[0002] Due to the problems of high fuel consumption, high noise, and high pollution in coal mine auxiliary transportation equipment such as explosion-proof diesel engine trackless rubber-tyred vehicles and monorail locomotives, various companies and research units are actively developing and promoting the use of explosion-proof lithium-ion batteries and nickel-metal hydride batteries. New energy vehicles, but the matching explosion-proof charging device is in the initial stage. At present, the existing coal mine explosion-proof charging device has a charging gun for a single set of explosion-proof charging device, and the control adopts the explosion-proof control display panel + function operation button mode. It is possible to charge one explosion-proof new energy vehicle at a slow speed within a period of time. The existing problems and shortcomings are: First, because one set of explosion-proof charging device can only charge one explosion-proof new energy vehicle within one period of time. The implementation of slow charging cannot meet the needs of multiple explosion-proof new energy vehicles charging at the same time. However, there are many explosion-proof new energy vehicles in coal mines. In order to meet the charging demand, it is necessary to deploy a large number of explosion-proof charging devices, which makes the input cost of coal mine charging facilities high. At the same time, because it can only achieve slow charging, it cannot effectively meet the needs of fast charging for explosion-proof new energy vehicles with time limits; second, there is no corresponding authority system for operation, and there are potential safety hazards in use; third, human-computer interaction is inconvenient; fourth , the intelligence is not enough, and it cannot be integrated into the existing coal mine explosion-proof vehicle wireless communication dispatching management platform, which is not conducive to the effective management of the charging device; Fifth, the existing explosion-proof charging gun is equipped with 3 mutually independent connecting cables, 2 of which are used for The DC power supply is positive and the DC power supply is negative; the other one is used to transmit the low-voltage auxiliary power supply, charging communication, and charging connection confirmation signal, which is very inconvenient when carrying the gun to hand over the power
