I am trying to choose a suitable SBS 1.1 compliant design for a 4S2P or 4S3P Li-Ion pack. I have googled but been unable to find very many ready-made packs that would suit my needs. I am therefore considering developing my own PCB as a first step.
I have looked at bq20z45 / bq20z65 / bq20z75 / bq20z95 but I have a problem understanding how they relate to each other. I won't need LED or LCD monitoring, so I guess that leaves me with bq20z45 and bq20z75? Which one should I choose with regards to features, price, and market share?
Thanks in advance.
The bq20z45 would be the best choice as it is the latest solution with the most accurate Impedance Track gas gauge updates and the latest feature updates regarding charge control and protection/safety.
I have some additional questions that are a bit off-topic, if that's ok:
Which practical and legal concerns are there regarding Li-Ion battery packs? Do I need to certify the finished battery pack with regards to selling or transportation?
I'm not an expert in the area of certifications but I am sure there will some level of transportation certification requirements due to the Lithium content and then there are potentially end equipment certifications needed. These will all depend on the region of origin and end use etc... Sorry I could not be much help on this one.
Thanks nonetheless. I have another question that you might not be allowed to comment on, but I'll give it a try:
I have googled for suppliers of complete Li-Ion battery packs with SBS 1.1 support, but I mostly come up with either cheap noname cells or simple or weak PCM modules. Could somebody please recommend a supplier, preferably in Europe? If public recommendations are against forum policy, please send it as a private message instead.
I'll contact you by email in a few minutes.
