Lithium-battery-powered reluctance launcher is a device that utilizes lithium batteries to directly discharge into coils, generating electromagnetic force to accelerate an armature. Due to the strong sensitivity of lithium batteries to environment temperature, the launch characteristics of the lithium-battery-powered reluctance launcher also exhibit significant fluctuations with environmental temperature. To address this issue, the research was conducted. Firstly, a dynamic launch theoretical model of the reluctance launcher was established based on the Law of Energy Conservation to analyze the mechanism of temperature's impact on launch characteristics; Secondly, an experimental-simulation integrated modeling method was employed, where circuit parameter measurement experiments were carried out using a constant temperature chamber, and the test results were used as inputs for the simulation model to evaluate the influence characteristics of temperature on the launcher's performance; Finally, practical launch experiments were conducted to obtain the mapping relationship between temperature and launcher velocity. Research indicates that temperature exerts a nonlinear influence on the muzzle velocity and system efficiency of lithium-battery-powered reluctance launchers. When environment temperature ranges from 15 °C to 30 °C, both muzzle velocity and system efficiency exhibit minimal fluctuations while maintaining high performance levels. At temperatures dropping to -5 °C and -15 °C, muzzle velocity decreases to 70.77 % and 30.4 % of its peak value, with system efficiency reduced to 91 % and 41.1 % of its original level, respectively. The results show that temperature significantly influences the launching characteristics of lithium-battery-powered reluctance launcher. It would be better to find a solution to the issue of temperature influence on launching characteristics.
