Technical FAQs 4

What is a battery bus bar?

A battery bus bar is a solid and conducting material applied in connecting batteries, battery packs, or cells in a manner that allows a steady current. The most common sites where you can find it are in solar energy systems, electric cars, or arrays of big batteries.

What is a busbar used for?

In battery packs for electric mobility, a busbar is used to connect battery cells or modules. In automotive battery packs, busbars are used to connect battery modules together. Busbars are made of copper. In a schematic, a very small resistance represents the busbar. Busbars typically have very low impedance. Figure 1. Busbar example

How to optimize busbars for battery packs?

Optimizing busbars for battery packs requires balancing electrical, thermal, and mechanical performance. Unlike simple conductors, modern busbars must handle pulsed currents up to 10x their rated capacity while surviving vibration, thermal expansion, and decades of operation. Let’s dissect the four pillars of effective design:

How many electric vehicle battery busbars are there?

The red circles show data from 5 electric vehicle battery busbars. The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2. The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size.
