SA's electric car boom is coming

[Cosmik Debris]

Now you're just grasping at straws.

I am? Despite having been in charge of electrical plants?

 

[wingnut771]

Nope. It can be used so long as you don't go below 20% which will kill it and ensure you charge to about 80%. Ever heard of de-sulphation, equalising and conditioning charges? Something car owners don't do but industry did when there were EV's in use running on lead acid batteries.

These were done manually. The only difference with EV's is that their charges and battery characteristics are now in a programme and lithium doesn't sulphate.

Are you starting to see that I may have worked in this field?

 

[Cosmik Debris]

I would assume the same time as the generator becomes a motor.

Is it more efficient pumping or generating considering the design of the vanes and the force of gravity?

 

[wingnut771]

So no switchgear, transformer, line, preventive or other maintenance in winter then?

We are talking coal power station maintenance. Eskom/municipalities don't do that other stuff anymore, just wait for it to break then replace.

 

[wingnut771]

But desperately want to believe commonplace EV's will work in SA?

Are we not allowed to dream?

Page 3. Bothered using search or are you just trying to get your post count up?

If you reference me something, you tell me which page. I don't search.

Talking about getting post counts up, why aren't you posting duplicates in the unfunny pictures thread?

 

[Cosmik Debris]

I didn't bother reading. You're referencing Gel where I'm talking about lead acid - sulphuric acid. Which is the cause of sulphation. Which you mentioned...

I'm a realist. Too many shattered dreams have made me a cynic.

Thanks might do that even my duplicates are getting likes...

Eskom has instituted a catch up maintenance programme. If they left it to break, there would be very little capacity right now.

 

[RonSwanson]

No, but maintenance of infrastructure, controls, switchgear and transformers do. You can't work on that stuff live. The turbine can be left spinning at low power consumption with breakers open to do that.

I don't think that they do that at Eskom.

You get 3 types, flooded, AGM and Gel.

They do. There is a catch up maintenance programme in force at present to catch up on 20 years of no maintenance. Try no maintenance on your car and see how long it will run.

Exactly. And I referenced the lead acid of yonks ago and said so.

On power stations yes, not switchgear and substations like they used to in the old days.

So you don't even need to change the water absorbent crystals in the transformer breather when they change colour? What happens when you don't do that?

I'm not disputing that they need maintenance. I'm just saying it doesn't get done. There is no word for maintenance in Pedi.

AGM batteries are far less likely to build up sulphation:

6. They are unlikely to build up sulfation

Sulfation is the property of lead-acid batteries, where there is a gradual accumulation of lead sulfate crystals in the cells. In most cases, it is the cause of failure in lead-acid batteries. Sulfation mostly occurs when the battery is not fully charged, and thus the crystals continuously build up on the plates. When this process goes out of hand, it prevents the efficient conversion of chemical to electrical energy. Therefore, for other types of lead-acid batteries, it is essential to charge them every six months to prevent sulfation. However, in AGM batteries, sulfation is significantly reduced. Therefore, they can be stored for extended periods without needing a recharge.

Absorbent glass mat batteries (AGM) have been a market favorite for the past few decades. At the time, they were designed to be a viable alternative to the

Remember me mentioning conditioning, desulphation and equalising charges?
