The invention provides a charging and power supplying device and method for an electric vehicle, the charging and power supplying device for the electric vehicle comprises a first charging port, a second charging port, a main positive relay and a main negative relay, the main positive relay and the main negative relay are electrically connected with the first charging port and a battery pack of the electric vehicle, and the main negative relay is electrically connected with the second charging port. The main positive relay, the main negative relay, the first charging port and a battery pack of the electric vehicle form a first charging loop, and when the first charging port is connected with an external power supply, the main positive relay and the main negative relay are closed so as to charge the battery pack of the electric vehicle through the first charging port; and the main positive relay, the second charging port and the battery pack of the electric vehicle form a second charging loop, and when the second charging port is connected with the external power supply, the main positive relay and the main negative relay are closed so as to charge the battery pack of the electric vehicle based on the second charging port. The charger can be compatible with two charging modes of fast charging and slow charging, and has the advantages of being small in part change and low in cost.
