Separate names with a comma.
$1000 is quite expensive for this. The dealers around here charge $750-$800 to replace a failed CM (parts and labor), and an independent shop will...
I'm pretty certain this is correct. That was also the speculation in the (now very old) tear-down analysis from EE Times:...
I also use the Reaktor and have the same frustration with using the capacity limiting. Effectively, the Reaktor treats reaching the capacity limit...
Probably moisture. There is no dielectric grease in the connector, as you would typically find in a connector under the hood, to protect against...
This looks very similar to the problem I had with the first pack I worked on. I also could not disconnect the orange sense plug from the ECU with...
Did you take your no-load (open circuit) voltage measurements before or after the discharge caused by the loading? There are advantages to using...
Hello BJ, did you resolve your combination meter problem (presumably without Toyota help)? I now have this problem on an '04 which is...
Wow, that capacity increased nicely. I understand your concern about the self-discharge (18% over 10 days by my arithmetic). I don't have...
Sounds like good progress. I hope the added cycles have the desired outcome. Go module 12! -Marc
On second thought, I don't want to kill modules with 5800-5900 mAHr. I agree there are likely folks out there who would like to use them in a...
As bad modules go, yours look pretty good! I agree with SEaton that you should give them a few more cycles. The fact that you are hitting your...
Saw in another thread that you stated you were having problems with your balancing. How about an update ...
It's been a while since I have provided any update. I have not finished the project yet but am making steady progress. On the voltage sense...
Did you start with the discharge? What makes you think it is overcharging? Note that you will need to charge beyond the rated capacity of the...
Thanks for the schematic ... pretty simple. You are correct that those devices are typically 1.5A max current in the TO220 package. Good luck...
That is more elegant (soldering job notwithstanding) than what I was considering. I was considering simple power resistors with, effectively, a...
"Charging/discharging is not a balancing. They are tested with 3 times charging/discharging and this help the capacity to be increased." Thanks...
Good point regarding doing these things in parallel ... you almost cut the time in half. If you do decide to do this piecemeal, note that you...
Yes, those are the correct battery capacities. The batteries can safely be discharged at a much higher rate. With the monitoring software on a...
SEaton, it is better to overthink than underthink ... especially in this context! I was thinking through the same purchase decision a couple of...
