CCS Introduction
CCS (Cells Contact System) integrated busbar, also known as battery cover assembly, is a module that integrates the conductive rows, control circuits (voltage and temperature acquisition) and other components of the battery module into one module to realize the high-voltage series-parallel connection of the cells, as well as the temperature sampling of the battery, cell voltage sampling, and over-current fusing, and to provide the temperature and voltage to the BMS system through the FPC, PCB, etc. and the connector components to the BMS system, which is part of the BMS system.
CCS integrated busbar advantages:
1. Simple production and processing, high degree of automation, saving assembly labor costs, avoiding the tediousness of too many connections in the wiring harness.
2. One-piece hot press molding, line sealing, oxidation resistance, corrosion resistance, high reliability;
3. FPC/PCB lines have over-current protection design to protect the battery cell, high safety performance;
