Electric propulsion vehicle charging cable and power adapter attached to electric propulsion vehicle charging cable

An electric propulsion vehicle charging cable having one end provided with a power plug connected to a power source of a charging facility and the other end provided with a charging coupler detachably connected via a controller to an electric propulsion vehicle,

• wherein the power plug has an electrode structure including three high-voltage electrodes and a high-voltage ground pin, the electric propulsion vehicle charging cable used for charging a battery of the electric propulsion vehicle by using two of the three high-voltage electrodes,
• wherein the electric propulsion vehicle charging cable has a power adapter including electrode receptacles to which the three high-voltage electrodes and the high-voltage ground pin are connected and connection terminals having an electrode structure corresponding to a power source of a different standard from the electrode structure of the power plug,
• wherein the connection terminals of the power adapter have an electrode structure including two low-voltage electrodes and a low-voltage ground pin of a different standard from the electrode structure of the power plug, and
• wherein in the power adapter, the electrode receptacle to be connected to one high-voltage electrode not used as a charging electrode among the three high-voltage electrodes of the power plug and the electrode receptacle to be connected to the high-voltage ground pin are electrically connected to each other.
