Description

Electric vehicle charger {ELECTRIC VEHICLE CHARGING DEVICE}

The present invention relates to an electric vehicle charger, and more specifically, to an electric vehicle charger with a new structure that simplifies charger installation and reduces installation time and cost.

Electric vehicle chargers are classified into fast chargers and slow chargers. A fast charger is a method of charging by supplying direct current (DC) power directly from the charger to the battery. A slow charger is a method in which the charger supplies alternating current (AC) power, and the electric vehicle's OBC (On Board Charger) converts this power to direct current and charges the battery. It usually has a performance of 7kW and uses AC single-phase 5-pin. do.

In addition, electric vehicle chargers are made in various forms such as standing type, ceiling type, and stationary type to charge electric vehicles in designated places indoors or outdoors. Standing and ceiling types are mainly installed outdoors, while stationary types are mainly installed inside buildings. In the case of stationary types installed inside buildings, they are installed in various fixed structures on the walls inside the building.

Recently, the installation of slow chargers at home has been increasing as a home charger for electric vehicles. To install a charger, you can apply for electricity use at KEPCO and install the charger after approval. In other words, due to the risk of fire due to the load on the existing home's electrical capacity and progressive taxes, it is necessary to carry out electrical work to install electric vehicle meters and circuit breakers from KEPCO to the house after a safety inspection, and then install a charger through an electric installation company. do. At this time, the installation fee and travel fee are determined according to the installation time of the charger.

The existing electric vehicle charger installation method is a stationary type installed inside a building, and is installed in various fixed structures on the walls inside the building. For example, after drilling and installing the bracket into the wall, the charger body is fixed to the bracket.

However, the existing electric vehicle charger has a structure that requires opening the charger main cover and directly connecting the wiring, which has the disadvantage of lower workability and longer installation time. In addition, when the charger breaks down, it is difficult for the general public to inspect due to complicated electrical wiring, and there is the inconvenience of having to rely on a professional electrical installation contractor.

Therefore, a new structure of charger installation method was required to simplify charger installation, improve workability and reduce installation time.
