Original Abstract Submitted
An embodiment method of controlling a bidirectional charging system includes operating a power supply mode to supply alternating current (AC) power to an external device connected to a vehicle, performing real-time current control to limit output current to a preset first current level or less during the power supply mode, determining that the real-time current control is not possible, in response to determining that the real-time current control is not possible, suspending the power supply mode temporarily, and resuming the power supply mode from a zero-crossing point of the AC power existing within a preset reference time from a time point at which the power supply mode is temporarily suspended.
