Battery Management System Busbar

Description

BMS busbar combining power and voltage-sense layers with copper terminal studs.

A BMS busbar combines the high-current path and the voltage-sense layer in one laminated assembly. The paired stud terminals give consistent, low-resistance measurement points across the module, which matters for accurate cell balancing and state-of-charge estimation.

Design Notes

Sense conductor cross-section and stud material are selected for measurement accuracy. Layer separation prevents sense-path interference.
