Abstract：The serious lithium plating, high internal impedance and available capacity plummeting of the battery at low temperature condition lead to the shortage of energy, performance degradation and the aggravation of the potential safety problems. Aiming at the problem that the heating speed under low temperature condition of lithium-ion battery is slow, which restricts the application in the all-climate environment. The characteristics of extremely fast heat generation by electric trigger heating method are discovered, by which an intermittent fast heating system for battery is developed. A systematic heating experiment is designed to study the extremely fast heat generation behavior, and the effects of heating frequency, duty cycle and initial state of charge on the temperature rise and safety of the battery are clarified. It is found that the heating temperature rise has obvious positive correlation with duty cycle and initial state of charge. The current of the heating cycle is the key factor for the temperature rise. Therefore, the accurate control of the current is the basis of the low temperature heating. The electrochemical thermal coupling model of heating at low temperature is established, and the lithium-ion concentration distribution of the particles during the heating process is analyzed. The results show that the extremely fast heating method adopted will not affect the overall recyclable lithium-ion concentration of particles, and the effects of heating frequency and duty cycle on heating are verified.
