[PROJECT] Lithium battery for Prius

How did your battery project end up?

 

Which cells are you using? Are those from a gen 4 lithium non Prime? I have a bunch of gen 1 Pip-PHV-Plug In Prius cells and plan to start working on better understanding the BMS and reading, processing and outputting the data of a 14S Brick for starters and using with a portable power station OUPES Mega 1 for now. Then appears like you are doing where using the gen 2 HV pack parts other than the NiMH modules and frame harnesses. Thinking that will be easier to code, i.e. translating the 4 NMC cells to look like a gen 2/3/4 block. Then, would be awesome to get to the time to be able to custom make the HV battery sense computer, ideally ultimately for the gen 1 Pip to provide more options in the future and rescue those.

 

Did you create a Youtube, github or some sort of repo online anywhere with your design(s)? Please share if you did, albeit I still need to read through all the Linsight related files.

The Linsight LiBCM LiBSU seems to be able to utilize 60S max from what I recall reading, though no one has modified from what I've read so far for over the 42S or 48S maybe Ford pack if I am remembering correctly. Guessing might save some time and at the least inspire if I go another direction as would be nice to add an EV mode functionality and seemed like one other CAN bus controls functionality like a EV mode acceleration from a complete stop always to improve MPG's. PriUPS functionality would be great as well, so mobile medic not only for Priuses.

Reads like I assumed right, your design uses the factory Prius HV battery parts and only feeds the contactors for power and HV battery sense computer sense wire connection for block electrical data?

Amazing what is on the market now a days, albeit with size constraints in regards to cells capable of some serious capacity. Like if say 201V and using the 314aH LiFePO4 cells, that's crazy huge like ~63KWh guessing if grade A cells. Nuts! I haven't found what the latest high capacity NMC or whatever Lithium Ion/Polymer battery is as of late and cost effective. Seems all my reading migrates me to LiFePO4, though I need to stay focused on the cells we now have and to put to good use.

I just picked up my last order of parts, I think at least, that I need to start working on the 14S external pack first phase. I'm going to really badly try to document on Youtube at the least, though I am so far behind on editing and other needs that I've only been posting unedited videos lately to keep me reminded of chores.

Hopefully I can motivate you, as I know the powers at be seem to keep us down and waste some perfectly good enough objects. Seems good if not great to me and better than fantastical tangents from reality foolishness. Vehicles, especially reliable ones, can get people to work, school, chores and even survive in as lodging.

$700 definitely is a good buy in the right environment (avg climate temps come to mind), so hope I can inspire you to keep on keeping on as I plan somewhat similar in the next phase after I better understand my over priced ESP32 thoughts direction regarding phase 1 design with the Daly and JBD BMS's with hardwired and the wireless displays for metrics with potential CAN bus transmissions, though more likely I'll get into the CAN bus transmissions in phase 2.
