在现有技术中车载充电装置通常具有多个充电接口,例如1个TYPE-A接口、2个TYPE-C接口。每个充电接口的最大输出功率都是预定的,当充电接口连接不同待充电设备时每个充电接口都会被配置不同的输出功率。例如1个TYPE-A接口和1个TYPE-C接口连接待充电设备时,TYPE-A接口输出功率被预先设定为20W、1个TYPE-C接口输出功率被预先设定为100W;在另一种情况下,多个待充电设备连接到车载充电装置的充电接口上时,车载充电装置又会被配置不同的输出功率,例如1个TYPE-A接口和2个TYPE-C接口连接待充电设备时,TYPE-A接口输出功率被预先设定为30W、2个TYPE-C接口输出功率被分别预先设定为40W,使用者均无法针对其中某个充电接口进行功率设定,从而尽量满足其中一个或者几个待充电设备的快速充电需求。
而在本文的实施例中,用户可以通过车辆的人机界面设定车载充电装置各个充电接口的输出功率,从而使得与车载充电装置不同充电接口连接的待充电设备以不同的输出功率进行充电,从而可以对用户指定的待充电设备进行快速充电。
如图1所示为本文实施例一种车载充电装置的结构示意图,在本图中描述了能够与车辆进行通信的车载充电装置。通过车辆输入的功率分配信息来调节不同充电接口的输出功率,从而实现对与不同充电接口连接的待充电设备(例如手机、平板电脑等)进行用户指定充电功率的输出。该车载充电装置100具体包括:充电模块101、多个充电接口102、主控单元103、通信单元104、电源105、车辆106、待充电设备107。充电模块101连接电源105,通过不同的充电接口102向对应的待充电设备107进行充电。通信单元104,连接于主控单元103与车辆总线之间,用于将车载充电装置100的充电信息传送给车辆106,并接收由车辆106的输入接口输入的针对于不同充电接口102的功率分配信息。主控单元103与充电模块101和通信单元104分别相连接,根据通信单元104接收到的功率分配信息,控制充电模块101向不同的充电接口102提供特定的输出功率。
电源105可以为电池、车载电池或者发电机等设备。充电模块101可以将交流电或者直流电转换为待充电设备107充电的电流。在充电模块101输出充电电流后,充电电流通过充电接口102输入到待充电设备107。在这个过程中,车载充电装置的主控单元103将与不同充电接口102连接的待充电设备107的设备信息等充电信息通过通信单元104发送给车辆106,用户可以通过车辆106的人机界面输入对不同充电接口102的功率分配信息。车辆106将功率分配信息通过通信单元104发送给主控单元103。主控单元控制充电模块101向指定的充电接口102输出特定的输出功率,从而与不同充电接口102连接的对应待充电设备107可以以不同的输出功率进行充电。

在本文的一个实施例中,车辆的输入接口包括人机接口,该人机接口包括旋钮、按键、触摸屏幕、语音交互模块等输入设备之一或者其组合。例如,当在车辆显示屏上显示了某个充电接口的连接待充电设备,以及该待充电设备的目标充电功率,例如目标充电功率包括该待充电设备所能接受的最大充电功率,用户可以通过旋钮的方式调节该充电接口的输出功率,例如提高该充电接口的输出功率至目标充电功率。
如图2所示为本文另一实施例一种车载充电装置的结构示意图,在本图的实施例中同时包括了无线充电部分和有线充电部分。主控单元将有线充电接口和无线充电接口连接的待充电设备的充电信息通过通信单元传送给车辆后,根据车辆发出的对不同充电接口的功率分配信息来向有线充电控制器和无线充电控制器发出功率分配信息。有线充电控制器和无线充电控制器根据功率分配信息来调节各自充电接口的输出功率。该车载充电装置具体包括:外部电源201、有线充电电源202、有线充电接口203、有线充电控制器204、无线充电电源205、无线充电接口206、无线充电控制器207、主控单元208、待充电设备209、通信单元210。该车载充电装置例如还可以包括温度检测单元211、显示单元212、散热单元213。

温度检测单元211用来检测车载充电装置的工作温度,例如可以为温敏电阻,内置于无线充电接口206内,例如功率发射线圈内部或者附近;或者内置于有线充电控制器204附近。散热单元213也可以内置于车载充电装置内部的发热部件附近,从而达到散热、保证装置安全的目的。

如图18所示为本文实施例一种基于前述车载充电装置的功率分配方法流程图,在本图中描述了在上述的车载充电装置的基础之上进行充电控制的方法,该方法可以应用于车载充电装置,该方法具体包括:步骤1801,将车载充电装置的充电信息发送给车辆。步骤1802,接收由车辆的输入接口输入的针对于不同充电接口的功率分配信息。步骤1803,根据功率分配信息,控制充电模块向不同的充电接口提供特定的输出功率。
通过获取用户通过车辆输入接口输入的功率分配信息就可以调节车载充电装置不同充电接口的输出功率,以使得与不同充电接口连接的待充电设备以用户指定的特定输出功率进行充电。当多个充电接口分别连接不同充电设备时,可以根据用户指定的充电接口的输出功率给相应的待充电设备进行快速充电。还可以通过车辆的显示屏显示待充电设备的目标充电功率等信息,以便于用户进行功率分配。
作为本文的一个实施例,充电信息包括以下信息之一或者组合,车载充电装置的充电接口及类型、充电接口连接的待充电设备的设备信息和待充电设备的目标充电功率。
待充电设备的设备信息包括以下信息之一或者组合:待充电设备的名称、待充电设备的品牌和待充电设备的类型。
在本步骤中,由于车载充电装置将获取待充电设备的设备信息和目标充电功率,并可以通过通信单元传送给车辆,在车辆的显示屏上显示车载充电装置的每个充电接口分别与什么待充电设备连接,以用于区分正在充电的待充电设备,并且还可以显示出哪些待充电设备支持快充,所支持的最大充电功率是多少,以方便用户设置与该待充电设备连接的充电接口的输出功率。当然,当用户设置某个充电接口的输出功率提升时,其他的充电接口的输出功率就应当进行相应的降低,主控单元还可以将该车载充电装置的总输出功率也传送给车辆,这样车辆就可以根据车载充电装置的总输出功率自动的降低其他充电接口的输出功率,例如按照剩余输出功率,按比例的降低当前正在进行充电的充电接口的输出功率。
作为进一步的实施例,待充电设备的设备信息还可以包括例如设备名称、待充电设备的品牌和待充电设备的类型(例如手机和平板电脑等),这样车辆显示屏上可以 显示更多待充电设备的设备信息,便于用户准确选择调节对哪个待充电设备的输出功率。
其中,当待充电设备与功率发射线圈接近后,由于车载充电装置的功率发射线圈发射的磁场致使两者之间建立无线充电连接,进一步可以采用现有技术中的QI协议建立双方的通信连接。在建立通信连接之后,待充电设备可以通过请求报文向功率发射线圈发送该待充电设备支持的最大接收功率(可接受的最大充电功率),例如在报文的0X04字段携带有待充电设备的最大接收功率,当然还可以在双方的其他通信报文或者通信报文中的空闲字段携带其他的信息。功率发射线圈将该请求报文通过解码电路恢复为无线充电控制器可读的信息格式,无线充电控制器将该信息通过串口上报给主控单元,以便于主控单元根据该信息来判断该待充电设备是否支持、支持哪种无线充电功率模式,其中无线充电模式例如包括QI BPP(QI Baseline Power Profile)、QI EPP(QI Extended Power Profile)或其他私有充电协议。主控单元根据该信息以及无线输出功率调节无线充电电源的无线输出功率,从而可以进一步提高功率发射线圈的发射功率,使得待充电设备可以接收到最大接收功率来完成快速充电。
作为本文的一个实施例,在将车载充电装置的充电信息发送给车辆之后还包括,车辆将充电信息显示在车辆的显示屏中。
在本步骤中,车辆接收到主控单元发送的充电信息后,可以显示在中控屏幕上,也可以显示在仪表盘的显示器上,用户可以通过车辆现有的输入方式对各个充电接口进行功率分配。主控单元接收到针对不同充电接口的功率分配信息后,控制相应的无线充电控制器或者有线充电控制器进行相应充电接口的输出功率调节。
作为本文的一个实施例,接收由车辆的输入接口输入的针对于不同充电接口的功率分配信息前还包括,车辆的输入接口接收用户对于显示屏中显示的充电接口的功率分配信息。将针对不同充电接口的功率分配信息发送给车载充电装置。
在本步骤中,如图19A所示为本文实施例在车辆显示屏中对充电接口进行功率分配的第一示意图。在本图中,车辆显示屏可以为车辆中控台的显示屏,车载充电装置可能具有4个充电接口,具体包括1个无线充电接口、2个TYPE-C类型的有线充电接口(第一TYPE-C和第二TYPE-C)以及1个TYPE-A类型的有线充电接口。仅有无线充电接口以及第一TYPE-C连接有待充电设备,连接无线充电接口以及第一TYPE-C的待充电设备分别为支持最大无线充电功率40W的第一手机,支持最大有线充电功率100W的第二手机,车载充电装置的总输出功率为120W,当前的功率分配结果为,无线充电接口输出功率为20W,第一TYPE-C输出功率为100W。无线充电 控制器获取了第一手机的无线目标充电功率以及第二手机的有线目标充电功率以及两个手机的设备信息后,将这些信息传送给车辆。车辆的显示器显示了车载充电装置,以及无线充电接口连接有第一手机,该无线充电接口分配到的输出功率为20W,第一TYPE-C连接有第二手机,该第一TYPE-C分配到的输出功率为100W。用户通过显示屏的触摸特性,或者通过按键,选择无线充电接口,会出现如图19B所示为本文实施例在车辆显示屏中对充电接口进行功率分配的第二示意图。如图19B所示,在选中的无线充电接口(虚线框)的旁边出现了调节输出功率的柱状图形,用户通过触摸功能在显示屏上进行上下滑动,从而可以调节无线输出接口的输出功率。在本例中,用户通过向上滑动柱状图形,将无线充电接口的输出功率从当前的20W调节到40W。
同时,如图19C所示为本文实施例在车辆显示屏中对充电接口进行功率分配的第三示意图,在显示屏上的第一TYPE-C处显示的100W输出功率,会随着无线充电接口输出功率的调高而降低,在本例中由于无线输出接口的输出功率调高了20W,则第一TYPE-C处显示的输出功率下降为80W。当用户完成了对车载充电装置充电接口的功率分配后,点击确定按键,或者图标,以将对无线充电接口和第一TYPE-C的功率分配信息通过车辆总线发送给车载充电装置的通信单元,并通过该通信单元发送给主控单元。主控单元向无线充电控制器发送功率调节指令,无线充电控制器通过PWM的方式调节无线充电电源,从而将功率发射线圈输出的充电功率升高至40W。同样,主控单元向有线充电控制器发送功率调节指令,第一TYPE-C对应的有线充电控制器降低该有线充电接口的输出功率至80W。
作为本文的一个实施例,根据功率分配信息,控制充电模块向不同的充电接口提供特定的输出功率进一步包括,若待充电设备的无线目标充电功率和/或有线目标充电功率符合快速充电条件,则使对应的无线充电电源的无线输出功率满足无线目标充电功率,和/或使对应的有线充电电源的有线输出功率满足有线目标充电功率。
在本步骤中,以上的功率分配中,在保证所有输出功率之和小于等于总输入功率的情况下,若无线充电部分通过QI协议获得手机可接受的最大充电功率为快充,例如手机可接受的最大充电功率为40W或50W等,则优先控制无线充电电源输出40W或者50W的无线输出功率(甚至更高的功率),来满足手机的无线充电需求;和/或,也可以根据有线充电部分连接的手机的可接受的最大充电功率为快充,例如手机可接受的最大充电功率为50W或100W等,则优先控制有线充电电源输出50W或者100W的有线输出功率(甚至更高的功率),来满足手机的有线充电需求。
