Re: [PSES] CAN/CSA C22.2 No. 62133-2:20 for CR 2032 Batteries?

Mon, 22 Jul 2024 11:01:20 -0700

OOPS! I missed that about 'rechargeable'. CR2032 cells are not normally rechargeable, so the standard doesn't apply.

I don't know the meaning of the final '20' in the reference to the 
standard; it may be that it should be a date, like 2021. There appears 
to be nothing in the underlying IEC 62133-2: 2017 + AMD1:2021 that 
would exclude any coin cell.

Hello all,


We’ve been seeing Amazon requiring CAN/CSA C22.2 No. 62133-2:20 for 
all products that use or contain at time of sale a CR 2032 coin cell 
battery. I was of the understanding that this standard did not apply 
to this battery. Unfortunately, I do not possess a copy of the 
standard so I cannot verify this myself. MayI ask if anyone here can 
offer verification or rebuttal please?


Best regards,

John

So I just finished reading "1.2 kV/400 A SiC Source Turn-Off MOSFET 
Intelligent Power Module" 
(https://ieeexplore.ieee.org/document/10574416 
<https://urldefense.proofpoint.com/v2/url?u=https-3A__ieeexplore.ieee.org_document_10574416&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=x40qV4DM3u4JrqHl_FVpxdOqkHDBo3f6BvwvAwIWGH8&m=a2CCo_J4V1NasdwIBe0EeqpUJTYCY_V6Tmg345FDzau0JquoopInoKrPLEhikCaN&s=_UxHI-pyQoHSCbqUQCVFvIEGK_7RUdJisvq72DPJL8w&e=>)



The word "intelligent" in the title of the article piqued my 
interest.  So, what's with the overuse of the term "intelligent" 
nowadays?  When I read the article, I noticed that the word appeared 
only three times: once in the title, once in the abstract, and once 
in the opening paragraph. The acronym "IPM" appeared 31 times 
throughout.  I saw no mention of any aspects of operational 
intelligence used in the design of this power module.  Is there 
something I missed, or is the term "Intelligence" being used as 
marketing hype?



I'm seriously experiencing some fatigue over all this talk of 
Intelligence, Machine Intelligence, and Artificial Intelligence.


Thanks for letting me air out a little,  ~Doug
