Separate names with a comma.
That is exactly the $64,000 question (or use whatever value you put on your Prius). There's a lot of existing content on PriusChat about that;...
[MEDIA] I come across lots of videos on Lithium Ion as direct replacement for NiMH batteries on Prii. Lots of local workshops in my country...
Excellent questions! I've replied inline. LiBSU has an I2C port, which I will use for my own debug purposes with the same 4x20 LCD that I use in...
"HVDCDC" means the isolated switch mode power supply that converts the HVDC pack voltage (e.g. 240 Vdc) to a local 12 volt rail, which then powers...
Thanks. It's taken a while for me to get to this project, but now it's full steam ahead. Spent the day penciling in LiBSU's blank hardware...
I agree with the limitations of NCM chemistry; perhaps with 5S, things would be better. The fact that the cells operate at a low voltage can be...
Hi @Vencedor, Really nice thread — great to see a constructive discussion here at my favorite corner of PriusChat! We actually experimented with...
First of all, I'm 100% sure that your LiBSU product will be the solution we need. I've seen the work you've done with Honda, and it's the product...
That's my primary concern with your proposed off the shelf BMS solution. Note that my LiBSU controller will cost less than said BMS solution......
I agree that it's slightly outside the range that would be appropriate for lithium. In my tests, 90% of the time the car stays between 45% (15V)...
I always appreciate people sharing information, so thanks. The 'happy path' range I've seen spans from 12.9 volts to 17.9 volts, which is close...
It's a standard programmable MOSFET-switched BMS, with protections that you have to configure. The car will always try to use the battery at...
Thanks for clarifying your research... I need more time to process this info above tomorrow... But for starters, why have Honda mods been so...
Without communicating with the car, how do you intend to tell the OEM Toyota computer to stop charging/discharging a too full/empty pack? Relying...
There is a Prius battery rebuild company near me that claims they warehouse a bunch of modules. Deep cycle(s) them, characterizes them and combine...
Okay, well he spend a lot of time and money on that project. I remember from the 60's with old D cell batteries they would say don't mixed use...
haha wasn't my work. Just found the video of this guy's work. Certainly a newer battery would have been preferably for longevity. I think old...
This is a false equivalency. NiMH's end of charge behavior is drastically different from lithium. Specifically, NiMH cells can 'perpetually'...
...advantageous because it helps heat up the cells faster. Some lithium BMS systems will run a current limited AC signal into lithium batteries...
I have copied and pasted the posts from the other thread into this thread so that everything is together.
