a busbar might experience thermal expansion.For the busbar, the results of the simulations lead to optimizations of the cross-section, the amount of copper or aluminum used and the design of the terminal connections — all of which will help ensure that OEMs have a product design that meets their requireme
ptimizing Busbars for Advanced ApplicationsOn the surface, busbars appear to be simple — they are just rigid metal bars, after all, albeit ones that can support the high power required for today’s electric vehicles (EVs), both inside the battery pack and, increasingly, outside the ba
Busbars and interconnects will also be affected by architectural developments such as the adoption of cell-to-pack (CTP) and cell-to-chassis (CTC) battery configurations. CTP and CTC batteries are often structural, and tend to require much larger current collectors, but the basic architecture is generally the same regardless of size.
.PRODUCT DESIGN CHOICESConductor selectionBusbars are ideal for the high-po er applications that are commonplace in EVs. OEMs first started using busbars in EV batter packs as interconnects for battery modules. To support fast charging, busbars have
While the cell form factor used in a battery does not affect busbar and interconnect designs in any fundamental way, battery architectures and cell connection systems have had to adapt to cylindrical, prismatic and pouch cells, and the placement of terminals is important, he points out.
With busbars, one of the most important considerations is electrical insulation, which is critical to the integrity of the whole electrical system, both in normal operations and in mitigating the effects of thermal runaway, for example, according to an engineer from a major chemicals company.
