As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing high-performance Custom Tinned Copper Busbar Conductors tailored for Electric Vehicle (EV) battery pack applications. Our busbars are engineered to provide reliable, efficient, and durable electrical connections, a critical component in the evolving EV industry. We combine rigorous manufacturing processes with comprehensive material verification, ensuring each product meets stringent specifications for conductivity, mechanical strength, and longevity.
The core value of our custom busbars lies in their ability to optimize electrical performance within battery modules. By using pure copper as the base material and applying a protective tin plating, we enhance corrosion resistance and maintain excellent electrical conductivity over the product's lifecycle. Furthermore, every batch of material used in production is accompanied by a Mill Test Report (MTR), providing transparent, traceable data on the copper's chemical composition and physical properties. This commitment to quality and documentation supports our clients in building safer, more efficient, and compliant EV battery systems.
Our manufacturing expertise allows us to offer fully customizable solutions. We understand that each EV battery pack design has unique requirements for busbar dimensions, shapes, and connection points.
- Material Excellence: We utilize high-grade pure copper, known for its superior electrical conductivity, as the core material. The application of a uniform tin plating layer protects the copper from oxidation and corrosion, especially in the varied environmental conditions faced by EVs.
- Precision Customization: Busbars are manufactured to your exact specifications. This includes precise length, width, thickness, complex bending or shaping, and the drilling of specific hole patterns for bolt or weld connections.
- Quality Assurance & Traceability: The included Mill Test Report is a cornerstone of our quality process. It verifies the material's pedigree, detailing properties such as tensile strength, elongation, and chemical analysis, giving you confidence in the raw material quality.
- Technical Performance: Our busbars are designed to minimize electrical resistance, reduce thermal buildup, and ensure stable current distribution across battery cells, contributing to overall pack efficiency and safety.
- Scalable Production: Supported by our structured manufacturing setup with 11-50 employees and an annual export value demonstrating significant capacity, we are equipped to handle both prototype batches and large-volume orders efficiently.

Frequently Asked Questions (FAQ)
Q1: What is the primary benefit of tin plating on the copper busbar?
A: Tin plating provides a protective layer that prevents the underlying copper from oxidizing and corroding. This maintains the busbar's high electrical conductivity over its lifetime and ensures reliable performance in the often humid or variable environments inside an EV battery pack.
Q2: Can you produce busbars with very specific, non-standard shapes or complex bends?
A: Yes, our manufacturing process is geared towards full customization. We can produce busbars with intricate shapes, multiple bends, and specific profiles based on your provided technical drawings or specifications.
Q3: What exactly is included in the Mill Test Report (MTR), and why is it important?
A: The MTR is a certificate from the copper mill that details the chemical composition and mechanical properties (like tensile strength, yield strength, elongation) of the raw material batch. It is crucial for traceability, quality verification, and often required for compliance in high-reliability applications like EV batteries.
Q4: What are the typical thickness and width ranges you can manufacture?
A: We commonly work within thicknesses from 1.0 mm to 10.0 mm and widths from 10 mm to 200 mm. These ranges can often be extended based on specific project needs and our equipment capabilities.
Q5: Do you offer different plating options besides tin?
A: Our standard offering for EV battery busbars is tin plating due to its suitability. Other plating options (such as silver or nickel) may be available for specialized applications and can be discussed upon request.
Q6: How do you ensure the electrical conductivity of the final busbar product?
A: Conductivity is ensured by using high-purity copper as the base material and by controlling the plating process to avoid excessive thickness that might impede conductivity. The MTR also confirms the material's quality. We can perform conductivity tests on finished products if specified.
Q7: What is your production capacity and lead time for custom orders?
A: With our team size and manufacturing setup, we can handle both small and large-volume orders. Lead times depend on order complexity and quantity. We provide estimated timelines upon receipt of detailed specifications.
Q8: Which markets do you primarily serve, and what are your main shipping ports?
A: We serve a global client base, including North America, South America, Europe, Asia, Africa, and Oceania. Our main shipment ports are Shanghai, Tianjin, Guangzhou, and Ningbo, facilitating efficient export logistics to various destinations.
