Love this initiative.
Sorry in advance if the formatting of this is annoying. Unstructured as read...
Feedback on current live version:
•good intro establishing motivation and "method" (knowledge accumulates, scattered across random threads, many threads have at least one "slightly off topic" gem in addition to an on topic one.
•maybe specify voltage requirement for lab power supply
•good overview of chemistry
•maybe emphasize the necessity or rationale of setting voltage before connecting cell(s) (some metaphor about cruise control popped into my head, idunno.)
•while not having over temperature disconnect, under temperature disconnect, can be relatively safe in my view with LiFePO4 but in my view those ought to be listed together with OVD and UVD. the longevity of the user's battery pack, which might have been bought on money with no replacement money available, OTD+UTD would prevent loss of service. in my opinion, long term dendrite failure mode can be considered a catastrophic failure that the BMS can protect against
(charging/discharging during certain cell material being at certain temperatures)
•love the recommendation for flexible bus bars. thinking about the 3D g-force time signal being applied to the terminals and the jelly roll makes me want to find a press to smash some copper onto some braided ground patch conductor or whatever.
•re:busbar maybe add distinguishing bit that flexible bus bar is called for in mobile application especially with motion, but stationary application, in some cases the cell is not flexing over SOC curve (mobile/stationary : flex/solid : breathingcell/nonbreathingcell)
•fixure: perhaps distinguish between "breathing cells" and "non breathing cells" e.g. those which geometrically deform due to the changing internal pressure inside the aluminum cell shell's volume. maybe emphasize the nature of electrical insulation (thermal insulation may be needed in an orthogonal manner to electrical insulation in some cases)
•disconnect: maybe list a few types of appropriate types of disconnects e.g. solenoid spring mechanical contact type, mosfet, maybe a tiny comment about derating and local temperature.
•cables: maybe clarify specific type of conductor desired. in my case the type of conductor desired is stranded bare copper or stranded tinned copper. maybe emphasize fineness of conductor as a factor in being able to "make the bend"
•maybe add small mention of a few different types of acceptable cable insulation. Silicone is one that I like a lot, but it's kind of easy to nick.
hope this is in some way helpful and if any part comes across as upset about the quality of the article, not to worry, it's great. this whole place is great.
