The use of nickel-metal hydride batteries in tactical radios will lead to problems such as heavier loads, shorter battery life, and less intelligent power supply systems. Because analyzing the power supply guarantee requirements of tactical radio stations, this paper firstly models and simulates lithium-ion batteries to accurately estimate key design parameters such as lithium-ion power and balance control. Then, high-efficiency integration technologies of new materials such as PAA and LiPF6 are used to develop lithium-ion batteries with high specific energy density, good high and low-temperature performance, and lightweight. At the same time, DSP technology is used to develop battery fast charging and intelligent management software and hardware systems to achieve fast and real-time detection of battery state of charge, health state, and functional state. The battery-intelligent power supply system will provide theoretical guidance and technical support for the overall improvement of the combat effectiveness of tactical radio equipment.
