    • Embodiments of the present disclosure relate to a control device and method for a contactor. The control device comprises a first high-side control unit, a second high-side control unit, a first low-side control unit and a second low-side control unit. The first high-side control unit and the second high-side control unit respectively connect a first magnetic unit and a second magnetic unit of the contactor to a power supply. The first low-side control unit is connected between the first magnetic unit and a reference voltage node, and the second low-side control unit is connected between the second magnetic unit and the reference voltage node. The control device further comprises a freewheel unit connected to the first magnetic unit and the second magnetic unit. The control device further comprises a controller. The controller is used to control operations of the control units so that in a state that at least one magnetic unit of the first magnetic unit and the second magnetic unit is disconnected from the power supply, a current of the at least one magnetic unit flows through the freewheel unit. According to embodiments of the present disclosure, the contactor may be made more energy-saving, and the operation cost may be reduced.
