Designed for electric vehicles (EVs) and energy storage systems
The Cell Contact System (CCS) plays a vital role in power battery modules, air-cooled and liquid-cooled mass-storage battery modules, and residential energy storage battery modules. It facilitates key operations such as sensing battery temperature, monitoring individual cell voltage, and establishing high-voltage series or parallel connections between cells. A notable design within CCS is the Semi-Covered Insulating Film Structure, which provides the essential electrical and electronic interface connecting individual battery cells to the Battery Management System (BMS), particularly in applications like electric vehicles (EVs) and energy storage systems (ESS).
Design properties
In this design, the insulating film doesn’t entirely encapsulate all the conductive parts of the CCS. Instead, it covers specific areas, leaving other parts exposed for connection or other functional reasons.
Possible Reasons for a Semi-Covered Design
- Connection Points: Certain areas of the busbars or the PCB/FPC need to be exposed for welding to the battery terminals or for connecting to the BMS. A semi-covered film allows for this direct access.
- Thermal Management: Leaving some areas uncovered might aid in heat dissipation from the cells or the conductive components.
- Assembly Efficiency: A semi-covered design could simplify the automated assembly process by providing easier access for certain steps.
- Cost Optimization: Using less insulating film material can contribute to lower manufacturing costs.
- Integration of Other Components: Exposed areas might be needed for integrating other elements like sensors or fuses directly onto the CCS.
Contrast with a Fully Covered Insulating Film Structure
A fully covered insulating film structure would imply that all conductive parts of the CCS are completely encapsulated by the insulating film. This would offer maximum electrical insulation but might present challenges for making electrical connections and managing heat.
