Hi guys, I am new here. FYI before I get started, I am not an engineer, designer, programmer, or anything of that nature. I’m just a dude who loves a challenge, and I love diy home projects. Now, I hope this is the right forum to ask this kind of question!
So let me get started:
I have lately been thinking of a way to create a charge limit on my iPhone, because I try my best to limit degradation/long term damage of the battery. I have read articles and found that the lithium ion battery in your phone shouldn’t regularly be charged above 70-80ish percent, and certainly couldn’t be stored that way.
I try not to put my phone on the charger at night, as leaving the phone at 100% for a few hours over and over each night will eventually degrade the battery further. I also try to keep my battery in the 25-75% range as letting it die is also not good for it. This is pretty inconvenient, so I have thought of a solution. My idea is to create a small USB flash drive sized device with a male to female usb input/output. This device would plug into your phone’s power cube, and then you would plug your charging cable into the other end of the device.
I would implement Bluetooth so that the device can connect to your phone and know when your charging limit has been achieved to cut off power. It would also sense the internal temperature of the phone and cut off power if the battery temp gets too high during charging (heat and Lion batteries=quick degradation).
I have no idea where to start with this, so I figured I’d ask someone who knows a lot more than me! I am curious if there is a good (cheap) board/chip to use that can be connected to the phone via Bluetooth that is around the size of a flash drive. I need to be able to program it to perform these tasks. I am also trying to think of a good circuit for this design. For example, the board/chip would have to toggle some kind of switch/gate when either charging level is achieved or temperature is too high, and also be able to toggle the switch again once temps decrease or charge level decreases by a certain amount.
know this all sounds quite complicated and messy as I don’t know electronics terms/lingo, but it’s just a start for me and any help is appreciated! Gotta start somewhere, right? I’m just asking for input and ideas!
