请参考图1，图1示出了本发明实施例一提供的充电装置100，该充电装置100包括：
整流器110，耦合于充电桩的CP(Control pilot，控制引导)信号线和保护接地PE(Protecting Earthing，保护接地)线，用于将所述CP信号线输入的电压信号转换为正电压；
电压转换器120，连接于电动汽车的连接控制系统和/或所述电动汽车的充电系统，用于将整流器输出的正电压转换为稳定的供电电压，所述稳定的供电电压用于为所述电动汽车的连接控制系统供电和/或所述电动汽车的充电系统供电。
如虚线框110所示，所述整流器110包括二极管D1，二极管D2，二极管D3，二极管D4；所述CP信号线、D1的正极与D4的负极相连；所述D1的负极与D2的正极相连，所述D1的负极的电压作为所述电压转换器的输入电压；所述D2的负极、D5的正极与PE线相连；所述D4的正极与D5的负极相连。
所述整流器110还包括二级管D3，其为稳压管，所述D3用于在D1的负极输出的电压超过额定电压后将该电压钳位于目标正电压。所述D1的负极与所述D3的负极相连，所述D3的正极与所述D4的正极相连。
所述整流器110具体用于将CP信号线输入的-12V或6V或9V或12V电压整流并分别输出12V或6V或9V或12V电压。示例性的，CP信号线在实际通信过程中，输入的电压为-12V或6V或9V或12V。当输入的电压为负电压时，经过整流器110后，输出的电压为正电压；当输入的电压为正电压时，经过整流器110后，输出的电压为输入的电压。如，当输入的电压为-12V时，输出的电压为12V；当输入的电压为9V时，输出的电压为9V。
具体地，当CP输入为正电压时且PE为正常的零电位时，D1和D5导通，D3的管脚2为正电压，管脚1为参考电平；当CP信号为负电压且PE为正常零电位时，D2和D4导通，D3的管脚2为正电压，管脚1为参考电平。
如虚线框120所示，电压转换器120具体可以包括BOOST电路，所述电压转换器具体用于将整流器输入的6V或9V或12V电压转换为稳定的12V并输出。具体地，考虑到大部分车载电源为12V，因此这里选择BOOST电路，进行升压电平转换。现有的充放电电路的充电管理功耗为4-7W＜12W，CP信号线传输的功率为6 V*2A＝12W，满足充电管理的功率消耗。
所述BOOST电路包括：直流DC-直流DC芯片U4；电容C14和电容C15，所述电容C14和电容C15并联于所述D3，所述D3的负极连接于所述DC-DC芯片的VIN管脚；电阻R17与电阻R13，所述DC-DC芯片的MODE管脚连接所述电阻R17的一端，所述R17的另一端与D3的负极相连，以及所述DC-DC芯片的EN管脚连接电阻R13的一端，所述R13的另一端与D3的负极相连；电容C17，所述电容C17的一端连于所述DC-DC芯片的BST管脚，另一端连于所述DC-DC芯片的SW管脚；电感L2，所述L2的一端连接于所述DC-DC芯片的SW管脚，所述L2的另一端连接于所述DC-DC芯片的VIN管脚；电容C18与电阻R19，所述电容C18的一端与电阻R19相连，C18的另一端与所述DC-DC芯片的COMP管脚相连；电阻R14与电阻R16，所述电阻R14的一端与电阻R16的一端共同连接于所述DC-DC芯片的FB管脚，所述电阻R16的另一端接地，所述R14的另一端连接于所述DC-DC芯片的VOUT管脚。
具体地，C14和C15为输入电容，为所述电压转换器120供电用。R17使芯片工作在PWM模式，R13使芯片默认上电使能开始工作。L2为储能电感。C17为芯片内部开关管供电回路电容。R14和R16为分压电路，为BOOST电路提供电压反馈路径。C18和R19为补偿电路，调整BOOST电路的环路稳定性和动态响应速度。C11和C12和C13为输出电容，为后续电路储能供电。BOOST为开关控制方式，内部开关闭合时，L2储能，VOUT输出为0；内部开关断开时，L2续流，由于参考VIN为低电位，经过L2续流后，VOUT＞VIN。通过配置上述相关器件的参数，可以将上述的6V/9V/12V转换为稳定的12V电压。
所述装置还包括判断电路130，如虚线框所示，所述判断电路用于判断当车载蓄电池的供电电压低于第一阈值时，控制所述电压转换器输出的稳定的供电电压为所述电动汽车的连接控制系统供电和/或所述电动汽车的充电系统供电。
所述判断电路用于判断当车载蓄电池电量高于或等于第一阈值时，控制所述车载蓄电池为所述电动汽车的连接控制系统供电和/或所述电动汽车的充电系统供电，并且控制所述电压转换器输出的稳定的供电电压不再为所述电动汽车的连接控制系统供电和/或所述电动汽车的充电系统供电。
具体地，所述判断电路可以包括N沟道金氧半场效晶体管MOSFET，如图中Q3所示，所述MOSFET的栅极(管脚3)与所述车载蓄电池V_BATTERY相连，所述MOSFET的源极(管脚4/8)与所述电压转换器的输出端相连，所述MOSFET的漏极(管脚1/2/5/6/7)，与所述电动汽车的连接控制系统和/或所述电动汽车的充电系统V_CAR相连。根据蓄电池供电原理，当蓄电池没有电或电量低时供电电压会降低，即若V_BATTERY＜V_Q3.8-0.3V时，其中V_Q3.8为Q3的管脚8输出的电压，Q3导通，则VOUT的输出为连接控制电路和/或所述电动汽车的充电系统供电；当蓄电池电量充足时，V_BATTERY≥V_Q3.8-0.3V，Q3关断，即车载蓄电池为连接控制电路和/或所述电动汽车的充电系统供电。本领域普通技术人员应当了解，使用P沟道MOSFET也可以达到相同的技术目的，为本发明实施例的等同设计。
本发明实施例提供的电路的连接关系如图2所示，其中充电接口可以为国家规范的七孔插座。LI/L2/L3/N直接与充电系统相连以备进行充电。CP/PE信号线与整流器相连。CC/CP/PE与连接控制系统相连。充电系统可以通过或不通过车载系统，与连接控制系统通信。
当充电桩的充电枪插入电动汽车，如果车载蓄电池没有电或电量低，充电桩与电动汽车无法进行充电流程所需要的通信。本发明提供的一种充电装置，能够在在电动汽车的电池没有电的情况下，利用充电桩的CP信号线为连接控制系统供电和/或所述电动汽车的充电系统供电，以使得充电桩能够正常为电动汽车的电池进行充电。并且当蓄电池有足够电量的时候，切换到蓄电池为连接控制系统和充电系统供电，以保证充电桩能够正常为电动汽车的电池进行充电。

步骤310，接收充电桩的控制引导CP信号线输入的电压信号，将所述电压信号进行整流转换为正电压。
步骤320，将所述整流转换后得到的正电压转换为稳定的供电电压，所述稳定的供电电压用于为所述电动汽车的连接控制系统供电和/或所述电动汽车的充电系统供电。
所述接收充电桩的控制引导CP信号线输入的电压信号，将所述电压信号进行整流转换为正电压，包括：将CP信号线输入的-12V或6V或9V或12V电压整流并分别输出12V或6V或9V或12V电压。示例性的，CP信号线在实际通信过程中，输入的电压为-12V或6V或9V或12V。当输入的电压为负电压时，经过整流器后，输出的电压为正电压；当输入的电压为正电压时，经过整流器后，输出的电压为输入的电压。如，当输入的电压为-12V时，输出的电压为12V；当输入的电压为9V时，输出的电压为9V。
所述将所述整流转换后得到的正电压转换为稳定的供电电压，包括：将所述整流转换后得到的6V或9V或12V电压转换为稳定的12V并输出。具体地，考虑到大部分车载电源为12V，因此这里选择BOOST电路，进行升压电平转换。现有的充放电电路的充电管理功耗为4-7W＜12W，CP信号线传输的功率为6V*2A＝12W，满足充电管理的功率消耗。

具体地，上述判断过程可以包括：确认充电枪与电动汽车连接，判断车载蓄电池是否有电或是否电量低，如上所述，可以通过车载蓄电池的供电电压进行判断。如果车载蓄电池的供电电压低于第一阈值，判断所述车载蓄电池电量不足 或没有电，则通过本发明实施例一中提供的电路为控制连接系统和/或充电系统供电。所述控制连接系统与充电桩进行通信，连接且握手成功，所述充电桩为电动车的车载蓄电池进行充电。判断车载蓄电池是否满足连接控制系统的功耗需求，当不满足时，继续由本发明实施例一中提供的电路为控制连接系统和/或充电系统供电；当判断车载蓄电池满足连接控制系统的功耗需求时，本发明实施例一中提供的电路不再为所述电动汽车的连接控制系统供电和/或所述电动汽车的充电系统供电，由车载蓄电池为连接控制系统供电和/或所述电动汽车的充电系统供电。
