SAP BrandVoice: Seven Reasons Why The Internal Combustion Engine Is A Dead Man Walking [Updated]

Yes they say it may be 2025 before the EV is cheaper than its ICE cousin.

The fact remains many retired persons have more vehicles than they can ever wear out before they lose the right to drive. The self driving vehicles will help us from losing our driver licenses.

the price of electric to charge those batteries will kill it..

The future is going to be interesting!

How much is it?

How much is it?

where I am, it's $.18/KWH. so if the charger is 50 amps at 220V, that's 11 KW per hour of charge, I imagine it takes a lot longer than 1 hour to fully charge the batteries at that low rate..

a lot of money and power in getting everyone scared via promoting some dire threat. Then to just happen to come along with a solution for that same dire threat, for a modest fee.

Just saw that a city in Calif was thinking of paying 1.1 million for en electric firetruck..... goes 18 miles between charges.

Electric fire truck was set to operate in Menlo Park, California before being vetoed - Business Insider


their tax dollars at work. i wonder how many REAL firetrucks you can buy for 1.1 mil


then again, heres another article that lists the price at 6 million? who knows
This $6 million electric fire engine is coming to the US - Electrek

According to the article, they did NOT buy the truck. The idea was considered and vetoed.

Speaking from ignorance?

Is easy to research power consumption of EVs. The EPA's website Fuel Economy estimates high, contrary to their gasoline/diesel MPG ratings. My old 2013 Tesla Model S 85 power hog is rated 0.380 kWh/mile as measured from the 240V 40A outlet. 40A is all one can draw at 100% duty cycle from a 50A nominal circuit.

Now I know in this modern computerized TV-fed generation that math is impossibly hard. If there isn't an app, you can't do it, so I'll do the math for you and show my work.

My electric rate is essentially $0.10/kWh. That is to draw 1000 Watts for an hour cost 10¢. My car will go 1 mile on 380 Wh. Note I'm freely flipping between Watts and kiloWatts.

0.380 kWh at 10¢/kWh is 0.380 * 0.10 = $0.0380 per mile. In the expression: kWh/mile * $/kWh the first kWh is canceled by dividing the 2nd kWh into it leaving $/mile.

If gasoline costs $2.50/gallon then for the same cost as a gallon of gasoline my Tesla will go $2.50/0.0380 = 65.8 miles.

At $0.18/kWh others mention: 2.50 / ( 0.18 * 0.380 ) = 36.5 miles

Or at $4/gallon: 4 / ( 0.18 * .380 ) = 58.5 miles

The Tesla Model 3 gets 0.260 kWh/mile, significantly better than my S. I'll let you do that math.

I was going to ask, how much is it, but it looks like Grumpycat did it for you.

Unless the Almighty adds some new elements to the periodic table . There is no new battery materials and tech in the future .

So far, the Almighty hasn't been able to stop the march of technology.

Then why can't we fly airplanes 10X the speed of sound ?

Yes but new elements are not what has driven battery (or motor) advances.

Even today's lead-acid batteries are better than those of 10-20 years ago.

Electric motors are already 95 percent and better efficient. The batteries are the lacking part.

the Tesla Model 3 has 100KWH batteries. so, to get a full charge, you need to put in 100KWH of charge, plus losses, so, .18KWH X100=$18 per day, so $18 per day= $540 per month of electricity being used!!.. and you don'
t think that's crazy?..

I expect you know your post is misleading mixing religion and science.

As of today not every element on the periodic table is used to make lithium ion EV batteries so there is room for new battery materials in the future.

Because 5x is all the effort we wish to expend.

You are terribly incompetent at math. By your logic my F-150 holds 23 gallons and at $2.50/gallon that costs $57.50/day to fill! $1750/month!

Model 3 has 75 kWh of usable battery.

but you have to recharge a Tesla every day. I fill my truck once a week or less
