Embodiment Construction

[0016] Next, an exemplary embodiment of the present invention will be described in detail with reference to the drawings.

[0017] figure 1 It is a block diagram showing the configuration of the charging system 20 including the charging control device 10 according to the embodiment of the present invention. As shown in the figure, the charging system 20 includes a charging control device 10, a power supply unit 201, contactors 202, 203, and 204, and measurement units 205, 206, and 207.

[0018] The power supply unit 201 is connected to the electric vehicles 208, 209, and 210 via contactors 202, 203, and 204 composed of switches, so as to charge the electric vehicles 208, 209, and 210 by supplying power thereto. The measuring units 205, 206, and 207 are respectively associated with the contactors 202, 203, and 204, so as to measure the corresponding charging states of the electric vehicles 208, 209, and 210 connected to the contactors.

[0019] Possible methods of measuring the state...

Abstract

The present invention relates to a charge control device and a charge control method. A charging control device (10), which is used to control the charging of a plurality of electric vehicles (208, 209, 210), comprising: a charging determination unit (305), which determines ) whether the state of charge of the electric vehicle (208, 209, 210) connected to the charging determination unit satisfies a predetermined condition, and it determines to charge the electric vehicle satisfying the condition if the condition is satisfied, and it determines to interrupt charging of an electric vehicle that does not meet the conditions, and charges other electric vehicles; and a contactor control unit (302) that controls the contactors (202, 203, 204) based on the determination made by the charging determination unit (305) ) to control.

Description

Technical field [0001] The present invention relates to a charging control device, a charging control method and a program for electric vehicles. Background technique [0002] In recent years, electric vehicles (EV) have become increasingly popular, and it is therefore foreseeable that a large number of EVs may be charged with a limited number of chargers in the future. In this case, the simplest charging method is to repeatedly charge one EV each time, terminate the charging when the EV is fully charged or charged to the predetermined termination charging capacity, and then start charging the next EV Charging, etc. However, with this method, the EV that entered the charging queue later will not start charging until all the EVs that entered the charging queue earlier have been fully charged, so the EV must wait a long time. [0003] Patent Document 1 discloses a vehicle power supply system including a plurality of batteries and a generator that generates electric energy for charg...
