Description
technical field [0001] The invention relates to a mining electric wheel dump truck, in particular to a low-voltage power supply device for a mining electric wheel dump truck. Background technique [0002] The low-voltage power supply of the mining electric wheel dump truck is powered by two sets of batteries. The starting battery set is used to start the main engine starter motor and the pre-fuel pump motor. The control battery set provides regulated power for the vehicle control system and other low-voltage components of the truck. At present, the two sets of batteries on the truck are scattered in space due to their respective functions. The wiring connections between the two are numerous and messy, and the protection measures such as overheating, overcurrent, and voltage stabilization are not complete enough, which affects the overall appearance of the truck and reduces the This improves the stability of the truck's low-voltage circuit and increases the maintenance freque...
