除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本申请。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参考图1至图6，本发明的一些实施例提供一种电气系统，电气系统包括电气设备1、第一电池包2和第二电池包3。
在一些实施例中，如图1所示，电气设备1设置成充电器，当第一电池包2或者第二电池包3配接至电气设备1时，电气设备1能够为第一电池包2或者第二电池包3充电。
电气设备1包括设备壳体10，以图1为例，对电气设备1中的前后、上下、左右方向进行定义，将图1所示状态下设备壳体10的纵长延伸方向定义为上下方向，将设备壳体10的宽度方向定义为左右方向，前后方向既垂直于左右方向，又垂直于上下方向。
电气设备1包括电池包安装位100，电池包安装位100设置在设备壳体10上，用于可拆卸地与第一电池包2或第二电池包3配接。
可选的，电气设备1包括在前后方向相对设置的两个电池包安装位100，两个电池包安装位100的结构相同，均可配接第一电池包2或者第二电池包3。
电池包安装位100包括一对第一导向部110a、110b和一对第二导向部120a、120b， 第一导向部110a、110b用于引导第一电池包2沿配接方向A与电气设备1配接，第二导向部120a、120b用于引导第二电池包3沿配接方向A与电气设备1配接，第一导向部110a、110b与第二导向部120a、120b相互独立，且在垂直于配接方向A的宽度方向，一对第一导向部110a、110b位于一对第二导向部120a、120b的两侧。在一些实施例中，如图3所示，配接方向A设置成上下方向中的下方，宽度方向设置成左右方向。
需要说明的是，“第一导向部与第二导向部相互独立”可以理解成，第一导向部的功能与第二导向部的功能相互独立，换句话说，第一导向部用于引导第一电池包2沿配接方向A与电气设备1配接的功能和第二导向部用于引导第二电池包3沿配接方向A与电气设备1配接的功能不会相互交叉。
另外，“一对第一导向部110a、110b位于一对第二导向部120a、120b的两侧”可以理解成，一对第一导向部中的一个110a位于一对第二导向部中的一个120a的外侧，一对第一导向部中的另一个110b位于一对第二导向部中的另一个120b的外侧，且一对第一导向部110a、110b之间的间距大于一对第二导向部120a、120b之间的间距。
如图3和图5所示，第一电池包2沿着一对第一导向部110a、110b从上向下滑动，可使第一电池包2配接至电气设备1；第二电池包3沿着一对第二导向部120a、120b从上向下滑动，可使第二电池包3配接至电气设备1。同理，第一电池包2沿着一对第一导向部110a、110b从下向上滑动，可使第一电池包2与电气设备1脱离配接；第二电池包3沿着一对第二导向部120a、120b从下向上滑动，可使第二电池包3与电气设备1脱离配接。
电气设备1能够适配两种不同接口尺寸的电池包，有利于实现电气设备1的通用性，并且减小了电池包安装位100的尺寸，有利于实现电气设备1的小型化。
进一步的，一对第一导向部110a、110b在宽度方向上彼此间隔开，一对第二导向部120a、120b在宽度方向也彼此间隔开，且一对第一导向部110a、110b和一对第二导向部120a、120b均沿着配接方向A延伸。
可选的，一对第一导向部110a、110b在配接方向A上的尺寸相同，一对第二导向部120a、120b在配接方向A上的尺寸相同。
可选的，一对第一导向部110a、110b的中心线与一对第二导向部120a、120b的中心线重合。具体的，一对第一导向部110a、110b和一对第二导向部120a、120b沿着设备壳体10的中心线对称设置。
可选的，一对第一导向部110a、110b与一对第二导向部120a、120b在配接方向A上至少部分重叠。这样设置，可以减小电池包安装位100的尺寸，有利于实现电气设备1的小型化。
可选的，一对第二导向部120a、120b在垂直于宽度方向的平面的投影区域位于一对第一导向部110a、110b在垂直于宽度方向的平面的投影区域内。
可选的，如图2所示，在配接方向A上，第二导向部120a、120b不超出第一导向部110a、110b限定的区域范围。
可选的，在配接方向A上，第一导向部110a、110b的长度L1与第二导向部120a、120b的长度L2的比值范围为1.5-2，如此设置可以在保证导向部结构强度的前提下，方便电池包从电气装置上插拔。可选的，在配接方向上，第一导向部110a、110b的长 度L1为211mm，第二导向部120a、120b的长度L2为120mm，此时，第一导向部110a、110b的长度L1与第二导向部120a、120b的长度L2的比值约为1.76。
可选的，在宽度方向上，一对第一导向部110a、110b之间的最大距离W1与一对第二导向部120a、120b之间的最大距离W2的比值范围为1.5-2.5，如此设置可以在保证导向部结构强度的前提下，方便电池包从电气装置上插拔。可选的，一对第一导向部110a、110b之间的最大距离W1为135mm，一对第二导向部120a、120b之间的最大距离W2为76mm，此时，一对第一导向部110a、110b之间的最大距离W1与一对第二导向部120a、120b之间的最大距离W2的比值范围约为1.78。
与之相对应的，如图4所示，第一电池包2包括第一壳体20，第一壳体20上设置第一安装位200，第一安装位200包括一对第一配接部210a、210b，一对第一配接部210a、210b用于分别与一对第一导向部110a、110b配合，以实现电气设备1与第一电池包2的配接。如图6所示，第二电池包3包括第二壳体30，第二壳体30上设置第二安装位300，第二安装位300包括一对第二配接部310a、310b，一对第二配接部310a、310b用于分别与一对第二导向部120a、120b配合，以实现电气设备1与第二电池包3的配接。
需要说明的是，第一导向部、第二导向部、第一配接部和第二配接部还可以是其他配合形式，第一导向部、第二导向部、第一配接部和第二配接部不受特征形状、尺寸的限制。
如图2所示，在配接方向A上，第二导向部120a、120b的尺寸L2小于第一导向部110a、110b的尺寸L1，第一导向部110a、110b具有沿配接方向A相对设置的配接始端110c和配接终端110d，第二导向部120a、120b具有沿配接方向A相对设置的配接始端120c和配接终端120d，第一电池包2和第二电池包3与电气设备1配接时相较于配接终端110d、120d均先接触配接始端110c、120c，第二导向部的配接终端120d比第一导向部的配接终端110d更靠近第一导向部的配接始端110c。这样能够让第二电池包3相较于第一电池包2先和电气设备1配接到位，从而避免当电气设备的配接区域外部设置罩壳或者其他遮挡物时，第二电池包3不易从电气设备上取出。
在电压一定的情况下，电池包的能量越大，电池包的容量就越大，电池包内设置的电芯数量也会越多，电池包的重量也会更大，与电池包配接的电气设备需要的承载面积也就更大。但是，电气设备上设置的承载面积也不宜过大，否则，电气设备以及电池包的尺寸会变大，不利于用户携带和使用。需要说明的是，“承载面积”可以理解为一对导向部所限定的配接区域的面积，即一对导向部在配接方向A上的尺寸乘以在宽度方向上一对导向部之间的最大距离所得到的配接区域的面积。
本发明将第一电池包2的能量与一对第一导向部110a、110b限定的配接区域的面积的比值定义为第一能量承载比，将第二电池包3的能量与一对第二导向部120a、120b限定的配接区域的面积的比值定义为第二能量承载比，第一能量承载比的范围为2.05-5.58Wh/cm2，和/或第二能量承载比的范围为1.20-7.20Wh/cm2。
这样设置第一能量承载比和第二能量承载比，使得在满足电池包安装位100对电池包承载需求的情况下，电池包的能量能够尽可能的变大，从而满足电池包单包能力日益增大的使用需求。
可选的，第一导向部110a、110b限定的配接区域的面积为322.5cm2，第一电池包2的能量范围为600-1800Wh，第二导向部120a、120b限定的配接区域的面积为 100cm2，第二电池包2的能量范围为120-720Wh。
可选的，第一电池包2的容量大于第二电池包3的容量。可选的，第一电池包2的容量为11Ah，第二电池包3的容量为4Ah，第一电池包2和第二电池包3的额定电压均为60V。第一电池包2用于为体积大和/或功率高的电动工具供电，例如手推割草机、吹风机等，使用时可以直接将第一电池包2安装在手推割草机上，用户无需直接负担电池包的重量，或者将第一电池包2安装在背架上。第二电池包3用于为手持式电动工具供电，例如打草机、修枝机等，第二电池包3可以直接安装在手持式电动工具上，工作人员在使用手持式电动工具时无需通过线缆为手持式电动工具供电，使用更方便。
可选的，第一电池包2的重量大于第二电池包3的重量。可选的，第一电池包2的重量与第二电池包3的重量的比值范围为2-8。其中，第一电池包2的重量范围为7.5-8.5kg，第二电池包3的重量范围为1.2-3.5kg。
在一些实施例中，如图1所示，一对第一导向部110a、110b背向设置，一对第二导向部120a、120b相向设置。基于此设置，一对第一导向部110a、110b被设置成一对外滑轨，一对第二导向部120a、120b被设置成一对内滑轨，相对应的，如图4和图6所示，一对第一配接部210a、210b被设置成一对内滑轨，一对第二配接部310a、310b被设置成一对外滑轨。
当然，本领域技术人员还可以将一对第一导向部相向设置，即设置成一对内滑轨，一对第二导向部背向设置，即设置成一对外滑轨，相对应的，一对第一配接部设置成一对外滑轨，一对第二配接部设置成一对内滑轨；或者将一对第一导向部和一对第二导向部均设置成一对外滑轨，相对应的，一对第一配接部和一对第二配接部均设置成一对内滑轨；又或者将一对第一导向部和一对第二导向部均设置成一对内滑轨，相对应的，一对第一配接部和一对第二配接部均设置成一对外滑轨。
进一步的，电池包安装位100还包括第一支撑部130和第二支撑部131，一对第一导向部110a、110b包括沿配接方向A延伸的一对第一延伸部111a、111b，一对第二导向部120a、120b包括沿配接方向A延伸的一对第二延伸部121a、121b，第一延伸部111a在宽度方向上从第一支撑部130的外侧凸出设置，第一延伸部111b在宽度方向上从第二支撑部131的外侧凸出设置，第二延伸部121a在宽度方向上从第一支撑部130的内侧凸出设置，第二延伸部121b在宽度方向上从第二支撑部131的内侧凸出设置。
换句话说，一对第一延伸部中的一个111a和一对第二延伸部中的一个121a共用第一支撑部130，一对第一延伸部中的另一个111b和一对第二延伸部中的121b共用第二支撑部131。如此设置，能够使电池包安装位100的布局紧凑，从而减小电池包安装位100所占空间，也就可以减小电气设备1的体积。
需要说明的是，第一支撑部130和第二支撑部131的外侧指的是第一支撑部130和第二支撑部131远离一对第一导向部110a、110b和一对第二导向部120a、120b的中心线的一侧，第一支撑部130和第二支撑部131的内侧指的是第一支撑部130和第二支撑部131靠近一对第一导向部和一对第二导向部的中心线的一侧。在一些实施例中，如图1所示，外侧指的是左侧，内侧指的是右侧。
进一步的，第一导向部110a还包括第一支撑部130的外侧壁132，第一导向部110b还包括第二支撑部131的外侧壁133。相对应的，第一配接部包括用于与第一延 伸部配合的内侧壁，以及与第一导向部的外侧壁配合的第一接触部，如图4所示，以第一配接部210a为例，第一配接部210a包括与第一延伸部111a配合的内侧壁(未示出)，以及与外侧壁132配合的第一接触部211a。由此，当第一电池包2沿配接方向A滑动配接于电气设备1时，第一延伸部111a、外侧壁132、第二延伸部111b以及外侧壁133共同构成对第一电池包2的引导和限位。
同样的，第二导向部120a还包括第一支撑部130的内侧壁134，第二导向部120b还包括第二支撑部131的内侧壁135。相对应的，第二配接部包括用于与第二延伸部配合的外侧壁，以及与第二导向部的内侧壁配合的第二接触部，如图6所示，以第二配合部310a为例，第二配合部310a包括与第二延伸部121a配合的外侧壁312，以及与内侧壁134配合的第二接触部311a。由此，当第二电池包3沿配接方向A滑动配接于电气设备1时，第二延伸部121a、内侧壁134、第二延伸部121b以及内侧壁135共同构成对第二电池包3的引导和限位。
在一些实施例中，如图1所示，电池包安装位100还包括若干位于一对第二导向部120a、120b之间的设备端子140，设备端子140沿宽度方向均匀分布，相对应的，第一电池包2包括若干位于第一配接部210a、210b之间的第一端子(未示出)，第二电池包3包括若干位于第二配接部310a、310b之间的第二端子(未示出)。当第一电池包2与电气设备1配接时，设备端子140用于与相应的第一端子电连接，以实现第一电池包2与电气设备1之间的电力传输；当第二电池包3与电气设备1配接时，设备端子140用于与相应的第二端子电连接，以实现第二电池包3与电气设备1之间的电力传输。
需要说明的是，设备端子140、第一端子以及第二端子可以设置成本领域技术人员容易想到的任何形式，本发明在此不再赘述。
第一电池包2和第二电池包3都能够与设备端子140配接，无需设置两种设备端子，使得结构简单、紧凑，有利于实现电气设备的小型化。
具体地，设备端子140包括正极设备端子和负极设备端子，相对应的，第一端子包括第一正极端子和第一负极端子，第二端子包括第二正极端子和第二负极端子。当第一电池包2与电气设备1配接时，正极设备端子与第一正极端子插接、负极设备与第一负极端子插接，以实现第一电池包2与电气设备1之间的电力传输；当第二电池包3与电气设备1配接时，正极设备端子与第二正极端子插接、负极设备端子与第二负极端子插接，以实现第二电池包3与电气设备1之间的电力传输。

可选的，锁定件150设置成卡扣，第一锁定部250与第二锁定部350设置成与卡扣配合的卡槽。

在与电气设备1配接时，第一电池包2和第二电池包3能够共用设备风口160，使得结构简单、紧凑，有利于实现电气设备的小型化。
在一些实施例中，如图7所示，电气设备1a还可以设置成可供用户背负的背负装置。电气设备1a包括设置在设备壳体10a上的电池包安装位100a，电池包安装位100a用于与第一电池包2或者第二电池包3配接。电气设备1a还包括适配器11a，适配器11a用于与电动工具配接，适配器11a通过线缆12a与电池包安装位100a电连接。当第一电池包2或者第二电池包3配接于电气设备1a，且适配器11a与电动工具配接时，第一电池包2或者第二电池包3能够将电力传递给电动工具。
其中，电池包安装位100a与前述电池包安装位100的结构相同，本发明在此不再赘述。
如图8所示，第一电池包2配接于电气设备1a，在宽度方向上，一对第一导向部110a’和110b’之间的最大距离与一对第一配接部210a和210b之间的最大距离基本相同。其中，第一导向部110a’与第一配接部210a配接，第一导向部110b’与第一配接部210b配接，具体的，第一延伸部111a’与第一电池包2的内侧壁212配合，第一延伸部111b’与第一电池包的内侧壁213配合，第一导向部110a’的外侧壁132与第一接触部211a配合，第一导向部110b’的外侧壁133与第一接触部211b配合，从而第一电池包2能够沿配接方向A滑动安装在电气设备1a上。
如图9所示，第二电池包3配接于电气设备1a，在宽度方向上，一对第二导向部120a’和120b’之间的最大距离与一对第二配接部310a和310b之间的最大距离基本相同。其中，第二导向部120a’与第二配接部310a配接，第二导向部120b’与第二配接部310b配接，具体的，第二延伸部121a’与第二电池包3的外侧壁312配合，第二延伸部121b’与第二电池包3的外侧壁313配合，第二导向部120a’的内侧壁134与第二电池包的第二接触部311a配合，第二导向部120b’的内侧壁135与第二接触部311b配合，从而第二电池包3能够沿配接方向A滑动安装在电气设备1a上。
本发明提供的背负装置，通过在电池包安装位设置第一导向部和第二导向部，不仅可以安装两类电池包，而且可以节省背负装置的空间。
在一些实施例中，电气设备还可以设置成电动工具或者家用电器，电动工具可以设置成割草机、打草机、吹风机等，家用电器可以设置成电风扇、吸尘器等。如图10所示，电气设备1b设置成割草机，电气设备1b包括设置在设备壳体10b上的电池包安装位100b，电池包安装位100b用于与第一电池包2或者第二电池包3配接。当第一电池包2或者第二电池包3配接在电气设备1b时，第一电池包2或者第二电池包3能够给电气设备1b提供电力。
同样的，电池包安装位100b与前述电池包安装位100的结构相同，本发明在此不再赘述。
如图11所示，本发明的一些实施例还提供一种电池包4，电池包4包括电池包壳体40，电池包壳体40上设置电气设备安装位400，电气设备安装位400用于可拆卸 地与第一电气设备或第二电气设备配接。
电气设备安装位400包括一对第一引导部410a、410b和一对第二引导部420a、420b，第一引导部410a、410b用于引导电池包4沿配接方向B与第一电气设备(未示出)配接，第二引导部420a、420b用于引导电池包4沿配接方向B与第二电气设备(未示出)配接，第一引导部410a、410b与第二引导部420a、420b相互独立，且在垂直于配接方向B的宽度方向，一对第一引导部410a、410b位于一对第二引导部420a、420b的两侧。
电池包4能够适配两种不同接口尺寸的电气设备，有利于实现电池包4的通用性，且两种引导部在垂直于宽度方向的平面的投影区域至少部分重叠，减小了电气设备安装位400的尺寸，有利于实现电池包4的小型化。
电气设备安装位400与前述电池包安装位100的结构基本相同，为了方便表述，电池包3与电池包1相同的结构不作重复赘述，不同的结构下面将作详细论述。
在一些实施例中，如图11所示，一对第一引导部410a、410b相向设置，一对第二引导部420a、420b背向设置。基于上述设置，一对第一引导部410a、410b设置成内滑轨，一对第二引导部420a、420b设置成外滑轨，相对应的，第一电气设备上设置一对外滑轨，第二电气设备上设置一对内滑轨。当然，参照前述电池包安装位100的说明，第一引导部和第二引导部的设置也可以是其他形式，在此不再赘述。
进一步的，电气设备安装位400还包括第一连接部430、第二连接部431、第三连接部432和第四连接部433。一对第一引导部410a、410b分别包括沿配接方向A延伸的一对第一凸出部411a、411b，一对第二引导部420a、420b分别包括沿配接方向A延伸的一对第二凸出部421a、421b，第一凸出部411a在宽度方向上从第一连接部430的内侧凸出设置，第一凸出部411b在宽度方向上从第二连接部431的内侧凸出设置，第二凸出部421a在宽度方向上从第三连接部432的外侧凸出设置，第二凸出部421b在宽度方向上从第四连接部433的外侧凸出设置。
同样的，与前述电池包安装位100类似，电气设备安装位400同样包括若干位于一对第一引导部410a、410b之间的电池包端子440、锁定部450以及电池包风口460，这些部件的具体设置方式和结构形态可以参照前述部分，在此不再赘述。这样设置可以让第一电气设备和第二电气设备共用这些部件，使得结构简单、紧凑，从而实现电池包的小型化。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
