Battery Charge Management System (BCMS)

[nickb2]

So, since I am a beginner, I already know that @2volt, this may even cause damage.

But right now, I am not concerned with that. I am more concerned right now in how the leaf battery will hold up, seems like a winner so far, may even surpass expectations, maybe due to mix of carbon and graphite mix. It is all pretty much chinese to me right now. But I am getting a good look at it, even when I ask questions like this, to Nicholas Or Erick or Michel at school, they cant divulge certain things, cuz even they don't know.

Erick worked for tesla, he is so kind to come teach us. He is very skillful, but I must say, a quirky man. He got on a stint talking about when he was a ranger for tesla. I asked him, should I go work for them? He looked at me and said no, not with your type of personality, you have no idea the NDA's involved. SO I just winked.

If this forum goes into weeds, it will probably be my fault. But I will try to keep my personal life out of it.

I have been waiting for a long time for this.

Again, thx to Richard and billr, it is up. I just hope it will halt and catch fire. If not, lots of other EV car forums out there.

I am going to try something here, I don't know if it will work, but maybe I can finally use this function.

All the modules have a q code. All link to cool vids such as this one.

 

[nickb2]

Yeah, I took pics from book, they are in french, but gives a nice idea of what we can expect in class in futur. Very well made course in my opinion for the beginner. Which I totally am. The learning curve is ok, I feel comfortable so far. Just don't push me, I am not like the young bucks who gobble this in their sleep.

 

[nickb2]

Nickd does make a good statement, testing right now is limited, and our hands are tied to what we can use as fast in out tooling.

As someones else wrote here, my head is hurting, I need to bang my head for a bit and recoup. The scripting stuff I have been looking at is going to be a doozy.

 

[nickb2]

I would love to talk to an engineer of the volt, why did they feel the need to put in a auxiliary DLC?

Only car so far I have seen that has two DLC's for electric, might have to do with bandwidth maybe, I am on fence and don't know. But I mostly suspect that in future, we will see this more often.

 

[nickb2]

Sorry, have to correct, the tesla also has a aux DLC. But that one is proprietary, still working on script reading to make sense of it.

Could use solar energy to silicon photo cells to generate electricity to separate the water molecule to oxygen and hydrogen, leave the oxygen in the air and put the hydrogen in a tank, that is a heck of a lot cheaper and safer than using a battery and won't wear out. The effect on the environment would be next to zero.

Really stupid AH type of people relate hydrogen to the Hindenburg. First place the hydrogen bags were made from cow intestines, a lot of cow, the paint was highly combustible, that caused the major damage, hydrogen burning was straight up. But 62 people of the total of 97 people survived. In an airline crash, just about everybody is killed.

If a vehicle is hit with gasoline, that stuff spreads everywhere, my sister-in-law was burnt to death when she was alive, people heard her screaming. Hydrogen does not spread and far safer than gasoline. Also saw a 1000 gallon LP gas tank catch on fire, flame was over a hundred feet high, but safe in a few feet from it.

Also talk about hydrogen fuel cells, extremely expensive and not more more efficient than just burning the stuff. Turbo jet engines are far more efficient than internal combustion.

Another much safer fuel we have over a 12,000 year supply of is methane, burns much cleaner and it does deplete the ozone layer if not dumb, stupid, Al Gore and his followers knew that, and maybe the did, but cannot rob people this way.

The Paris carbon dioxide is one of the largest farces in our history. The cure is a carbon tax!

Another much safer fuel we have over a 12,000 year supply of is methane,

Plz don't get me started on methane. Taxing cow farts.

refound guy

 

[nickb2]

poker face or what?

 

[nickb2]

Ok, bcms, deformation sensors. Well, that just changed things, only kiaéhyundai thought of thisÉ

 

[billr]

Do you mean sensors in the battery pack to monitor how much the cells are changing size due to charge/discharge?

 

[nickb2]

yup,

 

[nickb2]

of all, the best design is by far the kia, again, ugly as sin. But once opened, you see the thought processes

I dare any one to try this

 

[nickb2]

Opened cells on 2 gen volts. Major design flaw, but that is expected. Bolt, saw that also, no where near kia.

Useless rambling as of here, of all the hybrid and full ev bat, the only one that made sense was the kia slash hyundai.

go figure.
