SA's electric car boom is coming

[RonSwanson]

And if every home that has a fuel vehicle were to plug in an EV right now?

Those are the ones that need to plug in after 22H00 at night.

The smart meter would either charge it or feed the grid.

So we wouldn't have a greater load shedding stage if everyone plugged in their EV to charge it right now?

To the few that can afford them...

More people can afford solar, than can afford an electric car here at the moment.

 

[Cosmik Debris]

How come?

Economies of scale.

 

[Cosmik Debris]

Me.

Next question.

Sure. But when the economy collapses because the others can't get to work, what happens to you?

 

[itareanlnotani]

So we wouldn't have a greater load shedding stage if everyone plugged in their EV to charge it right now?

Wouldn't make a blind bit of difference. I believe its 600 EV's total sold in SA. + some assorted Hybrids.

Given probably need between 10-15KWkr of power, each, so thats basically **** all.

 

[RonSwanson]

To the enlightened few that can't afford to live without them...

FTFY
My work requires reliable electricity 24/7

EV's are being touted as the norm, not only for those that can afford the higher end. So, how many can afford an EV and a home PV system big enough to charge it?

The norm being touted includes an electrical grid with capacity to charge such EVs off-peak. But, for those who wish to, I'm sure plenty can afford an EV vehicle and home PV setup especially if you consider the upward trend in Eskom & Petrol tariffs and the added benefit of being self-sufficient.

Those are the ones that need to plug in after 22H00 at night.

So the pumped storage schemes of Eskom won't be able to pump water to the upper dams after 22:00 for release to generate power during the peaks due to all the EV's charging at night?

If everyone switched to EV and used solar to charge, then government would probably introduce a solar licence for using the 'South African' sun.

You still lose out due to efficiency losses. Even on a fuel car you use more on mountain passes than on flat roads with your foot off the accelerator going down...

yes, but you don't store kinetic energy on a fuel car.

 

[Cosmik Debris]

More people can afford solar, than can afford an electric car here at the moment.

Can they afford a solar system capable of charging an EV at night or on a rainy weekend?

 

[RonSwanson]

Economies of scale.

That's so 70s, today we have a global economy (Cubans excluded).

I said if every fuel vehicle were replaced by an EV...

 

[wingnut771]

I predict electric cars will never work in SA, because criminals will target them to rip out the batteries to sell on the black market.

BS.

 

[itareanlnotani]

I said if every fuel vehicle were replaced by an EV...

If we're going the imaginary route, then by that time, Eskom should have installed more capacity, or at least given up and let the private sector install Solar, Wind and other cheap generation.

Current generation would be sufficient if they charged over night too. Our nighttime load is half daytime, we have plenty of excess.

 

[Cosmik Debris]

yes, but you don't store kinetic energy on a fuel car.

Of course not. but the gain isn't much on an EV.

 

[Cosmik Debris]

That's so 70s, today we have a global economy (Cubans excluded).

South Africa is still stuck in the 1 and 2 IR. That's pre 70's and it's not going to get any better...

 

[RonSwanson]

There is still PLENTY of capacity in the evening and early morning.

 

[Cosmik Debris]

BS.

Tell that to the cellphone tower owners...
