The signal communication circuit 82 is configured to communicate information (for example, power supply information on a power supply voltage and a power supply current for charging the battery 84 as described below) with the signal communication circuit 12 of the power supply device 1 . The battery 84 stores the DC power supplied by the power supply device 1 (DC 300 [V] in this embodiment). The charging control circuit 81 controls the charging circuit 83 based on the above information input from the signal communication circuit 82 .
在本实施例的供电系统中，从电动车辆C侧发送与用于对电池84进行充电的供电电压和供电电流有关的供电信息，然后在供电装置1侧，信号通信电路12获取该供电信息。此外，在供电装置1中，将信号通信电路12所获取的供电信息输入至电源控制电路11，然后电源控制电路11将该供电信息与从控制装置3发送来的DC配电板2的供电能力信息进行比较，并且设置供给至电动车辆C的供电电压和供电电流。电源控制电路11基于所设置的供电电压和所设置的供电电流来对DC/DC转换器13进行控制，以将期望的DC电力供给至电动车辆C。例如，在从电动车辆C侧向供电装置1要求DC 300[V]和20[A]并且DC配电板2的供电能力为3000[VA]的情况下，供电装置1向电动车辆C供给DC300[V]和10[A]。在本实施例中，信号通信电路12对应于供电信息获取部，并且电源控制电路11对应于控制部。In the power supply system of this embodiment, power supply information on the power supply voltage and power supply current for charging the battery 84 is transmitted from the electric vehicle C side, and then on the power supply device 1 side, the signal communication circuit 12 acquires the power supply information. In addition, in the power supply device 1, the power supply information acquired by the signal communication circuit 12 is input to the power supply control circuit 11, and then the power supply control circuit 11 compares the power supply information with the power supply capability of the DC distribution board 2 sent from the control device 3 The information is compared and the supply voltage and supply current supplied to the electric vehicle C are set. The power supply control circuit 11 controls the DC/DC converter 13 to supply desired DC power to the electric vehicle C based on the set supply voltage and the set supply current.

此外，本实施例的供电系统符合SAE(车辆工程师协会)(注册商标)标准，并且供电装置1的电源控制电路11向电动车辆C的充电控制电路81输出SAE信号(充电许可信号)。该SAE信号是用于限制对电池84进行充电时的充电电流的信号。然后，电动车辆C的充电电路83将该充电电流限制为由该SAE信号的占空比所确定的电流值。Furthermore, the power supply system of the present embodiment conforms to the SAE (Society of Automotive Engineers) (registered trademark) standard, and the power supply control circuit 11 of the power supply device 1 outputs an SAE signal (charging permission signal) to the charging control circuit 81 of the electric vehicle C. This SAE signal is a signal for limiting the charging current when charging the battery 84 . Then, the charging circuit 83 of the electric vehicle C limits the charging current to a current value determined by the duty ratio of the SAE signal.
接着，以下说明供电系统的操作。当供电装置1的供电用连接器15与电动车辆C的车辆侧连接器85相连接时，将供电信息从电动车辆C发送至供电装置1，并且还将D C配电板2的供电能力信息从控制装置3发送至供电装置1。供电装置1接收供电信息以及DC配电板2的供电能力信息，并且在电源控制电路11中将该供电信息与该供电能力信息进行比较。然后，供给的DC电力(供电电压和供电电流)以保持在DC配电板2的供电能力范围内的方式进行确定。然后，电源控制电路11对DC/DC转换器13进行控制，以将所确定的供电电压和供电电流的DC电力供给至电动车辆C。然后，电源控制电路11还将上述SAE信号发送至电动车辆C。Next, the operation of the power supply system will be described below. When the power supply connector 15 of the power supply device 1 is connected to the vehicle-side connector 85 of the electric vehicle C, the power supply information is sent from the electric vehicle C to the power supply device 1, and the power supply capability information of the DC distribution board 2 is also transmitted. It is sent from the control device 3 to the power supply device 1 . The power supply device 1 receives the power supply information and the power supply capability information of the DC distribution board 2 , and compares the power supply information with the power supply capability information in the power supply control circuit 11 . Then, the supplied DC power (supply voltage and supply current) is determined in such a manner as to remain within the range of the power supply capability of the DC distribution board 2 . Then, the power supply control circuit 11 controls the DC/DC converter 13 to supply the electric vehicle C with DC power of the determined supply voltage and supply current. Then, the power supply control circuit 11 also sends the above-mentioned SAE signal to the electric vehicle C.
另一方面，在电动车辆C中，供给了上述DC电力并且发送来上述SAE信号，然后充电控制电路81对充电电路83进行控制从而以如下充电电流对电池84进行充电，其中该充电电流小于或等于由该SAE信号的占空比所确定的电流值。然后，当充电完成时，该系统例如通过在控制面板4的画面上显示充电完成来通知用户。然后，当用户通过该画面得知充电完成并将供电用连接器15从车辆侧连接器85移除时，一系列的供电操作完成。On the other hand, in the electric vehicle C, the above-mentioned DC power is supplied and the above-mentioned SAE signal is transmitted, and then the charging control circuit 81 controls the charging circuit 83 to charge the battery 84 with a charging current less than or equal to the current value determined by the duty cycle of the SAE signal. Then, when charging is completed, the system notifies the user, for example, by displaying charging completion on the screen of the control panel 4 . Then, when the user knows the completion of charging through the screen and removes the power supply connector 15 from the vehicle side connector 85, a series of power supply operations is completed.
如上所述，在本实施例中，可以实现使用住宅H内进行配电得到的DC电源作为充电电源的供电装置1。然后，电动车辆C侧无需设置传统的AC/DC转换器。因此，与上述传统示例相比，供电装置1可以防止电动车辆C侧的电力转换损耗。另外，由于设备(在本实施例中为电动车辆C)的供电信息被发送至供电装置1，因此供电装置1还可以供给与所连接设备相对应的DC电力。As described above, in the present embodiment, it is possible to realize the power supply device 1 using the DC power source obtained by power distribution in the house H as a charging power source. Then, there is no need to install a conventional AC/DC converter on the C side of the electric vehicle. Therefore, the power supply device 1 can prevent power conversion loss on the side of the electric vehicle C, compared to the above-described conventional example. In addition, since the power supply information of the equipment (electric vehicle C in this embodiment) is transmitted to the power supply apparatus 1, the power supply apparatus 1 can also supply DC power corresponding to the connected equipment.
此外，在本实施例中，由于从供电装置1发送来的SAE信号(充电许可信号)，供电装置1可以设置与所连接设备(在本实施例中为电动车辆C)相对应的充电电流。在设备侧，充电电流被限制为所设置的电流值。因此，供电装置1可以防止由于过电流而发生停电。Furthermore, in this embodiment, due to the SAE signal (charging permission signal) sent from the power supply device 1, the power supply device 1 can set the charging current corresponding to the connected device (electric vehicle C in this embodiment). On the device side, the charging current is limited to the set current value. Therefore, the power supply device 1 can prevent a power failure due to an overcurrent.
另外，供电系统基于从电动车辆C侧发送来的供电信息以及从控制装置3发送来的DC配电板2的供电能力信息来设置供给至电动车辆C的供给电力。因此，DC电力决不会超过DC配电板2的供电能力。此外，供电系统可以供给与电动车辆C所需的电力更接近的D C电力。In addition, the power supply system sets the power supply to the electric vehicle C based on the power supply information sent from the electric vehicle C side and the power supply capability information of the DC distribution board 2 sent from the control device 3 . Therefore, the DC power never exceeds the power supply capability of the DC distribution board 2 . In addition, the power supply system can supply DC power closer to that required by the electric vehicle C.

如果电动车辆是与AC充电相兼容的电动车辆C2，则使切换器17切换至AC配电板5侧，并且向电动车辆C2供给AC电力。然后，该AC电力由配置于电动车辆C2内的AC/DC转换器(未示出)转换成预定的DC电力，并且充电电路83以该DC电力对电池84进行充电。If the electric vehicle is an electric vehicle C2 compatible with AC charging, the switcher 17 is switched to the AC distribution board 5 side, and AC power is supplied to the electric vehicle C2. Then, the AC power is converted into predetermined DC power by an AC/DC converter (not shown) disposed in the electric vehicle C2, and the charging circuit 83 charges the battery 84 with the DC power.
如果电动车辆是与AC/DC充电相兼容的电动车辆C3，则供电装置1所供给的电力可以是从AC配电板5或DC/DC转换器13所输出的。然而，考虑到与转换次数相关联的转换损耗，更优选利用DC/DC转换器13来供给DC电力。在这种情况下，电动车辆C3的操作与电动车辆C1的操作相同。If the electric vehicle is an electric vehicle C3 compatible with AC/DC charging, the electric power supplied by the power supply device 1 may be output from the AC distribution board 5 or the DC/DC converter 13 . However, DC power is more preferably supplied using the DC/DC converter 13 in consideration of conversion loss associated with the number of conversions. In this case, the operation of the electric vehicle C3 is the same as that of the electric vehicle C1.
如上所述，在本实施例中，由于切换器17的切换，可以选择从AC配电板5所输出的AC电力或从DC/DC转换器13所输出的DC电力，作为经由供电线L1供给至电动车辆C1~C3的电力。因此，可以提供便利的供电系统。As described above, in this embodiment, due to the switching of the switcher 17, the AC power output from the AC distribution board 5 or the DC power output from the DC/DC converter 13 can be selected as the power supply via the power supply line L1. Electric power to electric vehicles C1~C3. Therefore, a convenient power supply system can be provided.

Then, DC powers corresponding to the determined power supply ratios are supplied to the power supply devices 1 respectively. Other features and functions are the same as in Embodiments 1-3. Thus, the same reference numerals are assigned to the same constituent elements, and explanations for these constituent elements are omitted.
本实施例的供电系统包括供电装置1、DC配电板2、控制装置3、控制面板4和AC配电板5。The power supply system of this embodiment includes a power supply device 1 , a DC distribution board 2 , a control device 3 , a control panel 4 and an AC distribution board 5 .
