multiple alternator use
1 Attachment(s)
i was wondering is any of you could answer this question.
if put in the vehicle or in a tow along. couldn't you just recharge or keep the battery/s charged using simple alternators like a standard car does now? i.e a alternator for each battery and the alternator/s r powered by a separate motor(just 1 motor to power all (gas, diesel,or electric)) i search the internet and the forum but no one ever talks about using more than 1 to just keep charged individual battery's . the standard voltage regulators would prevent over charge...so i would think they would or could just run at a standard speed with no problem and keep batteries charged. :confused: |
Are you talking about keeping 2 charging systems separated so that 2 separate batteries can be used independently of each other? Several companies make solid state isolators for that, way simpler than using multiple alternators in an already cramped engine compartment High Performance 90-amp Battery Isolator | Overstock.com

yes that is similar to what I'm talking about. and that would even make less weight and load on secondary engine. also wouldnt using that keep you charged allowing higher mileage and would only limit you to the fuel running out(in the secondary engine) and then eventually killing the power pack.

in what kind of car or set up are you talking about ,an electric? a hybrid?

This pic reminds me of a picture floating around the interwebs where some guy installed four * 140A alternators in his pickup, to power his radio. That's about 7.8KW of power, versus my 1.0L hybrid's 10KW onboard generator. Anyway, he could use his alternators for regenerative braking. There's probably cheaper ways to achieve the same result, though. |
wanting to mod why not a generator powering a battery charger then?

the regen turns the motor into a generator during breaking, but it will absorb in the kilowatts of energy quickly! but the motor adds zero dead weight or drag because it also drives the wheels, if you are adding a bunch of alternators thats alot of weight and drag?
you will never come close to the effectiveness of the hybreds system, if you wanted to use the alternators to slowm you down by hitting a switch that would activate your feild windings that would present drag on a driveshaft and slow you down and also generate power, but i cant see it being a positive thing ( you\'ed lose more than you would gain,if i understand what you are tring to do. |
