SIMPLE BATTERY CHARGER
Posted: Tue Jul 17, 2007 6:45 pm
Hi!
Ive just made myself a controller for a charger that auto detects when the battery is at a preset voltage and switches off a charging circuit...
this all works fine with on board micro controller LCD screen...nice
HOWEVER... it basically opperates a relay that will turn the charging circuit on/off
I got a 1000 watt tranformer..... straight onto a bridge rectifier and then onto the batteries....
It gets hot quick!
the battery bank is 60volts
the 1000 watt transformer is 45volt+45volt =90volt
I guess the charging voltage is a bit high.... maybe
but my main question is this...
will this charge the battery ok.... a tranformer onto a bridge rectifier and then onto the battery?
or am I missing something? a choke?another diode? do I need a smoothing capacitor for battery charging?
thanks for your help
