10 lip 2024 · The best way to make an alternator charge at low RPM is by changing the pulley size and installing a smaller pulley on the alternator to increase its rotational speed relative to the engine speed, and allow the alternator to generate more electrical power and improve charging efficiency, especially at low RPMs.
17 paź 2022 · One way to make an alternator charge at low RPM is by reducing the size of the alternator’s pulley. Reducing the pulley allows the alternator to run faster at the same speed. Even if the RPM is low at this point, charging will take place because the alternator is running fast.
6 maj 2020 · Hello. You could use a dc to dc boost converter. Of course, if you go from 12v to 48v , it is 4 times more, so you must divide your amps by 4. If it was 12V 100 Amps, At 48V, 25Amps. with the dc to dc 80% efficiency 25Amps x 0.8 = 20 Amps. Also, the alternator needs a 12V battery to excite the electromagnet of his regulator.
14 mar 2008 · Assuming your alternator is capable of making 60+V (you need 15v/battery), you'd set up a resistive divider using precision resistors, so the output is exactly 1/4 of battery voltage to...
13 kwi 2012 · the only way to really succesfully/quickly charge from a running engine is to connect a battery charger that runs off 12v- safely and correctly directly off the alternator and run that to the battery terminals so that the charger pushes constant amps to the battery irrespective of any current draw. this will force alternator to work above and ...
4 sie 2014 · Yes, a low RPM alternator can effectively charge a 12V battery, as long as it is rated for the appropriate voltage and current output. While higher RPMs may result in faster charging, a low RPM alternator can still provide a steady charge to the battery.
The WS500 is the only alternator regulator available that can utilize current, voltage and temperature to deliver the most precise and effective charging possible for 12V, 24V and 48V battery systems – with configurability for voltages in between – making it the perfect solution for charging lead acid based, or new generation LiFePO4 ...
