In electric vehicles, busbars are mainly used to connect battery systems, motor control systems and other electrical components to ensure efficient transmission of power. Since electric vehicles have extremely high requirements for reliability and safety, the use of busbars not only improves the efficiency of the system, but also enhances the overall stability and safety ‌
The application of busbar in charging pile has many advantages. First, through structural improvement, busbar has strong high-power carrying capacity, improves the running stability, and has short-circuit protection function, which fully enhances the practical performance of the device ‌.

The role of the busbar in the substation is mainly to provide power and signal transmission for various high-voltage equipment to ensure its stability and reliability.
In the field of power transmission and control, busbars can be used in various power transmission and control systems, such as distribution boxes, generators, transformers, relays, power inverters, etc.

The application of the busbar in the bullet train not only improves the efficiency and reliability of the power distribution system, but also ensures the stability of the power supply in the high-speed operation and frequent start/stop process of the bullet train, which is an indispensable key component of the EMU.
