Hi all, I'm looking to get your thoughts and feed back on a project I'm currently constructing. I'm making a rotary self propelled sweeper and am using an old nicad pack I had from a previous unfinished project. It's a pack made of 160 Sanyo N3000CR Nicad cells. I made the pack from garolite tubes epoxied together and I'll be constructing a HDPE box for the enclosure for them.
My question is to charging these. I am going to have them as a 24 volt, 24 Ah pack. So we're looking at 20S8P. I know I cannot charge them as one pack, and have to break apart each of the 8 series strings and charge individually. My plan, which I'm not sure will work, is to have ( 8 ) 24 volt cordless tool chargers that are hooked up to each of the 8 series strings permanently. If I was to design these chargers to be on board the sweeper and hooked up directly to each pack would this create a problem? The idea is that I could connect all 8 chargers into a single strip to have one main plug to connect to an outlet. The pack would still be connected in parallel permanently and I don't know if this will pose a problem? Any help is appreciated. I uploaded two photos to show what the pack itself looks like and my current progress on the machine itself.
