How PTC Thermistors Work
Jun 29 , 2023
How Thermistors Work The thermistor will not operate for a long time; when the ambient temperature and current are in zone c, the heat dissipation power of the thermistor is close to the heat generation power, so the thermistor may or may not operate. When the thermistor is in the same ambient temperature, the action time is sharply shortened with the increase of current; the thermistor has a shor...

PTC Thermistor
Jun 28 , 2023
PTC (Positive Temperature Coeffi Cient ) PTC is a thermistor with a positive temperature coefficient and a sharp increase in resistance at a certain temperature. thermistor phenomenon or material that can be used specifically as a constant temperature sensor . RT and RT0 indicate the resistance value at temperature T and T0, and Bp is the material constant of the material. The ...

Temperature Sensor Concept
May 19 , 2023
1、Temperature Temperature is a physical quantity that indicates the degree of heat and cold of an object. Microscopically, it is the intensity of the thermal motion of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of the object as it changes with temperature, and the scale used to measure the value of the object's temperature is called the tempe...

New energy vehicle battery temperature management and temperature sensors
Apr 26 , 2023
What is the biggest enemy of electric vehicle batteries? Extreme temperatures. Lithium-ion batteries perform best in the 15-45°C temperature range. Temperatures above that can severely damage the battery, while lower temperatures can reduce the output of the battery cells, thus reducing range and available power. The thermal management system always works to monitor or maintain the internal batter...

What is the difference between 2, 3 and 4 wire RTD temperature sensing?
Mar 31 , 2023
What is the difference between 2, 3 and 4 wire RTD temperature sensing? The difference between 2, 3 and 4 wire RTD temperature sensing is the accuracy of the measurement. Using 2 Resistance Temperature Detector (RTD) sensing provides good accuracy (possibly), 3-wire sensing provides better accuracy, and 4-wire sensing provides the best accuracy. There is also the option of using a Wheatstone bridg...

Electric Vehicle Thermal Management System
Mar 31 , 2023
Electric Vehicle Thermal Management System TMS is generally used for batteries that operate at high discharge rates, especially large battery packs that require long life cycles (>10 years) and are costly to replace. For example, due to high battery maintenance costs, high vehicle costs per SE and relatively low vehicle replacement rates, all HEVs, PHEVs and EVs must be equipped with a T...

Battery pack sensor applications for new energy vehicles
Mar 31 , 2023
Battery pack sensor applications for new energy vehicles New energy vehicles all have the same characteristic - they all have battery packs. The internal structure of the battery pack is similar in that they all have a battery, a box for the battery, a high-voltage wiring harness, a low-voltage wiring harness, a high-voltage isolation system, a battery management system, a thermal managemen...
