I need a way for developing project for charging 4 12V battery of electric scooter from solar panel please suggest just for proto type model ....how it should be done????
12V AC or DC? 48V AC or DC? Please give all the details.
It depends on how much current you want at 48V.
If you want to convert 12VDC to 48VDC then use an oscillator at 12VDC that feeds a transformer then the output is rectified and filtered into 48VDC.
Instead you could use an IC designed to do it.
Yes i agree that 1 amp is not very much to charge a 18AHr battery. That's probably the absolute min required or something like that, so it could take a very long time to actually charge even though 18/1 times 1.5 is just 27 hours (a little over 1 day). It may take a few days to actually fully charge.
To find out, try charging it with a 1 amp power supply and see what happens.
But the sun brightness changes during a day. It is dim in the morning and evening but is the brightest at noon.
Unless it is motorized, the solar panel is not directly facing the sun all day, only at one time.
Clouds??
