Information

Energy storage connector manufacturers tell you that in the field of energy storage, the application and development of lithium batteries are very sensitive. Lithium battery energy storage has the advantages of high energy density, long service life, and environmental protection. However, there are also some disadvantages and high production costs. The safety function is poor and there is a danger of explosion. Therefore, the safety planning of the heat treatment system is very important for the application of lithium batteries. The energy storage connector manufacturer tells you that the connector is an indispensable component between the series and parallel connections of the battery pack. The temperature rise effect has a great impact on the entire lithium battery energy storage system, so low temperature rise planning has become an inevitable trend in the development of connectors.

Energy storage connector manufacturers tell you that in lithium battery energy storage systems, the sensitivity of lithium batteries to temperature is mainly due to the temperature sensitivity of the physical and chemical properties of their materials. 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 internal electrochemical reaction of the battery, and its external performance is the temperature of the power battery Sensitivity. The Energy storage connector manufacturer tells you that because the power battery has a suitable operating temperature plan, as the temperature increases in this plan, the greater the activity of its internal active materials, the higher the charge and discharge voltage and capacity of the battery. The internal resistance of the battery will decrease accordingly. , The charging and discharging power of the power battery also increases accordingly. However, when the temperature exceeds a certain plan, too high a temperature will accelerate the progress of the secondary reactions within the battery, which consume lithium ions, solvents, and electrolytes, which will cause the battery's function to decline.
The study showed that when the battery is continuously operated at more than 45, its cycle life will be significantly reduced. This situation is more obvious during high-rate charging and discharging. Therefore, if working in a high temperature environment for a long time, the life of the power battery will be significantly shortened, its function will also be greatly reduced, and even cause safety accidents. Similarly, if the temperature is too low, the activity of the active materials inside the battery will obviously decrease, and the internal group and polarization voltage will increase, and the charging and discharging power and capacity will obviously decrease, and even cause the irreversible decline of battery capacity, and buried safety hazards. The Energy storage connector manufacturer tells you that, especially during the charging process, under the effect of the electric field applied to the charging device, lithium ions escape from the positive electrode into the electrolyte and move to the negative electrode, sequentially entering the negative electrode made of graphite, and form LiC compound.
In addition, the long-term uneven distribution of the temperature field inside the battery box will also cause the imbalance of the functions of the battery modules and cells, especially the aging rate of the batteries distributed in the high temperature area will be significantly faster than the low temperature part, and the accumulation of different batteries will follow. The difference in physical properties between the two will become more obvious, and then the consistency between the batteries will become worse, and even premature failure will occur, which shortens the life of the entire power battery system.
The connector is a necessary component for series and parallel connections between battery packs. The Energy storage connector manufacturer tells you that 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, it exceeds the battery pack’s temperature. Temperature, temperature will be transmitted to the inside of the battery, and then affect the stability of the battery, so it is a necessary condition for the connector to reach the characteristics of low temperature rise. The special connector for energy storage uses the terminal technology of the company’s independent intellectual property rights. The contact surface between the inside of the terminal and the pin is kept in the best area, which can effectively reduce the contact resistance, reduce the overcurrent density, and reduce the current temperature rise. At the same time, the new appearance design has planned multiple appearances into corrugated sectors to improve Heat dissipation function.
In addition, imported high-purity copper is selected as the metal material, which has high conductivity and stable overcurrent temperature rise. The plastic material uses unique alloy materials to mobilize a variety of plastic characteristics, both high strength and high toughness, and meets the requirements of fire protection. It has a higher thermal conductivity and speeds up heat dissipation. The Energy storage connector manufacturer tells you to use FIRST patented technology in the connection of internal terminals and wire noses to ensure the reliability of the connection between the two, increase the contact area, and increase the temperature of overcurrent At the same time, the stable and robust multi-point crimping process effectively reduces the temperature rise of the connection between the wire nose and the wire, and ensures the consistency of the temperature rise. The company's current temperature rise test results of connectors of different current levels can be controlled below 35 degrees Celsius (ambient temperature 20 degrees Celsius).
