Power batteries are the core of electric vehicles, and the power of vehicle batteries is relatively high. Power batteries are a combination of battery modules connected in series or in parallel, and each battery cell requires a conductive material that can both conduct electricity and provide insulation. Traditional insulated cables are no longer suitable. After market recognition, a type of electrical conductor and ground layer material separated by an insulator - busbar - has been proven to be an ideal conductive component.
During the driving process of a car, vibration is constantly generated, especially when the battery is misaligned during operation. Traditional battery connections are prone to malfunctions, causing significant safety hazards. This is why it is necessary to introduce bus bars as a power battery interconnection solution to overcome these challenges.
Busbars are usually made of copper or aluminum, with a flat and rigid structure. Compared to traditional cables with the same cross-sectional area, they can carry more current, support 15% more power than cables, and have a larger surface area, making it easier to dissipate heat than cables. Currently, battery manufacturers are pursuing increasing the power of electric vehicle batteries to reduce vehicle charging time, which is also why busbars have become an ideal choice for electric vehicle power batteries and an important component of future vehicle electrical architecture.
The busbar structure is flat, making it a good carrier for large current transmission. It is more curved and compact than traditional cables, making it easier to form precise angles, which is conducive to tightly fitting the car itself and making room for other electrical components.
