Abstract: Under high-current charging conditions, the terminal contact resistance of NEV DC charging guns generates heat that causes temperature to rise rapidly. Without reliable temperature monitoring and over-temperature protection, there

When sourcing automotive temperature sensors, suppliers always claim their NTCs are “automotive-grade.” But what are the actual hard metrics behind that label? Which checkpoints does AEC-Q200 certification enforce? And what

Core Summary: 800V high-voltage fast-charging platforms are becoming the mainstream architecture for new energy vehicles, bringing new challenges to temperature sensors. Compared to 400V platforms, 800V platforms raise NTC temperature sensor

Core Summary: The most commonly used NTC resistance values in BMS are 10K and 100K, and many engineers don’t know how to choose. This article systematically compares both across five dimensions:

Core Summary: Energy storage systems contain tens of thousands of cells, and temperature monitoring is the lifeline of safe operation. How NTC sensors are arranged, how many sampling points are needed,

Core Summary: The BMS is the brain of safe battery system operation, and temperature monitoring is one of its core functions. NTC thermistors are the preferred solution for BMS temperature measurement

Core Summary: The R-T relationship of NTC thermistors is nonlinear. Engineers commonly use the B-value formula for temperature conversion, but it has significant errors over wide temperature ranges. The Steinhart-Hart equation

Core Summary: NTC accuracy specifications are usually written as “R25 accuracy ±1% / B-value accuracy ±1%”. Many engineers don’t know what temperature error this corresponds to. In practice, ±1% resistance accuracy

Core Summary: When NTC thermistors are powered, they generate Joule heat (P=I²R), causing their temperature to rise above ambient — this is the self-heating effect. Dissipation factor δ (unit: mW/°C) reflects

Core Summary: Thermal time constant τ (tau) is the core metric for measuring temperature sensor response speed. It is defined as the time required for a sensor to reach 63.2% of

Core Summary: SMD and through-hole NTC thermistors share the same core chip, but differ in heat dissipation, power, size, and soldering process due to package form. SMD NTCs are compact and

Core Summary: NTC, PTC, RTD (PT100), and thermocouples are the four mainstream temperature sensors in industry. NTC offers low cost and sufficient accuracy — the first choice for BMS and home

Core Summary: NTC thermistors and thermocouples are two temperature sensors with fundamentally different working principles. Thermistors are suited for mid-to-low temperature (−40 to 150°C) high-accuracy measurement with low cost and no

Core Summary: NTC thermistors and RTDs (PT100/PT1000) are two common temperature sensors. The core difference lies in the trade-off between accuracy and cost. PT100 achieves ±0.15°C accuracy but costs ¥5-30; NTC

Core Summary: PPTC (Polymer Positive Temperature Coefficient) self-resetting fuses are reusable overcurrent protection components. When a fault occurs, their resistance surges to cut off current; once the fault is cleared, they

Core Summary: At the moment a switching power supply turns on, the filter capacitor acts as a near-short circuit, generating an inrush current tens of times the rated current that can

Core Summary: In temperature measurement applications, NTC thermistors are the first choice for most scenarios due to their smooth and continuous R-T curve, high measurement accuracy, and low cost. PTC thermistors

Core Summary: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient) thermistors are two common temperature-sensitive components, but their working principles, material properties, and application scenarios are fundamentally different. NTC resistance
