New microcontroller bord, also new bigger TFT Display 480x320

Pretty close to be listed on ebay.de
Need to find a discharge load.
Also to choose a good housing.
After some experince in .de will try worldwide.

Revive from deep discharge function tested and works, live data during revive!
mAh intergration during charge and discharge to retrive real capacity of battery.
Internal impedance and eqivalent dynamic serial resistance measurement with.
derivative echo of dv/di during instant discharge.
Fleet owners will have the posibility to sort batteryes to decide what to sell and what to keep
when sell older units!
Tool eqipped with 3xIFR18650-22P to use as a stand allone tool, good to use anywhre,
even in open field, just connect to battery plug and read voltages and others instantly.

Soon!

Exellent Work!

Hello,
I have verry good news for ones that revive AF to AJ packs,
Will offer tools in different ways on demand:
-just a simple passive monitor that displays 23 cells voltages and 4 tempratures
without ADC real pinout voltage. 500€.
-same as before but with ADC pinout measuring pinout voltage and courent discharge probe, fused, you may visualise the weak cell(s).
-tool with all protections imagined to full integration of coutent wille charge/discharge to calculate real internal static resistance and impdance of batt, also close to real mAh capaity of battery package.
-more registers values from BMS.


Communication protocols that I suppopt and can explain, are for sale now!

Great work Felix.

I wish you all the very best of luck

This will be a really useful Utility for many people
 

Hi Felix

Your Battery Communications Utility looks like it is developing really well. This will be a really useful Utility for many people. The ability to determine the Battery Pack Resistance in the field will be helpful in determining whether a pack might be the cause of certain Safety Shutdowns and/or should be replaced because it is approaching end-of-life. Even more useful for businesses will be the ability to determine the full-charge capacity of an older pack.

All the best with getting your Utility completed.

Hi
I'm working on housing solution. Till then will finish some other needed functions.
One by one will to them all.

Today have finish with the four temperature sensors,
(needed for reviving from deep discharge function), see photos.

Next will be the charge/discharge 100Hz PWM switches.
I found interesting discharge load also.
Be back with updates!

Great stuff!

I like to know if the battery communication is with an I2C or SMBUS.
Is it 5v tolerant or only a 3.3V level ?
Where are the SDA and SCL on the 2 pins (side near the ground power pin).

Hello Mates,

I'm back from a busy period regarding automotive business. Will keep on going with the tool.
The problem is that I cannot find good prototyping housings.
Searching for a handheld box with batteries, also display window. I found something but not as expected.

cheers!
