Start power control system for heavy equipment

The utility model relates to a start power especially relates to a start power control system for heavy equipment. The utility model discloses a start power control system for heavy equipment is proposed, through setting up MOS switch and treater control charging loops and discharging the the direction of current flow in return circuit, connect the treater in parallel in the return circuit of discharging, the group supplies power by the dc -battery, need not independent power and supplies power for the controller. The controller includes two MOS switches, treater, voltage collector, temperature data collection ware, the break -make of two MOS switches is connected and controls to treater and voltage collector, temperature data collection ware, and one of them MOS switch is established tiesin charging loops, and unidirectional flux makes the electric current flow in limiting current to flow, and another MOS switch is established ties in the return circuit of discharging, and unidirectional flux limiting curren
