具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
在第一实施例中，请参见图1，本申请提供一种充电装置，包括：电能输入接口110、第一电源线120、充电模块130及电能输出接口150。充电模块130包括输入端和输出端。电能输入接口150，可拆卸地与外部能源设备连接。第一电源线120的一端连接电能输入接口150，另一端连接充电模块130的输入端。充电模块130的输出端连接电能输出接口，电能输出接口可拆卸地与能量存储装置连接。
示例地，外部能源设备包括充电宝、大功率的可移动充电设备、电动汽车专用充电装置等。电动汽车专用充电装置如充电桩或者能量墙等。
其中，充电桩可以固定在地面或墙壁，安装于公共建筑(公共楼宇、商场、公共停车场等)和居民小区停车场或充电站内，可以根据不同的电压等级为各种型号的电动交通工具或者电动工具充电。具体地，充电桩可以设置有充电枪，充电枪通过电源线与充电桩连接，用于连接至待充电的充电汽车。充电桩的输入端与交流电网直接连接，充电枪的输出端安装有充电插头，用于连接至电动 交通工具或者电动工具充电。充电桩的功能类似于加油站里面的加油机。
能量墙(Power Wall Battery)包括存储能量的可充电的锂电池和控制系统。能量墙可以在电力需求低谷的时候低价充电，在电价更高的需求高峰时段输出电能。能量墙还可以存储过剩的太阳能发电，以便在没有太阳的时候使用。能量墙也可以在断电的时候提供电力保障。总之，能量墙可以实现转移负荷、电力备份以及太阳能发电自给。
在第二个实施例中，请参见图2，本申请还提供一种充电装置，包括：电能输入接口110、第一电源线120、充电模块130、第二电源线140及与电池包对应的电能输出接口150。其中，电能输入接口110，可拆卸地与外部能源设备连接。充电模块130包括输入端和输出端，充电模块130的输入端与第一电源线120的一端连接，充电模块130的输出端与第二电源线140的一端连接。第一电源线120的一端连接充电模块130的输入端，另一端连接电能输入接口110。第二电源线140的一端连接电能输出接口150，另一端连接充电模块130的输出端。电能输出接口150，可拆卸与能量存储装置连接。
以下结合图3对本发明第二实施例的第一种应用场景进一步介绍。能量墙210设置有插口，电能输入接口110连接能量墙210上的插口。电能输出接口150连接能量存储装置220上对应的插口。能量墙210、电能输入接口110、第一电源线120、充电模块130、第二电源线140、电能输出接口150和电池包220成形充电回路，电池包开始充电。
以下结合图3对本发明第二实施例的第二种应用场景进一步介绍。充电桩310设置有插口，电能输入接口110连接充电桩310上的插口。电能输出接口150连接能量存储装置220上对应的插口。充电桩310、电能输入接口110、第一电源线120、充电模块130、第二电源线140、电能输出接口150和电池包220成形充电回路，电池包220开始充电。可以理解的是，电能输入接口110还可以与充电桩310的充电枪(图中未示出)进行匹配连接。这样在不改变现有充电桩的结构前提下，扩展了充电桩的应用途径。
充电模块130可以是电压转换电路，比如BUCK电路或者RC电路。充电装置通过充电模块130将能量墙210或者充电桩310输出的高电压转换成与电 池包220匹配的电压。
在本实施例中，由于能量墙210或者充电桩310输出的电压较高，比如200至500V，甚至是300-750V，所以第一电源线可以是耐高压的电源线。充电装置与电池包220接口之间的连接可以采用普通电源线，即第二电源线可以是普通电源线。
上述实施例中，充电装置包括电能输入接口、第一电源线、充电模块、第二电源线及与电池包对应的电能输出接口。该充电装置通过电能输入接口可拆卸地与充电桩或者能量墙上的插口进行连接，与第一电源线、充电模块、第二电源线、电能输出接口以及能量存储装置构成充电回路，实现了利用能量墙或者充电桩给电动工具用的能量存储装置充电，使得能量墙或者充电桩得到充分利用，而且使得电动工具用的能量存储装置可以通过多种方式进行充电，使充电更加方便。
请继续参见图5为本发明提供的第三实施例，与第二实施例的区别在于，充电装置进一步设有与能量墙210或充电桩310之间进行信息交互的通信模块410，与充电模块130的输入端连接。具体地，当电能输入接口110连接于能量墙210或充电桩310上的插座且电能输出接口150连接于能量存储装置220时，充电装置通过通信模块410与能量墙210或充电桩310建立通信连接，两者通过第一电源线120交互信息，比如充电装置的型号、输出电流、电压以及与充电适配连接的能量存储装置的信息等。
上述实施例中，充电装置设置有通信模块，在开始充电前，可以与充电桩或能量墙建立通信进行信息交互。在通信建立后，能量墙210或充电桩310才会启动向外输出电能。
图6为本发明提供的第四实施例，与第三实施例的区别在于，充电装置进一步设有检测模块510，可以检测能量存储装置的特性信息。以能量存储装置为电动工具用电池包为例。检测模块510可以通过检测电池包中的识别电阻上的电压以识别电池包的种类。检测模块510与充电模块130的输出口通过第二电源线140连接，检测模块510可以识别电池包220的种类。具体地，请参见图7，电池包220设置有识别电阻R1，充电装置内设置有分压电阻R2和开关K1。检 测模块510连接于分压电阻R2与识别电阻R1的连接点。当充电能输入接口120连接于能量墙210或充电桩310上的插座且电能输出接口150连接于电池包的插口时，检测模块510可以通过识别电池包220的种类以获取电池包220的充电电压等相关信息。
请参见图8为本发明提供的第五实施例，与第四实施例的区别在于，充电装置进一步设有控制模块710，控制模块710的输入端与检测模块510连接，控制模块710的输出端与充电模块130的输入端连接。控制模块710可以调节充电模块130输出的电压和电流。具体地，检测模块510可以检测到与电能输出接口150连接的电池包220的相关信息。其中，检测模块510可以识别电池包的种类，也可以检测与该充电装置连接的电池包的数量，还可以检测电池包的充电电压。比如充电装置可以通过检测模块510检测到电池包的充电电压以进行充电电流的控制，以一个20V的电池包为例进行说明。当检测到电池包220的电压为10V≤U≤13V时，控制模块710通过控制充电模块130对电池包220进入涓流充电，充电电流为400mA±40mA；当电池包220的电压13V≤U≤20V时，充电电流为2.0A±0.2A；检测到电池包电压≥20V时，对电池包220进行恒压充电，充电电流会减小，充电继续。当充电时间达到预定时间时，充电装置停止对电池包220的充电。
第六实施例，请参见图9，与第五实施例的区别在于，充电装置进一步设有开关810，开关810的第一端连接控制模块710，开关810的第二端连接电能输入接口110，开关810的第三端连接电能输出接口150。
其中，开关710可以为金属-氧化物-半导体场效应管(MOSFET)，MOSFET的漏极连接电能输入接口110，MOSFET的源极连接电能输出接口150，而MOSFET的栅极与控制模块710连接，控制模块710改变施加在栅极的电压来改变电能输入接口110和电能输出接口150之间的开闭。开关还可以为晶闸管、晶体管、可控硅、继电器等。
本实施例中，检测模块510还包括用于实时检测电池包220的电量和温度的采集单元，控制模块710还包括用于根据电池包220的电量和温度控制开关710的闭合的判断单元。具体地，充电装置可以通过采集单元检测到电池包的温 度，并将该温度反馈给控制模块710，控制模块710内预存有电池包220充电温度范围，该温度范围为从同一类型的电池包的充电最低温度阈值到充电最高温度阈值，判断单元可以将检测到的充电电池包的温度与充电最低温度阈值及充电最高温度阈值进行比较以判断开关810是否需要断开或者闭合。
具体地，当电池包220低于充电最低温度阈值或超过充电最高温度阈值时，会影响到电池包220的性能，带来不必要的损失。在电池包充电过程中，检测到的电池包220的温度超过充电温度范围，控制模块710控制开关810断开，等待电池包220恢复温度，直至温度处于电池包220的充电温度范围，控制模块710控制开关810闭合，重新开始给电池包220充电。充电装置还可以通过检测模块510检测到电池包的电量，并将该电量反馈给控制模块710，控制模块710根据检测模块510反馈的电量控制开关810的断开或者闭合。
上述实施例中，充电装置设置有检测模块，在开始充电前，充电装置对电池包的信息进行检测，与充电桩或能量墙进行信息交互，以使能量墙210或充电桩310向电池包提供合理的充电电压和电流，使得电池包的充电行为更加安全，并减小对电池包的损害。
本实施例中，请参见图10，电能输出接口150包括温度检测插孔910、识别采样输入插孔920、识别低电压供电输出插孔930、充电输出插孔940。其中，充电输出插孔940包括正极941和负极942。具体地，温度检测插孔910与检测模块710的输入端连接，识别采样输入插孔920与检测模块510的输入端连接，识别低电压供电输出插孔930与检测模块510的输入端连接，充电输出插孔940的正极951和负极952分别与充电模块130的输出端连接。
在第七实施例中，充电装置可以为前述任一实施例中的充电装置，需要进一步说明的是电能输入接口110的具体设置。请参见图11，电能输入接口110包括通信插针S+及插针S-、确认充电连接的插针C1及插针C2、直流电源插针DC+及插针DC-、低电压辅助供电插针A+及插针A-、设备地插针GND。其中，插针S+及插针S-，用于在充电装置与能量墙210或充电桩310之间传输充电信息或者检测信息。插针C1及插针C2，用于确认充电装置与能量墙210或充电桩310之间的连接是否可靠。插针DC+及插针DC-，用于向充电模块130输入 直流。插针A+及插针A-，用于对充电模块130进行低电压辅助供电。插针GND用于与连接设备地。
在第八实施例中，请参见图12，第二电源线包括至少一条。检测模块510可以识别连接在能量存储装置的个数。控制模块710可以根据检测模块510检测到的电池包的个数调节充电模块130输出的电压和电流。
每条第二电源线连接一个电能输出接口150。每个电能输出接口150均能为一个能量存储装置220充电。因此，充电装置可以同时连接为多个能量存储装置220，并为其充电。
外部能源设备可能输出交流电，也可能输出直流电，可能输出高压，也可能输出低压。同一种输出电源的情况下每种外部能源设备的输出接口形式也不尽相同。为适应外部能源设备接口定义的不同，电能输入接口110需要不同的设置。
在如图13所示的第十实施例中，充电装置包括：电能输入接口110、识别模块122、充电模块130、电能输出接口150、控制模块710。电能输入接口110可拆卸地与至少两种外部能源设备连接，不同的外部能源设备向电能输入接口110提供不同的电源输入。识别模块122识别从所述电能输入接口110输入的电源类型，并生成相应的信号传递给控制模块710。充电模块130收容在所述充电装置的壳体中，将来自电能输入接口110的电能转换为适合为能量存储装置220充电的电能，并传递给能量输出接口150。控制模块710根据识别模块122的信号，调节充电模块输出的电压和电流。电能输出接口150与能量存储装置220可拆卸地连接，接收充电模块130输出的电能为能量存储装置220充电。能量存储装置220可选择地与电动工具连接，电动工具包括马达，能量存储装置220为所述马达供电。
考虑到电能输入接口110输入的电源可能为AC电源，可能为DC电源可能为高压，可能为低压。基于此，在一种可选的实施例中，充电模块130包括AC/DC模块、DC/DC升压模块、以及DC/DC降压模块。控制模块710根据识别模块122的信号，控制所述AC/DC模块、DC/DC升压模块、以及DC/DC降压模块中的至少一个工作，使得充电电路130能将电能输入接口110的输入电压转换 为适合给能量存储装置220充电的电压。
例如，在外部能源设备为充电桩或能量墙的情况下，当所述识别模块122识别到输入的电源为AC电源后，控制模块710根据识别模块122的信号控制所述AC电源经AC/DC模块、以及DC/DC降压模块后输出合适的充电电压给电能输出接口150。当识别模块122识别到输入的电源为DC电源后，控制模块710根据别模块122的信号控制所述DC电源经DC/DC降压模块后输出合适的充电电压给所述电能输出接口。
此外，充电宝的输出电压一般为4.7～5.2V。而电动工具的能量存储装置的电压一般为12V以上。在外部能源设备为充电宝时，识别模块122识别到输入的电源为4.7～5.2V的直流电源，控制模块510根据识别模块122的信号控制所述直流电源经DC/DC升压模块后输出合适的充电电压给电能输出接口150。
为使得充电装置能适配不同的外部能源设备，在一种可选的实施例中，充电装置包括至少第一种电能输入接口和第二种电能输入接口。第一种电能输入接口匹配第一种外部能源设备，第二种电能输入接口匹配第二种外部能源设备。第一种电能输入接口和第二种电能输入接口可拆卸与充电装置的壳体连接，且每次仅能连接其中一个。在另一种可选的实施例中，充电装置包括至少第一种电能输入接口和第二种电能输入接口。第一种电能输入接口匹配第一种外部能源设备，第二种电能输入接口匹配第二种外部能源设备。第一种电能输入接口和第二种电能输入接口可同时与充电装置的壳体连接。或两者均直接设置在充电装置的壳体上，或两者通过电缆与充电装置的壳体连接。
此外，不同的能量存储装置具有不同的充电电压以及不同的接口形态，为能给更多类型的能量存储装置220充电，电路模块和电能输出接口150需要不同的设置。
本发明还提供第十实施例，如图14所示。本实施例与第十实施例的差异在于，在第十一实施例中，充电装置还包括检测模块510。检测模块510能识别接入电能输出接口的能量存储装置的充电电压。识别的方式包括通信的方式或识别标识元件的方式。通信可以直接传递能量存储装置的充电电压或传递表征充电电压的其他参数。标识元件可以是标识电阻或IC标签等元件。控制模块710 根据识别模块122以及检测模块510的信号，控制AC/DC模块、DC/DC升压模块、以及DC/DC降压模块中的至少一个对输入的电源进行转换。以使得即使输入电源与能量存储装置的充电电压之间有不同的差异时，充电装置也能为其充电。
例如，在外部能源设备为充电桩或能量墙的情况下，当所述识别模块122识别到输入的电源为AC电源后，检测模块510进一步识别能量存储装置220的充电电压，控制模块710根据识别模块122及检测模块510的信号控制所述AC电源经AC/DC模块、以及DC/DC降压模块后输出合适的充电电压给电能输出接口150。当识别模块122识别到输入的电源为DC电源后，检测模块510进一步识别能量存储装置220的充电电压，控制模块710根据别模块122及检测模块510的信号控制所述DC电源经DC/DC降压模块后输出合适的充电电压给所述电能输出接口。
此外，充电宝的输出电压一般为4.7～5.2V。而电动工具的能量存储装置的电压一般为12V以上。在外部能源设备为充电宝时，识别模块122识别到输入的电源为4.7～5.2V的直流电源，同时检测模块510识别能量存储装置220的充电电压，控制模块510根据别模块122及检测模块510的信号控制所述直流电源经DC/DC升压模块后输出合适的充电电压给电能输出接口150。
为使得不同的能量存储装置220均能与充电装置连接，以进行充电，在一种可选的实施例中，充电装置包括至少第一种电能输出接口150和第二种电能输出接口150。第一种电能输出接口150匹配第一种能量存储装置220，第二种电能输出接口匹配第二种能量存储装置220。第一种电能输出接口150和第二种电能输出接口150可拆卸与充电装置的壳体连接，且每次仅能连接其中一个。在另一种可选的实施例中，充电装置包括至少第一种电能输出接口150和第二种电能输出接口150。第一种电能输出接口150匹配第一种能量存储装置220，第二种电能输出接口匹配第二种能量存储装置220。第一种电能输出接口150和第二种电能输出接口150可同时与充电装置的壳体连接。或两者均直接设置在充电装置的壳体上，或两者通过电缆与充电装置的壳体连接。
在第十一实施例中，充电装置与前述实施例的差别在于，电能输入接口110 和电能输出接口150均设置在收容充电电路的壳体上。未叙述的其他部分可选择的与前述任意一个实施例相同。

在第十三实施例中，电能输入接口110与壳体分离设置，第一电源线120的一端固定在壳体上，且连接充电模块130的输入端，第一电源线120的另一端远离壳体，且连接电能输入接口110。电能输出接口150与壳体分离设置，第二电源线140的一端固定在壳体上，且连接充电模块130的输出端，第二电源线140的另一端远离壳体，且连接电能输出接口150。未叙述的其他部分可选择的与前述任意一个实施例相同。
如前所述，给电动汽车充电的专用充电设备，如能量墙210或充电桩310的输出电压超过200V，属于高压。当能量存储装置220的电压低于100V时，需要将专用充电设备的输出电压降低50％以上，才能给能量存储装置220充电。为了能更高效地利用专用设备的输出电能，减少降压过程中的损耗，提高专用充电设备的利用率，优选的，能量存储装置的充电电压高于100V。
