BQ79616-Q1: Why we need to measure busbar?

Part Number: BQ79616-Q1
Other Parts Discussed in Thread: BQ79616, BQ76952

Team,

In the datasheet of BQ79616, it has a function to measure busbar. May I ask why we need to measure the voltage of busbar? And what is busbar?

Because in other non-stackable AFE, like BQ76952, it has current measurement instead of busbar measurement.

Wish to get your reply, thanks!

    Hi Miles,

    In large HV auto battery systems, they are typically segmented into modules (sets of cells of 4-20 in series). When the pack manufacturers assemble the pack, they need to connect each module together via a "busbar" which is simply a metal connection between modules. It is often desired to be measured to ensure it does not come a loose connection as the car moves over time because losing a bus bar can be a safety critical event. Hence, why we also don't have bus bar measurement for non-stackable devices.

    Regards,

    Taylor
