In order to meet the power demand of military equipment in extreme low temperature environments, customized ultra-low temperature lithium batteries need to meet a series of strict standard requirements, as follows:
1. Performance parameters
Batteries should have high energy density to ensure stable and continuous power output, meeting the needs of long-term operation. Its voltage must meet the power supply requirements of military equipment to avoid equipment performance degradation or damage. At the same time, the internal resistance of the battery should be as low as possible to reduce energy loss and improve efficiency. Controlling the self discharge rate at a lower level can extend the battery life.
2. Temperature environment
The battery should operate normally in an ultra-low temperature environment of -60 ℃ to -40 ℃, and have good discharge performance to ensure the normal operation of the equipment in extreme temperatures.
3. Security performance
Batteries must have anti impact and anti vibration capabilities, explosion-proof and other protective functions to adapt to the complex conditions of military environments and prevent explosion accidents under extreme conditions. At the same time, it should have functions such as short-circuit protection, overcharge and overdischarge protection, etc., to eliminate safety hazards such as overheating and fire.
4. Service life and reliability
Batteries need to have a long cycle life to adapt to long-term use of military equipment. Meanwhile, after rigorous testing and screening, the battery should have high reliability to ensure stable operation under extreme conditions.
5. Electromagnetic compatibility
The battery must comply with electromagnetic compatibility standards to ensure normal operation in an electromagnetic environment and not generate interference.
6. Environmental adaptability testing and quality assurance
The battery needs to undergo environmental adaptability testing, including testing in harsh environments such as temperature shock, humidity, salt spray, etc. Strict quality control should be implemented during the manufacturing process to ensure that each batch of products meets standard requirements and is certified by relevant authoritative organizations.
In summary, the customized standards for military ultra-low temperature lithium batteries cover multiple aspects such as battery performance, ultra-low temperature operation, safety performance, durability and reliability, electromagnetic compatibility, explosion and shock resistance, environmental adaptability testing, and quality assurance and certification. These standards aim to ensure that batteries provide stable and reliable power supply for military equipment in extreme environments, meeting the special needs of military applications.
