Abstract

This paper conducts an in-depth study on the challenges of low-temperature heating and thermal runaway management in lithium-ion batteries for new energy electric vehicles (NEEVs). First, the current research status of low-temperature heating for lithium-ion batteries is reviewed, analyzing the principles and practical effectiveness of existing heating methods, followed by a comprehensive synthesis of research findings. Subsequently, the control strategies for lithium-ion battery thermal runaway are systematically examined, including the mechanisms and hazards of thermal runaway, as well as the principles and practical performance of various mitigation approaches. Building on this foundation, the interplay between low-temperature heating and thermal runaway management is explored, and optimized measures for integrated management are proposed. Finally, the research outcomes are summarized, providing theoretical foundations and practical guidance for ensuring the safe operation of lithium-ion batteries in NEEVs under low-temperature conditions.
