What is the biggest enemy of electric vehicle EV batteries? Extreme temperatures.
Lithium-ion batteries perform best in a temperature range of 15-45℃. Temperatures above this temperature can severely damage the battery, while lower temperatures can reduce the output of the battery cells, thereby reducing the range and available power.
As the EV electric vehicle market grows, the EV temperature sensor Cable harness market will also grow with it. The reason is simple: just like vehicles with internal combustion engines, electric vehicles require high-performance and accurate temperature detection and sensor technology to ensure performance and safety.
“Charge for 5 minutes and travel 300km”, this sounds familiar, but this time the protagonist is Huawei, and Huawei’s recently launched super-fast charging pile is far ahead again. Huawei’s fully liquid-cooled super-fast charging pile adopts advanced liquid cooling technology, with the characteristics of efficient heat dissipation, fast charging, sicurezza e affidabilità.
Thermocouples are a commonly used temperature sensor based on the thermoelectric effect between two different metals. Thermocouples have a wide measurement range and good stability, and are suitable for temperature measurement in high temperature environments. Pellet stoves usually need to measure higher temperatures, so thermocouples are a common choice. Common types of thermocouples include K-type, N-type, and S-type, which can provide accurate temperature measurement in different temperature ranges.
Resistenze termiche metalliche come il nichel, I resistori di rame e platino hanno una correlazione positiva con la variazione della resistenza con la temperatura. Il platino ha le proprietà fisiche e chimiche più stabili ed è il più utilizzato. L'intervallo di misurazione della temperatura del resistore platino comunemente utilizzato PT100 è -200 ～ 850 ℃. Inoltre, La misurazione della temperatura varia di PT500, Pt1000, ecc. vengono successivamente ridotti. Pt1000, intervallo di misurazione della temperatura -200 ～ 420 ℃. Secondo lo standard internazionale IEC751, le caratteristiche di temperatura del resistore al platino Pt1000 soddisfano i seguenti requisiti:
