Battery Management System Temperature Sensor

The battery temperature sensor uses a wire nose aluminum metal housing, which can protect the NTC chip well. On the other hand, the temperature of aluminum texture is fast. The thermal reaction rate of NTC is not affected.

The design of the front aperture of the aluminum shell with a diameter of 4mm ensures the thermal response of the NTC and is easy to install.

Using radial glass seal as the core temperature sensing element can ensure that it can work in high temperature environment on the one hand. (working at more than 150 degrees for a long time), on the other hand, the radial glass-sealed NTC thermistor burns the glass into a spherical structure, which tightly wraps the NTC thermistor chip. Its reliability is much higher than that of the package structure of axial glass seal. Thirdly, spherical radial glass sealed NTC thermistors have stronger mechanical stress resistance than axial glass sealed NTC thermistors. The fourth aspect, the radial glass sealed NTC thermistor size is smaller (the radial glass sealed NTC thermistor temperature sensor head size is only 1.3mm. The axial glass sealed NTC thermistor temperature sensor head size is 6mm. So although this structure is covered with an external copper shell. Its response speed is not greatly affected.

The product has small size, high voltage resistance and thermal response time.

Fast, wide operating temperature, good temperature measurement linearity, long working life and so on.
