摘要： An exemplary system for controlling electrodeposition coating for electrochemically forming a coating film on a coating object in an electrodeposition tank storing electrodeposition solution includes, a positive electrode configured to apply a positive electrode voltage to a positive electrode disposed in the electrodeposition tank, a negative electrode configured to apply a negative electrode voltage to the coating object transferred by a hanger, and an electrodeposition controller configured to electrochemically deposit the coating film on an external surface and an internal surface of the coating object by applying the positive electrode voltage to the positive electrode and the negative electrode voltage to the negative electrode, where the electrodeposition controller may be configured to control voltage, current, and pulse in multi-stages over time from a dip-in time point to a draw-out time point of the coating object into and from the electrodeposition tank.
