I don't know if this helps. I started to draw the schematic months ago, and got this down. pEEF did you find a data sheet for the opto devices?
Nice job, pEEF. Mrbirgh, I looked at the BMS system, and decided it was not what I wanted, particularly since souce code is not available. It also...
The ECU monitors both current and voltage. Although monitoring current gives a more accurate estimate of SOC, the voltage monitoring will prevent...

I picked up the battery nearly 2 years ago for $300, thinking that I would add it in parallel with the existing battery. I was planning on buying...
I started to draw the schematic. However, there are some custom parts I couldn't figure out. If it is of interest, I can upload it, but it is very...
I am not sure why you hear a click. However, the Prius does transition automatically from regenerative braking to friction braking when you...
I tried again attaching the file for my battery teardown. This is a work in progress.
Bob: It seems that your wife is sensitive to the refresh rate. ON a PC you can change the rate on the display properties page. Have you tried...
Strange, I uploaded the file, but never saw a link for it. Where do the uploads go?
Very interesting concept. Probably too rich for me, those A123 cells must have cost a pretty $. Very interested to learn how your battery ECU...
I have been reverse engineering the Prius battery pack. I put a collection of things in one document for future retreival. I am in the middle of...
I suspect your ECU got into a funny mode. Try disconnecting the negative battery terminal for a few minutes. That should reset everything. If that...
Mobil 1 is a better oil. It will not cause leaks more then any other oil. When if first came out, the visosity was lower then was used in most...
I wouldn't get all bent out of shape over drum brakes on the rear wheels. ON the Prius, regenerative braking is applied first. Then friction...
DTC No. DTC Detection Condition Trouble Area P0A7F When either condition below is met: • Resistance of HV battery assembly is higher than standard...
Spoofing. I understand that if you monitor the bus, and send a second SOC right after the first, the system will ignore the first, and think the...
I hadn't really thought of that. What I did do was start in EV mode at the bottom of the hill, which is 1/2 mile, steep (7%) grade. With the SOC...
This is the same problem I had 2 weeks ago. I have the Autenginuity, and was able to read the codes. Unfortunately, Autoenginuity does not report...
Seilerts, Seems like charging the traction battery is overkill with a Enginer System. Actually, for just the 1 traction battery, 1 to 2 amps is...
