Driver-selectable electric vehicle charger information system based on state of charge}

The present invention relates to an electric vehicle charger guidance system, and more particularly, to a driver-customized electric car charger guidance system that guides the optimum charger that meets the type of service selected by the driver according to the driver's propensity or driving situation based on state of charge information. it's about

A vehicle drives by driving a power load such as an engine with energy generated when fossil fuels such as gasoline, diesel, or gas are burned. Recently, as the problem of depletion of fossil fuels and air pollution due to excessive use have become serious, research and development on the use of renewable energy and eco-friendly transportation are being actively conducted.

Among eco-friendly means of transportation, electric vehicles do not emit air pollutants at all and do not cause noise pollution during operation, so automobile manufacturers around the world are scrambling to launch them into the electric vehicle market. In addition, countries around the world are making efforts to develop and install electric vehicle charging systems for the spread and smooth use of these eco-friendly electric vehicles.

A battery that provides the most important power to an electric vehicle has to supply relatively less energy than a conventional internal combustion engine vehicle, making it difficult for an electric vehicle to be activated due to a relatively short mileage. To this end, the capacity of the battery can be increased, but due to the nature of the battery, there are limits to the size and capacity of the battery that can be mounted on an electric vehicle. A charger guidance system is required.

However, the current charging station or charger guidance system has a problem in that the charging information provided to the driver is limited, and the driver has to select a charging station based on reasonable judgment on distance and cost. For example, the navigation device guides the nearest charging station or a charging station in a certain area around the vehicle based on the driving distance, and the driver selects and visits a specific charging station or charging station among them. In this case, since the same charging station or charger is guided not only to a specific driver but also to all other drivers, charging waiting time occurs even when a specific charging station or charger is visited.

In addition, the driver may have very diverse charging conditions, such as conditions in which charging can be completed in the shortest time, conditions in which charging can be completed at the lowest cost regardless of time or distance, and even for the same driver on the same day. Depending on the driving conditions of the above charging requirements may vary. That is, the driver may request the charger guidance service under various conditions different from each other according to circumstances.

However, conventional charging stations or charger guidance systems (hereinafter, referred to as 'charger guidance systems') do not guide chargers according to these types of various situations, and have limitations in providing only locations and charging prices unilaterally.
