If you go to the EVM page (under "Tools & Software" tab) and look at the following link:

http://www.ti.com/tool/bq76930evm

You will see at the end of the document there is a schematic of the EVM that shows how to implement it.

Thanks for the very fast reply.

Also thanks for pointing the schematics out to me. Just one little question, what do the red crosses mean?

It mean DNP (Do Not Populate). This PCB was also used for the 76940 EVM which is setup for 15 cells. We simply have two load option, one for the 76930 and one for the 76940.
