Chargers that can log extensive data about the battery as it charges or discharges

I never had any problems using LogView with the B6 (and various clones), as well as many other chargers. Probably you are suffering from a configuration or hardware issue.

You could try instead DEX = DataExplorer

Gauss,
I did install DataExplorer and it’s a really nice program. Still can’t get any data

I’m curious, you said you had no problem with B6’s and many other chargers…….did all of those connect with a Serial connection because my Authentic B6 mini has a USB port and to connect to DataExplorer I need to configure a HID USB port, but DataExplorer doesn’t seem equipped to do that.

Did you have to use a Serial TTL to USB converter board?

How exactly did you connect all those chargers? If they all simply plugged in and were recognized as serial ports then that would make this exponentially easier. Neither of my chargers are so kind or simple to connect unfortunately because both need to connect via USB

Just found this in Banggood, seems a cheap and good data logging device. Thought it could be of help.

Cheers ^:)

Most of the chargers I used with LogView had usb ports, but on a couple I used TTL to USB adapters (e.g B6 clone) and they worked fine with LogView.

Are you using the latest LogView “Studio” , or the earlier (non-Studio) version? I haven’t tried the Studio version, so it is possible that it may behave differently.

It might be worth trying the earlier version (at least to help narrow down the source of the problem).

According to my old notes, I used this usb driver with tenergy bridge: CP210x USB to UART Bridge VCP Drivers
Silicon Labs

You know what’s interesting? All the YouTube videos and all the posts I could find during all this effort all pointed to this working with older versions of these chargers. I can’t find anything where anyone has had success in the last 4 years or so so maybe all th chips in the chargers have changed and none of the old programs that used to work with the old chargers version work anymore. Just a guess.

Both my chargers come up with C8051F3xx Development Kit - Silicon Labs - MCU as the chipset. I have never seen CP210x. These are both relatively new chargers so maybe all the chipsets have been updated?

I have only tried the latest LogView Studio release. But now that you’ve mentioned it I will download the V2 (the only older version still available) and give it a try. I’m beginning to think I also received a bad USB to TTL adapter board so I ordered several from different sources but some may not arrive until the end of May.

Anyway, it’s been great hearing from you as I’m basically feeling like on somewhere floating in the north Pacific on an iceberg trying to get this to work…very little help around :partying_face:

That looks very interesting and it might be better than what I have.
Thanks for the link. Might get one.

I have this dinosaur in the garage. I haven’t used it in a few years and I’m not sure I still know how.
But it might be able to reveal the information I need.

Yes, the newer chargers are using an HID interface, unlike the older ones, and this is probably the source of the problem. According to this page LogView was working on it a few years ago. I didn’t read the entire thread. Maybe your solution is there.

See also here and here

Not sure how you find all those links but good job! I don’t find those when I do Google search for some reason?

Yes, HID is problem, however, I can get “some” data to go from charger to LogView. But only Hexidecimal.
But the fact that it gets there and I can see it means that the charger is in fact communicating with LogView.
Logview can’t seem to identify and translate the Hexidecimal stream is the problem. Or so it seems.

example……

00 0F 22 55 00 01 02 55 14 1A 2C DB E4 00 2A 00 00 0E F7 0E F8 01 6E 01 43 01 40 00 00 00 00 01 00 D5 FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Hello Zebretta!
I am from Germany and have the same problem with data logging from chargers.

I have two chargers:

1. Graupner Ultramat 18 (12s charger)
   Ultramat 18 Li, Pb,NiMH Ladegerät Graupner 6470 - Hobbydirekt Modellbau e.K.
2. iMax B8 (8s charger)
   https://hobbyking.com/de_de/imax-b8-charger-genuine.html?\_store=de_de

I have tried with the following software with Windows 10, 64 bit:

1. LogView 2.7.6.511
2. LogView Studio 1.0.3662.0903
3. DataExplorer 3.51

I get data from the chargers, but they are not usable for the programs.
I tried about 10 hours with different drivers.
For example:

CP210x USB to UART Bridge VCP Drivers - Silicon Labs

Version 10.1.10

I read some of your threads and one was about to repair the USB-Port of your iMax B6 Mini charger.
So, have you found a solution to log data with LogView, LogView Studio or found something else to log the from your charger?
Best regards
Nils
