SA's electric car boom is coming

[SauRoNZA]

That torque has to come from somewhere. The math will show a faster depletion of the battery.

And your point?

This is the same for Internal combustion vehicles and the effect is much worse.

 

[Cosmik Debris]

I never said it’s prepared for everyone switching to EV’s by tomorrow, that’s not realistic on any level for anyone using their brain.

You said there will never be infrastructure, but there already is regardless of what scale it’s at.

So there will be electric capacity to support a nation of EV's then?

 

[SauRoNZA]

So, how much does the guy in the R30k skedonk get into the EV market? And he can't afford a PV system...

The 30k skedonk isn’t a 2021 model is it?

So the very same way he got into a 30k skedonk now, he’ll get into an electric 30k 10-20 years from now.

That doesn’t change in any significant way.

 

[SauRoNZA]

So there will be electric capacity to support a nation of EV's then?

In 10-20 years? Yes.

 

[Cosmik Debris]

And your point?

This is the same for Internal combustion vehicles and the effect is much worse.

Exactly. And ICE's use more fuel. EV's use more battery capacity. You don't get free energy just because it's an EV with greater torque...

 

[Cosmik Debris]

In 10-20 years? Yes.

Where will that electric capacity come from and who will afford to use it?

 

[SauRoNZA]

Great. I've done that trip many times from Okavango interchange to Cape town. What time are you driving and how long does the 30 odd km take you? What longer distances do Gauteng do?

I don’t drive, I ride.

Point is it’s the further extreme and it’s a mere 70km round trip.

People up north do well in excess of a 100km or more and smile about it like it’s nothing.

Cape Tonians are notoriously lazy about covering distance for work or any other driving activity.

You can happily do a poll on the forum and ask for a second opinion.

Nobody said it was free, but it’s much more efficient.

In the same way a diesel gets more kilometres per litre than a petrol because it has more torque.

EV > Diesel > Petrol.

If you're riding you're not stuck in the traffic. You haven't answered about times you commute. How long do you think the morning commute from Okavango to CBD in a car takes?

 

[SauRoNZA]

Where will that electric capacity come from and who will afford to use it?

Public Sector, Private Sector. Car companies, third parties with an interest etc etc.

Where does infrastructure normally come from?

All those people same companies building Petrol stations now will seen start ramping up to do their own PV production and offer charge points for electric vehicles.

EV > Diesel > Petrol.

So, according to you, torque is what saves energy?

And where will the charge points be powered from? Were you load shed this weekend?

You're unaware a vehicle uses more power on a mountain pass?

Short distances you say? Seen the traffic jams from Fish Hoek to Cape Town? Or Kraaifontein to Cape Town? Or Blauwberg to Cape Town? Or from Stellenbosch to Cape Town? Or the N2 from Somerset West to Cape Town?

Looks like you haven't driven much in Cape Town's surrounds during peak hours, which are a misnomer as most of the day is a peak hour. A single accident can cause a 3 hour delay with everyone trying rat runs through suburbs.

And all of those back in the afternoon? Traffic on the N1 in the afternoon only starts thinning around Klapmuts. The R300 and Okavango Road intersections on the N1 are a nightmare

That whole essay indicates time not distance. Electric car uses almost nothing in traffic.

If you're riding you're not stuck in the traffic. You haven't answered about times you commute. How long do you think the morning commute from Okavango to CBD in a car takes?

what does it matter how long it takes?

 

[SauRoNZA]

It doesn’t matter.

Your point was about distance. I said that is incorrect and it’s all about time.

I agreed with you from the start it takes forever, but that’s because it’s bad not because it’s far.

It takes me all of 25-40min depending on what music is playing and marginally depending on the weather.

In the car I would reckon an hour to 1 1/2 on average.

Still have no idea how it relates to anything. This is going to be the same in a petrol, diesel or EV. Only difference is the EV doesn’t lose charge idling.

 

[wingnut771]

So, according to you, torque is what saves energy?

Diesel is more energy dense than petrol

 

[SauRoNZA]

And where will the charge points be powered from? Were you load shed this weekend?

From the PV systems they will be building.

Most of the existing charge points in SA run independently from PV right now.

I was load shed this weekend. Again, how does that relate?

Here and now is not the future.

 

[SauRoNZA]

So, according to you, torque is what saves energy?

It doesn’t directly save energy. It uses energy more efficiently.

The energy needs to be used regardless, nothing is free.

More torque for less energy means a net capacity of energy remains.

So yes, more torque, uses less energy, adds more range.

{Ignoring weight and aerodynamics of course}

But I’m no scientist.

So, how much does the guy in the R30k skedonk get into the EV market? And he can't afford a PV system...

Like with most things, he "acquires" it over time. Ever noticed how many shacks in informal settlements have DSTV dishes? They aren't there to keep the rain out. The signal that they receive gets descrambled by the DSTV decoder (subscription either paid by a child grant, or fiddled by an internal agent ) and presented on a 60" curved UHD screen acquired during the riots, powered by a bridged prepaid meter. South Africans might not be affluent, but they are very creative problem solvers.

 

[Cosmik Debris]

what does it matter how long it takes?

Ever sat in a traffic jam and moved 5 km in an hour?

 

[Cosmik Debris]

Diesel is more energy dense than petrol

Correct. That's the reason for more fuel efficiency, not the torque as claimed...
