Battery core thermal runaway simulation circuit and method

The invention relates to the technical field of battery simulation, and provides a battery core thermal runaway simulation circuit, which comprises a battery core and a triode arranged in an electrolytic solution of the battery core, wherein the collector of the triode is connected with the anode of the battery core, the emitter of the triode is connected with the cathode of the battery core, andthe base electrode of the triode is led out to serve as a leakage resistance adjusting control end. The invention further provides a corresponding battery core thermal runaway simulation method and abattery core thermal runaway simulation system. According to the embodiment of the invention, the thermal runaway is simulated by embedding the battery core into the high-power triode, and the thermalrunaway triggering energy is completely from the battery core and the interior of the battery core, so that the thermal runaway process can be triggered more truly; the whole process of thermal runaway caused by internal short
