Battery CCS

A Battery CCS (Cell Contact System) is a critical integrated component used in modern lithium battery packs for electric vehicles (EV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), and Energy Storage Systems (ESS). It combines electrical conduction, voltage sampling, temperature monitoring, and signal transmission into one compact assembly, enabling safer, lighter, and more efficient battery pack designs.

At G&N Fortune Limited, we specialize in manufacturing custom Battery CCS solutions, including EV battery busbar assemblies, FPC CCS systems, and integrated Cell Contact Systems for EV batteries.

What Is Battery CCS?

Battery CCS (Cell Contact System) is an integrated electrical connection system used inside lithium battery packs. It connects individual battery cells and communicates with the Battery Management System (BMS).

A typical Battery Cell Contact System includes:

• Copper or aluminum Busbars

• Flexible Printed Circuit (FPC CCS)

• Voltage sampling circuits

• NTC temperature sensors

• Cell contact plates

• Connectors

• Insulation layers

• Plastic carrier structure

The main purpose of a Battery CCS for EV Battery is to replace traditional wire harness systems, reducing complexity while improving performance and reliability.

How Does Battery CCS Work?

The working principle of a Battery CCS Assembly is based on five key functions:

Current Transmission

The battery Busbar assembly connects cells in series or parallel to ensure stable current flow with minimal resistance.

Voltage Sampling

The FPC CCS system collects voltage data from each individual cell and sends it to the BMS for real-time monitoring.

Temperature Monitoring

NTC sensors integrated into the CCS continuously monitor cell temperature to prevent overheating and thermal runaway.

Signal Communication

All voltage and temperature data is transmitted to the Battery Management System for balancing and control.

Safety Protection

Some Battery CCS designs include fuse or protection structures to improve battery safety in abnormal conditions.

Battery CCS vs Traditional Wire Harness

Compared with traditional wiring systems, Battery CCS for EV battery packs offers:

• Higher integration level

• Reduced wiring complexity

• Lower assembly cost

• Better reliability

• Lighter weight

• Higher automation compatibility
