现有的适配电动工具的电池包往往需要数小时的充电时间,因此,在用户使用电动工具的过程中,如果电池包的电量耗尽,需要将电池包从电动工具上拆卸,并经过较长时间的充电后,重新将电池包装配至电动工具,才可继续使用,会给用户带来不便。
在本申请实施例中,电动工具***可以包括多种类型的电动工具,例如手持式电动工具、园林式电动工具、智能电动工具等。在一个实施例中,工具***中的电动工具可以使用至少一种储能装置供电,所谓的储能装置是一种能够储存电能、释放电能的电池包。示例性的,电动工具可以采用内置在工具中的电池包供电,也可以采用可拆卸的安装在电动工具上的电池包供电或者同时采用两者供电。
电动工具中设置有安装内置在电动工具中的电池包或者可拆卸的安装在电动工具上的电池包的壳体或者安装部。
在一个实施例中,当电动工具100具有两个储能装置时,如图1所示,机壳102形成有第一安装部1181和第二安装部1182,第一安装部1181用于安装第一储能装置103,第一储能装置103设置为能给电机101供电,第一储能装置103包括至少一个第一储能单元1031。第二安装部1182用于安装第二储能装置104,第二储能装置104设置为能给电机101供电,第二储能装置104包括至少一个第二储能单元1041。在本实施例中,电动工具可以在两个储能装置供电时工作也可以在只有一个储能装置供电时工作。
在一个实施例中,第一储能装置103可以固定安装在第一安装部1181或者可拆卸的安装在第一安装部1181,第二储能装置104可以固定安装在第二安装部1182或者可拆卸的安装在第二安装部1182。
在一个实施例中,电动工具可以包括至少一个电池包接口,能够接入至少一个外部储能装置,该电池包接口的一端用于连接电动工具内置的电池包和/或可拆卸的电池包,另一端连接外部储能装置,以使该外部储能装置为电动工具内置的电池包和/或可拆卸的电池包供电。或者,电池包接口的一端连接电机,另一端连接外部储能装置,以使该外部储能装置为电机供电。可选地,电池包接口112的形状需要与第一储能装置103充电接口形状匹配,以及与第二储能装置104的充电接口形状匹配。
在一个实施例中,如图1所示,电池包接口为两个时,在第一安装部1181中可以设置第一电池包接口1033,第一电池包接口1033包括第一正极端子1034、第一负极端子1035、第一通讯端子1036。在第二安装部1182中可以设置第二电池包接口1043,第二电池包接口1043包括第二正极端子1044、第二负极端子1045、第二通讯端子1046。

在一个实施例中,如图2所示,电池包接口为一个时,第一通讯端子和第二通讯端子可以共用为一个通讯端子300。也就是说,电池包接口为一个时包括第一正极端子1034、第一负极端子1035、第二正极端子1044、第二负极端子1045、共用通讯端子300。可以理解的是,当电动工具100兼容第一储能装置103和第二储能装置104时,可以设置一个电池包接口112,并在该电池包接口112处设置用于连接第一储能装置103的第一正极端子1034、第一负极端子1035,以及用于连接第二储能装置104的第二正极端子1044、第二负极端子1045,以及与外部储能装置通讯的共用通讯端子300,第一储能装置103和第二储能装置104可以共用通讯端子。由此,可以节省空间,节省对机壳102的开口。
在上述示例中,第一正极端子1034,第二正极端子1044,第一负极端子1035,第二负极端子1045均可以伸缩,以避免端子在不使用时裸露在外,端子之间发生短路。
上述示例中,第一正极端子1034或者第二正极端子1044能承受大于或等于100A的电流。第二正极端子1044能承受大于或等于100A的电流持续承受时间至多为5秒。第二负极端子1045能承受大于或等于100A的电流。由此,通过使用电容电池以满足后续快速充电模式的需求。
可选地,第一正极端子和第二正极端子宽度比大于2。
可选地,第一负极端子和第二负极端子宽度比大于2。
可选地,上述示例中的第一正极端子1034、第一负极端子1035、第一通讯端子、第二正极端子1044、第二负极端子1045、第二通讯端子均可以伸缩,以避免端子裸露在电动工具100之外,造成损坏,或者短路。
对于电池包接口与外接储能装置如何连接,外接储能装置通过电池包接口对第一储能装置和第二储能装置如何充电,在后面内容进行描述,此处先不进行相关说明。
在一个实施例中,电池包接口上还可以设置有避空端子,以用于连接外部储能装置时,不同数量端子的外部储能装置可以匹配电池包接口。
在一个实施例中,第一储能单元可以是三元锂电池或者磷酸铁锂电池或者电容电池,第二储能单元可以是电容电池。在一个实施例中,第一储能装置和第二储能装置可以同时给电动工具中的不同模块供电。例如,第一储能装置可以给电机提供主要供电电能,第二储能装置可以给工具中的控制模块或者物联网模块或者照明模块等其他功能模块提供辅助供电电能。在一个实施例中,第一储能装置可以给电动工具供电也可以给第二储能装置充电;第二储能装置给电动工具供电也可以给第一储能装置充电,两个储能装置之间的充放电方式将在后续进行说明,此处暂不做详述。
在一个实施例中,用以为电动工具供电的储能装置可以是电容电池。参考图3所示的工具***10,该工具***10可以包括电容电池1091以及电动工具100,其中电动工具100可以为吹风机100a,也可以为打草机100b,还可以为链锯100c或者骑乘式割草机100d或者电钻100e。在不同工具***中,电容电池1091可拆卸的安装在电动工具的安装部118上,或者能固定在安装部118上。在本实施例中,以一种电动工具即打草机为例进行说明,其他类型的电动工具不再一一列举。
在一个实施例中,当电动工具100具有一个储能装置时,参考图4和图5所示的该电动工具100包括:
电机101;
机壳102,被配置为至少部分包围电机101,机壳102形成有安装部118;
电动工具100还包括电容电池1091,电容电池1091安装至安装部118。
其中,由于电容电池1091可以大倍率放电,并且成本低、续航时间长、安全性高、寿命长、充电快、占位小,以及电池SOC易探测的优势,进而通过电容电池1091给电动工具100供电,以提高电动工具100的性能。
在一个实施例中,电容电池1091可以包括多个电容电池芯,电容电池芯可以是圆柱形,电池芯的长度小于或等于70mm,电池芯的直径大于或等于50mm且小于或等于200mm。
在一个实施例中,安装部118的形状正好可以匹配电容电池1091的形状,以安装电容电池1091。
可选地,如图4所示,机壳102还形成有把手120,把手120供用户握持,安装部118可以设置于把手120。
在一个实施例中,可以在电动工具100的把手120上设置安装部118,从而,节省电动工具100的机身的空间。
可选地,机壳102包括两个相对的半部,安装部118形成在两个相对的半部中的至少一个上。
在一个实施例中,可以在机壳102上设置安装部118,若安装部118是圆柱形,那么可以在一半的机壳上设置半个圆柱形,另一半的机壳上设置另外半个圆柱形,从而在机壳合在一起时,两个半圆柱形可以合成圆柱形安装部。在另外的实施例中,也可以在一半的机壳102上设置圆柱形安装部118。
可选地,如图6所示,该电动工具100还包括与电容电池1091电连接的物联网模块107,电容电池1091向物联网模块107供电。
可选地,如图6所示,还包括与电容电池1091电连接的照明装置108,电容电池1091向照明装置108供电。
其中,物联网模块107设置在电动工具100中,可以实现该电动工具100与其他终端的通信,比如电脑终端,手机终端、其他电动工具或者电池包或者适配器等,从而其他终端可以监控电动工具100中储能装置的性能参数等情况。照明装置108可以在电动工具100作业需要光照时打开。比如在夜间或者视线不好的环境中作业时,可以打开照明装置108。
在一个实施例中,如图5至图7所示,位于电动工具100中的内置的储能装置1091可以给电机101供电,或者,通过电池包接口112连接外部储能装置给电机供电,或者两者同时给电机101供电,或者,通过电池包接口112连接外部储能装置给内置的储能装置109供电。
由此,通过设置电容电池给电动工具供电,使得电动工具的供电装置具有放电倍率更大,成本更低,续航时间更长等优势。
在一个实施例中,如图8所示,在电动工具100包括第一储能装置103和第二储能装置104的基础上,还增加了控制器106和充电电路105。该控制器106和充电电路105用于第一储能装置103向第二储能装置104充电,或者,用于第二储能装置104向第一储能装置103充电。
可以理解的是,第一储能装置103可拆卸的安装在机壳102上,当电动工具100的电机工作需要用电时,第一储能装置103可以为电动工具100供电;当电动工具100不需要用电时,第一储能装置103可以拆卸下来安装至其他电动工具上,给其他电动工具供电,以实现一块儿电池多机使用;或者当电动工具100的电机工作需要用电,而第一储能装置103电量低时,可以将第一储能装置103拆卸下来,更换新的第一储能装置。另外,第一储能装置103还可以在第二储能装置104需要充电时,且自身在满足充电的条件下为第二储能装置104充电。
在另一个实施例中,第二储能装置104可拆卸的安装在机壳102上,当电动工具100的电机工作需要用电时,第二储能装置104可以为电动工具100供电;当电动工具100不需要用电时,第二储能装置104可以拆卸下来安装至其他电动工具上,给其他电动工具供电,以实现一块儿电池多机使用;或者当电动工具100的电机工作需要用电,而第二储能装置104电量低时,可以将第二储能装置104拆卸下来,更换新的第二储能装置104。另外,第二储能装置104还可以在第一储能装置103需要充电时,且自身在满足充电的条件下为第一储能装置103充电。
第一储能装置103和第二储能装置104,均为可以提前储存电能的装置。由此,避免了用户使用电动工具100作业时,通过拉线接电源的不便。并且可以通过更换第一储能装置103,或重新为第一储能装置103充电的方式来使得电动工具100可以重新工作,极大的方便的用户的使用。
在一个实施例中,充电电路15可以包括功率开关元件(开关管),当控制器106判断第二储能装置104需要充电时,可以控制充电电路15中的功率开关元件导通,使第一储能装置103向第二储能装置104充电。电动工具100内部的一个储能装置向另外一个储能装置充电,减少了充电接口的设置。当控制器106判断第二储能装置104不需要充电时,可以控制充电电路15断开,以切断第一储能装置103与第二储能装置104之间的电路。
具体来说,如何判断第二储能装置104需不需要充电有以下方法得出,如图10所示,控制方法包括:
S101,检测第一储能装置103和第二储能装置104的剩余电量;
S102,根据第一储能装置103和第二储能装置104的剩余电量控制第一储能装置103给第二储能装置104充电。
可选地,根据第一储能装置103和第二储能装置104的剩余电量控制第一储能装置103给第二储能装置104充电包括:
当第一储能装置103的剩余电量大于或等于第一预设电量,且第二储能装置104的剩余电量小于或等于第二预设电量时,控制第一储能装置103给第二储能装置104充电。
可以理解的是,在第一储能装置103和第二储能装置104可以共同为电机101供电时,控制器106可以实时检测第一储能装置103和第二储能装置104的剩余电量,当第一储能装置103的剩余电量大于或等于第一预设电量,且第二储能装置104的剩余电量小于或等于第二预设电量时,控制第一储能装置103给第二储能装置104充电。其中,第一预设电量可以为第一储能装置103总电量的1/3,第二预设电量可以为第二储能装置104总电量的1/10。也就是说,第一储能装置103在满足自身电量的情况下,并且第二储能装置104需要充电的情况下,控制器106可以控制第一储能装置103向第二储能装置104进行充电。从而,减少了对第二储能装置104的外部充电端子的设置。自第一储能装置103向第二储能装置104充电,更加方便快捷。
上述示例中,检测剩余电量可以通过电池电量管理器来检测。
其中,在一个实施例中,第一储能装置103和第二储能装置104可以分别单独为电动工具供电,也可以同时为工具供电。例如,第一储能装置103和第二储能装置104可以在电动工具100需要大功率输出或者大扭矩输出等工况时,共同向电动工具100供电。
可选地,如图9所示,该电动工具100还包括与第二储能装置104电连接的物联网模块107,第二储能装置104向物联网模块107供电。该电动工具100还包括与第二储能装置104电连接的照明装置108,第二储能装置104向照明装置108供电。
在上述示例中,第二储能装置104与第一储能装置103的容量比值小于等于1。
在一个实施例中,如图11所示,在电动工具100具有一个储能装置109的基础上,通过外部充电器200给该储能装置109来充电。或者,在有两个储能装置,但仅保留有一个储能装置的充电接口,另一个储能装置由该储能装置进行内部充电的基础上,当通过电池包接口112连接外部储能装置给留有电池包 接口的储能装置109供电时,储能装置109包括暴露于机壳102表面的接触式端子,充电接口201包括与接触式端子匹配的端子。或者,储能装置109紧贴于机壳102内,充电接口201包括无线充电线圈。或者,电动工具100还包括电池包结合部,用于可拆卸地安装电池包,电池包能给储能装置109充电。
也就是说,被充电的储能装置109可以为电动工具100的电机101进行供电,可以位于电动工具100中。总结来说,外部储能装置可以通过三种充电方式为该储能装置109进行充电。如图12所示,第一种方式为:通过在充电接口201处设置接触式端子,在储能装置109上也设置接触式端子,充电接口201与储能装置109上的端子进行接触时,充电器200可以为储能装置109充电,该种方式可以降低充电时的接触不良。如图13所示,第二种方式为:通过在充电接口201中设置无线充电线圈,来对储能装置109通过无线充电的方式进行充电,该种方式可以减少电线的布置。第三种方式为:在电动工具100中设置可拆卸的电池包,通过电池包给储能装置109充电,该种方式充电更加便捷。由此,通过接触端子、无线充电线圈、以及电池包三种方式来对储能装置109进行充电,使得储能装置109在需要电量时,可以及时得到补充。
可选地,充电器200为储能装置109充电的充电倍率大于或等于5C且小于50C。
在一个实施例中,如图14和图15所示,电动工具100包括第一储能装置103和第二储能装置104,当该两个储能装置均通过充电器200充电时,充电器200包括识别单元206、控制单元207和充电模式设定单元202。可以理解的,充电器200还包括一个充电接口201。
需要说明的是,第一储能装置103和第二储能装置104可以位于电动工具100中,其中,第一储能装置103中的第一电池包接口1033中的第一通讯端子1036可以与充电接口201中的通讯端子205进行通讯,进而,识别单元206可以识别到通讯端子205与第一通讯端子1036进行通讯,控制单元207依据识别单元206识别的信息控制充电器200向第一储能装置103充电。同样的,第二储能装置104中的第二电池包接口1043中的第二通讯端子1046可以与充电接口201中的通讯端子205进行通讯,进而,识别单元206可以识别到通讯端子205与第二通讯端子1046进行通讯,控制单元207依据识别单元206识别的信息控制充电器200向第二储能装置104充电。其中,充电器200向第一储能装置103充电时,充电接口201中的正极端子203可以与第一正极端子1034电连接,负极端子204与第一负极端子1035电连接,以对第一储能装置103充电。充电器200向第二储能装置104充电时,充电接口201中的正极端子203可以与第二正极端子1044电连接,负极端子204与第二负极端子1045电连接,以 对第二储能装置104充电。
在一个实施例中,充电接口201为一个,但可以包括两组正负极端子,并且可以伸缩。
也就是说,充电接口201可以包括第一充电正极端子、第一充电负极端子、第二充电正极端子、第二充电负极端子,如此设置,可以匹配不同的储能装置类型。充电器200向第一储能装置103充电时,充电接口201中的第一充电正极端子可以与第一正极端子1034电连接,第一充电负极端子与第一负极端子1035电连接,以对第一储能装置103充电。充电器200向第二储能装置104充电时,充电接口201中的第二充电正极端子可以与第二正极端子1044电连接,第二充电负极端子与第二负极端子1045电连接,以对第二储能装置104充电。其中,两组正负极端子可伸缩,也就是,充电接口201与第一电池包接口1033耦合时,第一组正负极端子伸出,第二组正负极端子收缩,充电接口201与第二电池包接口1043耦合时,第二组正负极端子伸出,第一组正负极端子收缩。避免正负极端子裸露在外,端子之间发生短路。
在一个实施例中,在充电接口201包括两组正负极端子的基础上,充电接口201中的每组正负极端子均可以设置在一个充电接口中。也就是说,如图16所示,第一组正负极端子设置在第一充电接口2011中,第二组正负极端子设置在第二充电接口2012中。第一充电接口2011能够与第一接口1033耦合;第二充电接口2012能够与第二接口1043耦合。耦合的方式可以包括接触端子、无线充电线圈、以及电池包三种方式进行耦合。
充电器200还包括控制单元207,控制单元207分别与第一充电接口2011、第二充电接口2012和充电模式设定单元202电连接,当第一充电接口2011与第一储能装置103耦合时,控制单元207控制充电器200以普通充电模式对第一储能装置103充电;当第二充电接口2012与第二储能装置104耦合时,控制单元207控制充电器200根据充电模式设定单元设定的充电模式对第二储能装置104充电。
可以理解的是,如图17所示,当以接触端子进行耦合时,该充电器200包括第一充电接口2011和第二充电接口2012,其中,第一充电接口2011包括第一充电正极端子20111、第一充电负极端子20112和第一充电通讯端子20113;第二充电接口2012包括第二充电正极端子20121、第二充电负极端子20122和第二充电通讯端子20123。
在第一储能装置103的第一电池包接口1033中可以包括第一正极端子、第一负极端子、第一通讯端子,在第二储能装置104的第二电池包接口1043中可以包括第二正极端子、第二负极端子、第二通讯端子。由此,当第一通讯端子 与第一充电通讯端子通讯时,第一充电接口2011与第一接口1033耦合,从而,第一充电正极端子与第一正极端子电连接,第一充电负极端子与第一负极端子电连接,充电器200以对第一储能装置103充电;当第二通讯端子与第二充电通讯端子通讯时,第二充电端口2012与第二接口1043耦合,从而,第二充电正极端子与第二正极端子电连接,第二充电负极端子与第二负极端子电连接,充电器200以对第二储能装置104充电。在充电器200上设置两个充电接口,在一定情况下可以同时对第一储能装置103和第二储能装置104进行充电,并且两组端子的设置,可以适应不同类型的储能装置端子。
其中,上述的各通讯端子可以为蓝牙、WiFi、射频等通讯器件。
可以理解的是,充电器200向第一储能装置103(三元锂电池或磷酸铁锂电池)充电时,以普通充电模式向第一储能装置103充电。充电器200向第二储能装置104(电容电池)充电时,以普通充电模式或快速充电模式向第一储能装置103充电。充电模式可以通过充电模式设定单元202来进行设定。
普通充电模式的充电倍率小于5C。快速充电模式的充电倍率大于或等于5C且小于50C,C为充放电率的单位。通过充电倍率大于5C可以在20分钟以内将电池充满,小于50C是因为对电池充电配电线路耗电低,发热量小,可以不设置散热板。
在一个实施例中,电动工具中的储能装置通过电池包充电时,该电池包包括:壳体;电动工具接口,用于与所述电动工具连接,所述电动工具接口包括端子组件;多个电芯单元,容纳于所述壳体,所述多个电芯单元以组合的串并联配置连接,所述多个电芯单元与所述端子组件电连接;所述多个电芯单元是电容电池;充电控制单元,用于对所述多个电芯单元进行充电控制。
需要说明的是,电池包中设置有多个电芯单元,多个电芯单元均为电容电池,由此,当电池包为电动工具供电或者为第一储能装置或第二储能装置充电时,充电速率快,使用寿命长。
在一个实施例中,电动工具100包括第一储能装置103和第二储能装置104时,第二储能装置104在一定条件下才向电机101供电。如图18所示,第二储能装置104与电机101之间设置有开关电路111,当第一储能装置103的电压低于第二储能装置104时,开关电路111接通以使得第二储能装置104为电机101供电。
开关电路111包括二极管。
正常情况下,电动工具100的电机101工作时,由第一储能装置103供电,当第一储能装置103的电压低于第二储能装置104的电压时,开关电路111接 通。
需要说明的是,第一储能装置103供给给电机101的电压可以通过电机101的供电线路来获取,开关电路111的一端的电压为第一储能装置103供给给电机101的电压,另一端的电压为第二储能装置104的电压,当开关电路111连接电机101一端的电压低于第二储能装置104的电压时,开关电路111接通,以使得第二储能装置104为电机101供电。举例来说,开关电路111可以为二极管,二极管的阴极连接电机101,二极管的阳极连接第二储能装置104。在二极管两端的电压差出现变化时,二极管导通。其中,第一储能装置103的最高电压与第二储能装置104的电压之间的压差小于二极管本身的击穿电压。
开关电路111还包括同步整流管。
同步整流管的栅极连接第二储能装置104,漏极连接电机101,当栅极和漏极之间的电压为正时,同步整流管导通,从而使得第二储能装置104为电机101供电。
开关电路111包括场效应管。如图19所示,开关电路111包括场效应管时,电动工具100还包括控制器106,控制器106用于检测场效应管的两端电压并控制场效应管的通断。
该场效应管两端的电压通过控制器106检测,当第一储能装置103的电压低于第二储能装置104的电压时,控制开关电路111导通,从而使得第二储能装置104为电机101供电。反之,当第一储能装置103的电压高于第二储能装置104的电压时,控制开关电路111断开,以切断第二储能装置104向电机101供电。
在上述示例中,开关电路111中,PCB铜箔宽度大于或等于1.5cm。开关电路111中,PCB铜箔开窗。进而,通过增加PCB铜箔的厚度,或在将PCB铜箔开窗的方式,增加铜箔过电流能力,以适应第二储能装置104的放电回路电流较大的情形。
由此,在该实施例中,通过开关电路111来实现第一储能装置103的电压不足时,及时导通第二储能装置104来为电机101供电,以使得电机101在作业过程中可以连续工作,避免电机101由于电压低而造成作业中断。
在一个实施例中,如图20所示,在电动工具100设置开关电路111的基础上,除了监测第一储能装置103和第二储能装置104的电压参数之外,还可以通过控制器106检测第一储能装置103的工作参数来控制开关电路111的导通或关断。
可选地,工作参数可以是SoC(荷电状态/剩余电量)。或者,工作参数可 以是SoH(蓄电池容量、健康度、性能状态)。
可以理解的是,控制器106可以实时检测第一储能装置103的工作参数,比如SoC和/或SoH。当检测的工作参数是SoC时,若第一储能装置103的SoC参数低于预设阈值时,控制器106控制开关电路111导通,以使得第二储能装置104可以通过开关电路111向电机101供电。若第一储能装置103的SoC参数高于预设阈值时,控制器106可以控制开关电路111关断,以使得第二储能装置104停止向电机101供电。其中,开关电路111可以为开关管(三极管或者MOS管)。
当检测的工作参数是SoH时,若第一储能装置103的SoH参数低于设定阈值时,说明第一储能装置103的性能下降,控制器106可以控制开关电路111导通,以使得第二储能装置104可以通过开关电路111向电机101供电。若第一储能装置103的SoH参数高于设定阈值时,控制器106可以控制开关电路111关断,以使得第二储能装置104停止向电机101供电。
当检测的工作参数是SoC和SoH时,若第一储能装置103的SoH参数、SoC参数中的任意一个参数低于阈值时,控制器106可以控制开关电路111导通,以使得第二储能装置104可以通过开关电路111向电机101供电。反之,控制器106可以控制开关电路111关断,以使得第二储能装置104停止向电机101供电。控制器106检测第一储能装置103的工作参数为多个时,可以对第一储能装置103进行多方面的检测,进而可以及时的检测到第一储能装置103的不足,以及时打开开关电路111,使得第二储能装置104对电机101进行供电,对电机101的供电进行及时补充,保证了电机101的连续作业。
上述实施例说明了第二储能装置104在一定条件下向电机101供电。在另一个实施例中,还可以选择其他方式来控制第一储能装置103和/或第二储能装置104向电机101供电。
如图21和图22所示,第一储能装置103和第二储能装置104可统称为电源组件113,电源组件113为电机101供电,也就是说,第一储能装置103和/或第二储能装置104可以为电机101供电。举例来说,当第一储能装置103为电机101供电时,第二储能装置104闲置;或者,当第二储能装置104为电机101供电时,第一储能装置103闲置;或者,第一储能装置103和第二储能装置104同时为电机101供电。并且在上述的供电示例中,第一储能装置103和第二储能装置104中的至少一个的放电倍率大于等于10C且小于等于50C,以以保证在电机101可以正常工作的基础上,保护整个放电电路不被大电流烧毁。
可选地,如图22所示,还包括放电单元114,放电单元114包括第一放电开关115,当第一放电开关115接通时,第一储能装置103给电机101供电;放 电单元114还包括第二放电开关116,当第二放电开关116接通时,第二储能装置104给电机101供电。
可选地,当电动工具100处于稳定工况时,第一放电开关115接通;当电动工具100处于大电流工况时,第一放电开关115和第二放电开关116同时接通。
在一个实施例中,工具工作于稳定工况时至少一个储能装置的放电倍率小于等于30C;工具工作于大电流工况时,至少一个储能装置的放电倍率大于30C。
在一个实施例中,第一放电开关115和第二放电开关116可以外设为按钮,根据用户需求进行触发,其中,当第一放电开关115接通时,比如为一档工况,第二放电开关116接通时,比如为二档工况,当第一放电开关115和第二放电开关116均接通时,比如为三档工况,每一档的工况不同。由此,通过放电单元114的设置,可以直接根据用户的需求自主控制第一储能装置103和/或第二储能装置104向电机101供电。
第一放电开关115和第二放电开关116均可以为机械开关。
由此,可以在第一储能装置的电压不能够提供电机的供电时,可以接通第二储能装置为电机供电,以及时对电机的供电进行补给,或者在用户触发,或者根据不同工况触发相应储能装置给电机101供电,以保证电动工具的连续作业。
在一个实施例中,如图23所示,第一储能装置103可拆卸的安装在电动工具100上,第一储能装置103与第一控制模块121连接,第一控制模块121用于检测第一储能装置103的电量,并发送至第二控制模块122,第二控制模块122与第二储能装置104连接,用于检测第二储能装置104的电量,当电动工具100处于稳定工况时,第一放电开关115打开,第一储能装置103通过第一放电开关115给电机101供电,当电动工具100处于瞬时大电流工况时,第二控制模块122控制第二放电开关116打开,第一储能装置103和第二储能装置104同时为电机101供电。并当第二控制模块122检测到第二储能装置104电量低时,且第一控制模块121检测到第一储能装置103的电量满足充电要求时,可以控制充电电路105打开,使第一储能装置103向第二储能装置104充电。
在一个实施例中,如图24所示,第二储能装置104还可以通过第二放电开关116给物联网模块107和/或照明装置108供电。
在一个实施例中,如图25和图26所示,若只有一个储能装置给电机101供电,可以通过第一控制模块121检测储能装置的电量,第二控制模块122根据储能装置的电量来控制放电开关的打开或关闭,以给电机101供电,或断电。
在一个实施例中,第一储能装置103可以是锂电池包,第二储能装置104可以是电容电池包。电动工具可以兼容锂电池包和电容电池包获得电能。
在一个实施例中,如图27所示,在电动工具100包括第一储能装置103和第二储能装置104的基础上,还增加了温度检测装置117和控制器106,其中,温度检测装置117,用于检测第一储能装置103的温度并发送给控制器106;温度检测装置117设置在第一储能装置103内。也就是,温度传感器可以直接是在第一储能装置103内。
在一个实施例中,如图28所示,机壳102形成有安装部118,第一储能装置103安装至安装部118,温度检测装置117设置在安装部118。由此,通过安装部118安装第一储能装置103和温度检测装置117更加集中,温度检测装置117可以更好的检测第一储能装置103的温度。
控制器106用于当第一储能装置103的温度小于等于第一预设温度且大于等于第二预设温度时,控制器106控制第二储能装置104给第一储能装置103预热。
可以理解的是,第一储能装置103给电机101供电,但是储能装置一般都有合适的工作温度区间,当处于低温环境,即低于合适的工作温度,储能装置的放电效率都会变低。由此,需要保证第一储能装置103的工作温度。
温度检测装置117检测第一储能装置103的温度,当第一储能装置103的温度位于第二预设温度和第一预设温度之间时,控制器106可以控制第二储能装置104给第一储能装置103预热。当大于第一预设温度时,可以停止第二储能装置104给第一储能装置103预热。其中,第二预设温度为-40℃。第一预设温度为-20℃。由此,当电动工具100处于较低温度环境中使用时,第二储能装置104给第一储能装置103预热,避免第一储能装置103处于低温环境中放电性能受到影响,以保证电机101正常作业。
上述示例过程中的温度检测装置117可以为温度传感器。
在一个实施例中,预热的方式主要有,控制器106控制第二储能装置104给第一储能装置103预热时,第二储能装置103给一负载放电,负载邻近第一储能装置103。
可以理解的是,该负载可以是电阻,电热丝等,通过第二储能装置103给电阻或者电热丝放电,进而加热电阻或者电热丝,又由于负载邻近第一储能装置103,进而电阻被加热的热量,或者电热丝被加热的热量可以传递给第一储能装置103,以给第一储能装置103预热。
在一个实施例中,预热的方式主要有,第二储能装置104与第一储能装置 103通过导热材料物理连接。
其中,导热材料可以为导热性能好的金属,比如铜,铝等,还可以为其他的导热材料,本申请对此不作具体限定。通过导热材料物理连接第一储能装置103和第二储能装置104,当第二储能装置104放电时,可以对导热材料进行加热,从而通过导热材料热传递至第一储能装置103,给第一储能装置103预热。
在一个实施例中,预热的方式主要有,第二储能装置104与第一储能装置103邻近。
在其他的实施例中,第二储能装置104与第一储能装置103邻近,控制器106可以控制第二储能装置104直接对第一储能装置103放电,以对第一储能装置103进行预热。
为了节省能耗,避免温度传感器一直处于检测状态,如图29所示,电动工具100还包括开机单元119,开机单元119用于向控制器106发送第一信号,当控制器106接收到第一信号且第一储能装置103的温度小于等于第一预设温度且大于等于第二预设温度时,控制第二储能装置104给第一储能装置103预热。
在一个实施例中,第一信号产生的方式有,开机单元119包括致动器,当致动器***作至预设位置时,开机单元119向控制器106发送第一信号。
也就是说,当电动工具100开机之后,温度检测装置117才开始检测第一储能装置103的温度,并当第一储能装置103的温度小于等于第一预设温度且大于等于第二预设温度时,控制第二储能装置104给第一储能装置103预热。避免温度检测装置117一直检测第一储能装置103的温度,第二储能装置104一直给第一储能装置103预热,以节省能耗。开机单元119可以包括致动器,可以理解为电动工具100的开关按钮。
在一个实施例中,第一信号产生的方式有,电动工具100还包括无线通信接口,无线通信接口用于使电动工具100与远程设备通信连接,当开机单元119接收到远程设备发送的待机信号时,发送第一信号给控制器106。
也就是说,可以通过远程设备发送待机信号,比如,当用户还未达到施工现场时,便可以远程操作,先给第一储能装置103预热,等用户到达施工现场,第一储能装置103已经预热好,可以直接使用,节省了时间。
在一个实施例中,如图30所示,在电动工具100,包括一个储能装置的基础上,还设置了电路板组件123,用于驱动电机101转动;以及温度检测装置117,用于检测电路板组件123的至少一个元件的温度并发送给控制器106;控制器106被设置为当温度检测装置117发送的温度小于等于第一预设温度且大于等于第二预设温度时,控制器106控制储能装置109给电路板组件123的至 少一个元件预热。
需要说明的是,电路板组件123可以理解为储能装置109输出的直流电转变为交流电供给给电机101的组件,比如可以为逆变器。在低温下,电路板组件123中有些电子元件可靠性不太好,进而在使用电动工具100前,需要先对电路板组件123预热。具体方式为,温度检测装置117检测电路板组件123的至少一个元件的温度,并当温度小于等于第一预设温度且大于等于第二预设温度时,可以控制储能装置109给电路板组件123预热。
具体来说,储能装置109给电路板组件123预热的方式有三种,一种是,储能装置109邻近电路板组件123,靠储能装置109自己发热,热传递至电路板组件123。另一种是,通过导热材料物理连接电路板组件123和储能装置109,通过储能装置109放电自身放热,通过导热材料热传递至电路板组件123,具有传热快的特点。再一种直接给电路板组件123上的电阻放电,加热电阻,以预热电路板组件123,具有预热直接,快捷的特点。实际应用时,可以任选其中一种方式预热,或者设置三种方式,但根据温度区间的不同选择不同的预热方式。其中,为了减少空间,控制器106可以集成设置于电路板组件123上。电路板组件123包括耐低温的电子元件。电路板组件123包括不耐低温的电子元件。
在图30的实施例基础上,也可以设置开机单元119,来节省能耗。
可选地,如图31所示,在图30的实施例基础上,电动工具100还包括第二储能装置104,第二储能装置104为电机101供电。可以理解的是,通过设置第二储能装置104可以在储能装置109电量低时,及时对电机101进行供电,以供电机101连续工作。
在一个实施例中,储能装置给电机供电的同时,还可以给电动工具的把手120来进行预热。如图32所示,温度检测装置117用于检测把手120的温度并发送给控制器106;当把手120的温度小于等于第一预设温度且大于等于第二预设温度时,控制器106控制储能装置109给把手120预热。其中,储能装置109设置于把手120内,有利于直接给把手120预热,减少预热路径的热量损耗。
可以理解的是,当电动工具100处于低温环境中时,用户手持电动工具100作业,用户体感会比较冷,进而可以通过对把手120预热的方式来降低用户寒冷的感受。其中,储能装置109给把手120预热的方式可以参照前述两个示例中给第一储能装置103和电路板组件123预热的方式,在此不再赘述。
在一个实施例中,如图33所示,该电动工具100中的储能装置109既给电机供电,还在一定条件下给把手120和电路板组件123来进行预热,并且第二储能装置104还给储能装置109来进行预热。温度检测装置117,用于检测环境 温度并发送给控制器106。
控制器106被设置为当温度检测装置117发送的温度小于等于第一预设温度且大于等于第二预设温度时,控制器106控制储能装置109给电路板组件123或把手120预热。
可选地,该电动工具100还包括:第二储能装置104,第二储能装置104给电机101供电,控制器106被设置为当温度检测装置117发送的温度小于等于第一预设温度且大于等于第二预设温度时,控制器106控制储能装置109给第二储能装置104预热,以提高电动工具100的性能。
在一实施例中,第一储能装置103和第二储能装置104与电池包耦合的方式,还可以通过检测环境温度,以使在第一储能装置103的工作温度下,电池包113通过电池包接口112与第一储能装置103耦合,以使在第二储能装置104的工作温度下,电池包113通过电池包接口112与第二储能装置104耦合。
在一实施例中,可以检测电动工具100的工作温度,来使得电池包接口112与哪个储能装置103耦合。当电池包接口112与第一储能装置103耦合时,电动工具100的工作温度大于等于第一预设温度,当电池包接口112与第二储能装置104耦合时,电动工具100的工作温度大于等于第二预设温度,第一预设温度大于第二预设温度。
可选地,当电池包接口112与第二储能装置104耦合时,电动工具100的工作温度大于或等于-40℃且小于或等于85℃。
可选地,当电池包接口112与第一储能装置103耦合时,电动工具100的工作温度大于或等于-20℃且小于或等于70℃。
可以理解的是,第一储能装置103和第二储能装置104两者不同,举例来说,第一储能装置103可以为三元锂电池或者磷酸铁锂电池,第二储能装置104可以为电容电池,这几种电池最佳的工作温度范围均是不同的,进而,在电动工具100工作在不同温度范围下,可以选择与不同的储能装置为其供电,以使得储能装置都能工作在最佳的工作温度区间内。需要说明的是,可以通过温度检测装置117检测电动工具100的工作温度,进而来控制电池包接口112与第一储能装置103耦合还是与第二储能装置104耦合。
在另一实施例中,可以通过检测储能装置本身的温度来选择哪个储能装置给电机101供电。如图34所示,该电动工具100,包括:控制器106,至少用于控制电源组件113对电机101的供电;
温度检测装置117,用于检测电源组件113的温度并发送给控制器106;
其中,当电源组件113的温度小于等于第一预设温度且大于等于第二预设 温度时,控制器106选择第二储能装置104对电机101进行供电。
也就是说,电源组件113可以给电机101供电,即可以选择第一储能装置103为电机101供电,也可以选择第二储能装置104为电机101供电,由于两个储能装置的工作温度范围不同,进而,当电源组件113的温度小于等于第一预设温度且大于等于第二预设温度时,说明,第二储能装置104适合对电机101进行供电,进而可以选择第二储能装置104对电机101进行供电。可以理解的是,可以在第二储能装置104与电机101的供电电路之间设置开关管,控制器106控制开关管的导通与关断,以控制第二储能装置104对电机101是否供电。
在一个实施例中,如图35所示,可以先执行S201检测环境温度,并且通过S202判断环境温度是否小于第二预设温度,若是则结束,若否,则通过S203检测第一储能装置的温度,接着通过S204判断第一储能装置的温度是否小于第一预设温度,若是,则通过S205开始第二储能装置预热电路板组件,以及预热第一储能装置,并实时检测第一储能装置的温度,当第一储能装置的温度大于第一预设温度时,结束预热。
综上所述,根据本申请实施例提出的电动工具,包括:机壳;电机,电机安装至机壳,机壳至少部分容纳电机;第一储能装置,为电机供电,第一储能装置包括至少一个第一储能单元;控制器,至少用于控制第一储能装置对电机的供电;温度检测装置,用于检测第一储能装置的温度并发送给控制器;电动工具还包括第二储能装置,第二储能装置包括至少一个第二储能单元,当第一储能装置的温度小于等于第一预设温度且大于等于第二预设温度时,控制器控制第二储能装置给第一储能装置预热。由此,当电动工具在低温环境作业时,第二储能装置可以给第一储能装置预热,从而使得第一储能装置可以在低温环境下先预热,再给电动工具的电机供电,避免第一储能装置在低温下出现电压不足,不能正常给电机供电的问题。
以上显示和描述了本申请的基本原理、主要特征和优点。本行业的技术人员应该了解,上述实施例不以任何形式限制本申请,凡采用等同替换或等效变换的方式所获得的技术方案,均落在本申请的保护范围内。
