description The invention discloses a lithium battery protection system, a chip system and a method, the lithium battery protection system comprises a reference voltage module, a bias current module, a comparator module, an oscillator module and a logic processing module, and the chip system adopts the lithium battery protection system according to claim 1 and comprises a TEMP pin. The interior of the TEMP pin is connected to a temperature sampling area of a temperature conversion module through a heat conduction metal wire, the temperature conversion module converts the temperature into a voltage signal in real time, and the method comprises the following steps:the TEMP pin is led out, the interior of the TEMP pin is connected to the temperature sampling area of the temperature conversion module through a heat conduction metal wire, and an external heat energy signal is conducted to a chip internal temperature sensing circuit sampling area. According to the invention, when the temperature of the lithium battery changes
