I'm asking out of curiosity. After the March update of the Dr. Prius app, it stopped connecting to my NHW11. Do you happen to have a similar problem? I've tried both the cheap Vbox OBD2 reader and the more expensive Veepeak, and the same problem persists.
Yeah, you have to download an older version of the app. I did not dive too deeply but I simply uninstalled the latest version, googled "dr prius apk", and downloaded whichever CNET had available since its a trustworthy source, at least it was growing up lol
I've never gotten Dr. Prius to work with my G1s. I assumed it didn't because of our old com protocol. All it does is show the demo app and, I forget exactly, but it showed some rudimentary data, but nothing useful for understanding battery health. Am I doing something wrong? What data does it provide for y'all.
Thanks. In fact, after installing the older version it started working. In my case ver. 6.59 Dr. Prius won't show anything beyond basic data for the NHW11. You can only partially verify the battery yourself by measuring the Delta SOC and Volt diff parameters, as well as the internal cell resistance.
Since were on the subject, my 2002 Prius has a five year old remanufactured battery from Greentec Auto that's now making the car limp. I reckon that if I'm going to take the hybrid battery out myself anyway before getting another one that I perhaps try and repair it myself before coughing up another $1400-2000 for another replacement. Do you guys see any correlation between the fault codes and these readings?
My battery has a lower delta SOC and higher cell resistance, and it's not throwing any errors. In my opinion, the second battery simply has a problem with corrosion in the bus bars. Simply cleaning the connections should fix it without the need to replace anything. The photo shows corrosion on my battery right after purchasing Prius.
Your third picture, in particular, shows large voltage spikes in the "volt diff." I've seen similar problems in a Prius Gen2 and a Lexus CT caused by corrosion.
