I was just reading an article on electric cars, and got to thinking about how resistance drops when you wire resistors in parrallel.
Now I’m still a noob to electronics, so I have no idea if this idea has any merit, but the thought I just had now was this:
When you charge a battery, like say, one of those RC batteries… it gets really hot. And heat is generated when there is a lot of resistance and you’re trying to put a lot of current through at once. Batteries can explode from this heat, which I suppose, along with breakdown of the chemicals, may be one of the limiting factors in charging them fast.
So I got to thinking… Those batteries in the nicad packs are wired in series. The current has to flow through them all. If the batteries have resistance, that will add up. But what if the batteries were wired in parralel? Just for the charge cycle. Wouldn’t that be kind of like wiring resistors in parallel? And wouldn’t that lower the overall resistance to the current? Might that keep the batteries cooler, because battery #1 doesn’t have to pass all the juice for 6 batteries through it? And thus, wouldn’t that allow you to charge the batteires faster without breaking down the chemicals or risking an explosion?
I don’t know. What do you think?
