I posted this also in another section of the forum

It was recommended that I posted the question here as well. In the other thread the bq34Z100-G1 was suggested as a possible solution.
Here is the original post.
I am planning a 48v battery module that will have capacity options of 22-220ah of energy storage. I also need to monitor currents of at least 1000amps. I have a evaluation board of the BQ76PL455A-Q1 chip and believe this is a good solution for my needs. However I am having problems with coulomb counting and capacity monitoring. My capacity and current rating seems to remove most options for Coulomb/Fuel ICs but searching is proving to be difficult since most products are made for consumer electronics.
I know I can do this manually, but would prefer something that can reduce my workload and is more heavily tested.
Does TI have anything that would match well with the BQ76PL455A-Q1 capability?
When trying to contact an application engineer directly I was pushed to the forums, which is a little frustrating, so I apologize if this is not the best location for this questions.
