Solution of Starting Voltage Drop for Mining Truck with Electric Wheel

  • For problem that control system of mining truck with electric wheel cannot restart after the engine started caused by voltage drop of battery pack, the paper analyzed voltage changes of battery pack in the process of engine starting, and proposed two solutions: increase batteries for separate power supply of the control system, and modify the control circuit. It analyzed advantages and disadvantages of the two solutions and figured the second option is better. The results of plant commissioning and industrial experiments show that the second option is superior. Presently the mining truck with electric wheel adopting the second solution has been successfully operating for 4 000 h, which ensures success rate of start-up of the engine control system is 100%, and starting process is safe and reliable.
