Separate names with a comma.
Are you referring to NexPower V1, V2, V2.5, V3, or V3GT, or whatever new version they're announcing next month? Just wondering. Please reread my...
Sounds like you understand the development process. Yes, your question is premature, but we will need to figure it all out eventually. For now,...
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...
Great questions! The Honda Insight LiBCM project is already open source. The Toyota LiBSU project will have both open source and closed source...
Here's all the data the Gen3 Prius' OEM BSU sends the main hybrid computer: -QTY14 blade Voltages, and; -QTY3 battery temps, and; -QTY1 intake...
Just finished the LiBSU proof of concept: [MEDIA] This project is finally in full swing! Excited to start the RevA schematic tomorrow!
With 5S/blade, you're looking at a per-cell operating range between: ~2.5 volts (under 0% SoC) on the low end, and; ~3.5 volts (15% SoC) on the...
Thanks for taking the time to provide this background information, Jack. LiBSU can prevent the EOL scenario you described from ever occurring....
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......
How does your BMS tell the car to stop charging in this example? How does your BMS tell the car to discharge in this example? As @ChapmanF...
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...
The Gen3 Prius I just bought has/had a functional NiMH battery, too... yoinked it out day one to make space for this project. You now have the #1...
Are you intending to place an inline power MOSFET in series with the pack positive? If so, any out-of-bounds excursion will disconnect the...
Take your time... I'll be here. I haven't spent enough time in both camps to fully understand the Toyota mindset... ...but if members on other...
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...
If you outline your BMS strategy before designing it, I'll let you know if your plan is unsafe. Unfortunately, I'd need to look at the finished...
@Vencedor, any thoughts/response to the concerns I outlined on Friday? Maybe you don't work weekends?
This is a false equivalency. NiMH's end of charge behavior is drastically different from lithium. Specifically, NiMH cells can 'perpetually'...
A more correct statement: Charging a frozen lithium battery too quickly can cause permanent damage. When the normally liquid solvent between the...
No balancing at all with lithium ion cells is a disaster waiting to happen. Not measuring intermediate cell voltages is scary, too. I agree, but...
