Daily PCB layout update: [ATTACH] Notes: -HVDC section 100% placed. -Connectors 100% placed. -Should have all remaining parts placed tomorrow....
It's crazy that TE makes "wire-to-board" connector housings (1473143-1) that they don't also sell mating headers for. In other words, a company...
I'm confident everything fits: [ATTACH] Disregard the missing HVDC creepage and clearance; this is a rough layout for now. I swapped several...
So eventually everything needs to fit inside the yellow border... [ATTACH] I think everything will fit, even though I'm using relatively large...
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...
I agree: LiControl wasn't amenable to the massive feature creep our loving Insight community thrust upon it ;). LiControl was never intended to...
"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...
Pegged! [ATTACH] Almost done with the schematic... starting my weekend now, but I'll be back at it when I get back. So far I've reduced the BOM...
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...
