Redefining The Battery Nervous System: Arida Integrated Breakthroughs in CCS And BMS Data Acquisition

In the design of Electric Vehicle (EV) battery packs, traditional wire harnesses are rapidly being replaced by the Cell Contact System (CCS). This lightweight, automated integration solution is often referred to as the "nervous system" of the battery pack.

Arida has keenly grasped this trend. Relying on robust capabilities in precision stamping and injection molding, we provide BMS (Battery Management System) developers with a one-stop solution ranging from FPC acquisition nickel tabs to engineering plastic brackets.

1. The Evolution of Acquisition: FPC Specialized Nickel Tabs

The core of CCS lies in using Flexible Printed Circuits (FPC) to collect voltage and temperature signals from battery cells. However, this introduces a process challenge: How to reliably connect copper FPCs to aluminum or steel-shelled battery cells?

Arida provides the answer with Customized FPC Connection Nickel Tabs.

Dissimilar Metal Connection:

Our specialized nickel sheets or copper-nickel composite tags act as a bridging interface between the FPC and the battery cell, solving welding compatibility issues.

Structural Adaptability:

Targeting different Pack structures, Arida can produce L-shaped, U-shaped, or complex multi-bent nickel structures. We maintain a dimensional tolerance of +/- 0.05mm, ensuring these tags can be precisely mounted onto FPC pads without manual calibration.

2. Dual Armor of Metal + Plastic: PPS/PPA Injection Molding

Beyond metal connections, CCS modules require plastic trays for fixation and insulation. Unlike standard injection molding factories, Arida has deeply invested in a New Energy PPS/PPA Plastic Product Line.

High Temperature and Flame Resistance:

We select high-performance engineering plastics like PPS (Polyphenylene Sulfide) and PPA (Polyphthalamide). These materials maintain extreme dimensional stability even in the harsh internal environment of a battery pack (-40C to 125C).

Precision Fitting and Insert Molding:

Arida's injection molding machines are equipped with algorithmic coordinate compensation. This allows us to produce battery brackets with complex snap-fit structures. We can even achieve Insert Molding, where metal busbars are directly embedded into the plastic bracket during the molding process, significantly reducing assembly steps for our customers.

3. Aluminum Busbar and High Current Transmission

While nickel tabs handle signal acquisition, Arida also focuses on energy transmission. For the main power circuit of power batteries, Arida offers New Energy Aluminum Busbar Products.

Compared to traditional copper busbars, aluminum busbars reduce weight by approximately 40% while maintaining sufficient ampacity. Arida employs advanced laser welding and stamping processes to ensure the contact surface between the aluminum bar and the battery pole is extremely flat. This effectively reduces contact resistance and minimizes heat loss under high currents.

4. Why Choose Arida Integrated Solution?

For battery Pack manufacturers, fragmented procurement (buying nickel from one supplier, plastic from another, and FPCs from a third) often leads to huge communication costs and the risk of tolerance stack-up.

Arida has achieved an internal closed loop of Stamping + Injection Molding + Cleaning + Surface Treatment.

Collaborative Design:

Our metal mold and plastic mold teams work in synergy, ensuring a perfect match between metal inserts and plastic components.

Unified Standards:

The entire process follows the IATF16949 system. From the conductivity of raw metal materials to the flame retardancy rating of plastic parts, we execute a unified quality control standard.
