Custom NTC Temperature Sensor For Battery Temperature Detection Of
New Energy Vehicles
NTC temperature sensor is a kind of thermistor and probe. Its
principle is: the resistance value drops rapidly as the temperature
rises. It usually consists of 2 or 3 metal oxides, mixed in a
fluid-like clay, and calcined in a high-temperature furnace to form
a dense sintered ceramic. Actual size is very flexible, they can be
as small as 0.010 inches or very small diameter. There is almost no
limit to the maximum size, but usually under half an inch applies.

Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the
resistance value drops rapidly as the temperature rises. Utilizing
this feature, the NTC thermistor can be used to determine the
corresponding temperature by measuring its resistance value, so as
to achieve the purpose of detecting and controlling the
temperature.
