Accuracy Temperature Control Escorts Fast Charging, Application of NTC Temperature Sensor in Charging Pile

With the iterative upgrading of EV fast charging technology, charging pile is moving towards high power. However, high-power charging causes the internal components of the charging pile to generate a lot of heat during operation, which has become a technical bottleneck that restricts the safe and stable operation of the charging pile and the improvement of charging efficiency. In this context, the EXSENSE charging pile NTC temperature sensor helps EV charging pile to monitor temperature and protect it from over-temperature by virtue of its high sensitivity to temperature changes, ensuring its stable operation.

In the high-power operation stage of EV charging pile, the temperature rise of internal components is fast, improper temperature control can easily lead to risks such as component aging, short circuit and even fire. The EXSENSE temperature sensor can assist the charging pile to collect temperature data at key parts in real time and transmit it to its control system, realize overheating warning and dynamic power regulation, and activate protection measures when the safety threshold is exceeded:

1. Internal power module of the charging pile: Install EXSENSE charging pile NTC on the surface of the module, which can obtain its junction temperature in real time, once the temperature is close to the preset temperature point, the charging pile control system will adjust the working frequency of the module in time or start the liquid cooling device, etc., to avoid damage to the power device due to overheating and ensure the stable power conversion efficiency.

2. Charging cable and interface: When charging EV, charging cable undertake the task of large current transmission. The charging interface is prone to poor contact due to frequent plugging and unplugging, which in turn causes local overheating. The NTC temperature sensor is embedded inside the cable connector and charging interface to collect temperature data in real time. The system adjusts the charging current based on these data to avoid abnormal temperature rise of cable and interface due to excessive current, ensuring the safety of the charging process.

To sum up, EXSENSE charging pile NTC temperature sensor does not work alone, but multi-faceted distributed temperature monitoring and over-temperature protection work on the charging pile, which depends on it:

1. Fast thermal response speed: the "fast catcher" of transient temperature rise

EXSENSE high-sensitive temperature sensor can quickly obtain the temperature change of each component of the charging pile in fast charging mode, and transmit the signal to the control system at the same time. This feature effectively avoids equipment failures caused by the accumulation of heat in charging pile, ensuring a balance between safety and efficiency in fast charging scenario.

2. High voltage resistance: the "safety weapon" of the high-voltage environment

EXSENSE temperature sensor has excellent electrical insulation and can adapt to the working environment of high-power DC charging pile, ensuring the stable operation of the temperature control system under high-voltage conditions.

The outstanding performance of the EXSENSE charging pile NTC temperature sensor makes it a crucial part of the temperature monitoring of EV charging pile. On the one hand, NTC constantly monitors the real-time temperature inside the charging pile, effectively reducing the accident rate caused by overheating and ensuring equipment safety. On the other hand, the high-accuracy temperature control capability of the EXSENSE charging pile NTC temperature sensor can slow down the aging speed of charging pile components, reduce equipment failure rate and maintenance costs, and thus extend the overall service life of the charging pile.
