Increased battery density is the endgame of all cutting-edge battery design, improvements cannot come at the expense of safety or cost limitations. The question then becomes how to push the envelope in a safe and cost-effective way. Monitoring the state-of-health of cells is at the top of the list of considerations.
Accurately measuring ambient factors like temperature and voltage provides critical data to the BMS. For years, this could be done through discreet wiring, though this method was inefficient, and quality was lacking. In today’s designs, flexible PCBs are taking the place of discreet wiring. These FPC-based systems are the newest generation of Cell Contacting Systems. They simultaneously bring down the cost of pack manufacturing and improve reliability in manufacturing and data harnessing.
Quality of data is essential in order to safely maximize energy density. This white paper from Churod Electronics details the hows and whys of FPC-based Cell Contacting Systems and how this cost-effective, yet reliable tool is a key to modern battery pack efficiency.
