Description

Bus duct device for electric vehicle charging This invention relates to a bus duct device for charging electric vehicles, and more specifically, to a bus duct device for charging electric vehicles that simplifies the installation structure of a charging station by installing a charging connector on the bus duct and integrating a cutoff part that blocks overcurrent and leakage current between the bus bar and the charging connector, and ensures stable supply of current from the bus bar to the contact part by designing the contact part to have cushioning power and maximize the contact area with the bus bar, and allows for determining aging of the bus bar due to prolonged outdoor exposure by measuring the impedance of a flange made of the same material as the bus bar. As environmental pollution, the increase in carbon dioxide, and global warming become serious issues, the demand for electric vehicles is increasing. These vehicles move by driving motors with electricity stored in batteries, rather than by burning fossil fuels to power engines. As the adoption of electric vehicles increases, the installation of charging stations for charging electric vehicles is also increasing. For reference, a technology that enables the easy connection and installation of multiple electric vehicle charging devices from a single power source by introducing a busbar, expanding it arbitrarily, and branching it to connect loads has been disclosed by the applicant in the "Busbar Device for Charging Electric Vehicles" of Korean Registered Patent Publication No. 10-2476593 (Date of publication December 12, 2022).
