通信装置37例如在电池11的充电开始时、充电过程中、充电结束时、从电池11向电子设备60的放电开始时、放电过程中、放电结束时等，与外部设备之间进行通信，通知电池11的充放电的状态。
车灯单元36例如在电池11的充电开始时、充电过程中、充电结束时、从电池11向电子设备60的放电开始时、放电过程中、放电结束时等，通过使设置在车内或者车外的适当位置的车灯亮灯，向乘员通知电池11的充放电的状态。
扬声器单元35例如在电池11的充电开始时、充电过程中、充电结束时、从电池11向电子设备60的放电开始时、放电过程中、放电结束时等，通过使设置在车内或者车外的适当位置的扬声器发出警报音，向乘员通知电池11的充放电的状态。
车辆电源开关32是用于对车辆系统100的启动、停止进行切换的按钮式开关。
外部输出开关33是按钮式开关，能够通过操作该外部输出开关33，对是否从插座22输出电力进行切换。在将外部输出开关33接通的情况下，从DC/AC逆变器21输出交流电力，在将外部输出开关33断开的情况下，不从DC/AC逆变器21输出交流电力。
I/F装置34是用于设定各种显示器的显示方式的接口，例如，能够根据使用者的需求而变更充放电的标记(符号)的显示方式。
车辆系统100还具有：第2充电端口44，其与快速充电用的电力供给装置90连接；以及继电器42，其对该第2充电端口44与电池组10之间的连接、断开进行切换。在充电时间不富裕的情况下，能够在将继电器42接通的状态下，将由第2充电端口44供给的电力充电至电池11。
充电电缆70具有：电源插头73，其用于与外部电源80连接；控制盒72；以及充电插头71，其用于与第1充电端口43连接。外部电源80具有商用电源82(例如，AC100V、50Hz)和电源插座81。而且，能够通过将电源插座81与电源插头73连接并且将充电插头71与第1充电端口43连接，从而，将由商用电源82输出的交流电力供给至第1充电端口43。
此外，所述车辆ECU31以及电池ECU12例如能够作为由中央运算处理装置(CPU)、RAM、ROM、硬盘等存储单元构成的一体型的计算机而构成。
在本发明的实施方式中，在使驱动电动机51进行驱动而使车辆行驶时，通过车辆ECU31的控制，将电池11的电力供给至逆变器52，然后，使该逆变器52进行动作，由此产生三相的交流电力，将该交流电力供给至驱动电动机51(三相交流电动机)，使该驱动电动机51进行驱动。另外，能够通过使DC/DC转换器53进行动作而驱动前照灯、雨刷等的弱电仪器设备54。
下面，对将本发明的实施方式所涉及的车辆用电源装置的电池组10所搭载的电池11充电时的动作进行说明。
使用者将充电电缆70的充电插头71插入车辆系统100的第1充电端口43中，然后，将电源插头73插入外部电源80的电源插座81中。这样，由商用电源82输出的电力经由充电电缆70而供给至第1充电端口43，然后，供给至电力供给部41。
图2示意地表示如上所述的电池11的充电的状况，充电电缆70的充电插头71朝向车辆101插入，电流从外部电源80侧向车辆101侧流动。即，充电插头71的插入方向与电流的流动方向成为相同的方向。
另外，图1所示的设置于电池组10中的电池ECU12对电池11的充电状态进行监视，在该电池11处于能够充电的状态的情况下，将该情况的信息输出至车辆ECU31。然后，将继电器13设为接通状态。车辆ECU31将执行对电池11充电的指令信号输出至电力供给部41。该电力供给部41在接收到该指令信号的情况下，将由第1充电端口43供给的交流电力升压为希望的电压，并且，变换为直流电力而输出至电池11。由此，能够将电力充电至电池11。在电池11的充电完毕的情况下，将充电插头71拔出。
此外，在进行快速充电的情况下，能够通过将快速充电用的电力供给装置90与第2充电端口44连接，进行短时间内的充电。
下面，对本发明的实施方式所涉及的车辆系统100中的与插座22的电力的供给、停止的控制相关的动作进行说明。
如果使用者将外部输出开关33接通，则该操作信号输出至车辆ECU31，通过该车辆ECU31的控制，输出DC/AC逆变器21的接通指令以及驱动指令。其结果，电池11的电力供给至DC/AC逆变器21，然后，DC/AC逆变器21动作，将直流电力变换为交流电力(例如，50Hz、AC100V)。然后，供给至插座22。由此，能够通过将电子设备60的插座插头(consentplug)61插入至插座22，使电子设备60进行动作或者充电。
图2(b)示意地表示从如上所述的电池11向电子设备60放电的状况，电子设备60的插座插头61朝向车辆101插入，电流从车辆101(电池11)侧向电子设备60侧流动。即，电子设备60的插头61的插入方向与电流的流动方向成为相反的方向。此外，插座22可以设置在车内，也可以设置在车外。
另一方面，能够通过将图1所示的外部输出开关33断开，使向插座22的电力供给停止。即，如果外部输出开关33断开，则该指令信号输出至车辆ECU31，通过该车辆ECU31的控制，使向DC/AC逆变器21的电力供给停止，并且，由于该DC/AC逆变器21的动作停止，因此，向插座22的电力供给被停止。
此外，在向电子设备60的放电与利用外部电源80等的电池11的充电同时进行的情况下，向电子设备60的电力可以控制为由电池11供给，也可以控制为不经由电池11而由外部电源80等供给。
本发明的实施方式所涉及的车辆ECU31具有作为标记显示单元的功能，该标记显示单元显示充电标记(充电符号)和放电标记(放电符号)，该充电标记表示处于电池11充电过程中，该放电标记表示处于从电池11向电子设备60放电过程中。充电标记以及放电标记例如显示在仪表板等的使用者能够识别的位置处。
图3表示将充电标记2以及放电标记3显示于仪表板1内的情况。充电标记2在电池11的充电时亮灯，在除此以外的情况下灭灯。放电标记3在从电池11向电子设备60放电时亮灯，在除此以外的情况下灭灯。在同时进行电池11的充电以及从电池11向电子设备60的放电的情况下，充电标记2以及放电标记3两者均亮灯。
如图4所示，充电标记2以及放电标记3分别形成为模仿了插头的形状，在本发明的实施方式中，形成为模仿了插座插头的形状。而且，充电标记2以及放电标记3分别具有指示彼此相反的方向的端子2a、3a。即，充电标记2的端子2a是右朝向的，指示右方向。另一方面，放电标记3的端子3a是左朝向的，指示左方向。而且，充电标记2配置在左侧，放电标记3配置在右侧。以充电标记2的端子2a侧与放电标记3的端子3a侧相对的方式配置。
能够通过显示如上所述的充电标记2以及放电标记3，让使用者想到如图5所示的电池11的充放电的状况(图示)。即，将充电标记2的端子2a所指示的方向和放电标记3的端子3a所指示的方向设为相反的朝向，因此，能够容易想到相对于车辆101而言，将充电插头71向车辆101插入的方向和将电子设备60的插座插头61向车辆101插入的方向是相反的朝向。
另外，在通常的电路图中，存在将电源配置于左侧，电流从左向右流动这一原则(铁定的原则)。因此，能够通过将充电标记2的端子2a所指示的方向设为右朝向，从而让使用者容易想到在电池11以及车辆101的左侧配置有外部电源80，电流从左侧的外部电源80流向右侧的电池11以及车辆101的状况。另一方面，能够通过将放电标记3的端子3a所指示的方向设为左朝向，从而让使用者容易想到在电子设备60的左侧配置有作为电源的电池11以及车辆101，电流从左侧的电池11以及车辆101朝向右侧的电子设备60的状况。并且，能够通过将充电标记2设在左侧，将放电标记3设在右侧，从而，作为一个整体而包含有电池11的充电以及放电的状况，让使用者容易想到电流连续从左侧流向右侧的状况，该电池11的充电是指从左侧的外部电源80向电池11以及车辆101充电，该电池11的放电是指从电池11以及车辆101向电子设备60放电。
并且，如图5所示，通过使充电标记2的端子2a侧与放电标记3的端子3a侧相对，能够让使用者容易地想到在充电标记2与放电标记3之间存在1个车辆101以及电池11的状况。
如上所述，根据本发明的实施方式所涉及的车辆用电源装置，能够通过充电标记2以及放电标记3各自模仿具有端子2a、3a的插头形状，将充电标记2以及放电标记3的各自的端子2a、3a所指示的方向设为相反的朝向，从而，让使用者容易地想到将充电插头71向车辆101插入的方向和将电子设备60的插座插头61向车辆插入的方向是相反的朝向。由此，使用者在看到充电标记2时能够明确判断出处于电池11充电过程中、以及在看到放电标记3时能够明确判断出是处于从电池11向电子设备60放电过程中，能够防止将是处于电池11充电过程中还是处于从电池11向电子设备60的放电过程中误认混淆。
另外，通过将具有右朝向的端子2a的充电标记2显示在左侧，将具有左朝向的端子3a的放电标记3显示在右侧，从而，成为以在左侧配置电源、电流从左侧流向右侧这种电路图的铁定原则进行显示。由此，使用者在看到充电标记2时能够明确判断出处于电池11充电过程中、以及在看到放电标记3时能够明确判断出处于从电池11向电子设备60的放电过程中。
另外，如图5所示，通过以充电标记2的端子2a侧与放电标记3的端子3a侧相对的方式进行显示，让使用者想到在充电标记2与放电标记3之间存在车辆101以及电池11的状况。其结果，使用者在看到充电标记2时能够明确判断出处于电池11充电过程中、以及在看到放电标记3时能够明确判断出处于从电池11向电子设备60的放电过程中。
(第1变形例)
另外，充电标记2以及放电标记3的显示位置不限定于图4所示的情况。例如，如图6(a)所示，可以将端子2a右朝向的充电标记2配置在右侧，将端子3a左朝向的放电标记3显示在左侧。另外，如图6(b)所示，也可以上下地显示充电标记2以及放电标记3。
即使是如图6(a)以及图6(b)所示的配置，端子2a、3a所指示的方向也是相反的朝向，因此，能够容易地想到充电时的充电插头71的插入方向和放电时的电子设备60的插头61b的插入方向是相反朝向的状况。
此外，可以是充电标记2的端子2a指示左朝向，放电标记3的端子3a指示右朝向的结构，使得图4的充电标记2以及放电标记3的端子2a、3a所指示的方向是相反朝向。在该情况下，至少端子2a、3a所指示的方向是相反朝向，因此，只要使用者预先识别这些充电标记2以及放电标记3分别表示充电、放电中的哪一个，就能够在看到充电标记2以及放电标记3的显示时明确地进行判断。
(第2变形例)
另外，对于充电标记2以及放电标记3的形状，不限定于模仿为商用电源用的插座插头的形状，只要是能够指示一个方向的形状，也可以是其他的形状。另外，充电标记2以及放电标记3的形状不限定于相同的种类，也可以是不同的种类。
例如，如图7(a)所示，可以将充电标记4形成为模仿普通充电器的枪状的充电插头的形状，而将放电标记3形成为模仿插座插头的形状。充电标记4的端子4a是右朝向的，指示右方向。
另外，如图7(b)所示，可以将充电标记5形成为模仿快速充电器的枪状的充电插头的形状，而将放电标记3形成为模仿插座插头的形状。充电标记5的端子5a是右朝向的，指示右方向。
另外，在图4中，示出了2端子的充电标记2以及放电标记3的，但是，也可以显示大于或等于3端子的充电标记以及放电标记。
(第3变形例)
另外，如图8所示，能够显示普通充电器的枪形状的充电标记4以及快速充电器的枪形状的充电标记5等多个标记，可以在普通充电时以及快速充电时切换显示。
另外，在车辆101中设置有多个插座(plugsocket)的情况下，如图8所示，可以与各插座相对应而显示多个放电标记3x、3y。在该情况下，为了能够分别地识别各放电标记3x、3y，可以标注编号，或者变更颜色、形状。
(第4变形例)
另外，为了让使用者简单地识别是充电过程中还是放电过程中，除了充电标记2以及放电标记3以外，还可以在充电标记2以及放电标记3的附近显示字符串、记号等。例如，在图9所示的例子中，在放电标记3的下部显示“AC－ON”的字符串。
在此引用日本特愿2013－079604号(申请日：2013年4月5日)的所有内容。
以上，围绕本发明的实施方式说明了本发明的内容，但是，本发明不限定于这些记载，对于本领域技术人员而言，当然能够进行各种变形以及改良。
