Energy storage systems often involve multiple types of energy, equipment, and substances, and are complex energy systems that change over time. Energy storage systems are mainly used to overcome the temporal and local differences between energy supply and demand. The energy storage battery pack is an important component of the energy storage system, and stable and reliable conductive connections are required between the energy storage batteries. Nowadays, the most common conductive connection component is powder coated hard copper busbars.
Powder coated hard copper busbars are treated with cured epoxy insulation resin for spray molding, which has good acid alkali resistance and melting resistance. Powder coated copper busbars are beneficial for improving chemical stability and thus increasing the service life of hard copper busbars. The surface of hard copper busbars is coated with epoxy resin, which has good conductivity. New energy hard copper busbars are used between new energy storage systems and are one of the good solutions for conducting series connections between energy storage battery modules.
Powder coated hard copper busbars are usually coated with epoxy insulation resin powder, which is mainly used to solidify the resin powder and reduce shrinkage, resulting in less internal stress and improving the adhesion of the hard copper busbars. The cured epoxy insulation resin powder has high dielectric properties and can effectively reduce the leakage and arc on the surface of hard copper busbars, making it an excellent insulation material.
The epoxy resin coating on the surface of the copper busbar adopts a spraying process, which is not affected by the specifications and shape of the copper busbar. Even at the bending point of the busbar, there will be no wrinkles, bubbles, and other small holes, and it has good pressure resistance. The hard copper busbar designed in this way combines the stiffness and hardness of the original copper busbar, and also has advantages such as corrosion resistance and wear resistance. It is a conductive connection solution between high current products, and is therefore widely used for the connection between new energy storage systems.
