Car Battery Temperature Measuring Injection Silicone NTC Temperature Sensor 4.7k Ohm 3470
Description Of The NTC Temperature Sensor 4.7k Ohm 3470
With the widespread application of electric vehicles, people have higher and higher requirements for battery safety. As a parameter to measure battery status, temperature is an important monitoring object for battery safety. Traditional temperature sensors have problems such as large volume and complicated packaging. Due to this limitation, the prior art can only monitor the overall temperature of the battery box, and cannot perform differential temperature monitoring on a single battery.
