在本申请实施例中，进料腔与静置腔连接，当通过调压装置将进料腔内的 压力升至与静置腔内的压力相同时，进料腔密封闸门打开，电池单体通过输送装置由进料腔进入静置腔进行静置。电池单体在一个稳定的压力环境中静置，具有良好的一致性，能够保证电池单体的性能。将进料腔的压力升至静置腔的压力后，再将电池单体移入静置腔，这样，在将电池单体从进料腔输送至静置腔的过程中，静置腔内的压力不会发生改变，从而也就不需要向静置腔额外补充压力，可以减少静置设备的能耗。因此，本申请实施例的技术方案可以在保证电池单体的性能的同时降低静置设备的能耗。
在一种可能的实现方式中，所述进料腔密封闸门被配置为当所述电池单体输送至所述静置腔后关闭，所述进料腔被配置为在所述进料腔密封闸门关闭后降压；所述静置设备还包括：进料密封盖，所述进料密封盖设置于所述进料腔背离所述静置腔的一端，所述进料密封盖被配置在所述进料腔内的压力降压后打开，以放入所述电池单体。这样，可以保证静置腔和进料腔之间的密封性，防止进料腔在降压过程中由于密封不足导致的静置腔内的压力的降低，从而可以维持静置腔内的压力，防止静置腔内压力改变而需要额外提供能量维持静置腔内的压力。在进料腔内的压力降低后，进料腔内与静置设备外的压力差较小，方便进料密封盖的打开。
在一种可能的实现方式中，所述静置设备还包括：出料腔，与所述静置腔的第二端连接，所述出料腔与所述调压装置连接；出料腔密封闸门，设置于所述静置腔和所述出料腔之间，所述出料腔密封闸门被配置为在所述出料腔内的压力升至所述静置腔内的压力时打开，以将所述电池单体输送至所述出料腔。这样，在将电池单体从静置腔输送至出料腔的过程中，静置腔内的压力不会发生改变，从而也就不需要向静置腔额外补充压力，可以减少静置设备的能耗；同时，在电池单体在静置腔完成静置后，只需在出料腔内的压力与静置腔内的压力相等时，将电池单体从静置腔输送至出料腔，关闭出料腔密封闸门，再将电池单体从出料腔移出即可，不需要在排出静置腔内的高压后才将电池单体从静置腔内移出，从而进一步减少了静置设备的能耗。
在一种可能的实现方式中，所述出料腔密封闸门被配置为当所述电池单体输送至所述出料腔后关闭，所述出料腔被配置为在所述出料腔密封闸门关闭后降压；所述静置设备还包括：出料密封盖，所述出料密封盖设置于所述出料腔背离所述静置腔的一端，所述出料密封盖被配置为在所述出料腔内的压力降压后打开，以移出所述电池单体。这样，可以保证静置腔和出料腔之间的密封性，防止出料腔在降压过程中 由于密封不足导致的静置腔内的压力的降低，从而可以维持静置腔内的压力，防止静置腔内压力改变而需要额外提供能量维持静置腔内的压力。在出料腔内的压力降低后，出料腔内与静置设备外的压力差较小，方便出料密封盖的打开。

在一种可能的实现方式中，所述输送装置包括第一子输送装置和第二子输送装置，所述第一子输送装置和所述第二子输送装置分别穿设于所述进料腔和所述静置腔内，其中，所述第一子输送装置和所述第二子输送装置之间间隔设置，以避让所述闸门板。第一子输送装置和第二子输送装置之间间隔设置，也即，二者是分离设置的，这样闸门板可以设置在间隙处，从而输送装置可以实现对闸门板的避让，保证闸门板与第一开口之间的密封。
在一种可能的实现方式中，所述静置腔的容积为所述进料腔的容积的1～20倍。这样，相比于静置腔，进料腔由于容积更小所以升压速度更快，同时升压消耗的能量也更少，即可以加快生产效率也可以减少能耗；同时，由于电池单体的静置时间较长，增加静置腔的容积可以增加电池单体的静置数量，加快生产效率。
在一种可能的实现方式中，所述静置腔为分段式结构。这样，可以根据实际需要设置静置腔的段数，通过增加静置腔的段数增加静置的电池单体的数量；同时由于静置腔的容积与静置腔的段数有关，可以根据电池单体所需的静置时间灵活设置 静置腔的段数。此外，每段静置腔的大小相同时，还可以实现静置腔的以换代修，避免了静置腔的故障造成的生产暂停，有利于提升生产效率。
在一种可能的实现方式中，所述进料腔和所述静置腔的形状为圆柱形。这样，进料腔和静置腔内受力均匀，相比于方形的进料腔和静置腔，圆柱形的进料腔和静置腔满足强度前提下所需的厚度更小，有利于降低成本。

电池单体20可以包括锂离子二次电池、锂离子一次电池、锂硫电池、钠锂离子电池、钠离子电池或镁离子电池等，本申请实施例对此并不限定；电池单体20可以呈圆柱体、扁平体、长方体或其它形状，本申请实施例对此也不限定；电池单体20按封装的方式可以分为柱形电池单体、方体方形电池单体和软包电池单体，本申请实施例对此也不限定。
调压装置51是用于调节压力的设备。在一些实施例中，调压装置51可以用于调节静置设备50的压力，具体的，调压装置51可以通过第一管道511与进料腔501连接，用于调节进料腔501内的压力。可选地，调压装置51可以为空压机。
静置腔502用于静置电池单体20。在一些实施例中，在静置设备50运行前，静置腔502内的压力为P0，在静置设备50的初始运行阶段，调压装置51向静置腔502补压，以使静置腔502内的压力达到目标压力P1，其中，P1的数值可以根据实际需求进行调节，例如，P1可以为1.2MPa，P0可以为标准大气压。在静置设备50开始正式运行后，静置腔502内的压力维持为P1，此时，电池单体20可以在静置腔502内进行静置。由于静置腔502内的压力维持为P1，这样，电池单体20在稳定的压力下静置，可以保证每个电池单体20对电解液吸收的程度相同，有利于提升电池或电池单体10的一致性。
进料腔501与静置腔502的第一端连接，第一端可以为静置腔502沿电池单体20的输送方向靠近进料腔501的一端。
图3为本申请一些实施例中的输送装置的结构示意图。结合图2和图3所示，输送装置505贯穿设置于进料腔501和静置腔502之间，可以用于输送电池单体20。可选地，输送装置505可以为沿x方向延伸的辊筒形传送装置，即，输送装置505由多个辊筒形的单元组成。
在本申请实施例中，进料腔501与静置腔502连接，当通过调压装置51将进料腔501内的压力升至与静置腔502内的压力相同时，进料腔密封闸门5011打开， 电池单体20通过输送装置由进料腔501进入静置腔502进行静置。这样，电池单体20具有良好的一致性，能够保证电池单体20的性能。将进料腔501的压力升至静置腔502的压力后，再将电池单体20移入静置腔502，这样，在将电池单体20从进料腔501输送至静置腔502的过程中，静置腔502内的压力不会发生改变，从而也就不需要向静置腔502额外补充压力，可以减少静置设备50的能耗。因此，本申请实施例的技术方案可以在保证电池单体20的性能的同时减少静置设备50的能耗。
可选地，在本申请一些实施例中，进料腔密封闸门5011被配置为当电池单体20输送至静置腔502后关闭，进料腔501被配置为在进料腔密封闸门5011关闭后降压；静置设备50还包括：进料密封盖5012，进料密封盖5012设置于进料腔501背离静置腔502的一端，进料密封盖5012被配置在进料腔501内的压力降压后打开，以放入电池单体20。
电池单体20从进料腔501输送至静置腔502后，进料腔密封闸门5011关闭，进料腔501进行降压。这样，可以防止由于进料腔501和静置腔502之间的密封不足引起的静置腔502内的高压的泄漏，进而可以维持静置腔502内的压力，避免了额外向静置腔502补压所造成的能量损耗。
在进料腔密封闸门5011关闭后，进料腔501降压。其中，在一些实施例中，进料腔501可以在进料密封盖5012打开后继续降压，例如进料腔501内的部分高压在进料密封盖5012打开前排出，在进料密封盖5012打开后，进料腔501内的高压全部排出，进料腔501内的压力降为常压；在另一些实施例中，进料腔501可以设置有排气口，在进料腔密封闸门5011关闭后，进料腔501可以通过排气口将进料腔501中的高压全部排出，从而进料腔501内的压力降至常压，其中，进料腔501可以先通过其他装置排出进料腔501内的部分高压，然后再通过排气口排出剩余的高压，进料腔501也可以只通过排气口排出进料腔501内的全部高压直至进料腔501内的压力降为常压，本申请实施例对此不作具体限制。
进料密封盖5012用于在电池单体20进入进料腔501时打开，在电池单体20进入进料腔501后关闭，这样，方便对进料腔501进行升压。在进料腔501内的压力升至静置腔502内的压力时，进料腔密封闸门5011打开，电池单体20由进料腔501进入静置腔502，在电池单体20进入静置腔502后，进料腔密封闸门5011关闭。此时，在一些实施例中，进料腔501内的至少部分高压排出，进料密封盖5012打开，进料腔501 内的压力进一步降低至常压，在进料腔501内的压力降至常压后，放入下一组电池单体20以开始下一组电池单体20的静置；在另一些实施例中，进料腔501内的至少部分高压排出，进料腔501内剩余的高压通过排气口排出进料腔501，在进料腔501内的压力降至常压后，进料密封盖5012打开，放入下一组电池单体20以开始下一组电池单体20的静置。
可选地，在本申请一些实施例中，静置设备50还包括：出料腔503，与静置腔502的第二端连接，出料腔503与调压装置51连接；出料腔密封闸门5031，设置于静置腔502和出料腔503之间，出料腔密封闸门5031被配置为在出料腔503内的压力升至静置腔502内的压力时打开，以将电池单体20输送至出料腔503。
出料腔503与静置腔502的第二端连接，第二端可以为静置腔502沿电池单体20的输送方向的远离进料腔501的一端。
调压装置51还可以通过第二管道512与出料腔503连接，以调节出料腔503内的压力，例如，为出料腔503增压。
出料腔密封闸门5031设置于静置腔502和出料腔503之间，当出料腔503内的压力升至与静置腔502的压力相同时，出料腔密封闸门5031打开，以使电池单体20移出至静置腔502。这样，静置腔502内的压力与出料腔503内的压力相同，在出料腔密封闸门5031打开时，静置腔502内的压力不会发生改变。同时，在电池单体20静置完成后，只需将电池单体20从静置腔502输送至出料腔503，再关闭出料腔密封闸门5031后，从出料腔503移出电池单体20即可，不会改变静置腔502内的压力，可以保证静置腔502的压力始终处于一个稳定的状态，可以避免静置腔502压力降低后需要额外的能量来提高静置腔502的压力，从而进一步降低了能耗。
可选地，在本申请一些实施例中，出料腔密封闸门5031被配置为当电池单体20输送至出料腔503后关闭，出料腔503被配置为在出料腔密封闸门5031关闭后降压；静置设备50还包括：出料密封盖5032，出料密封盖5032设置于出料腔503背离静置腔502的一端，出料密封盖5032被配置为在出料腔503内的压力降压后打开，以移出电池单体20。这样，可以避免电池单体20从出料腔503中移出时，造成的静置腔502内的高压的泄漏。
电池单体20从静置腔502输送至出料腔503后，出料腔密封闸门5031关闭，出料腔503进行降压。这样，可以防止由于进出料腔503和静置腔502之间的密封 不足引起的静置腔502内的高压的泄漏，进而可以维持静置腔502内的压力，避免了额外向静置腔502补压所造成的能量损耗。
在出料腔密封闸门5031关闭后，出料腔503降压。其中，在一些实施例中，出料腔503的压力可以在出料密封盖5032打开后继续降压，例如出料腔503内的部分高压在出料密封盖5032打开前排出，在出料密封盖5032打开后，出料腔503内的高压全部排出，出料腔503内的压力降为常压；在另一些实施例中，出料腔503可以设置有出气口，在出料腔密封闸门5031关闭后，出料腔503可以通过出气口将出料腔503中的高压全部排出，从而出料腔503内的压力降至常压，其中，出料腔503可以先通过其他装置排出部分高压，再通过出气口排出剩余的高压，出料腔503也可以只通过出气口排出出料腔503内的全部高压直至出料腔503内的压力降至常压，本申请实施例对此不作具体限制。
出料密封盖5032被配置为在出料腔503内的压力降压后打开，此时，出料腔503内与静置设备50外的压力差较小或者出料腔503内的压力与静置设备50外的压力相同，方便出料密封盖5032的打开，出料密封盖5032打开后，静置完成的电池单体20从出料腔503移出。
可选地，在本申请一些实施例中，静置设备50还包括压力回收装置53。压力回收装置53分别与进料腔501和出料腔503连通，以将进料腔501和出料腔503一者中的高压回收到另一者中。
可选地，在电池单体20上料过程中，将电池单体20放入进料腔501后关闭进料密封盖5012，调压装置51将进料腔501的压力调至与静置腔502内的压力一致，此时进料腔密封闸门5011打开以将电池单体20输送至静置腔502内，压力回收装置53被配置为在电池单体20从进料腔501移动至静置腔502且进料腔密封闸门5011关闭后，将进料腔501的压力回收至出料腔503，以提高出料腔503内的压力，减小电池单体20从静置腔502移出至出料腔503时出料腔503升压所需要的能耗。一方面，通过压力回收装置53可以将进料腔501内的压力由P1降至P2后，便于进料密封盖5011打开，并放入下一组电池单体20以开始对下一组电池单体20的静置。另一方面，通过压力回收装置53可以将出料腔503内的压力由P0升至P2，此时调压装置51向出料腔503补压以使出料腔503内的压力与静置腔502内的压力相同时可以减小调压装置51的能耗。这样，实现了进料腔501内的高压的回收再利用，调压装置51不需要将出料腔 503从P0开始升压至P1，进一步减少了能耗。
可选地，在电池单体20出料过程中，调压装置51将出料腔503内的压力调至与静置腔502内的压力一致，此时出料腔密封闸门5031打开以将电池单体20输送至出料腔503内，压力回收装置53被配置为在电池单体20从静置腔502移动至出料腔503且出料腔密封闸门5031关闭后，将出料腔503的压力回收至进料腔501，以提高进料腔501内的压力，减小电池单体20从进料腔501输送至静置腔502时进料腔501升压所需要的能耗。一方面，通过压力回收装置53可以将出料腔503内的压力由P1降至P3后，便于出料密封盖5031打开，并将静置完成的电池单体20移出出料腔503。另一方面，通过压力回收装置53可以将进料腔501内的压力由P0升至P3，此时，调压装置51向进料腔501补压以使进料腔501内的压力与静置腔502内的压力相同时可以减小调压装置51的能耗。这样，实现了出料腔503内的高压的回收再利用，调压装置51不需要将进料腔501从P0开始升压至P1，进一步减少了能耗。
可选地，压力回收装置53可以为压力回收管道，压力回收管道设置有阀门，当阀门打开时，进料腔501内的高压可以通过压力回收管道进入出料腔503或者出料腔503内的高压可以通过压力回收管道进入进料腔501，实现了高压气体的回收再利用。压力回收管道的设置，可以实现进料腔501和出料腔503内的压力的自发的平衡，不需要额外的动力即可实现高压的回收再利用。

在一些实施例中，闸门体5011a可以包括相互连接的主体部5011e和凸起部5011d，凸起部5011d沿主体部5011e的径向凸出于主体部5011e，凸起部5011d用于在进料腔密封闸门5011打开时容纳闸门板5011b，以防止闸门板5011b上的灰尘造成闸门板5011b移动时卡顿或者影响闸门板5011b与第一开口5011c之间的密封性；主体部5011e的直径大于进料腔501和静置腔502的直径，闸门体5011a的主体部5011e套设 在进料腔501和静置腔502上，以连接进料腔501和静置腔502。当然在另一些实施例中，闸门体5011a的主体部5011e也可以通过螺栓连接、焊接等方式连接在进料腔501和静置腔502上。
闸门板5011b可移动设置于闸门体5011a，闸门板5011b可以沿闸门体5011a的主体部5011e的径向移动，以打开或关闭第一开口5011c。例如，在一些实施例中，闸门板5011b可以沿垂直于电池单体20的输送方向，即x方向相对于闸门体5011a移动，以打开或关闭第一开口5011c；在另一些实施例中，闸门板5011b可以沿竖直方向相对于闸门体5011a上下移动，例如，z方向，以打开或关闭第一开口5011c。
在一些实施例中，闸门板5011b可以与驱动装置连接，在驱动装置的驱动下，进料腔密封闸门5011打开时，闸门板5011b沿闸门体5011a的主体部5011e的径向移动并容纳在凸起部5011d中，以实现进料腔501和静置腔502的连通，电池单体20可以通过第一开口5011c进入静置腔502；进料腔密封闸门5011关闭时，闸门板5011b复位并可以完全封闭第一开口5011c，以实现进料腔501和静置腔502之间的密封。
可选地，闸门板5011b的尺寸可以大于或等于第一开口5011c的尺寸，其中，闸门板5011b可以为方形，圆形等形状，对应的，第一开口5011c也为方形，圆形等形状。
可选地，在本申请一实施例中，出料腔密封闸门5031包括出料腔闸门体和出料腔闸门板，该出料腔闸门体和出料腔闸门板可以具有与进料腔密封闸门5011的闸门体5011a和闸门板相同的结构，本申请实施例对此不作赘述。
可选地，在本申请一实施例中，输送装置505包括第一子输送装置5051和第二子输送装置5052，第一子输送装置5051和第二子输送装置5052分别穿设于进料腔501和静置腔502内，其中，第一子输送装置5051和第二子输送装置5052之间间隔设置，以避让闸门体5011a。第一子输送装置5051和第二子输送装置5052为分离设置的，也就是说，二者之间具有间隔，这样，可以在间隙处设置闸门板5011b，以使闸门板5011b可以密封第一开口5011c，从而实现了进料腔密封闸门5011的密封功能。因此，该第一子输送装置5051和第二子输送装置5052的间隔设置实现了对闸门体5011a的闸门板5011b的避让，能够保证闸门板5011b与第一开口5011c之间的密封。
可选地，输送装置505还包括第三子输送装置5053，第三子输送装置5053穿设于出料腔503，第二子输送装置5052和第三子输送装置5053之间间隔设置，以实 现对出料腔闸门体的避让，保证出料腔密封闸门5031的密封性。
可选地，静置设备50中的输送装置505可以为多层结构，例如，结合图5和图6所示，静置设备50中沿z方向包括2层输送装置505。通过设置输送装置505为多层，可以增加静置设备50中的静置的电池单体20的数量。
可选地，在本申请一些实施例中，静置腔502的容积为进料腔501的容积的1～20倍。一方面，相比于静置腔502，进料腔501由于容积更小所以升压到P1的速度更快，同时升压消耗的能量更少，既可以加快生产效率也可以减少能耗。另一方面，当电池单体20所需的静置时间较长时，增加静置腔502的容积可以是静置腔502容纳更多的电池单体20，加快生产效率。
可选地，在本申请一实施例中，静置腔502为分段式结构。例如，进料腔501的容积为V1，静置腔502的容积为n*V1，静置腔502和进料腔501具有相同的横截面积，其中，n为静置腔502的段数。这样，可以根据实际需要设置静置腔502的段数，当电池单体20所需的静置时间较短时，可以通过减少静置腔502的段数减少静置腔502的容积；当电池单体20所需的静置时间较长时，可以通过增加静置腔502的段数增加静置腔502的容积，从而满足了电池单体20对不同静置时间的需求。此外，当一段静置腔502出现故障时，由于各静置腔502的容积和横截面积相同，可以快速的替换为新的静置腔502，实现了以换代修，避免了静置腔502故障造成的生产暂停，有利于提升生产效率。
可选地，在本申请一实施例中，进料腔501和静置腔502的形状为圆柱形。这样，进料腔501和静置腔502内受力均匀，相比于方形的进料腔501和静置腔502，圆柱形的进料腔501和静置腔502满足强度前提下所需的厚度更小，有利于降低成本。
可选地，出料腔503的形状也为圆柱形，也就是说，静置设备50的整个腔体均为圆柱形。
可选地，静置设备50水平放置，这样，静置设备50可以节省在高度方向上的空间。同时，相比于竖直设置，输送装置输送电池单体20的能耗也可以进一步减少。
图7为本申请一些实施例的托盘夹具的示意图。可选地，如图7所示，在本申请一些实施例中，静置设备50还包括托盘夹具60，托盘夹具60设置于输送装置505上，用于放置电池单体20。通过将电池单体20放置在托盘夹具60，托盘夹具60放置在输送装置505上，实现对电池单体20在静置设备50中的移动，也就是说，托盘夹具 60的设置便于电池单体20的输送与搬运。
图8为图7中区域A的放大示意图。可选地，在本申请一些实施例中，结合图7和图8所示，托盘夹具60包括注液机构61和注液夹具62。注液机构61的排液口610被配置为对准电池单体20的注液口210，以向电池单体20注入电解液。注液夹具62用于夹持电池单体。这样，在电池单体20的静置过程中，注液机构61还可以向电池单体20注入电解液，从而可以提高电池单体20内部的电解液的含量。
可选地，托盘夹具60还可以包括安装架600，安装架600包括第一托盘63，第二托盘64，连接第一托盘63和第二托盘64的支架65，以及第一托盘加强筋631。第一托盘63设置有用于承载注液机构61的安装孔，第一托盘加强筋631用于增强第一托盘63的结构强度。第二托盘64用于承载电池单体20，注液夹具62用于夹持并固定电池单体20。通过安装架600的设置，注液机构61和电池单体20可以固定在安装架600上从而形成一个整体，便于搬运和输送。
可选地，注液夹具62用于夹持固定电池单体20，一组电池单体20可以通过相对设置的一对注液夹具62实现夹持固定。
注液机构61可以包括多个电解液缓存杯，其中每个电解液缓存杯为对应的电池单体20注液，电解液缓存杯中的电解液可以经由排液口610进入注液口210。可选地，电池单体20在进入静置设备50前，可以通过注液机构61向电池单体20注入电解液缓存杯中30％～50％的电解液，剩余的电解液可以在电池单体20在静置设备50静置的过程中逐渐注入。这样，电池单体20在压力的作用下吸收电解液的同时继续向电池单体20注入电解液，有利于提高电池单体20对电解液的吸收程度，进而增加电池单体20中的电解液的含量。
可选地，在本申请一些实施例中，如图8所示，排液口610靠近注液口210一端设置有密封件611。例如，密封件611可以为橡胶密封圈。这样，可以防止电解液从排液口610和注液口210的连接处泄露。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
