AI Technical Summary
In existing technologies, the sensors are easily damaged by compression when the battery pack is placed, affecting the stability and lifespan of the detection.
The device employs a liftable lower pressure plate and an elastic telescopic rod combined with a temperature sensor. The lower pressure plate is lowered by an electric push rod, allowing the sensor on the elastic telescopic rod to fit against the surface of the battery pack. Combined with the cooling pad and fin structure, it achieves rapid cooling.
It improves the accuracy and stability of battery pack temperature detection, avoids sensor damage, and can quickly cool down, thus improving detection efficiency.
