Grid charger

I haven't charged the battery in a while due to daughter having the car and me not being around. Took a few months but the IMA light did come back on. I charged it couple times and it went back off. Since it is a "dumb" charger I can't just leave it on overnight, have to monitor the battery voltage to watch for the drop.
I got most of the parts from Digi-Key. The power supplies were not going to be in for a few months so I did a search on e-bay and found power supplies.
I have another Civic I am going to be putting on the road soon and need to start charging the battery's on that. I think it will work out pretty good.

What voltage power supplies did you use? And did you just put them in series? I have been looking online for plans and such, but with no luck. I want to build my own geid charger, not really for cost savings, but just to say i did.

Smile Grid Charger

The power supplies are 48v and there are 3 of them. There is also a constant current supply that is used as well. I found the schematic on the 99mpg site, Here is the link:http://99mpg.com/Data/Resources/down...dchargerv1.pdf
There is a ton of great info on all these sites. I learned quite a bit about the 2003-2005 Civic Hybrids searching around. I didn't use the 12v supply as the Civic uses a special fan. Was going to put a 110v baker fan somewhere but haven't found good spot. Usually only charge when is cold out. I did use an old hair drier with no heat and pulled the fan boot off the car. I'm not at my normal computer so not sure what other files I have. If you need other info you can PM me or post.
Glad I am able to help.
