New energy impregnated hard copper bars: connect rows in parallel between modules to build an efficient and reliable battery system

In the power battery pack, the core of new energy vehicles and energy storage systems, the connection method of battery modules directly determines the performance, safety and life of the system. To achieve higher capacity and more stable current output,Parallel connection between modulesIt is a key technology. We focus on providing high-performanceNew energy immersed plastic hard copper bar, provides excellent solutions for parallel connection between your battery modules to ensure efficient, safe and stable operation of the system.

Why choose impregnated hard copper bars for parallel connection between modules?

In new energy battery systems,Parallel connection between modulesIt can effectively increase battery capacity, improve discharge current capabilities, and enhance system redundancy. adoptedImmersed plastic hard copper barAs a medium connected in parallel, it brings multiple core advantages:

• Excellent insulation protection： dippingThe process forms a uniform, dense and dead-free insulating layer by immersing the entire copper bar in the insulating material. This layer of insulation can effectively isolate high-voltage live parts, completely eliminate the risk of short circuit, and greatly improve system safety. Especially when the spacing between battery modules is tight, its insulation advantages are more prominent. At the same time, it also protects the safety of operators.
• excellent conductivity: Adopt high purityhard copper barAs a conductor, it has extremely low resistivity and excellent electrical conductivity. This ensures minimal energy loss when current is transmitted between modules, reduces the heat generation of the connecting bank itself, thereby improving the charging and discharging efficiency of the entire battery pack.
• High mechanical strength and structural stability: The hard copper bar itself has excellent rigidity and mechanical strength, which can withstand the mechanical stress generated during the installation and operation of the battery module, ensuring long-term stability and reliability of the connection. The immersion layer also provides additional physical protection for the copper bars.
• Environmental corrosion and wear resistance: Impregnated plastic materials usually have excellent acid and alkali resistance, oil pollution resistance, heat resistance, salt spray resistance and other characteristics. This allows the impregnated hard copper bar to maintain stable electrical properties and mechanical integrity and extend its service life in the complex vibration, temperature and chemical environment of electric vehicles.
• Optimize space utilization and increase power density: Because the immersion layer provides reliable insulation, the safety distance between battery modules can be designed to be smaller, thereby achieving a more compact battery pack design and improving the energy density and space utilization of the entire system.
• Easy installation and reduced risk: Pre-insulated impregnated hard copper bars reduce the cumbersome insulation treatment work on site, simplify the assembly process, improve production efficiency, and reduce the risk of insulation damage that may be caused during manual operations.
