Hi, everyone,
I've been considering a circuit that provides both backup power via a battery while charging the battery at the same time.
My current idea looks like the attached picture, using
1. a zener diode to keep the voltage capped at the maximum voltage of the battery
2. a current-limiting resistor to limit the rate of charging the battery.
I've yet to build up some strong intuition, so I'm hoping to know if there's something obvious that I'm missing, or if I'm completely off, and a project like this isn't feasible. The reason I mention this is because I've poked around through the internet and found many much more complicated solutions to charging a battery.
Thanks for taking a look, and I really appreciate any tips!
