CCS Cell Contact System (Integrated Busbar for Battery Packs)

Jingye New Energy is a Cell Contact System (CCS) manufacturer producing custom integrated busbars for EV and energy-storage battery packs. A CCS is a core component of the Battery Management System (BMS): by integrating signal-acquisition elements, plastic structural parts, and copper-aluminum busbars, it samples cell voltage and temperature and completes high-voltage series and parallel connections — improving battery pack space utilization and reliability. As a CCS busbar supplier, we offer full OEM/ODM design.

Key Functions

1. Connects cells to form the required system voltage and capacity — supports system voltages up to 1,000 V DC and current up to 500 A per busbar, for flexible series/parallel configurations in large battery modules.

2. Monitors each cell's voltage and temperature for the BMS — voltage accuracy ±5 mV per cell, temperature accuracy ±1 °C, sampling 1–10 Hz.

3. Integrated busbar design lowers resistive losses vs. wire harnesses — typical resistance reduction 30–50 mΩ per module, improving efficiency ~1–2% under high current.

4. Compact structure reduces wiring volume 20–30%, raising energy density in the same footprint.

5. Sealed, corrosion-resistant construction — IP65, operating temperature -40°C to +85°C, vibration up to 5 g RMS (10–500 Hz), cycle durability over 3,000 cycles.

Manufacturing Processes

We produce CCS using three processes — injection molding, thermoforming, and direct welding — up to a maximum size of 2000×800mm, compatible with the latest liquid-cooled battery packs. Each is customized to your cell layout, voltage platform, and module dimensions.

Why Choose a CCS over a Wire Harness

• Better sealing against humidity, oxidation, and corrosion
• Smaller and lighter — saves module space
• Faster, more consistent assembly than manual wiring
• Lower total cost in mass production

CCS Price & Quotation

As a direct CCS manufacturer with 2.4 million busbars/year capacity across 6 digital production lines, we quote by design and volume with fast, flexible engineering support. Send us your module drawings or requirements (cell type, cells in series/parallel, dimensions) for a design proposal and quotation.

What is a Cell Contact System (CCS)?

A Cell Contact System (CCS) is an integrated component that connects individual battery cells inside a battery pack. It combines busbars, signal-acquisition wiring, and an insulating carrier into one module, replacing traditional wire harnesses, and feeds cell voltage and temperature data to the BMS.

What types of CCS does Jingye manufacture?

Jingye produces CCS using injection molding, thermoforming, and direct welding, up to a maximum size of 2000×800mm, compatible with the latest liquid-cooled battery packs. Each is customized to your cell layout, voltage platform, and module dimensions.

Why choose a CCS over a traditional wire harness?

Compared with a wire harness, a CCS offers better sealing against humidity and corrosion, smaller size and lighter weight, faster assembly, and lower total cost at volume.

Can Jingye customize CCS for my EV battery pack?

Yes. We provide full OEM/ODM services — our team designs the CCS to your cell type, module structure, and communication requirements, then validates it in our CNAS-certified testing laboratory.
