Separate names with a comma.
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...
@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...
