　　What is the significance of research on the state of health of lithium-ion batteries

　　Lithium battery state of health research significance Battery SOH represents the ability of the current battery to store electrical energy relative to a new battery, and expresses the state of the battery from the beginning of its life to the end of its life in the form of a percentage, which is used to quantitatively describe the performance state of the current battery. ① Significance to battery management Battery management system estimates battery

　　Significance of research on state of health of lithium-ion batteries

　　The battery SOH represents the ability of the current battery to store electric energy relative to the new battery, and expresses the state of the battery from the beginning of the life to the end of the life in the form of a percentage, which is used to quantitatively describe the performance state of the current battery.

　　① Significance to battery management

　　The battery management system estimates the state of charge and remaining power of the battery are related to the capacity of the battery. If the lithium-ion battery management system can grasp the aging law and health status of the battery, it will help it manage the battery throughout the life cycle of the battery.

　　② Significance to battery use and maintenance

　　SOH research is conducive to mastering the factors affecting battery aging and providing theoretical guidance for the use and maintenance of lithium-ion batteries. For the use and maintenance of batteries, understanding the factors that affect battery aging can reduce the damage to battery usage such as high and low temperature, overcharge and overdischarge; knowing the current health status of the battery can help judge the internal hidden dangers and life of the battery. Provides reference for battery maintenance and replacement.

　　③ Significance to battery economic evaluation

　　The accurate evaluation of SOH is of great significance to the economic evaluation of lithium-ion batteries. Different application scenarios, usage methods, and maintenance methods of lithium-ion batteries cause differences in battery life, which makes economic evaluations such as battery use costs and economic benefits different. The aging model of batteries is established through SOH research, which provides data support for analyzing the economics of batteries, and provides effective assistance for company investment decisions, government policy formulation, and industrial development planning.
