked there is an older Toyota Tacoma which I'm pretty sure is ICE rather than electric. I would think that at least some of the Drs. would be driving electrics.
I would really like to consider an all electric vehicle for my wife, who is due for a new ride soon, but all I have seen are low slung and I can't get out of them after I have to practically fall into them.

Very very rare to find a DC charger at hospitals or shopping centers. Tesla likes to install DC Superchargers at shopping centers were it is guessed they get pace fore free in exchange for brining premium clientele to bathe businesses. Heck, the business has to provide parking anyway, might as well be a Supercharger.

The EVSE (is not a charger, is only an elaborate extension cord) usually found is 208VAC @ 32A. About 6.6 kW. Is no better than nothing but only good for about 20 miles of range for an hour on my Model S. Not hardly worth the effort for only an hour.

Try a Chevy Bolt. It's sort of a micro-SUV instead of a passenger sedan.

The quick trip i12 miles away has a spot for electric cars never see any cars in the space that ate electric. I dont think this fade is going to take off like people think and this is the USA not Europe! Who cares what they do there!!

I agree we are a generation away in the USA. Lagging Europe and China may be a fact of life that never changes like with cell phones, etc.

It is kind of like automatic transmission are for girls and I will never have one statement of yesterday that some of us have made in the past. When new ICE's are not for sale any longer we will be buying EV's like we buy new pick up trucks only with automatic transmissions today.

EV's do not even require transmissions and traditional drive trains requiring 90% fewer moving parts/friction points.

Charging ahead at the workplace: How electric-vehicle stations can benefit your company

".....Ford Motor Company will introduce as many as 16 new EVs by 2022, including an all-electric Mustang-inspired SUV, and General Motors is planning on a future in which none of its cars are powered by gasoline or diesel. VW, Jaguar, BMW and Volvo have also announced plans to shift completely from combustion to electrics....."

I don’t follow your grammar. You say EV won’t serve for “quick” trips of 112 miles?

For 6 years I have jumped in my car on a moment’s notice for 150 mile round trip. I don’t even bother to charge more than 85%.

Aside from cars, has anyone looked into these vehicles: Solectrac Electric Tractors

$45k is too steep for me but as the tech ages and improves it will become cheaper. I realize a full time farmer would not use this but there are 100,000s+ homesteaders, mini-farmers, etc. who use their tractor <4 hours at a time.

A corded tractor..hmmm. Thoughts?!

Now that's really thinking outside the box. This caught my eye:

Researchers in Germany have modelled the pairing of additional units in the field in a daisy-chain configuration, covering larger acreages with greater efficiency for refilling in planter and seeders operations.

So only the tractor nearest the power supply needs the long cord, while other tractors can be daisy chained off that one to disk or plant running parallel to the first one. It says the cable sends 3 x the power needed by the tractor alone (and gives it twice the hp of the diesel version of that host chassis), while the extra power is available to drive a powered implement, or additional tractors.

Maybe the first use will be in fields already laid out in huge circles, already using center-pivot irrigation.

An interesting way to spend German government grant money.

The tractor has a 100kW drive motor and 200kW for powering implements and they run 2.5kV in the cable. To put in perspective as to how large your service drop has to be, 240V requires 1250A for 300kW. One needs 1500A (only use 80% for 100% duty cycle) service in the field just to power one tractor.

At 2500V they only need 120A in the wire strewn across the field. A flexible 1000m cable for 120A at 100% duty cycle is going to be at least $40,000. And how often to replace or repair from dragging it around?

This is exactly the kind of German Insanity one comes to expect.
