Description

  The present invention relates to an electric vehicle charging apparatus, an electric vehicle charging system, an electric vehicle charging method, a program, and a recording medium that supply electric power for charging an electric vehicle battery, for example, at a charging station.

  In recent years, an electric vehicle using a motor as a power source instead of an internal combustion engine has been developed. An electric vehicle uses a battery as a power source, and travels by driving a motor by supplying power from the battery. For this reason, compared with an internal combustion engine, it has many advantages such as low energy cost, high energy efficiency, extremely low noise, and no exhaust gas when traveling. On the other hand, there are many problems to be solved in the future, such as expensive batteries, shorter travel distance per weight than internal combustion engines, and longer charging time.

  On the other hand, regardless of whether an electric vehicle or a gasoline vehicle is used, a system for presenting information to the user of the vehicle has been proposed in consideration of convenience when driving the vehicle. For example, in the navigation system disclosed in Patent Document 1, when it is not possible to travel to the second gas station on the set travel route by detecting the remaining energy of the vehicle and the travel position, It is designed to guide the refueling at the closest one of the previous gas station and the gas station that deviates from the travel route.

  However, a system for notifying the user of the scheduled completion of charging the battery of the automobile has not been developed yet. For this reason, the user is forced to be inconvenient because he / she does not know the completion time for charging the battery of the car and cannot set the scheduled departure time, or is likely to have a wasteful waiting time at the charging station.

  Next, a case where the required power amount is calculated based on the information for calculating the required power amount acquired from the vehicle side system 2 will be described.

(3a) When calculating the required electric energy based on the information for calculating the required electric energy acquired from the automobile-side system 2 The electric energy calculator 13 determines the remaining mileage from the mileage calculator 35 of the automobile-side system 2 The information is acquired, the power consumption rate information of the electric vehicle 101 is acquired from the power consumption rate calculation unit 22, and the remaining battery level information is acquired from the remaining battery level measurement unit 23.

It is good also as a structure by which is selected naturally.

Here, it is as follows when the example (for example, Mitsubishi I-MIEV) of normal charge in the case of performing full charge from an empty state with respect to the storage battery 26, and quick charge is shown. ,
In the case of normal charging, power supply: AC200V (15A), time required: about 7 hours (full charge)
Power supply: AC100V (15A), time required: Approximately 14 hours (full charge)
In the case of fast charging, power supply: three-phase 200V (50KW), required time: about 30 minutes (80% charging)
In the case of rapid charging for the purpose of short-time charging, due to the characteristics of the storage battery 26, charging time becomes longer as it approaches full charging, so charging is completed with 80% charging for 30 minutes. Further, in the storage battery 26 of the above example, it is considered that the travelable distance is about 160 km (running in a constant environment) due to full charge, and actually about 90 km (when using an air conditioner or the like) depending on the usage environment.

Therefore, when charging the example of the storage battery 26 (Mitsubishi I-MIEV), the required time is about 60 minutes (80% charge) at three-phase 200 V (25 KW).

  In addition, when charging of the first electric vehicle 101 was started at 50 KW and the required time of 30 minutes at the charging station with two charging devices installed, rapid charging was also selected for the second electric vehicle 101 to be charged thereafter. In this case, the required time is the time until the first unit is completed plus 30 minutes.
