Thermistor is an abbreviation of Thermally Sensitive Resistor. It is an electrical device that capitalizes on the material resistances that change with the temperature. The resistance of this thermistor decreases when the temperature increases, which is why the product is called a negative temperature coefficient (NTC) thermistor. NTC thermistors are widely used for temperature measurement/compensation in places where a temperature control is required.
The water temperature sensor (WTS) is mainly installed in the cooling water passage of the cylinder block or cylinder head to measure the coolant temperature of the engine. NTC thermistors are used for this purpose; the resistance of the NTC thermistor decreases when the temperature rises. The fuel injection amount is corrected by accurately determining the engine's operating state.
It is a sensor that prevents short circuits and/or explosions caused by overheated batteries in an EV; due to the temperature changes in the lithium ion cells, EV batteries can be overheated. It also maintains the constant temperature of BMS by sensing the battery temperature. With a built-in NTC thermistor, this sensor makes it possible to measure the temperature of the cells and convert it into a resistance value.
Thermistor is an abbreviation of the Thermally Sensitive Resistor. It is an electrical device that capitalizes on the material resistances that change with the temperature. The resistance of this thermistor increases with the temperature, which is why the product is called a positive temperature coefficient (PTC) thermistor. When electricity is applied, the PTC prevents the current in the circuit from rising above a certain level so that the heater heats up to the set temperature.
