All new design with intelligent control
#1


I've been pondering a new design for my packs and wanted to start this post to track the build as it progresses. Not just adding a brain, but the whole design is fresh and new ( and may fail too). Here's a few pieces of the puzzle that have arrived lately: a handful of clone Arduino Nano's, NCH Power mosfets, resistors,relays, LCDs, and the TP4056 IC's (roll of 100). Still waiting for a couple more items to get here. This pack will not be like anything you've seen built before, I promise. I am considering making videos as well, but I haven the decided yet. If there are enough people interested, I would consider the video (but it's a lot of work and I don't want the video to be more important than the project). Hope you'll follow the build with me.cheers

Nice project! A good start is just images and text. That will give more information as start Smile

looks like you want to build something for charging/discharging... a new battery tester? I'll follow and maybe can contribute some brain and work, too Smile . For the displays, I'd use nice little OLEDs like the SSD1306 with I2C bus, for example. Easy to program with Arduino and you may even show graphs on them.

curiously watching your progress Smile

Definitely watching here, too. I'm planning on a different pack design, as well. Each pack will have it's own 'duino (of some sort).

Looking forward with what you come up with. Btw, I'm definitely a video watcher. I can get a better grasp of whats going on when I see the videos Smile

yes, me too Big Grin . Temp control with Arduino and multiplexer for up to 64 sensors, cooling and automated emergency cut-off. Want to put all this together in a case as modules...

We need what you say. We are watching with interest

A suggestion
Can it be triggered for emergency shutdown when this battery monitoring device warns when it falls below the specified voltage? buzzer signal

I have some of those, never got them to work with my 7s configuration... from my experience, they only work with up to 6 cells in series. And in addition, they're not very accurate. But as far as I remeber, they have a trigger pin for alarm, so you could use them with a relais to do whatever you want.

I'll be watching - videos or not. Put some blinky LEDs on there to really keep my attention  Wink

Thanks to everyone for interest. I have been working diligently on some code while waiting for the rest of the mail to arrive. I decided I will film the project and post them as I go. I'll link it here when the first video is up, hopefully within a week.
