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...
@Vencedor, I propose creating a new thread with more details to support your claim that "solves all the problems experienced by the Lithium...
Hi!
By whom? Did you watch the whole video? At the end, Pat specifically addresses why he's using his engineering experience to deduce the probable...
While sodium cells can tolerate 0 volts, I'm not aware of anyone shipping them at zero volts commercially. Starting 2026JAN01 30% SoC is the...
I love this narrative that completely disregards the engineering concerns I raise... ...and replaces them with character attacks. You're shooting...
Correct, and I have never made that claim. Not sure what your point is. Not technically true. Here are the three sodium cells I've tested:...
Traction battery cells have huge thermal mass. They cool down every night. If you don't drive during the day, the battery temperature is going...
This guy mudder prefers "providing technical evaluation of poorly designed products..." As of this writing I don't sell a competing product. Not...
I propose the solution is to conformally coat the PCBs, and also to properly space the high voltage traces... ...but glad you got back up and...
Not sure which Team Jack member I'm responding to, but does it even matter? Yes, but we can only use 1/3 of the overall pack capacity with the...
FYI: Here's a color-coded preview of the Gen3's serial protocol: [IMG] ...it's a little more complicated than the Honda Insight's BATTSCI frames,...
I'm designing LiBSU to be battery agnostic. It'll have several serial buses (USB, isoSPI, SPI, UART, CAN, etc), and will support pretty much any...
The circuit board consists entirely of the following circuit, repeated once per cell in series (QTY35 copies per PCB): -a comparator (on the other...
I know it's an old post, but figured I might as well document this here: Gen3 BSU's is an RS485 PHY with 19200 baud DLL with 8 data bits, odd...
Wow, thanks for the heads up. What license is your code under? FYI: I've got the (non-CAN) Gen3 BSU's serial data stream entirely worked out.
To this day, I'm still amazed that NexPower chose a scorched earth policy, rather than acknowledge my (initially private) feedback in a...
Can't wait to review it. Maybe once @jacktheripper finally fixes all the safety issues I pointed out in my previous reviews, he will take down...
