At present, in the field of energy storage, the use and development of lithium batteries are very rapid. As a series and parallel components between battery packs, connectors play a very important role. Now，Elecbee engineers will introduce you to lithium batteries in energy storage systems. I hope it can help you with the knowledge of batteries.
Lithium battery energy storage has the advantages of high energy density, long service life, and environmental protection. Lithium battery energy storage is an inevitable trend of the development of the times, and ensuring the safe and reliable operation of lithium batteries is the primary condition for the operation of energy storage systems.
When the battery pack is charged and discharged, the passing of a large current will cause the connector to produce a thermal effect. When the temperature of the connector rises and exceeds the temperature of the battery pack, the temperature will be transmitted to the inside of the battery, which will affect the stability of the battery. It has become a necessary condition for the connector to achieve low temperature rise characteristics. In the lithium battery energy storage system, the temperature sensitivity of the lithium battery mainly comes from the temperature sensitivity of the material’s physical and chemical properties. Temperature will directly affect the activity and conductivity of the electrode material, the insertion and deintercalation of lithium ions on the electrode, the lithium ion permeability of the separator, etc., and then affect the electrochemical reaction inside the battery, and its external performance is the temperature of the power battery Sensitivity.
In addition, the long-term uneven distribution of the temperature field inside the battery box will also cause the imbalance of the performance of each battery module and cell, especially the aging rate of the battery distributed in the high-temperature area will be significantly faster than the low-temperature part, as time accumulates The difference in physical properties between different batteries will become more obvious, which will make the consistency between the batteries worse, and even premature failure occurs, shortening the life of the entire power battery system.
