Other Parts Discussed in Thread: BQ79616-Q1
Hi.
1. It says in another TI support "The EM1401EVM did not allow balancing between modules and the alternative was to balance higher modules down using additional dissipative methods or running the high module active circuit to cause dissipation." How can this problem be eliminated and not use an isolated 12V pack, on a 600V power pack? In other words, I am trying to design a 600V battery pack that keeps every cell at the same voltage, uses active balancing and does not require a secondary, external power source. Any suggestions?
2. We would like to modify the EV1402EVM so it does energy transfer from a cell to the module (battery pack), or from the module (battery pack) to a cell, similar to what the EM1401EVM used to do instead of from cell to isolated 12V pack. How can this be done? Do you have any application notes we can use to get started?
3. Is it still possible to purchase an EM1401EVM? Any plans on updating the EM1402EVM to do cell to/from pack active balancing and eliminating the isolated 12V?
4. Any application notes on how to do active balancing with the bq79616-Q1?
Thank you for your support.
