Why Gas Engines Are Far From Dead - Biggest EV Problems

Quote

I have watched this youtube video and would like to share with you all!

 

According to the industry that is selling combustion engine, and the combustion engine is going nowhere.

So. . . let's dig into it and find out why is it so.

Why would manufacturers continue improving combustion engines?

So in the video, it is going to divide into 4 categories.

Enviroment, Science, Consumer and Cost.

And let's start with science.

From the physics standpoint, the biggest challenge inside an electric car is energy density...

How much energy can you put into a certain space...

image.png.c7474d59fdb638a994f1f066494f2f4e.png

So it illustrated that a gallon ( 4.5L) of petrol can generate 33.7kWh.

And to make his point clearer, Jason pointed out that just one gallon of petrol has even more energy density in a 1st Gen Nissan leaf!

image.png.99f01fe12e922187b578007c1b44dc05.png

And Jason found 8 lithium-ion battery manufacturer and check out who has the best energy density of a battery cell. And the densest he found is 684wh/

In the video, he wanna know how much space do we need to contain the same amount of energy density produced by petrol and compare with lithium-ion batteries.

image.png.d59a8adc849bdf203112ae130ee8b80d.pngArranging the can to match with one gallon of petrol. . .

And it takes 194 cans of soft drinks to make it equivalent to one gallon of petrol.

And by volume, it is 13 times more energy-dense than the lithium-ion batteries.

So moving to the weight factor, it gives the petrol engine more advantages.

1 Gallon (5.4L) of petrol weights 6lbs ( 2.72kg) = 33.7kWh

Wuy5pea.png

Petrol energy density = 12,400wh/kg

Li-Ion energy density = 240wh/kg

This is an astonishing 50 times.

One thing Jason point out that the reason why it doesn't make sense to make an electric plane powered by a li-Ion battery. You can pack all the battery to make the plane fly and don't travel long enough, yet you cannot carry any passenger with all the weight pack inside the battery.

Following is cost.

According to SAE, the initial purchase price of an electric car is $12,000 USD more than the petrol car.

Then it comes to profit to a manufacturer. An electric car in order to get profitable, it needs to cost $48,000USD.

So most of the manufacturer would produce what makes them profitable.

Next is the environment.

Q8KUQqn.png

There is a study shown that the is going to be roughly 2 billion more internal combustion engine to be produced between now and 2045.

And let's take a look at the manufacturer point of view.

Let's say you are Mazda who is a small car manufacturer compare to players like VW and BMW. They do not have a lot of money and so they have to spend wisely in their research and development budget.

So instead of producing EV car and the total sales is only going at 10%, making it 5% environment-friendly. The company can decide to spend all their money to make all their combustion engine car more energy-saving and better emission standard for environment-friendly.

So in this hypothetical scenario, it is actually more profitable and cleaner to make a combustion engine.

Finally, it is consumers.

A large part of selling a car is knowing the market if they were to purchase one. 2018-2019 the global electric car market share is about 2%.

. . .

Okay you should watch the video for a clearer explanation. haha.

The thing is if alot of country  start banning gas engines  car. Those  manufacturers got  no choice  but to change  also.

China and eu already  set deadline.

I think as and when USA become the 2nd largest economy of the world, the combustion engine will be going downhill.

 

Even the Saudis are diversifying the revenue from oil.

 

Do we remember solar which used to bulky and inefficient? We now can produce solar cheaper than coal generated power.

 

battery technology is playing catch up and when they can produce a battery like a printer size package that replaced today's lithium pallet, it will promote EV.

 

Every major manufacturer are having or planning a new production for EV cars

etc

 

 

fossil fuel is limited even with shale oil, alternative energy is needed

I scare some of the members here cannot play the video while at work.
