Everyone is familiar with smartphones and other smart devices.

We need to create a vision, or industry standard, for high-performance
battery technologies, like Lithium Polymer, that includes a thin-film chip-set
that fully and automatically manages the health and use of LiPo's.

On the opposite side of this thin-film chip-set would be a 2-bit display that can
be seen through the shrink-wrap package that provides full information about the
battery's health and use. It might have a low-power Bluetooth capability to
communicate its status to the parent device. The chip-set and screen would be
powered by the battery itself, and it would “beep” very loudly at us when it needs
our attention; like when it need to be "fed."

Wot like this

But embedded

Hi Hamilton,

     Apple laptop internal batteries and chargers communicate with the macbook pro about their state and in fact are equipped with processors that allow this, the chargers have a serial number and comms with(about this mac when queried..)

and the batterys are smart enough to have passwords as detailed here http://arstechnica.com/apple/2011/07/how-charlie-miller-discovered-...


Yeah, sort-of....this example is going in the right direction. But I am talking
about a thin-film processor and display that is built-into the battery. Also, it
would use the battery's own power to keep the battery from freezing in cold
temperature and use its last, dying voltage to scream-at-me,
"I need power"
before is discharges to the point of no return.

hzl:   the "arstechnica" video is an excellent primer for this discussion.
I forgot to mention that my idea for this discussion was inspired by the
Battery Dioctor app on my iPAD while examining the LiPo battery of
my DJI Phantom.

Further to the novel idea of hacking into a battery's firmware to cause it
to explode: excluding access to the firmware is the solution. That means
the manufacturer would burn the firmware into a ROM chip, which prevents
anyone, even the manufacturer, from upgrading or modifying the firmware.

So, if the manufacturer screws-up the battery firmware to the point of making
the battery dangerous, the manufacturer will have to recall that battery lot and
replace it with a new battery, and new ROM chip-set, with improved firmware.

BOTTOM LINE: excluding firmware upgrades also prevents hacking.

Hi Peter,

    sigh.. this only means your code segment has to be attacked via ram(which is where your code executes from after normally being copied there, ie the stack of a modern von neuman machine is in ram.. and thats where the point of entry is normally for incautious routines nb stack overflows for one, return via lib is another, etc ad nauseam.. again rom is not a security mechnism)), ie if you want your battery to talk to the flight controller or the charging/balancing mechnism.. then you have to allow comms and this is where things start to get dicey security wise for incautious programmers and routines.

    and homeomorphic encryption is just not usable yet..


btw old code from no firmware upgrades INVITES hacking :) (ie no security fixes)

I should have mentioned that I am not a computer programmer...my bad ;-(

Still, there must be a physical way to close all
"back doors” during the
manufacturing process...so the only way to fix a problem is to design and
make a new model...you know, like we use to do before we had computers
Maybe "talking to the flight controller" is a luxury we cannot afford.


There ought to be one-way comm between the smart battery system and
less-smart charger-balancing system. The smart battery system would
determine the capabilities of the
charger-balancing system and then “ALLOW”
or “DIS-ALLOW” the charger-balancing systems actions.
