What is the role of NTC (T port) for power lithium battery protection board?

The supplier of the power battery battery supplier protection board The supplier of the protection board is a necessary equipment to enhance the safety of the power lithium-ion battery supplier. In most cases, the lithium battery protection board should have the function of controlling the working conditions of the lithium-ion battery. These working conditions include voltage, current, temperature, etc. Due to the particularity of the use of lithium-ion batteries, the power lithium-ion battery must be used together with the protection board to ensure the safety and reliability of the entire system. Today, the Chinese Chuangfa will learn with you the role of the power lithium battery protection board NTC (T port)?

When the battery is working, there is no overcharge, overdischarge or overcurrent, short circuit, etc., but because the working time is too long, the temperature of the battery core rises (for example, we usually use mobile phones to talk on the phone. )quickly. The NTC resistor is close to the battery cell to monitor the temperature of the battery cell. As the temperature rises, the NTC resistance value gradually decreases. The consumer CPU notices this change. When the resistance value drops to the set value of the CPU, the CPU sends a shutdown command to stop the battery. Powering it, only maintains a small standby current, to achieve the purpose of protecting the battery.
