请参阅图19至图21，本发明揭示了一种充电装置10，包括：壳体100、若干个充电槽101、散热结构200、以及充电模块210；其中，散热结构200包括散热组件；当充电槽101内***有电池包时，充电模块210与***的电池包通信连接，获取各电池包的第一温度，并根据第一温度对电池包进行充电。充电模块210上设置有至少一个温度传感器，各温度传感器将获取的充电模块210的第二温度传输至充电模块210，充电模块210还用于根据第一温度和/或第二温度生成控制信号，并将该控制信号输出至散热组件，控制散热组件的启动或关闭，从而将电池包在充电过程中产生的热量被快速有效地散出至壳体100外。应理解，本发明中涉及的电池包具有通信功能，且各电池包均设有BMS电池管理***，该BMS电池管理***可获取电池包的电流、电压及温度参数，并实时通信传输至充电模块210。此外，充电模块210包括具有通信功能的处理芯片及***电路，可根据预先存入的程序执行相应的步骤。
以下对充电装置10的结构及工作原理进行详细说明：
充电槽101，并排设置于壳体100的内部，用于容纳***的电池包。在本发明一实施方式中，充电槽101的个数被配置为6个，可同时容纳6个电池包；相应的，充电装置10配置有多个充电模块210，且每个充电模块210最多与两个电池包通信连接，并根据获取的各电池包的第一温度，对最多两个电池包进行充电，六个电池包可通过三个充电模块210进行充电控制。
进一步说明，当充电模块210同时为两个电池包进行充电时，若两个电池包的电量差小于预设电量，即两个电池包的电量相差较小或相同，则平均分配充电功率；若两个电池包的电量差大于预设电量，即两个电池包的电量相差较大，则优先为电量较大的电池包进行充电，为其分配更大的充电功率，例如2/3 的充电功率。
进一步说明，充电模块210获取电池包的第一温度后，根据温度范围调整相应的充电电流，从而控制不同温度条件下的充电功率，具体的说，充电模块210根据第一温度对各电池包进行充电包括：
当第一温度大于低温阈值，开始充电；
当第一温度升高到第一温度区间，采用第一电流进行充电；
当第一温度升高到第二温度区间，采用第二电流进行充电；
当任一电池包的第一温度上升到第一高温阈值，维持当前充电总功率不变，并采用第一电流对该电池包进行充电；
当任一电池包的第一温度上升到第二高温阈值，停止充电并报警。
应理解，温度过低或过高都会影响电池包性能，在低温或高温下对电池包充电，会对电池包造成损伤，缩短电池包的使用寿命，具体到本实施例中：
设定低温阈值为0度，当第一温度低于0度，不进行充电。
设定第一温度区间为0-5度，在此区间内，采用第一电流进行充电，该第一电流可根据需要自行设定，本实施例中的第一电流最大不超过2A，此时，若单个电池包的额定电压为80V，两个电池包的充电电流分别为1A，单个充电模块210的充电功率最大为80*2＝160W，三个充电模块210的充电总功率最大为480W。
设定第二温度区间为5-45度，在此区间内，采用第二电流进行充电，本实施例中的第二电流为6A，此时，两个电池包的充电电流分别为3A，单个充电模块210的充电功率最大为80*6＝480W，三个充电模块210的充电总功率最大为1440W。
设定第一高温阈值为45度，当任一电池包的第一温度达到45度，在维持当前充电总功率不变的前提下，采用小电流对该电池包进行充电，同时采用更多的充电电流为温度正常的电池包充电；本实施例中，采用第一电流，例如2A为温度较高的电池包充电，采用4A为温度正常的电池包充电；此时，单个充电 模块210的充电功率最大为80*(2+4)＝480W，三个充电模块210的充电总功率最大为1440W。直到电池包的第一温度降低到第二温度区间，再将每个电池包的充电电流配置为3A。
设定第二高温阈值为55度，当任一电池包的第一温度达到55度，为确保电池包的充电安全，应立即停止充电并报警，直到电池包的温度降低到正常范围，充电模块210再恢复充电。
继续说明，为了控制电池包充电时的上升温度，本发明的充电装置10包括散热结构200，用于将电池包在充电过程中产生的热量被快速有效地散出至壳体100外，其中：
散热结构200配置成为每个电池包散热，包括：进风口201、出风口202、通风口1120、第一气流发生装置1110、以及第二气流发生装置203；进风口201设置于壳体100上，供气流进入；出风口202设置于壳体100上，供气流流出；通风口1120对立的设置于壳体100上、并位于充电模块210的两侧。第一气流发生装置1110设置于壳体100内，并位于相邻两排相对立的两个充电槽101之间，进风口201流入的气流部分或全部在第一气流发生装置1110的驱动下，流经充电槽后被第一气流发生装置1110吸入，然后再被第一气流发生装置1110排出；第二气流发生装置203设置于壳体100内，并将第一气流发生装置1110排出的气流导出至出风口202外。充电槽101上设置有接电端子(未示出)，接电端子的一端与电池包上的电池包端子匹配，以实现与电池包电连接；接电端子的另一端电连接充电模块210。
请参阅图21，散热结构200的散热气流如图21所示，(其中，箭头表示气流的流向)，进风口201流入的气流部分或全部在第一气流发生装置1110的吸力下，流经充电槽101后被第一气流发生装置1110吸入，第二气流发生装置203设置于第一气流发生装置1110排出气流的第一流向1113或第二流向1114上，以将第一气流发生装置1110排出的气流导出至出风口202外，从而使得电池包在充电过程中产生的热量被快速有效地散出至壳体100外。
在本发明一实施方式中，第一气流发生装置1110导入的气流方向与其导出的气流方向垂直，且对同一排电池包进行散热的第一气流发生装置1110，其所导出的气流方向一致，对相邻两排电池包散热的第一气流发生装置1110所导出的气流方向相反。
请参阅图21，在本发明一实施方式中，第一气流发生装置1110包括：第一风扇安装座1111以及第一风扇1112，第一风扇安装座1111设置于壳体100的内部，并位于相邻两排相对立的充电槽101之间，第一风扇1112安装于第一风扇安装座1111上，第一风扇1112位于充电槽101的上方。第一风扇1112被配置成为单个电池包散热。
第一风扇安装座1111可拆卸安装于壳体100的内部，例如通过螺栓将第一风扇安装座1111安装于壳体100的内部。第一风扇安装座1111上设置有一个风扇进风口1115和一个风扇出风口1116。其中，风扇进风口1115布置在气流流入方向上，并朝向对应的充电槽101。因此，在第一风扇1112的驱动下，气流由进风口201进入、流经充电槽101后进入风扇进风口1115、并带走电池包产生的热量。
风扇出风口1116布置在第一风扇安装座1111的侧边水平方向上，且位于同一排的第一风扇安装座1111上的风扇出风口1116方向一致，相邻两排的第一风扇安装座1111上的风扇出风口1116方向相反。例如，相邻两排中的一排第一风扇安装座1111上的风扇出风口1116朝向与第一流向1113相同，另一排第一风扇安装座1111上的风扇出风口1116朝向与第二流向1114相同，第一流向1113与第二流向1114互为反方向。
因此，相邻两排的第一风扇安装座1111上的风扇进风口1115的朝向相反，且风扇出风口1116的朝向亦相反，即用于冷却相邻两排电池包的气流方向是相反的，从而形成了两个气流通路，每一气流被相应的出风口202导出壳体100外部，因此有效地避免了热量堆积，提高了冷却效率。
请参阅图22，在本发明一实施方式中，充电装置10的内壁上设置有安装 窗口102，第一风扇安装座1111位于安装窗口102内。电池包上设置有相对应的第一散热孔与第二散热孔，第一风扇安装座1111对应的设置有风扇进风口1115和风扇出风口1116，风扇进风口1115的位置与第一风扇1112相对应。进风口201流入的气流部分或全部流经第一散热孔、第二散热孔进入第一风扇安装座1111上的风扇进风口1115，并经由第一风扇1112吸入后，再从风扇出风口1116排出。
请参阅图19及图21，在本发明一实施方式中，充电槽101的个数、第一风扇安装座1111的个数、以及第一风扇1112的个数相同，例如为6个。充电装置10设置有多个充电槽101，一次性可以给多个电池包同时充电，提高了的充电效率，同时每个充电槽101旁侧均设置有第一风扇1112，即每个电池包都有相应的第一风扇1112进行散热，因此具备了优良的散热效率。
在本发明一实施方式中，位于相邻两排相对立的两个充电槽101之间的两个第一风扇安装座1111相连接。位于相邻两排相对立的两个充电槽101之间的两个第一风扇安装座1111为一体成型结构，在另一实施方式中，两个第一风扇安装座1111不限于一体成型结构，也可选用分体式。
请参阅图21，在本发明一实施方式中，第一风扇1112为离心风扇。离心风扇具备通风效果好、噪音低等优点，能快速有效的将电池包在充电过程中产生的热量自入口吸入并自出口散出。
请参阅图21，在本发明一实施方式中，第二气流发生装置203包括：第二风扇，第二风扇分别设置于壳体100的两个端部，并位于壳体100的内侧。两个第二风扇的轴心位于壳体的横向中心轴线上。或者两个第二风扇的轴线位置与第一风扇安装座上的风扇出风口1116中心轴向重合。第二风扇将第一风扇1112排出的热气流进一步的排出至壳体100的外部，从而使得电池包的热量自产生处至壳外之间形成一个完整的散热通路，不会发生热量滞留聚积的情况，进而保证了优良的散热效率。
在本发明一实施方式中，第二风扇为轴流风扇。轴流风扇具备结构简单、 便于安装、通风效果好、噪音低等优点。
请参阅图21及图23，在本发明一实施方式中，出风口202由若干个相互平行的倾斜筋排列而成，倾斜筋的倾斜角度为：35度-55度。倾斜角度指的是倾斜筋自水平面向下倾斜的角度α，其中角度α为35度-55度或者自垂直面向外倾斜角度β，角度β与角度α之和为90度。该倾斜角度利于散热。出风口202安装于壳体100上，并位于第二风扇的旁侧，出风口202的个数与第二风扇的个数相同。
请参阅图24，在本发明一实施方式中，充电模块210安装于壳体100的内部，充电模块210与充电槽101内的接电端子电连接，散热结构200还包括第三气流发生装置204，第三气流发生装置204安装于通风口1120与充电模块210之间，气流自其中一侧的通风口1120被第三气流发生装置204导入、再被第三气流发生装置204自另一侧的通风口1120导出。图24中的箭头表示气流的流向。
请参阅图24，在本发明一实施方式中，通风口1120包括第一通风窗1121以及第二通风窗1122，第一通风窗1121与第二通风窗1122相对设立，第一通风窗1121进入的气流部分或全部被第三气流发生装置204吸入并自第二通风窗1122排出。第一通风窗1121或第二通风窗1122由若干个相互平行的倾斜筋排列而成，倾斜筋的倾斜角度为：35度-55度。倾斜角度指的是倾斜筋自水平面向下倾斜的角度或者自垂直面向外倾斜角度。该倾斜角度利于散热。
请参阅图24，在本发明一实施方式中，为避免后期使用时单个充电模块210出现问题导致整个电路无法使用，本实施例的充电装置10配置有多个充电模块210，相邻的两个充电模块210之间由隔板隔离。
第三气流发生装置204包括若干个第三风扇。每一充电模块210的两侧各设置一第三风扇，若干个第三风扇产生的气流的流向相同，且气流流向与隔板平行，具体地气流被充电模块210一侧的第三风扇自第一通风窗1121导入，并流向充电模块210另一侧对应的第三风扇，并被该第三风扇导出至第二通风窗 1122外。若干个充电模块210，其优点是便于后期的维护。例如某电路出现故障时，只需要更换该电路所处的充电模块210而不是更换全部充电模块210，从而降低了维修成本。在本发明一实施方式中，第三风扇可以为轴流风扇。
应理解，若干个第一风扇1112、若干个第二风扇及若干个第三风扇共同构成本方案的散热组件。
为方便对各区域进行分区控制及针对性散热，提高散热效率，同时也避免了散热不足以及过度散热的问题，采用多个充电模块210分别控制位于不同区域风扇的启动或关闭，且每个充电模块210最多控制两个风扇。此外，为方便整体控制风扇的启停，还设置有一个主控制模块，该主控制模块分别与每个充电模块210及每个第二风扇电连接，主控制模块用于获取所有充电模块210的充电总功率，并根据该充电总功率控制第二风扇的启动或关闭。应理解，主控制模块包括处理芯片及***电路，且各充电模块210及主控制模块通过大功率的开关管驱动各风扇。
请参阅图25，图25中充电装置10容纳的电池包的数量为6个，配置有3个充电模块210，各充电模块210的标号分别为充电模块a、充电模块b及充电模块c；相应的，第一风扇1112配置有六个、第二风扇配置有两个、第三风扇配置有六个，以下以充电模块a及主控制模块为例，对各风扇的控制逻辑进行说明：
针对第一风扇1112，每个第一风扇1112配置于一个电池包的一侧，电池包1和/或电池包2***充电槽101后，分别与充电模块a建立通信连接，并将电池包1和/或电池包2的第一温度实时传输至充电模块a，若充电模块a在充电过程中检测到任一电池包的第一温度大于第二高温阈值，立即停止充电，同时输出控制信号到该电池包对应的第一风扇1112，启动该第一风扇1112，对该电池包进行降温处理，直到电池包的第一温度降低到正常温度，才允许电池包继续充电。进一步的，在开始充电前，若充电模块a检测到任一电池包的温度大于第二高温阈值，则立即开启该电池包对应的第一风扇1112对其进行降温， 直到该电池包的第一温度降低到正常温度，才允许电池包开始充电。
针对第三风扇，充电模块a根据温度传感器获取的第二温度，实时检测充电模块a的工作温度，当该工作温度超出预设温度，例如95度，充电模块a输出控制信号到第三风扇1和第三风扇2，开启第三风扇1和第三风扇2，对充电模块a进行降温处理。
针对第二风扇，主控制模块获取各充电模块210的充电功率，计算得到充电过程中的充电总功率，当充电总功率大于预设功率小于第一预设功率，主控制模块输出控制信号到一个第二风扇，开启该第二风扇；当充电总功率大于第一预设功率小于第二预设功率，主控制模块输出控制信号到两个第二风扇，开启两个第二风扇从而将第一风扇1112排出的热气流进一步的排出至壳体100的外部。进一步的，主控制模块还与各充电模块210实时进行数据交互，在特定状况下，例如任一电池包的第一温度达到55度，此时主控制模块可分别发送控制信号到各充电模块210及第二风扇，同时开启所有的第一风扇、第二风扇及第三风扇，以便将壳体100内的热气流排出，快速降低壳体内部的温度。
需要说明的是，上述各风扇的启动温度、预设功率、第一预设功率及第二预设功率均可根据实际需要自行设定，本方案不对具体数据进行限定。
应理解，充电模块210b、充电模块210c的控制逻辑与充电模块210a相同，为节省篇幅，不再赘述。
请参阅图20，在本发明一实施方式中，进风口201由若干个相互平行的倾斜筋排列而成。倾斜筋的倾斜角度为：35度-55度。倾斜角度指的是倾斜筋自水平面向下倾斜的角度或者自垂直面向外倾斜角度。该倾斜角度利于散热。
本发明中的进风口201、出风口202、第一通风窗1121、以及第二通风窗1122除上述实施方式中的倾斜筋结构外，还可以为其他的能够流通气流的结构，例如为通孔或缝隙等。
可见，本实施方式的一种充电装置，可实时检测电池包充电时的第一温度，并根据第一温度的范围调整充电电流，有效提高了电池包的充电效率；同时， 还实时检测充电模块210的第二温度，以及所有电池包的充电总功率，当第一温度、第二温度或充电总功率超出预设范围，及时开启对应位置的风扇，将电池包在充电过程中产生的热量快速有效地散出至壳体外，延长了电池包的使用寿命、实现了降低能耗和充电安全的和谐兼容。
