I'm working on what is becoming an eternal project of a multiple port
battery charger. I have come up with some methods to do what I want but
thought there might be a better way. I want to have 1 charge circuit and 1
discharge circuit and share them among multiple batteries. Double pole
relays would do the job but I would like to use solid state switching
instead. Do you know of a solid state circuit that would allow me to switch
different batteries in and out of the charge circuit. The problems is that
current needs to flow both directions and I need very little voltage loss
(will discharge down to <1V). I need something like a power version of an
analog multiplexer or a solid state relay that behaves similar to dry
contacts. Or, perhaps you have an idea that would be or might be better?
