The present invention relates to an IoT-based commercial power charging device for electric vehicles. More specifically, the user connects a commercial power charging device for electric vehicles to power outlets installed in apartments, houses, public places, public buildings, etc. based on IoT. When charging an electric vehicle, power is connected between the power outlet and the electric vehicle in the commercial power charging device for an electric vehicle through the device authentication results of the power outlet and the commercial power charging device for the electric vehicle performed by the charging management server. It relates to an IoT-based commercial power charging device for electric vehicles that first charges the electric vehicle and charges the user for the cost of charging the electric vehicle later.

EV (Electric Vehicle) is a transportation device that runs on electricity and includes electric cars, electric motorcycles, electric bicycles, electric kickboards, etc., and is being developed and distributed around the world in response to environmental pollution caused by exhaust gases and energy saving trends. This is gradually spreading.

In the use of the above EV, an essential condition directly related to the performance and efficiency of use of the EV is the battery. This is because the maximum output of the motor is determined along with the driving distance of the EV depending on the capacity or maximum voltage of the battery.

However, since the number of charging stations that charge vehicle batteries used in electric vehicles is absolutely insufficient, it is necessary for drivers to identify charging stations located within their living radius in advance and avoid situations where battery power is insufficient through periodic charging.

Accordingly, if electric vehicles can be charged at places equipped with power outlets that can supply commercial power anytime, anywhere, in addition to charging stations provided in specific locations, not only will the spread of electric vehicles increase explosively, but driver convenience will also be greatly improved. It can rise.

Meanwhile, the driver of an electric vehicle pays a charging fee in advance to charge the electric vehicle, and performs charging for the amount paid. In the case of this method of paying charging costs in advance, if the driver did not have cash or the means to pay, there would be no way to charge the battery even if it was discharged while driving the electric vehicle, and if something unexpected happened during the charging process, it would be necessary to drive the electric vehicle. Even in those cases, there was a problem of not being able to recharge the amount paid in advance. In other words, when charging an electric vehicle, it is necessary for the user to pay for the amount of electricity charged, but postpaid payment has not yet been introduced.

Therefore, in the present invention, when a user charges an electric vehicle by connecting a commercial power charging device for an electric vehicle to a power outlet installed in various places such as an apartment, a shopping mall, or a public building, the power outlet and the commercial power supply for the electric vehicle are charged.
