The use of copper flexible connectors (also known as flexible copper bars or copper braided tapes) in energy storage cabinets is mainly based on the following key reasons:
1. Excellent conductivity and low resistance
-Copper has a conductivity second only to silver, which enables efficient transmission of large currents and reduces energy loss.
-The flat braided structure with soft connectors increases the surface area of the conductor, further reducing resistance and heat generation, making it suitable for high current requirements of energy storage systems.
2. Coping with vibration and displacement
-The batteries in the energy storage cabinet may experience slight displacement during charging and discharging due to thermal expansion, contraction, or mechanical vibration.
-The flexibility of copper flexible connections can absorb vibration and displacement stress, avoiding fracture or loosening of rigid connections (such as copper bars) caused by repeated stress, and improving reliability.
3. Advantages of thermal management
-When working with high current, it is easy to generate heat. Copper's high thermal conductivity can quickly dissipate heat and reduce the formation of hot spots.
-Flexible design allows for free expansion and contraction during thermal expansion and contraction, preventing the accumulation of thermal stress.
4. Installation flexibility and space saving
-Soft connections can bend and adapt to complex layouts, especially in compact energy storage cabinets, which can bypass obstacles and simplify installation.
-Compared to rigid connections, it is easier to adjust and maintain.
5. Corrosion resistance and long lifespan
-Copper surfaces can be plated with tin or nickel to enhance oxidation and corrosion resistance, and adapt to humid or harsh environments.
-Flexible structures have strong fatigue resistance and are not easily aged after long-term use.
6. Safety and Electromagnetic Compatibility
-Low resistance reduces the risk of overheating and lowers the risk of fire hazards.
-Good electromagnetic shielding performance reduces interference and ensures signal stability of energy storage systems.
