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...

Electric vehicle sensors need to monitor fast charging
Mar 31 , 2023
Electric vehicle sensors must monitor fast charging The safe and efficient starting and stopping of fast EV charging is ensured by sensor technology. Fast charging requires fast-responding sensors - primarily vehicle temperature sensors. Without real-time monitoring to trigger the system to maintain the ideal temperature, the risk of thermal damage to EV components increases dramatically. EVs need...

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...

Temperature control method in cold chain transportation of vaccines and other drugs
Feb 27 , 2023
The most important thing for cold chain transportation is temperature control in the process of transportation. Temperature monitoring is controlled by a temperature controller. Long-distance transportation is usually equipped with a GPS temperature monitoring system, so that the temperature changes can be seen in real time in the office. Usually a refriger...

New energy step battery and temperature sensor
Feb 22 , 2023
The recycling of lithium batteries refers to the centralized recycling of lithium batteries that are about to be scrapped, and the recycling of batteries through physical, chemical and other recycling processes, or the extraction of valuable metal elements in batteries, and the re-application of lithium batteries and other fields. The internal development of the b...

Application scenarios and design requirements of new energy harness
Feb 22 , 2023
There are many wire harnesses in automobile. Electronic control system is closely related to wire harnesses. Someone once made an image analogy: if the function of microcomputer, sensor and executive element is compared with the human body, it can be said that the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, the executive...
