Hæ, ég rakst á Battery Equalizer / Battery Balancer á netinu í morgun og þar sem ér er með 24v bíl þarf ég að vita meira um þetta. Er einhver sem þekkir þetta dót og þá hvort þetta fæst hér á landi eða er þetta kannski eitthvað sem hægt er að búa til á rafmagnsverkstæði?
Setti copy/paste af þessu hér fyrir neðan, vantar að vísu skýringarmyndir sem eru á síðunni bus.getdave.com
kv BeggiA Battery Equalizer (a.k.a. „Battery Balancer“) is a simple three-wire device that keeps your batteries balanced:
Essentially it holds the middle wire at half the voltage of the outer wires. If one of the batteries has a higher charge, current will pass through the equalizer from the higher battery to the lower battery.
Most equalizers can also do plain 24->12V conversion and often 12V->24V as well. If it’s hooked up as an equalizer, though, then it will keep your batteries balanced even if you aren’t using the 12V circuit, which is good for battery life.
Equalizers have a max current rating, but that’s just the balancing max current. To use an equalizer you would still use the splitting techniques as above. This means that you can actually use more than the maximum equalizer current for short periods of time, as long as the equalizer has a chance to balance the batteries out afterwards. Furthermore, if you do a double split like above, then the equalizer only has to deal with the maximum current difference, so if you can mostly balance two circuits, the equalizer can make up the difference.
Side note: Most equalizers need to be connected/disconnected with ground wire last, or you can fry the equalizer! See your manual.
