Summary:A method for preventing an inrush current of an electric vehicle charger may include the steps of determining whether there is a need for an increase or decrease in a charging current level while currently supplied to an electric vehicle to be charged; decreasing the charging current level at a predetermined ratio when it is determined that there is the need for the increase or decrease in the charging current level; checking whether an inrush current occurs for a first time; activating or deactivating at least one charging module to increase or decrease the charging current level according to the request of the electric vehicle to be charged, when the inrush current does not occur for the first time; checking whether the inrush current occurs for a second time; and increasing the charging current level by the charging current level requested by the electric vehicle to be charged, when the inrush current does not occur for the second time.
