The role of NTC thermistor in lithium battery charging and discharge.Human Body Temperature Monitoring Sensor company

　　One of the most important components that allow lithium -ion batteries to charging quickly are NTC thermistor. NTC thermal resistance can ensure that the reason for safe and fast charging is to complete the critical temperature data required to maintain the best state of lithium ion during the charging cycle for users or systems. The use of NTC thermistor can protect the charger and extend the life of the battery and reduce risk.

　　Now turn on most modern household appliances, basically you will find a lithium -ion battery. The engineer gradually replaces the lead -acid battery with it when designing. Unlike conventional batteries, lithium -ion batteries will not establish memory when they are partially discharged or charged. It can also be completely discharged and charged thousands of times without affecting the overall performance. Lithium ion batteries are very important for green energy applications.

　　Lithium -ion battery charging is divided into four stages. Each type is slightly different:

　　1. Charging is a necessary step to enter the standby mode for a long time. The most common is that portable and desktop computers need this type of charging.

　　2. Saturation is the stage where the voltage is kept at its maximum set point. Over time, charge will be reduced.

　　3. When the charging current drops to less than 4 % of the battery rated output current, the voltage will be turned off when the charging is prepared.

　　4. When the voltage rises to the maximum set point, the pre -charging is a constant current.
