Abstract: An electric vehicle charging system includes a connector plug connectable to a connector base connected to a modular charging unit. The connector plug includes a plurality of connectors receivable in a plurality of openings of the connector base. A connector of the plurality of connectors includes an extending portion for contacting a terminal connector of the connector base. The connector plug and the connector base are rotatable relative to each other after the plurality of connectors are received in the plurality of openings such that the extending portion rotates to contact the terminal connector to provide an electrical connection between the modular charging unit and a load of an electric vehicle. The connector plug and the connector base are lockable relative to each other to inhibit movement therebetween after the extending portion contacts the terminal connector.
