摘要： A control system that sets a voltage of a DC bus connected with a secondary battery to an optimal value in accordance with a capacity of a power supply and characteristics of the secondary battery to stabilize a battery voltage of the secondary battery. The control system includes: drive units having a crusher that crushes an object to be crushed; inverters connected to the respective drive units and convert power; a converter that receives power from an AC power supply and converts the received power into DC power; a lithium-ion battery that charges the DC power according to a drive state of the drive units or supplies power to the drive units according to the drive state of the drive units; and a PLC that sets a conversion voltage of the converter based on a state of the lithium-ion battery and an output capacity of the AC power supply.
