In order to further study the underground charging safety of power batteries for coal mine robots, this paper proposes to study the energy transfer mechanism of power batteries in confined space and the difference of energy distribution in flammable and explosive special gas environment. On the basis of theoretical research, the safety performance of the temporary flameproof chamber formed during the underground charging process of the robot is verified by constructing the detection experimental platform of the explosion-proof automatic charging device of the robot, so as to solve the problem of potential safety hazard assessment caused by exposed contacts or unreliable docking during the underground charging process of the coal mine robot, and provide theoretical and experimental basis for the underground charging safety.
