The utility model discloses a charging system and a charging station for an electric automobile. The charging system comprises N direct-current charging devices, and each of the N direct-current charging devices comprises an AC/DC converter and a direct-current output-end interface device disposed in the AC/DC converter. The interface device is used for connecting with a direct-current charging interface of the electric automobile. The charging system also comprises a PCS (power conversion system), and a battery pack which is connected with the PCS. The charging system also comprises connecting devices which are connected among an alternating-current power supply, the N direct-current charging devices, and the PCS. When the connecting devices are located in a first state, the N direct-current charging devices and the PCS are respectively connected with the alternating-current power supply. When the connecting devices are located in a second state, M of the N direct-current charging devices are respectively connected with the PCS, wherein M is less than N. The charging system provided by the utility model solves a technical problem that a conventional charging system for the electric automobile does not have a function of emergency charging.
