NTC Thermistors in Lithium Battery Protection Circuits

NTC (Negative Temperature Coefficient) thermistors are indispensable temperature sensing components in lithium battery protection circuits. In Battery Management Systems (BMS), NTCs monitor battery temperature in real time, triggering protection mechanisms when temperature rises abnormally to prevent thermal runaway. Key selection criteria include B-value accuracy, rated resistance and package type. Lixing Tech NTC series achieve B-value accuracy of ±0.5%, widely used in consumer electronics and electric vehicles.
