With the rapid development of new energy vehicles, the safety and stability monitoring of battery packs has become a key issue. Among them, battery temperature management is one of the important measures to ensure the long-term stable operation of the battery pack and improve the service life of the battery pack. Due to its temperature-sensitive nature, NTC thermistor works with CCS cell contacting system to provide excellent protection for operation of battery pack.

In the design scheme of CCS, the NTC thermistor is typically mounted on the FPC, and the FPC is set on the battery cover and electrically connected directly to the battery. When the battery pack starts working, NTC starts to measure the temperature in real time to provide accurate temperature data for the BMS battery management system. On the one hand, the BMS will evaluate the operating temperature and status of the battery pack in real time according to the temperature data provided by the thermistor, so as to prevent the battery pack from overheating during the charging/discharging process and prolong its service life. On the other hand, the real-time temperature measurement of the thermistor can also help the BMS detect the abnormal temperature rise of the battery pack in time, and trigger the corresponding safety protection mechanism, effectively prevent thermal runaway accidents and ensure the safe operation of the battery pack.

With the help of NTC thermistor, the battery pack can adjust its operating state in real time to ensure that it is in the optimal operating temperature range. In order to cooperate with the CCS for technical upgrading and ensure the stable operation of the battery pack, EXSENSE Electronics Technology Co., Ltd. has developed and mass-produced CT series SMD type NTC thermistor, which:

First, high accuracy, to achieve accurate monitoring of the temperature of the battery pack, which is of great significance for improving the safety of the battery pack and prolonging its service life;

Second, excellent reliability, stable electrical performance can be maintained in extreme environments, and can adapt to the temperature measurement requirements of battery packs in different states;

Third, small size, millimeter-level size can save the installation space of the CCS and improve the overall integration of the battery pack.

SMD type NTC thermistor is an indispensable part of the battery management system, which significantly improves the safety and reliability of the battery pack through reasonable structural design and installation methods, and realizes accurate monitoring and safety control of battery temperature.
