Tesla pickup, possibly

My take on the Walmart electric truck idea would be to have a battery on the truck but a larger battery on the trailer that could be recharged when the trailer was at the dock.

Since Walmart sends the trucks to the same store with a trailer, and all stores are within a days drive of the regional distribution center, drop trailer and return with empty while the store crew unloads the trailer it could be recharging. So each store would have a charger and the distribution center would have one for the truck battery and one for the trailer.

A few years ago they were playing around with an electric truck with a large battery and a small high speed diesel that could maintain truck on the flats and the batteries would help out on the hills with regenerative brakes recharging on the downhill.

I'm thinking that since the stores are all pretty close together each one will be fitted with charging stations for each bay. The truck will back in to be unloaded while the driver plugs the truck in. While it may not fully charge the truck it could put enough extra charge into the battery so it can make it through the day. WalMart has a few advantages. First they can afford to pay for then take all the tax breaks to do it. They have lots of stores and depots so a charging station is not far away. They can afford to have spare tractors waiting at each store just in case one needs more time to recharge. But most of all they don't need to make a profit off of their trucks. To them the PR of going green can offset the added costs (installing their own supercharging stations at each store, the extra trucks, the extra batteries, etc.).

And that "bigger higher definition" one is hardly the current state of the art set...just like LCD and plasma went down when LED entered the market and it's been well surpassed...

Not to mention solid state hard drives. The cost per gigabyte keeps going down. So okay the current location of the goalpost is to mean 'brand new' technology is going to be more expensive and has surpassed the tech of yesteryear.

5 times would be good.

H-fuel cells have been around a long time...it seems they have had a lot of time to perfect them but for some reason they have not been able to get them safely usable for the average consumer level applications...but they would be an alternative to rechargeable batteries...

Yes, I think all those toys that use lithium batteries have had something to do with that. I've only seen fuel cells in use for building sized applications.

Couldn't agree more...toys are one of the most applicable uses for batteries...BTW...H-fuel cells seemed to have worked OK on the two passenger Gemini capsule...circa 1965-66...

Speaking of current weather conditions, Just what will these magic battery cars/PU's/Semi's do about heat or AC?????
My Chevy will get nice and TOASTY or COLD regardless of out side temp.
Maybe they could put a luggage rack on the back where they could put a generator to charge the batteries or run Window Unit Heatpump.

Use more battery energy making the limited range shorter. Maybe they’ll use diesel or kerosene for heat because electric resistance heat takes a lot of energy.

It was warm today up here in New England 15F wonder how long the battery lasts in this weather. Wonder if they fixed the battery drain problems in really cold weather when left unplugged overnight?

Most have a remote pre conditioning mode that will warm or cool as needed before unplugging and driving off.

Here is a Tesla Model X that the owner tested it's ability to warm the car in cold weather. from 21*F didn't take to long to get to 104* F then 108*F

starts off with funny scene, Bjorn testing his model X off road- where it broke body pieces off

math suggested 3-6 kwh to pre heat or 2 -4 minutes at a supercharger

That’s a nice feature, but it still takes a lot of energy to maintain a comfortable temperature with the outside temperatures at either extreme. My experience with cold batteries is they have a drastically reduced power output. Same problem with the car batteries?

Unless you're trying to break 0-60 records you don't need a ton of juice to cruise/accel. Our 85D tops out at 375kW instantaneous power at full throttle but doing 70mph on the highway is around 25-30kW.

It also spends energy to keep the pack warmer since like you said, colder batteries have less energy/power. 99.9% of the time I'm plugged in at home so the battery is already at a reasonable operating temperature. If it gets down to ~45f I can see some regen disabled(40kw of 60kw) until the pack warms up(~5 minutes).

As for cold weather operating ranges, I generally see a ~10% hit in range, mostly tied to wind resistance > 55mph. The internal heaters do take some energy but once it's warmed up doesn't seem to take much more. AC has even less impact on range, been quite a few people who camped in their Tesla and were able to run the AC for a few days. The difference between 65, 70 and 75 is pretty pronounced once it gets below 55f, although anyone who tows and tracks mileage already probably knows that.

Wow the Model 3 is capable of being used as a competitive Cannon ball run car?

Not competitive to cars that run on gas. The model 3 averaged 57 mph. It is impressive for a electric car, but the record is under 32 hours. So that’s an extra 18 hours in charging.

What amps do the quick chargers draw for Tesla

 

[vvanders]

Home chargers are 240VAC/30A-40A (7.5kW-10kW).

Superchargers are 400VDC/300A (120kW) at 35% battery tapering down voltage and amps as charge approaches 100%.

I'd take one if it did a 10 second 1/4 mile

Why did they put it up there?? It worked just fine sticking out of the floor for many years!!

Coal powered cars, Semi's and now Pick Up's!
Try running your Dryer all night and look at the electric bill! Then run it every night so you can drive tomorrow.
Of course the Government will give away electric to subsidize. Oh wait, that guy is gone.

Unless you live in Hawaii, electricity is cheaper (on a per mile basis) than gasoline.

Hawaii or PA...Ever see what we're charged? I'll stick with gas.

 

[joeu235]

We'd better start building a lot more electric power plants.
