Research On Risk Management Strategy Of A Company’s Power Battery Thermal Management Technology R＆D

As the planet’s energy shortage intensifies,emphasis is being placed on scientific and intelligent use of energy in the production,storage,transportation,use and recycling of energy.Coal-based "carbon-based" energy sources are decreasing,and one or more clean or renewable energy sources are urgently needed to replace traditional fossil energy sources.To this end,countries around the world are actively developing new energy industries,and China has also adopted a series of policies to support efforts from energy technology to energy management in the direction of intelligent use of energy.Fuel cars,as one of the traditional energy consuming devices,are already gradually being converted to electric vehicles.Lithium-ion batteries stand out for their high energy density,long range and no memory effect.However,lithium-ion batteries are quite sensitive to their operating temperature,so lithium-ion battery thermal management systems are vital for power batteries.The heat dissipation of Li-ion batteries can be divided into air-cooled heat dissipation,direct-cooled heat dissipation,liquid-cooled cycle heat dissipation and other methods.The liquid cooling cycle is widely used for its large heat transfer area,high heat transfer efficiency and easy integration of heating systems.In addition,the rapid charging strategy is the development demand of modern society.The temperature of lithium batteries will rise sharply when they are charged quickly,which will cause performance degradation or even the risk of thermal runaway.For this reason,ensure that the lithium battery can work in a safe temperature range without thermal runaway.,Safe and efficient power supply for electric vehicles,new energy power battery thermal management system design is already an indispensable and important part.Based on the premise of no environmental risk,market risk,economic risk,policy risk,and meeting laws and regulations,this article will start from the perspective of management,at the level of technology research and development,using fuzzy evaluation method,expert survey method,statistical analysis method,etc.Identify the R＆D risks of lithium battery thermal management system.According to the identified risks,improve the risk control system through three perspectives before,during and after the risk;at the same time,optimize the research and development process,control the process deviation,and control the project decision and information feedback to optimize the risk control process;Finally,by optimizing the organizational strategy,a complete project development team was formed;to ensure the smooth progress of the power battery thermal management system research and development project and delivery on schedule;the goal of reducing,avoiding,and transferring risks has been achieved to ensure the use of new energy vehicle power batteries for customers Personal and property safety.
