Thermistor effect in rechargeable battery

Thermistors are a class of sensitive components that are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to the temperature coefficient. Thermistors are typically characterized by temperature sensitivity and exhibit different resistance values at different temperatures. So what is the role of the thermistor in the rechargeable battery?

Reasons for adding a ntc thermistor to a rechargeable battery pack:

Because the rechargeable battery may cause the battery temperature to be too high during continuous cycle charging and discharging, the original performance of the battery is degraded. In order to maintain battery performance, it is important to closely monitor the battery temperature. NTC can be used for temperature monitoring, control, and compensation in suitable applications within the rechargeable battery pack.

Using NTC thermistor to monitor the temperature of the battery, you can safely control the charging and discharging of lithium or nickel-metal hydride batteries. The NTC functions are as follows:

1, can guarantee the design cycle life of the battery.

2, the battery can be more economical to charge.

3. The accurate temperature measurement of the thermistor is an important auxiliary component for displaying the remaining time of the battery.

Based on the above advantages, it is recommended to use a thermistor in the rechargeable battery to ensure the performance and security of the battery.
