The Importance of Busbars in Battery Packs Busbars are thick strips of conductive material, usually copper or aluminum, that are used to distribute power within the battery pack. They play a pivotal role in connecting individual cells or modules, conducting high currents, and ensuring minimal power loss across connections.
This integration offers several key advantages, such as: 1. Streamlined Design: Integrated busbars reduce the complexity of the battery architecture by minimizing the number of connections and components, which can lead to a lighter and more cost-effective solution.
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.
In the case of cylindrical cells it is possible to connect to both the positive and negative terminals of the cell on the top surface. The result is a simplified busbar that gets repeated through the module/pack. Thus leaving the bottom of the cell free for cooling. Cell Busbar Thermal Model Can we build a quite simple cell busbar thermal model?
This is where the Combined Charging System (CCS) integrated busbar solution comes into play, offering a streamlined approach to energy management in electric vehicle (EV) battery packs. Introduction to New Energy Vehicle Battery Packs
They play a pivotal role in connecting individual cells or modules, conducting high currents, and ensuring minimal power loss across connections. With the scaling-up of battery capacities and the need for faster charging times, the efficiency and design of busbars have become increasingly important.
