Battery based electric vehicles of today and tomorrow.

[Larry Caldwell]

We’ve been told the worlds going to end in x-years since the early 70’s, and it hasn’t happened, and it won’t happen, but now we’re forcing an enormous expenditure

That take is fossil fuel industry FUD. What they planetologists have said is that we have 10 years to stabilize atmospheric CO2 if we want to limit global temperature rise to 2.5 degrees Celsius. We're already at 1.8 degrees. It was the oil and coal producers who churned that into the EOTW nonsense.

Oh boy

Yeah, park it outside in the driveway and charge it during the day so the fire department can get to it faster while they can see better.

You know 95% of Post Office mail carrier trucks drive less than 40 miles/day on their routes? Or think about how regenerative braking would benefit the repetitive start/stop duty cycle?

I saw an article about a company developing wind-up spring technology for garbage trucks. The idea is to let the spring stop the truck then assist getting it moving again.


Research "dog mode" and "camp mode" for Tesla to get an idea of how little is consumed running the HVAC. Police cars and ambulances spend 7 of 8 hours/shift idling. If one really feels one must keep the battery topped off then at idle a little 120VAC 12A connection will more than power the HVAC and vehicle.

Far fewer police are on the street at night than during the day. Patrol is a low-speed low-energy consumption mode compared to interstate speeds. As covered above, an EV is much more efficient at idle than an ICE so things are equally better at low neighborhood patrol speeds.

Around here officers are assigned a vehicle which they drive home after the shift. That could be a problem if they are expected to charge at home. Officers take better car of a vehicle they drive home than a pooled vehicle.


Anyone who thinks one EV is charged during the day totally negates the fact 97% get their charge exclusively at night is delusional.

With T.O.U. billing (used in locales at risk of daytime brownouts) it may cost 5x more to charge during peak hours than at night. If that is what you have to do then that is what you have to do. But that is something most will make great effort to avoid.

Yup, I've often charged during the day. Arrest me.


You forget the purpose of modern government seems to be to recklessly spend money to profit political donors, sponsors, and special interest groups. You are fighting against the symptom not the cause. The cause is ever-expanding government which needs to be stopped.

Lol
That I gotta see. A wind up trash truck. I pity da fool gotta drive that psycho nonsense.
Some people need to get up from the computer and see the world through lenses other than the ones they wear.

Speaking of climatology nonsense, Leonard Nimoy narrates in 1978.

Well it looks like it's going to be global cooling instead of global warming.

Is it ironic that someone in a Combustion Engine (fire truck) drove up to put out a fire from an electric vehicle?

Anyway...Lithium Cobalt batteries just aren't safe enough or effective enough to be put in cars. Their fuel density sucks compared to gas/diesel. They discharge faster in cold weather. They charge slower in hot weather. We need better energy storage technology. Li Co is just a stepping stone...and not a great one.


This is exactly the issue with EVs. They are worse ICEs in just about every way except they don't produce CO2 directly. Autopilot? That can be done in a non electric vehicle, and it is not close to being ready yet. Nice big computer screen in your car? So you can take your attention off the road....

Not impressed yet, but I do hope I will be someday. The only real cool EV benefit over ICEs I have seen is the Ford Lightning 100KWH battery being able to run your house if power goes down. Now that is cool. However if they are using Li Co batteries get ready for some explosions!

LOL so we fixed this my escalating CO2 emissions...but went a bit too far..classic!

I’m freezing to death as we speak! Snow tomorrow! Lol

But their figures thay show you can run a house for 3 days is pure bs. I install generators for a living and know just how far 100 kw go in the average home.

and with some cities mandating fully electric homes.....maybe it will power house for a few hours. Then you in the dark with a dead car battery.

Like that one......unfortunately all my rigs are white

 

[MossRoad]

Hahahahahahahaha. NICE!!

I use about 12 KW per day of power. It would power mine for days. However I make my own power so I know how precious it is and don’t take it for granted. it is absolutely doable but yes attitudes and home efficiency would need to change tremendously.

 

[MoKelly]

Yeah, just as the municipality pays for the police cars, they'd pay for the chargers. That's a fact. However, if by some means, the municipality could purchase EV cop cars, chargers, etc... and save the public money on reduced maintenance and reduced fuel usage, then it's a win. If it costs more, it's not. Put it to the bean counters and see if it pays.

They'd also have to figure out how to meter the chargers at the homes to pay for the electricity.

If police get to take company cars home and use for personal business, is the value included on W2’s like private businesses?

What do you live in. .... a shoe box. Thats like 500 watts per hour. A refrigerator takes more than that. Are you solar?

I get a kick out of the old Andy Griffith shows where Andy, his girlfriend, Barnie and Thema Lou would pile into the Ford squad car to go to a dance or something. That is unlikely these days.

Personal business? Elaborate please. Do you know if they are on call?

There are many AC refrigerators these days pull around 1.2 kw per day. You just have to look for them. Energy star.gov.
Yes I am off grid.

 

[grsthegreat]

I can see that kind of power use if your off grid. But im not sure you could charge a ford lightning offgrid. They say it requires 80 amps of 240 power for 8 hours to fully charge truck.

I had a lying, skunk smelling piece of carp BIL that was never on call, yet he took a patrol car home every day for years.
