An Iphone 8, now a relatively inexpensive model, can charge its battery totally in two hours’ time. There’s hardly at any time a want for faster charging, but it is honest to talk to – how much a lot quicker could it actually go? [Scotty Allen] from [Strange Parts], back just after a hiatus, is back to stretching the boundaries of what a standard Iphone can do, and decides to begin off with an exploration of battery systems.

What people today usually encounter is that charging pace depends on the charger included, but even one particular hundred chargers in parallel will not pace up this iPhone’s charging charge, so what’s up? First off, the phone’s charger chip and the battery’s BMS will both of those limit charging current, so for experiment reasons, those experienced to be bypassed. To start with attempt was using a significant DC electric power source with the primary cell, and, unhappy with the lack of fireplace and even now rather gradual charging, [Scotty] decides to up the ante.

There’s a handful of battery systems you could pair with a cell phone if your intention is to pace up charging dramatically, and [Scotty] demonstrates 1 of them in motion – for instance, Lithium-titanate batteries can acquire really a pounding when it will come to charging current, and they’ve assisted get the charging time down to 22 minutes. Nevertheless, which is no match for a supercapacitor pack, which the charging time down to nine minutes – a thirteenfold
