1. An electric vehicle charger and energy storage system mounted transformer, comprising:
an energy storage system which stores electricity generated from a transformer; and
an electric vehicle charging device connected to the transformer or the energy storage system and charging the electric vehicle with electricity supplied from the transformer or the energy storage system, wherein the energy storage system and the electric vehicle charging device are composed of one integrated module and connected to the transformer;
further comprising: an auxiliary electricity supply device which connects or disconnects the transformer and the electric vehicle charging device, and is configured as an integrated module together with the energy storage system and the electric vehicle charging device, wherein the connection between the energy storage system and the electric vehicle charging device is cut off when connecting the transformer and the electric vehicle charging device; and
further comprising: a fault detector which detects whether the energy storage system is in a failure state, wherein the transformer and the electric vehicle charging device are connected to each other through the auxiliary electricity supply device when the energy storage system is determined to be in a failure state through the fault detector, and the connection between the energy storage system and the electric vehicle charging device is cut off.
