CCS (Cells Contact System), also known as a wiring harness board integrated component, is composed of signal acquisition components (wiring harness/FPC/FFC, etc.), plastic structural components, copper aluminum bars, etc. connected into a whole through processes such as hot pressing or riveting, to achieve high-voltage series parallel connection of battery cells, as well as temperature sampling and voltage Sampling function ng mga cell ng baterya. Nickel Sheet Ito ay bahagi ng sistema ng BMS at maaaring magamit sa mga patlang tulad ng mga bagong baterya ng lakas ng enerhiya at mga baterya ng imbakan ng enerhiya.
