In addition to the +, - pole on the battery, what is the meaning of a T

- Sep 10, 2019-

T is the abbreviation of Thermal, mainly used to monitor battery and PCM temperature;

The T terminal is connected with a temperature sensitive resistor on the PCM in the battery. It is mainly used to monitor the battery and PCM temperature, and send the temperature signal to the load controller for processing. If the battery and PCM temperature are too high, charging and discharging are prohibited.

In fact, there is no use, reserved as battery information detection.

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912.

In the 1970s, M. S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment.
