Apple & WindWalker
You always aim for the perfect setup, right? Iāve been building a small solarāpowered gadget that could keep your battery at that sweet spot. Curious how it might fit into your ecosystem?
Sounds neat, but youāll need it to communicate over USBāC, support fast charge, and not interfere with battery health algorithms. If it can match the M1āstyle thermal management and Appleās energy efficiency standards, Iām intrigued.
I can get the USBāC side right, no problem. The fastācharge specās fine, but matching the M1ās thermals? Thatās a different beast. Iāll use a copper heat spreader and a lowāresistance path to keep the board cool, but the whole batteryāmanagement firmware still needs to be in the chip, not the cable. So I can do the hardware, but the software side has to be handled by the device itself. Thatās the deal.
Cool, but remember the M1ās thermal control isnāt just about a copper spreader ā itās also a softwareādriven algorithm that balances power and temperature in real time. If the device itself canāt run that, the whole system will feel sluggish or overheat. Maybe test with a realātime monitoring chip first, then see if you can push it into a fullāstack solution.
Got it. Iāll pick a lowāpower realātime monitor, wire it to the USBāC path, and hook it up to a quickālook interface. If the readouts stay under target, weāll see how the heat spreads. Then weāll feed the data back into a tiny firmware loop to keep the board cool. That should let us try a fullāstack approach without overloading the charger. Let me know what you think.
Nice plan ā keep the data tight and the loop tight. Just make sure the firmware loop stays below 10āÆms so it wonāt lag the main CPU. If it runs smoothly, weāll have a prototype that could sit in my powerābank stack. Keep me posted.
Sounds good. Iāll size the loop to hit 10āÆms and run a quick test on a lab board. If it stays under that, Iāll push the design to the powerābank stack. Iāll send the specs when theyāre ready.
Great, keep the specs clean and the thermal budget tight. Let me see the numbers and Iāll doubleācheck the batteryāmanagement fit.
Iāll lock the specs in a oneāpage sheet, keep the thermal budget to under 5āÆĀ°C rise, and include the 10āÆms loop timing. Youāll get the numbers by Friday, then we can crossācheck against your batteryāmanagement logic. Stay tuned.
Got it, looking forward to Fridayās sheet. Iāll review the numbers and let you know if anything needs tweaking. Stay sharp!
