I'm talking about the BMS(battery management system) on the battery. What you said there is correct, you have more experience in this than I do. I only know some of this stuff for more than a week now, so not pretty sure how the wholse system works.

Why does a mild hybrid electric car uses a conventional charging system of the 12V supply system(meaning a 100% charging of the battery), and not a smart system in order to manage the charge and discharge of the battery?

Yes, this is true. I'm new to hybrids and studied metallurgy in the past. If a had more knowledge, I wouldn't ask for help here. Can you help me with this topic or are you just showing off here?

This I don't know. I think they recharge with more than 12V, getting energy from dcdc. I was thinking at 100% because gets the energy directly from other source, so no need for battery energy management, so every time it charges to 100%. Does this makes sense?

Mild hybrid cars use a dcdc converter in order to supply power from 48v to 12v battery.

Hi guys. I'm new to hybrids and was wondering why the 12V car battery in MHEVs doesn't need a smart battery system, and it's ok to always charge the battery 100%.In ICE, conventional cars the battery is maintained at 80%, but don't know for mild hybrids is ok 100%. Thanks in advance!

What you said, is correct Terry. But the process is like 20-30 years old and the temperature I think it's good, maybe needs a little optimization. Only sometimes this problem occur. Now engineers are investigating the problem. When I'll have more details, will let you know. I hope tomorrow...

It's not cooled.

tbuelna, it's not a cut made by sawing, it's a mechanical process made by a guillotine. racookpe1978, I think you're very accurate with what you said. I informed myself a little better about the problem. When the guillotine makes the first "cut" , it goes blank 3 more times(it's idling) without...

I can't see very clearly, but I think so.

racookpe1978, it's not cast metal, it's a solid metal, that's heated by induction and then cut. I thought about lubrification but need to investigate the problem more. Thanks guys.

Hello all. I have a problem where I work and want your help. At forging, when the steel bar is cut, sometimes the bar sticks to the "cutting blade". Then, it takes different shape than the normal one and a defect appears. The process is mechanical, no cutting disc is used. It's like the bar...
