Description

无线充电发射装置、无线充电系统和电动汽车 技术领域
本发明涉及电动汽车技术领域，特别涉及一种无线充电发射装置、无线充电系统和电动汽车。
背景技术
电动汽车具有节能环保等优点，随着人们环保意识的提高，电动汽车也越来越受到人们的青睐。随着电动汽车的普及，电动汽车的充电技术也应相应跟进。目前，一般通过在充电场所建造插线式的充电桩为电动汽车充电。为提高便利性和用电安全性，越来越多的充电场所正在建造能够进行无线充电的充电桩。
相关技术中的无线充电是通过磁感应式一对一无线充电系统实现的，即一个发射线圈模组与一个接收线圈模组之间通过近场磁场感应实现能量的非接触式传输。充电桩安装有发射线圈模组，可为安装有接收线圈模组的电动汽车充电。
不同类型电动汽车的体积与载重不同，因而充电功率需求也不同。在不同的充电功率需求下，接收线圈的面积和/或匝数不同，对发射线圈的面积和/或匝数的要求也不同。如果发射线圈的面积和/或匝数与接收线圈的面积和/或匝数不匹配，则发射线圈和接收线圈的耦合系数较小，从而导致充电效率较低。举例而言，小型的乘用车体积与载重较小，动力电池的容量较小，所需要的充电功率也较小，因此其接收线圈较小。如果使用大型的发射线圈对其进行充电，则很可能因匝数的不匹配而造成充电效率低下，并且该接收线圈无法覆盖发射线圈的磁场，多余的磁场可能会在其他裸露的金属中形成涡流，进而可能造成该金属熔毁等安全事故。此外，如果一种充电桩仅能为一种类型的电动汽车充电，则必然要对应多种类型的电动汽车建造多种充电桩，这种适用性较差的充电桩将加大充电场所的建造成本与土地需求。

图1为根据本发明一个实施例的无线充电发射装置的结构框图。
如图1所示，本发明实施例的无线充电发射装置，包括：发射线圈10、电源模块20、接收模块30和控制模块40。
其中，发射线圈10包括N个接线端子，其中，N为大于1的整数。电源模块20的第一输出端与N个接线端子中的第一接线端子相连，电源模块20的第二输出端分别通过N-1个可控开关与N个接线端子中的第二至第N接线端子对应相连，即电源模块20的第二输出端通过N-1个可控开关分别与N个接线端子中的第二至第N接线端子一一对应相连。其中，第一接线端子与第二至第N接线端子中任一接线端子之间的线圈面积和/或匝数与第一接线端子与第二至第N接线端子中另一接线端子之间的线圈面积和/或匝数不同。具体地，例如，第一接线端子和第N接线端子可分别从线圈的两端引出，第二至第N-1接线端子可从线圈中的预设位置引出。其中，不同的预设位置与不同的线圈的面积和/或匝数相对应。
具体而言，发射线圈可包括第一接线端子E0，以及第二接线端子E1到第N接线端子E(N-1)。为便于描述，第二至第N接线端子中，第i+1接线端子用Ei表示，i取值为从1到N-1的整数。参见图2，其中以N＝3为例。第一接线端子E0与第二接线端子至第N接线端子中的任一接线端子Ei之间的线圈面积Si和线圈匝数Zi满足：对于不同的i值，各Si不相同和/或各Zi不相同，其中Si表示Ei与第一接线端子E0之间的线圈面积；Zi表示Ei与第一接线端子E0之间的线圈匝数，i取值为从1到N-1的整数。例如，第一接线端子E0和第二接线端子E1之间的线圈面积和/或匝数与第一接线端子E0和第三接线端子E2之间的线圈面积和/或匝数不同。
接收模块30用于接收待充电设备的充电请求信息。控制模块40分别与接收模块30和N-1个可控开关的控制端相连，控制模块40用于根据充电请求信息对N-1个可控开关进行控制，以使电源模块20通过发射线圈10为待充电设备提供电能。其中，充电请求信息包括待充电设备的充电功率信息。具体地，控制模块40可根据充电功率信息控制N-1个可控开关中对应的一个可控开关闭合，并控制N-1个可控开关中其他可控开关打开，以使电源模块20通过对应面积和/或匝数的线圈为待充电设备提供电能。
在具体实施中，所述无线充电发射装置还包括：N-1个可控开关，电源模块20的第二输出端通过N-1个可控开关分别与N个接线端子中的第二至第N接线端子一一对应相连。
图2为根据本发明一个实施例的无线充电发射装置的结构示意图。为便于示例，在图2中N可取3。如图2所示，发射线圈10可包括第一接线端子E0、第二接线端子E1和第三接线端子E2。图3为该发射线圈的结构示意图。如图3所示，发射线圈10可包括铁氧体磁片11和线圈12，其中，线圈12以平面中心对齐的方式固定在铁氧体磁片11上，铁氧体磁片11可用于电磁屏蔽和改善环境磁导率，提高能量传输的效率。第一接线端子E0可位于线圈的一端，第三接线端子E2可从线圈中的预设位置引出，第二接线端子E1可位于线圈的另一端，由此，第一接线端子E0与第二接线端子E1之间的线圈面积S1和/或匝数Z1和第一接线端子E0与第三接线端子E2之间的线圈面积S2和/或匝数Z2不同，即S1和S2不同和/或Z1和Z2不同。电源模块20的第一输出端To1可与第一接线端子E0相连，电源模块20的第二输出端To2可通过可控开关K1与第二接线端子E1相连，并通过可控开关K2与第三接线端子E2相连。由此，在可控开关K1闭合、K2打开时，电源模块20可通过第一接线端子E0和第二接线端子E1与发射线圈10接通，以构成回路；在可控开关K2闭合、K1打开时，电源模块20可通过第一接线端子E0和第三接线端子E2与发射线圈10接通，以构成回路。
在本发明的一个实施例中，如图4所示，在待充电设备侧还可包括接收线圈50和充电控制回路60。其中，接收线圈50还串联有第一电容C3，第一二极管D和第二电容C4，充电控制回路60与第二电容C4并联。待充电设备可通过接收线圈50在发射线圈10产生的电磁场内产生感应电动势，并利用感应电动势为待充电设备提供电能。充电控制回路60可获取待充电设备的充电请求信息，并通过发送模块70将待充电设备的充电请求信息发送至接收模块30。在本发明的实施例中，发送模块70和接收模块30可均为射频模块。
在本发明的实施例中，待充电设备可为电动汽车的动力电池。应当理解，电动汽车动力电池的充电功率越高，其接收线圈的面积和/或匝数越大，为提高发射线圈与接收线圈的耦合系数，相应地，发射线圈的面积和/或匝数也应越大。因此，可根据充电功率信息，控制对应的可控开关闭合，并控制其他可控开关打开，使发射线圈以对应的面积和/或匝数接入回路，从而在电源模块通过发射线圈为动力电池提供电能时，发射线圈与接收线圈的耦合系数达到最优。
根据本发明实施例的无线充电发射装置，根据充电请求信息控制可控开关，以控制发射线圈通过对应的接线端子与电源模块的输出端相连，由此，能够根据电动汽车的充电功率需求等信息选择发射线圈接入电路的面积和/或匝数，提高发射线圈与电动汽车中接收线圈的耦合系数，从而提高了无线充电的效率和安全性。同时，由于该无线充电装置能够适用于充电功率需求不同的电动汽车，适用性较广，能够大大降低充电场所的建造成本。
此外，在本发明的一个实施例中，电源模块的第二输出端与N-1个可控开关中的每个可控开关之间分别串联有谐振电容，即N-1个可控开关K中的每个可控开关K都通过谐振电容与电源模块的第二输出端连接，具体而言，每个可控开关Ki通过谐振电容Ci连接到电源模块的第二输出端，其中i取值为1到N-1的整数。以N＝3为例，参见图2和图4，可通过谐振电容C1与可控开关K1串联，通过谐振电容C2和可控开关K2串联，从而在可控开关K1或K2闭合时分别与发射线圈10构成谐振回路，能够滤除电路中不需要的电信号，并能够调整功率因数，从而提高电路的品质。
在为待充电设备充电的过程中，还可通过相关控制来确保电流的平稳。如图2和图4所示，本发明实施例的无线充电发射装置还可包括电流检测模块80。电流检测模块80用于检测流过发射线圈10的电流值。在本发明的实施例中，接收模块30还接收待充电设备的充电状态信息，控制模块40可根据充电状态信息和电流值对电源模块20进行PID(Proportion Integration Differentiation，比例积分微分)调节。具体地，参照图2和图4，电流检测模块80可包括：第一电阻R和第一放大器A，第一电阻R串联在电源模块20的第一输出端To1与第一接线端子E0之间；第一放大器A的输入端与第一电阻R并联，第一放大器A的输出端与控制模块40相连。在本发明的一个实施例中，充电控制回路60可获取待充电设备的充电状态信息，充电状态信息可为由发送模块70周期性发送的动力电池的荷电状态。由此，控制模块40通过根据动力电池荷电状态和流过发射线圈10的电流值进行PID调节，能够确保充电过程的平稳。
应当理解，发射线圈的输入端需连接交流输入，因此，本发明实施例的无线充电发射装置还可包括电源转换模块。在电源模块的输出为直流输出时，电源转换模块可将电源模块的直流输出转换为交流后输出。
对应上述实施例，本发明还提出一种无线充电系统。
本发明实施例的无线充电系统，包括根据本发明上述实施例的无线充电发射装置，还包括无线充电接收装置，无线充电接收装置包括：充电控制回路，用于获取待充电设备的充电请求信息；发送模块，用于发送充电请求信息；接收线圈，用于将发射线圈产生的电磁场转换为感应电动势，并通过感应电动势为待充电设备提供电能。
无线充电接收装置还包括：相互串联的第一电容和第一二极管，相互串联的第一电容和第一二极管与接收线圈串联；第二电容，第二电容与充电控制回路并联。
更具体的实施方式可参照上述实施例，为避免冗余，在此不再赘述。
根据本发明实施例的无线充电系统，根据充电请求信息控制可控开关，以控制发射线圈通过对应的接线端子与电源模块的输出端相连，由此，能够根据电动汽车的充电功率需求等信息选择发射线圈接入电路的面积和/或匝数，提高发射线圈与电动汽车中接收线圈的耦合系数，从而提高了无线充电的效率和安全性。同时，由于该无线充电装置能够适用于充电功率需求不同的电动汽车，适用性较广，能够大大降低充电场所的建造成本。
对应上述实施例，本发明还提出一种电动汽车。
本发明实施例的电动汽车，包括根据本发明上述实施例的无线充电系统；或者包括根据本公开实施例的无线充电接收装置，相应的无线发射装置设置于充电桩或者充电站，在电动汽车充电过程中，无线充电接收装置和无线充电发射装置配合使用，从而完成充电过程。其具体的实施方式可参照上述实施例，在此不再赘述。
