SA's electric car boom is coming

[itareanlnotani]

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

Regenerative braking: how it works and is it worth it in small EVs?

Ever since the first Toyota Prius rolled off the line over 20 years ago, the concept of regenerative braking has...

This says real world testing gives around 30% extra range, thats not bad

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.

It's not the imaginary route. You won't buy a fuel vehicle in 10 years time. SA doesn't and never will have an EV infrastructure.

Overnight Eskom uses the unused capacity to pump water up mountains to pumped storage schemes to release to generate power during peak time. There goes the power you thought you had...

 

[Cosmik Debris]

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

For an entire nation running on EV's?

 

[RonSwanson]

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

Kind of like a strawman argument, isn't it? No transition would happen big-bang style, and no-one here is suggesting it.

No, but that is under ideal circumstances. The battery gets less efficient the longer it is used. What is the efficiency drop off over charging cycles?

They've actually been using pumped storage during peak time, then supplementing with diesel (instead of gas, like they were designed for). ****ing Gwede could be adding more solar in 3-6months, but no, $$$ in pockets. Muppets.


I suspect SA will still see petrol car sales up until the 2040's.

 

[wingnut771]

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

No because the smart meter will wait for offpeak.

If you were to include the current pump-jockeys that would have to get a real job, maybe not, but they are dependent on pubic transport in anycase.

 

[itareanlnotani]

Most Lithium are 80% at 10 years with daily cycles.

The obvious thing is not to daily cycle. Which is why you need bigger batteries in cars, the less you cycle it, the longer they'll last.

Maybe if we stopped the child grant, that would improve.

Less new pump jockeys... (coming through on their parents pubic transport!)

 

[wingnut771]

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?

Eskom have 40GW 20GW available overnight to pump water.

 

[RonSwanson]

We have 10 years only...

The ANC is very good at meeting deadlines, just look at their Digital Migration
I see your point, but it does not address the point of this thread. EVs will come, demand for them will increase.

Electric vehicles are far from heavy adoption in SA. The cost of EV's here compared to the rest of the world is insanely high. Import tax is much higher than normal cars - 42% including the 'luxury' tax compared to 18% for regular vehicles.

That would make the price of the cheapest entry level model Tesla Model 3 about R1.2 Million compared to $45,000 in the USA or R3.9 Million for the Tesla Plaid S base model.

There should be an incentive to buy EV's not a ridiculous penalty. Many 1st world countries give rebates or tax credits if you buy an EV.

We would have perfected Fusion by then.

Yes, but here in SA, they won't be making $$$ on petrol/diesel sales, so they don't want many people buying them.

**** the planet!

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

Average person does 100km a day. A Tesla has a 500km+ range battery.

 

[Cosmik Debris]

No because the smart meter will wait for offpeak.

But Eskom is doing maintenance in off peak time so less is available...

Which will have to become - EV?

True, might even spark a "classic car" industry (service and spares), Cuba's already got the Vintage and Veteran market covered.
