In electric vehicles, temperature monitoring of all power components is a basic requirement for ensuring the safety, reliability and longevity of the entire system. Robust TDK and EPCOS NTC temperature sensors available in a wide range of different designs are key components for this task.
The increasing trend towards xEV is forcing both the automotive industry and its suppliers to rise to new challenges. One particular challenge is the fact that the short charging processes involved in the charging of xEV batteries require a high charging output that is well into the three-figure kW range. This can lead to heating/overheating of the components involved in the charging process. Therefore, appropriate temperature monitoring of the charging station, the connector system, the busbars, the power electronics and the high-voltage battery is a basic requirement for ensuring that the charging process can be performed safely and efficiently. Insufficient temperature monitoring can lead to wear of the system components, reduced service life, or even failure of the components. In a worst-case scenario, major overheating can cause the battery to catch fire.
TDK has developed a range of special NTC temperature sensors for temperature monitoring in E-mobility applications. These sensors enable outstanding temperature monitoring thanks to their high levels of reliability and precision. This makes it possible to optimize the charging process, to increase the life time of the components subjected to thermal loads and implement safety-related functions. These NTC temperature sensors also stand out thanks to a high measurement accuracy and short response times. They are ideally suited to the monitoring of thermal processes involved in the charging process.
