1. Battery performance parameters
Capacity: Customized ultra-low temperature lithium batteries should have a high enough energy density to ensure stable power output under extreme conditions to meet the long-term operation needs of military equipment.
Voltage: The output voltage of the battery must meet the power supply requirements of military equipment to ensure the normal operation of the equipment and avoid performance degradation or damage caused by an excessively high or low voltage.
Internal resistance: The internal resistance of the battery should be as low as possible to reduce energy loss and improve the efficiency of the battery.
Self-discharge rate: The self-discharge rate of the battery during storage should be controlled at a low level to extend the service life of the battery.
Two, ultra-low temperature working environment
Operating temperature range: The battery should work normally in an ultra-low temperature environment of -60 ° C to -40 ° C, without performance degradation or failure.
Low temperature discharge performance: in the ultra-low temperature environment, the battery should have good discharge performance to ensure the normal operation of the equipment.
