Abstract:

Short cruising range and long charging time of electric vehicles seriously restrict their rapid development.To solve these problems,high-power fast charging of electric vehicles has revealed as an attractive strategy.Solving the thermal safety caused by high-power fast charging of lithium-ion batteries is an important prerequisite for supporting the development of fast charging.By summarizing home and abroad literature firstly, the mechanism of high power fast charging and thermal runaway of lithium-ion batteries is clarified.Secondly,starting from the optimization methods,liking fast charging strategy,battery design and manufacturing process,fast charging thermal management,etc.,the research progress of high power fast charging thermal runaway active prevention and control of lithium-ion batteries is stated,which provides the development ideas for thermal runaway prevention and control technology to accelerate the development of high power charging of lithium-ion powered batteries.

Key words: lithium-ion battery, fast charging, thermal runaway, lithium precipitation, thermal management, fire control
