Abstract: A direct current charging apparatus, a powertrain, and an electric vehicle. The direct current charging apparatus which includes a direct current charging interface, a switch module, and a direct current voltage conversion module is configured to charge power battery of the electric vehicle. The direct current charging interface is configured to connect a positive electrode and a negative electrode of a power supply apparatus and a positive electrode and a negative electrode of the power battery to form a charging loop. The switch module is configured to connect or disconnect the charging loop. The direct current voltage conversion module is configured to output a preset direct current voltage to the positive electrode and the negative electrode of the power supply apparatus. When the charging loop between the power battery and a charging pile is connected again, charging can be resumed without re-swiping card/re-scanning QR code.
