[0029] Hereinafter, the first embodiment will be described.
[0030] [the whole frame]
[0031] figure 1 It is a diagram showing an example of the configuration and usage environment of a V2G (Vehicle to Grid) system 1 including the management device 100 of the first embodiment. like figure 1 As shown, the V2G system 1 includes a management device 100 , a plurality of charging and discharging devices 200 , 200 - 1 , 200 - 2 , 200 - 3 , a vehicle 10 and a power system 400 . exist figure 1 200, 200-1, 200-2, and 200-3, but when not distinguishing them, they are described as charge and discharge device 200.
[0032] The management device 100 controls charging and discharging between the battery 40 mounted on the vehicle 10 and storing electric power for running the vehicle 10 , and the electric power system 400 . The electric power system 400 includes, for example, a power station, a power transformation facility, a power transmission line, a power distribution facility, a t...
no. 2 approach
[0081] Hereinafter, a second embodiment will be described. The second embodiment differs from the first embodiment in the method of setting the lower limit value of the SOC during V2G. The following description will focus on this difference.
[0082]When the position of vehicle 10 matches the first specific point, management unit 130 sets a fourth specific point different from the first specific point, and calculates the SOC of battery 40 at which vehicle 10 can travel to the fourth specific point. The first specific point is, for example, the home of the user of the vehicle 10 , and the fourth specific point is, for example, a facility to be visited registered in the user's schedule information. When the position of the vehicle 10 coincides with the first specific point, the management unit 130 subtracts the SOC of the battery 40 that enables the vehicle 10 to travel from the position of the vehicle 10 to the fourth specific point from the SOC of the battery 40 . The value ...
no. 3 approach
[0091] Hereinafter, a third embodiment will be described. The third embodiment differs from the first embodiment in that the management device is mounted on a vehicle. The following description will focus on this difference.
[0092] Figure 11 It is a configuration diagram of a vehicle 10A according to the third embodiment. like Figure 11 As shown, the vehicle 10A includes, for example, a motor 12, a drive wheel 14, a braking device 16, a vehicle sensor 20, a PCU (Power Control Unit) 30, a battery 40, a battery sensor 42 such as a voltage sensor, a current sensor, and a temperature sensor, a navigation device 50, A communication device 60 , a display device 70 , a charging port 80 and a converter 82 .
[0093] The control unit 36A includes, for example, an acquisition unit 36α and a management unit 36β. Each component of the control unit 36A is realized by, for example, a hardware processor such as a CPU executing a program (software). Part or all of these constituent ...
