Description

IoT-based bollard electric car charging device {Bollard type Electric car charging apparatus}

The present invention relates to a charging device for charging electric vehicles. More specifically, it relates to a bollard-integrated electric vehicle charging device that is implemented integrally with a bollard and can be installed on parking lot floors, road floors, etc., thereby eliminating restrictions on installation space. It's about.

Recently, as environmental issues have grown and technological advancements have occurred, the demand for electric vehicles that do not emit any exhaust gases is rapidly increasing, and it is certain that they will replace internal combustion engines within a few years. Electric vehicles drive by having an electric motor roll the wheels using power supplied from a battery, and the driving distance of an electric vehicle increases depending on the charging capacity of the battery.

Meanwhile, in order to increase the charging capacity of the battery, the size of the battery must be increased, but there were limitations in embedding a large battery in the limited space of an electric vehicle. Moreover, if the battery size is increased, the weight of the electric vehicle increases, so the driving distance does not increase significantly. It won't happen. For this reason, the reality is that the driving range of electric vehicles is shorter than that of conventional internal combustion engine vehicles, and therefore electricity must be charged frequently.

Electric vehicle chargers are roughly divided into fast chargers that supply hundreds of Kw or more of power, and slow chargers that supply 2 to 10 Kw of power.

Because fast chargers require a built-in transformer or high-power electrical equipment, they are expensive and large in size, require complicated power line construction, and have very strict licensing requirements. Accordingly, fast chargers can only be installed in parking lots of large buildings such as highway rest areas or department stores, and as a result, they are not installed in many cases in reality.
