Default Battery Communcation Utility Project

Hi,

Here are one of the first results of my project:

Intending to measure cells inside battery pack before to open the casing.

Be back with updates.
Felix.

Yeah, link doesn't work. I think it goes to his account's video edit page.

I have chargers that monitor each battery cell in an electric model but they are only two to six cells. Each cell has its own wires to a separate plug the charger can connect to for monitoring. So, the battery pack has a power plug and a monitor/balancing plug. The dozens of cells in a Segway do not have that kind of wiring so I wonder how they can check individual cells without a voltmeter put on each one (case opened).

I would guess he can't monitor individual cells either - Probably only the 23 groups of 4 cells in parallel

here is new link:
https://youtu.be/-oevROzBgAg

of course not each cell, but 23 groups,
(23 raw values, scaled , but for the moment not offseted, working on it...).
and:
-average temperature
-four temperature sensors,
-state of charge bar graph,
-chemistry and Rev.XX,
-statuses registers, and so on...



Be back with updates!

We have software that does this as well along with many other functions. It looks like your doing a great job so far!

Default Tired of everyone "Making a Mystery" out of the I2C protocol and the battery...

Hey all...

I've been on the sidelines for a few years... but with the rise of the various e-Scooters and NineBot/Segway starting to ramp down the balancing scooter business in favor of the smaller "Mini Segway" the time for closed-source solutions is coming to an end.

Felix, I know that you've put a lot of work into your battery analyzer, and I think it's going to be a great one-stop device for people who want something that "just works!"

The Segway original, i2, x2 market is small, and we need more general purpose and inexpensive tools to let people quickly diagnose their cells, and to let people build compatible cells using Li-Fe batteries ( and if they are so inclined, the more dangerous but more power dense Li-Ion cobalt cells. )

For people who are curious about the I2C protocols and how to communicate with the battery for DIY solutions, or to make projects on the Arduino and with a Raspberry Pi board... I'm going to release an open-source project on GitHub and a set of libraries to talk to the cells along with a BOM and Gerber files sometime in mid to late January.

Since I likewise independently spent the time to reverse engineer the battery I can choose how to proceed with what I've learned. I choose to give it away with an open source license and open source hardware to let others build on that knowledge.

Good luck! See you all in 2019. Code will be uploaded to:

https://www.github.com/martinbogo/i2...ry-diagnostics

Thank you!! And I, for one, canít wait to see the bits. Ready to have some fun with this!

It will be interesting to see what other inventors come up with by using the information that Martin releases.

Also, I am really hoping that Felix is able to bring his ready-to-use device to market soon, because an analyser that can be used in the field will be most useful.

Hi,
The tool was ready to be sold starting from May 2018.
I sold some units, also have on stock, booth versions,
Quick Reader, and the Advanced Capacity Tester that includes forced voltages equalizer, Battery health, and internal resistance measurement.
Now iím learning the Microsoft visual studio to create PC application to
make a nice window to monitor on pc or laptop same data as on tool display,
but more friendly and more display data, also nice graphics and printout
paper as an official data regarding individual tested capacity.
This weekend i will post on youtube the new update of the tool.
Cheers M8ís!
