To start, I saw a scooter electrics. In that implementation, after quite a weak (in my sense) generator it has some shunt linear regulator, that just dissipates overvoltage to heat. Oh god! Weak generator + such many losses + inability to carry electronics, I would never buy myself one! :)
Now consider I've bought some big car, and I am electricity geek, so I've somehow managed to install 480Ah*12V battery pack in it. I want to be able to run kind of welding, and have many electrical devices, but power consumers are not the case. Just appreciate it's somehow could be used, in a quite short time.
I feel that I should modify supply system in a first place. First step is ofc is buying a powerful generator, I'll accelerate slower, and would agree to waste some amount of engine power to charging, at its best! I heard car generators are 3-phase. Scooter weak stuff is 1-phase. But what's after? Generator is working at a quite random RPM, its rectified and voltage varies alot. What should I place after a generator between battery? Or how to design extremely-heavy load car charging system?
PS. Indeed a PC exists in that car. It could control and have to log voltage and current draw, so a subquestion is "how to measure current draw", when multiple batteries connected to some "distribution copper bar"? You typically dont want any bit of power loss, but have to measure aggregated current from all the batts.. but that's worth another question. You may just comment on that topic briefly, so that I could do my own research, and not flooding questions in here. Thanks!
