The Functions of NTC Thermistor in Battery

Nov. 29, 2021

With the development of new energy, new energy power batteries and rechargeable batteries have been widely used in automobiles, appliances, and household appliances due to their excellent characteristics. This article will tell you about the thermistor's role in the battery. Let's learn about it together.

In recent years, there have been many problems about charging accidents every year. Taking into account the issue of security, everyone's quality requirements for the selection of products have also been continuously improved. As the rechargeable battery is continuously cyclically charged and discharged, the temperature of the battery may be too high, resulting in a decrease in the original performance of the battery.

The reason why NTC thermistor is used in the rechargeable batteries is that it can play a role in temperature monitoring, control and compensation. The main functions of the NTC thermistor in the battery are as follows:

1) The design life cycle of the battery can be guaranteed.

2) The battery can be charged more economically and efficiently.

3) Thermistor temperature measurement is an important auxiliary element to display the remaining battery time.

The Functions of NTC Thermistor in Battery

In addition to temperature monitoring, control, and compensation, thermistor also has good stability and strong overload capacity. It is small in size and can measure the temperature of voids, cavities and blood vessels in organisms that other thermometers cannot measure. The sensitivity is high, the temperature coefficient of resistance is more than 10-100 times larger than that of metal, and the temperature change of 10-6℃ can be produced.

Therefore, the thermistor is used in the rechargeable battery to ensure that the battery maintains performance and security, in order to stably monitor the temperature of the rechargeable battery pack and protect life safety. If you don’t know how to choose thermistor, you may go for NTC thermistor developed and produced by Dongguan Zhixu Electronic Co., Ltd. (also JYH HSU(JEC)).
