Hot Plug BMS when building a pack?

Hi

Was looking deeper into bq76PL455A-Q1 for a BMS and I noticed there is a ton of passives needed for protection against hot plugging.

Here on ES, I searched and did not see much discussion specific to the initial attachment of the BMS to the newly built battery stack. I figure this is a dangerous time, even if everything is built and wired correctly. The inrush current could be huge.

I assume some BMS would prefer the battery to connect first, then the balance leads. For others this may be vice versa. Does anyone know of any specific recommendations?

Thanks

John

The correct connection sequence really depends on the model of BMS chipset used.
Some years ago I've worked with the Texas bq78pl116 and its bq76PL102 slave extender that require a very specific connection sequence.
I've damaged a few chips before to discover this document:

This chip is particularly picky because it has PowerPump Cell Balancing and cell impedance measurement that require a low impedance path to the chip.

Others simpler BMS circuits can be made more robust because they can be protected with quite high resistance between cells and chip connection.

There's a few threads in this list that are relevant (most aren't), you can judge by title.
