First I'll ask your forgiveness for posting without first reading the entire thread! I'm a little over worked at this moment, but I would really like to have a bit of input on this. I'm slowly working on a LiFePO₄ adjunct battery system (for the trunk or such) that works in parallel with the...

Well, that's what I'm going to examine. I'm researching various circuits and I'll probably set up a SPICE simulation to see how it does.

Hello mux! Thank you for sharing your experience! My concept is slightly different however, though I won't say it's the best idea. My plan is to put a current-limiting, boost power supply between the adjunct battery and the LBC-PDM junction so that I have precise control over both current and...

Thank you Lothsahn! It's good to know that somebody is already doing this! Even if it's a proprietary, commercial enterprise. I would really like to see a solution out there in the FOSS / open hardware space and would prefer to use LiFePO₄. Thanks for the lead on CATL. This is the first time...

This is my personal thought, but I'll have to play with it to verify that the issue is sabatoge when it sees the battery going down instead of up. As you're probably aware, when you plug in the J1772 L1 or L2 charger, the charging hardware in the PDM takes responsibility for doing the charging...

There are many companies who will cap decap ICs for you, so this isn't unreasonable (e.g., 1, 2, 3). It can be costly and, iiuc, it may take a few attempts to get 100% of the firmware area visibly readable (from a microscope). As far as compiled C code and/or assembly, it is BY NO MEANS...

My 2013 Leaf is down to 8 bars and I'll surely loose another come summer. Having recently sold my house, I finally have the money to either replace/upgrade batteries or buy a new car. I'm excited about the prospect of a 40kWh LiFePO₄ battery pack from EVs Enhanced, but it's not ready yet. Since...

Finally, this investigation is actually leading me to believe that hehe, I failed to notice the second page of responses on this post. :D This tells me precisely what I was suspecting -- that there's very likely nothing wrong with the CAN communications from CHAdeMO to PMU, it's just that the...

BTW, I can think of another solution that so pretty because it involves modifying the vehicle, but should work. Hijack the connection between the LBC and the rest of the car (á la Dala [pun intended]) so you can omit/manipulate any information we necessary to keep it from freaking out, and...

Sorry for disappearing for a bit. I just closed on selling my house, thus completing my divorce (FREEDOM!) and simultaneously having life jump me. Things are gradually settling down here. Here in the states, we have the worst laws when it comes to protecting the rights of the consumer. There...

Nearly impossible to argue with! Further, this could be a handy product -- makes me wonder if anybody's already making one. I guess the main thing is that you set a min battery level so you don't get yourself stranded. I used to work construction and pretty much nothing happened until we got...

Well that's not really the question, is it? Not that I mean to be rude. None the less, I'm feeling like your idea has a lot of value as it could be reusable on many different cars and wouldn't require modifications to the vehicle. It would need settings so the user can dictate a maximum...

Thank you. I've read a tiny bit about this and I understand that it's a two-way street. But this would also mean that it could only be used while the car is parked. I also recall that CHademo means that you are the charging controller, and I presume this means you become responsible for...

Wow! What a wealth of helpful information. THANK YOU! So you just stuck a 120Ω dummy load and drained it right down. I'm presuming that the car was off during this? Otherwise, I would really hope that VCM would tell the LBC to shut off power, since a current leak could mean very bad things. As...

Hello! I am intellectually gifted person, but it all seems to have come out of the "sanity" stat when my character was rolled. (Thankfully, I'm at least aware that I don't always know what's good for me!) None the less, I have a 2013 Leaf and would rather like to add: a 2.4kW-ish DC/AC...
