Taking the permanent magnet DC motor as the research object, the design of the regenerative braking main circuit of the trackless rubber-coated electric vehicle in coal mine was carried out. The complete regenerative braking mathematical model was established by using the two-quadrant DC-DC chopper as the structure The simulation research on battery charge current and motor armature current during regenerative braking is carried out. The simulation results show that regenerative braking can produce large motor armature current and battery charge current, which can recover energy and improve the tracklessness of mine track Rubber wheel electric car driving range.
