参见图3、图4，放电插座210包括电阻R4，电阻R4的一端与放电插座210的PE插孔连接，电阻R4的另一端与放电插座的CC1插孔连接；放电车辆200包括供电装置230、放电控制装置220、电阻R1、电阻R6、开关K1、开关K2、开关K3、开关K4和第一车身地GND1，其中，供电装置230的第一极通过开关K1连接至放电插座210的DC+插孔，供电装置230的第二极通过开关K2连接至放电插座210的DC-插孔，第一车身地GND1与放电插座210的PE插孔连接，放电控制装置220分别与放电插座210的CANH插孔和CANL插孔连接，以进行充放电数据传输，放电控制装置220中的辅助电源的第一极通过开关K3与放电插座210的A+插孔连接，辅助电源的第二极通过开关K4与放电插座210的A-插孔连接，电阻R1的一端与放电插座210的CC1插孔连接，并形成第一检测点a，电阻R1的另一端接第一上拉电压U1，电阻R6的一端与放电插座210的CC2插孔连接，并形成第二检测点b，电阻R6的另一端接第二上拉电压U2。
参见图3、图4，充电插座310包括电阻R4’，电阻R4’的一端与充电插座310的PE插孔连接，电阻R4’的另一端与充电插座310的CC1插孔连接。充电车辆300包括电池包330、充电控制装置320、电阻R1’、电阻R6’、开关K5、开关K6和第二车身地GND2，其中，电池包330的第一极通过开关K5连接至充电插座310的DC+插孔，电池包330的第二极通过开关K6连接至充电插座的DC-插孔，第二车身地GND2与充电插座310的PE插孔连接，充电控制装置320分别与充电插座310的CANH插孔和CANL插孔连接，以进行充放电数据传输，充电控制装置320的正供电端与充电插座310的A+插孔连接，充电控制装置320的负供电端与充电插座310的A-插孔连接，电阻R1’的一端与充电插座310的CC1插孔连接，并形成第三检测点a’，电阻R1’的另一端接第三上拉电压U1’，电阻R6’的一端与充电插座310的CC2插孔连接，并形成第四检测点b’，电阻R6’的另一端接第四上拉电压U2’。
需要说明的是，由于图3所示的示例中，放电插座210的CC2插孔和充电插座310的CC1插孔空置，故在图3中未示出放电车辆200的电阻R6和充电车辆300的电阻R4’和R1’。
在本公开的一个实施例中，四个上拉电压U1、U2、U1’、U2’相等，如均为U。
其中，放电控制装置220用于在第一检测点a的电压的减小值大于第一预设值时，判定供电插头110与放电插座210电连接；充电控制装置320用于在第四检测点b’的电压的减小值大于第二预设值时，判定充电插头120与充电插座310电连接。
具体地，参见图3、图4，当开关S断开，且供电插头110的插针未插入放电插座210时，上拉电压U1仅给串联的电阻R1、R4供电，第一检测点a的电压较大；当开关S断开，且供电插头110的插针插入放电插座210时，上拉电压U1给电阻R1、R4、R2、R3供电，其中，串联的R2、R3与R4并联后与R1串联，第一检测点a的电压减小；当开关S闭合，且供电插头110的插针插入放电插座210时，上拉电压U1给电阻R1、R4、R3供电，其中，R3与R4并联后与R1串联，第一检测点a的电压进一步减小。由此，基于电阻R2、R3和开关S的设置，通过第一检测点a的电压值可精确判断供电插头110与放电插座210之间的连接状态。
应当理解，供电装置230与电池包330对应，开关K1、K2与开挂K5、K6对应，电阻R1、R6与电阻R1’、R6’对应，放电控制装置220与充电控制装置320对应。其中，需要说明的是，充电车辆300中应当还设置有与开关K3、K4对应的两个开关，当放电控制装置220判断供电插头110完全插入放电插座210，即供电插头110与放电插座210完全连接时，控制开关K3、K4闭合。
在本公开的实施例中，在充电车辆300充电时，如果充电车辆300的充电控制装置320不需要辅助电源的供电，则放电车辆200可不设置开关K3、K4。
在本公开的一个实施例中，放电车辆200和充电车辆300均还设置有泄放电路、绝缘检测电路。以放电车辆200为例，泄放电路的一端连接在开关K1和供电装置230之间的连线上，泄放电路的另一端连接在开关K2和供电装置230之间的连线上；绝缘检测电路的第一端连接在开关K1和供电装置230之间的连线上，绝缘检测电路的第二端连接在开关K2和供电装置230之间的连线上，绝缘检测电路的第三端与第一车身地GND1连接。并且，上述泄放电路和绝缘检测电路均具备投切功能。
下面结合表1、表2、表3和图5，对图4所示的示例中放电车辆200给充电车辆300的充电过程进行说明。其中，表1示出了图4中各电阻、电压的参数。
表1
Figure PCTCN2020105883-appb-000001
充电控制过程：
1)连接部件与车辆插座插合，使车辆处于不可行驶状态
如图4所示，按下供电插头110的开关S，使开关S处于断开状态，并将供电插头110与放电车辆200的放电插座210插合，插合完成后松开供电插头110的开关S，使开关S恢复至常闭状态，供电插头110与放电插座210完全连接。同样，按照上述操作将充电插头120插入充电车辆300的充电插座310。
其中，在供电插头110与放电插座210的插合过程中，放电车辆200的第一检测点a电压变化过程为：2.5V->2.1V->1.7V/1.3V/0.9V/0.5V，其中，2.5V表示供电插头110与放电插座210未连接，2.1V表示供电插头110与放电插座210半连接，1.7V/1.3V/0.9V/0.5V表示供电插头110与放电插座210完全连接；在充电插头120与充电插座310的插合过程中，充电车辆300的第四检测点b’电压变化过程为：5V->2.5V。
需要说明的是，在连接部件与插座的插合过程中，开关S的打开可作为触发条件，进而在开关S打开时，通过互锁或其他控制措施使车辆处于不可行驶状态。可选地，上述触发条件还可以是打开充放电插座盖门、转接部件与车辆插座连接、对车辆的充放电按钮/ 开关等进行操作。
2)车辆接口连接确认
操作人员对放电车辆200进行充电设置后，放电车辆200的放电控制装置220通过测量第一检测点a的电压值判断供电插头110与放电插座210是否已完全连接，如第一检测点a电压值为1.7V/1.3V/0.9V/0.5V中的一个，则判断供电插头110与放电插座210完全连接。
3)放电车辆自检
在供电插头110与放电插座210完全连接后，闭合开关K3和K4，使低压辅助供电回路导通；闭合接触器K1和K2，进行绝缘检测，绝缘检测时的输出电压应为车辆通信握手报文内的绝缘电压和供电装置230额定电压中的较小值；绝缘检测完成后，将绝缘检测电路以物理的方式从供电回路中分离，并投入泄放电路对充电输出电压进行泄放，放电车辆200完成自检后断开K1和K2，同时开始周期发送通信握手报文。如果充电车辆300需要使用放电车辆200提供辅助电源240，则在得到放电车辆200提供的辅助电源240供电后，充电车辆300的充电控制装置320通过测量第四检测点b’的电压值判断充电插头120与充电插座310是否已完全连接；如果充电车辆300不需要使用放电车辆200提供辅助电压，则充电控制装置320直接测量第四检测点b’电压值判断充电插头120与充电插座310是否连接。如第四检测点b’的电压值为2.5V，则充电车辆300的充电控制装置320开始周期发送通信握手报文。
4)充电准备就绪
充电控制装置320与放电控制装置220在配置阶段时，充电控制装置320控制开关K5和K6闭合，使充电回路导通；放电控制装置220检测到充电车辆300的电池包330电压正常(即确认电池包电压大于供电装置230的最低输出电压且小于供电装置230的最高输出电压)后，控制开关K1和K2闭合，使直流供电回路导通。
5)充电阶段
在充电阶段，充电控制装置320向放电控制装置220实时发送电池充电需求参数，调整充电电流下降时：△I≤20A，最长在1s内将充电电流调整到与命令值相一致；△I＞20A，最长在△I/dlmin s(dlmin为最小充电速率，20A/s)内将充电电流调整到与命令值相一致。放电控制装置220根据电池充电需求参数实时调整充电电压和充电电流。此外，充电控制装置320和放电控制装置220还相互发送各自的状态信息。在充电过程中，充电控制装置320应能检测PE插针断线。
6)正常条件下充电结束
充电控制装置320根据电池系统是否达到满充状态或是否收到“放电车辆中止充电报 文”来判断是否结束充电。在满足以上任一充电结束条件时，充电控制装置320开始周期发送“充电控制装置(或电池管理系统)中止充电报文”，在确认充电电流变为小于5A后断开开关K5和K6。当达到操作人员设定的充电结束条件或收到“充电控制装置(或电池管理系统)中止充电报文”后，放电控制装置220周期发送“放电车辆中止充电报文”，并控制放电车辆200停止充电以不小于100A/s的速率减小充电电流，当充电电流小于等于5A时，断开开关K1和K2。当操作人员实施了停止充电指令时，放电控制装置220开始周期发送“放电车辆中止充电报文”，并控制放电车辆200停止充电，在确认充电电流变为小于5A后断开开关Kl、K2，并再次投入泄放电路，然后再断开开关K3、K4。
7)非正常条件下充电中止
在充电过程中，如果放电车辆200出现不能继续充电的故障，则向充电车辆300周期发送“放电车辆中止充电报文”，并控制放电车辆停止充电，应在50ms内将电流值降至5A或100ms内断开开关K1、K2、K3和K4。
在充电过程中，如果充电车辆300出现不能继续充电的故障，则向放电车辆200发送“充电车辆中止充电报文”，并在300ms内断开开关K5和K6。
在充电过程中，放电控制装置220如确认通讯中断，则放电车辆200停止充电，并断开开关K1、K2、K3和K4。
在充电过程中，放电控制装置220通过对第一检测点a的电压进行检测，如果判断供电插头110的开关S由闭合变为断开，则应在50ms内将输出电流降至5A或以下。
在充电过程中，放电控制装置220通过对第一检测点a的电压进行检测，如果判断供电插头110与放电插座210由完全连接变为断开，则控制放电车辆200停止充电,并断开开关K1、K2、K3和K4。
在充电过程中，供电装置230的输出电压若大于充电车辆300的最高允许充电总电压，则控制放电车辆200停止充电。
当然，如果放电车辆200因严重故障结束充电，则重新启动充电需要操作人员进行完整的充电启动设置。
充电电路原理
1)在放电车辆200和充电车辆300均设置绝缘检测电路，供电插头110与放电插座210插合、充电插头120与充电插座310插合之后，到开关K5、K6闭合充电之前，由放电车辆200负责放电车辆200内部(含充电电缆)的绝缘检查；放电车辆200的绝缘检测电路通过开关从充电直流回路断开，且开关K5、K6闭合之后的充电过程中，由充电车辆300负责整个系统的绝缘检查。充电直流回路DC+、PE之间的绝缘电阻与DC-、PE之间的绝缘电阻(两者取小值R)，当R＞500Ω/V视为安全；100Ω/V＜R＜500Ω/V时，宜进行绝缘 异常报警，但仍可正常充电；R＜100Ω/V视为绝缘故障，应停止充电。
2)放电车辆200进行绝缘检测后，应及时对充电输出电压进行泄放，避免在充电阶段对电池负载产生电压冲击。充电结束后，放电车辆200应及时对充电输出电压进行泄放，避免对操作人员造成电击伤害。泄放电路的参数选择应保证在充电连接器断开后1秒内将供电接口电压降到60VDC以下。
3)因停电等原因，充电回路或控制回路失去电力时，放电车辆200必须在1秒以内断开开关K1、K2或通过泄放电路在1秒以内将充电接口电压降到60VDC以下。
如上所述，放电车辆200可通过第一检测点a与PE间的电阻值(第一检测点a电压值)来判断供电插头110与放电插座是A1否完全连接，以及电缆130的额定电流参数判定，具体连接状态及额定电流参数判定可见表2。

半接状态时，等效电阻相当于R2、R3串联再与R4并联接着与R1串联，检测到的电 压U1均为2.1V。完全连接状态时，等效电阻相当于R3、R4并联，再与R1串联，当电缆组件100中配置的电阻R3、R2阻值不同时，不同的电缆组件100完全连接后，检测到的电压U1是不同的，在U1为1.7V时充电电缆容量为80A，在U1为1.3V时充电电缆容量为125A，在U1为0.9V时充电电缆容量为200A，在U1为0.5V时充电电缆容量为250A。
上述直流充电连接过程和控制时序如图5所示，控制时序说明如表3所示：

Figure PCTCN2020105883-appb-000005
需要说明的是，当充电无预约时，图5中的T0-T7小于10分钟，T5-T6小于30秒；当充电有预约时，T0-T7、T5-T6无时间限制。T4-T5为初始数据交互，完成通讯版本、最高允许充电总电压等数据交互。K3、K4应于放电车辆200发完CSD报文和收到BMS(Battery Management System，电池管理系统)的BSD报文之后才可断开。结束充电后，泄放电路应在开关K1、K2和K5、K6断开后投入，并在残余电压小于60V时退出；且CC1插孔电压由2.1V变为2.5V之后，泄放电路应保持断开状态。
另外，在本公开的实施例中，关于电缆组件100的参数设置还有另外两组数据可供选择，分别如表4、表6所示，其中，表4对应的接口连接状态及额定电流参数判定如表5所示，表6对应的接口连接状态及额定电流参数判定如表7所示。

表4、表6中数据对应的时序图与时序表与表1中数据类似，仅需将时序图中放电车辆200第一检测点a电压值改成相应的数值，时序表中T0—>T2、T19—>T21行中第一检测点a的电压改成相应的数值即可。
三组数据的优缺点：表4中用于检测第一检测点a电压所需器件的精度要求最低，但电阻R1功耗大；表1、表6中的电阻功耗都很小，但表6对应的连接装置额定电流只有三个档位；综合以表1数据为最优。
综上，本公开实施例的电缆组件，为可移动连接装置，能够实现V2V直流充电连接确认，及电缆额定电流参数判断，进而能够保证V2V直流充电的安全性和可靠性。
