请参阅图1，本申请实施方式提供一种调节电路100。调节电路100与多个并联的电芯(例如图1示意的电芯B1、电芯B2)连接，且与充放电电路200连接。其中，多个电芯的数量可以是2个、3个、4个、5个或更多个，在此不一一列举。充放电电路200与调节电路100连接，可以将外部电源的电量输入电芯，也可以将电芯的电量输出至用电元件、用电装置、用电设备等。调节电路100能够调节电芯与充放电电路200之间的电流值， 以及调节电芯与电芯之间的电流值，以确保电芯的充放电安全、发挥电芯的最佳性能。
请参阅图1，调节电路100包括：多个开关模组10、控制模块20及采样模块30。每个开关模组10与一个电芯对应，开关模组10连接电芯及充放电电路200。控制模块20与多个开关模组10连接，控制模块20存储有预设的均衡参数，均衡参数包括电芯的电压值与均衡电流的对应关系。采样模块30与控制模块20连接，用于获取每个电芯的电压值。其中，控制模块20根据每个电芯的电压值及均衡参数调节流经开关模组10的电流的电流值，以使多个电芯之间的电流值达到均衡电流。
其中，均衡电流是一个电芯(例如B1)向另一电芯(例如B2)提供电流时的预设电流值。均衡电流的取值需要结合电芯的电压值及预设的均衡参数确定。在电芯的电压值发生变化时，采样模块30能够获取变化后的电压值，控制模块20能够根据变化后的电压值和均衡参数获取对应的均衡电流，若电芯的电压值变化前后所对应的均衡电流发生变化，则控制模块20调节流经开关模组10的电流的电流值，以将该电压值发生变化的电芯与其他电芯之间的电流值调节至新获取的均衡电流。如此，调节电路100能够根据电芯的不同电压值确定对应的均衡电流值对电芯与电芯之间的电流进行调节，以减小电芯与电芯之间在充放电过程中的电压值差异，还能够将电芯与电芯之间的电量转移过程产生的热损耗控制在合适的范围。如此，能够发挥电芯的最佳充放电性能。

在某些实施方式中，开关模组10可以是一个或多个晶体管组成的模组，用于限制多个电芯之间的电流，以及限制电芯与充放电电路200之间的电流。其中，晶体管包括三极管、场效应管等，在此不作限制。开关模组10可以是多个相同类型的晶体管，或者，开关模组10中的晶体管包括多种不同的类型，在此不作限制。
在某些实施方式中，控制模块20包括寄存器，寄存器内设有预设的均衡参数。在采样模块30获取每个电芯的电压值后，控制模块20根据每个电芯的电压值和均衡参数确定对应的均衡电流，并根据均衡电流控制开关模组10的导通状态，以使电芯与电芯之间的电流值达到均衡电流。
在某些实施方式中，采样模块30包括模数转换器(analog to digital converter，ADC)。模数转换器将采集的电芯的电压值转换为电压信号传输至控制模块20，以使控制模块20获取电芯的电压值。
采样模块30的采样频率越高，则更新电芯的电压值的频率越高，使电芯与电芯之间的电流值越能够及时地根据电芯电压的变化进行相应的变化。
在某些实施方式中，采样模块30还可用于采样电芯的充放电电流值。请参阅图1，例如，采样模块30可用于采样第一电芯B1与充放电电路200之间的电流值，设第一电芯B1充电的情况下对应的电流方向为正，采样模块30可根据采样的为正数的电流值确定第一电芯B1的充电电流值；及根据采样的为负数的电流值确定第一电芯B1的放电电流值。
在某些实施方式中，采样模块30还可用于采样电芯与电芯之间的电流值，以确定电芯与电芯之间的电流值是否到达均衡电流。采样模块30可将采样的电芯与电芯之间的电流值传输至控制模块20，使控制模块20能够根据该电流值判断电芯与电芯之间的电流值是否到达均衡电流，以对应调节流经开关模组10的电流的电流值。例如，在开关模组10包括多个NMOS管的情况下，根据采样模块30采集的电芯与电芯之间的电流值调节施加在NMOS管的栅极电压。
在某些实施方式中，采样模块30和控制模块20可以是一体结构。例如，采样模块30和控制模块20集成于微处理器，微处理器与多个开关模组10连接，能够分别实现采样模块30和控制模块20的功能。
请参阅图1，在某些实施方式中，调节电路100与并联的第一电芯和第二电芯连接，开关模组10包括第一模组和第二模组，第一模组连接第一电芯及充放电电路200，第二模组连接第二电芯及充放电电路200，采样模块30用于获取第一电芯的第一电压值和第二电芯的第二电压值，控制模块20根据第一电压值、第二电压值及均衡参数调节流经第 一模组和第二模组的电流的电流值，以使第一电芯与第二电芯之间的电流值达到均衡电流。
例如，开关模组10包括第一模组N1和第二模组N2，第一模组N1和第二模组N2均与控制模块20连接。第一模组N1与第一电芯B1连接，第二模组N2与第二电芯B2连接。采样模块30能够分别获取第一电芯B1的第一电压值V1，及第二电芯B2的第二电压值V2。控制模块20根据第一电压值V1、第二电压值V2及均衡参数确定对应的均衡电流Ib，及根据均衡电流Ib调节流经第一模组N1和第二模组N2之间的电流的电流值，使第一电芯B1与第二电芯B2之间的电流值I0达到均衡电流Ib。
在一个实施例中，第一模组N1包括第一开关N1j和第二开关N1k，第二模组N2包括第一开关N2j和第二开关N2k，第一开关N1j、第二开关N1k、第一开关N2j和第二开关N2k均为NMOS管。控制模块20通过分别调节施加在第一开关N1j、第二开关N1k、第一开关N2j和第二开关N2k的栅极的电压，实现分别控制第一开关N1j、第二开关N1k、第一开关N2j和第二开关N2k的导通，从而通过控制这些开关的导通实现对流经第一模组N1和第二模组N2的电流的电流值的精准控制，以使第一电芯B1和第二电芯B2之间的电流值I0达到均衡电流Ib。
调节电路100不局限于调节并联的两个电芯之间的电流值。在某些实施方式中，调节电路100可用于调节2个、3个、4个、5个或更多个电芯之间的电流值。例如，开关模组10包括第一模组N1、第二模组N2和第三模组N3，第一模组N1、第二模组N2和第三模组N3均与控制模块20连接。第一模组N1与第一电芯B1连接，第二模组N2与第二电芯B2连接，第三模组N2与第三电芯B3连接。采样模块30能够分别获取第一电芯B1的第一电压值V1、第二电芯B2的第二电压值V2、及第三电芯B3的第三电压值V3。控制模块20根据第一电压值V1、第二电压值V2及均衡参数确定第一电芯B1和第二电芯B2对应的均衡电流Ib12、第一电芯B1和第三电芯B3对应的均衡电流Ib13、及第二电芯B2和第三电芯B3对应的均衡电流Ib23。假设V1＞V2＞V3，在一个实施例中，控制模块20通过第一模组N1和第二模组N2将第一电芯B1向第二电芯B2充电的电流值调整值Ib12；通过第一模组N1和第三模组N3将第一电芯B1向第三电芯B3充电的电流值调整值Ib13；及通过第二模组N2和第三模组N3将第二电芯B2向第三电芯B3充电的电流值调整值Ib23。
请参阅图1，下文以调节电路100调节并联的第一电芯B1和第二电芯B2之间的电流值为例进行说明。
请参阅图1，在某些实施方式中，均衡参数包括预设的第一阈值。在一个实施例中，第一阈值是满足控制模块20和采样模块30工作需求的最小电压值。请结合图2，图2是一种调节装置1000，在又一个实施例中，调节电路100可设置于调节装置1000。第一阈 值是满足调节装置1000的电系统工作的最小电压值，调节装置1000的电系统包括控制模块20和采样模块30。
在充放电电路200向调节电路100提供电流的情况下，充放电电路200能够提供控制模块20和采样模块30的工作电压，或提供满足调节装置1000的电系统工作的工作电压，以确保调节电路100或调整装置的正常工作。
在充放电电路200未向调节电路100提供电流的情况下，第一电芯B1和第二电芯B2中任意一个的电压值大于第一阈值，则可通过电压值大于第一阈值的电芯为控制模块20和采样模块30提供电能，或者为调节装置1000的电系统提供电能，以使调节电路100能够实现对第一电芯B1和第二电芯B2之间的电流值的调节功能。
请参阅图1，在某些实施方式中，设预设的第一阈值为Vy1。若第一电压值V1小于预设的第一阈值Vy1，第二电压值V2大于或等于第一阈值Vy1，则控制模块20控制第一模组N1和第二模组N2导通第二电芯B2向第一电芯B1充电的通路，使第二电芯B2以均衡电流Ib向第一电芯B1充电。若第二电压值V2小于预设的第一阈值Vy1，第一电压值V1大于或等于第一阈值Vy1，则控制模块20控制第一模组N1和第二模组N2导通第一电芯B1向第二电芯B2充电的通路，使第一电芯B1以均衡电流Ib向第二电芯B2充电。其中，均衡电流Ib是根据第一电压值V1、第二电压值V2及均衡参数确定的电流值，下同。
请参阅图1及图4，在某些实施方式中，均衡参数包括预设的过放阈值。过放阈值是电芯过放状态对应的电压值，即电芯的电压值低于过放阈值的情况下电芯处于过放状态，称为电芯“饿死”。在一些应用场景中，第一电芯B1和第二电芯B2可分别用于为不同的装置或设备供电，例如第一电芯B1用于为第一显示屏2001供电，第二电芯B2用于为第二显示屏2002供电。若第一电芯B1过放，则第一电芯B1无法为第一显示屏2001供电，可能出现第二显示屏2002能够正常进行显示，但第一显示屏2001黑屏的情况。
在充放电电路200向调节电路100提供电流的情况下，充放电电路200能够向电芯充电，使过放的电芯重新激活，恢复至能够储能和放电的状态。
在充放电电路200未向调节电路100提供电流的情况下，若第一电芯B1和第二电芯B2中任意一个的电压值小于过放阈值，另一个的电压值大于过放阈值，且大于或等于第一阈值Vy1，则调节电路100能够通过该电芯向过放的电芯充电，以激活过放的电芯。
例如，第一电压值V1小于过放阈值，第二电压值V2大于过放阈值，且第二电压值V2大于第一阈值Vy1，则控制模块20控制第一模组N1和第二模组N2导通第二电芯B2向第一电芯B1充电的通路，使第二电芯B2以均衡电流Ib向第一电芯B1充电，以激活第一电芯B1。
请参阅图1，在某些实施方式中，均衡参数包括预设的第二阈值，第二阈值是第一电芯B1和第二电芯B2在快充模式对应的电压值。在第一电压值V1和第二电压值V2均大于第二阈值的情况下，充放电电路200根据快速充电的协议对应的参数对第一电芯B1和第二电芯B2充电，或者，第一电芯B1和第二电芯B2根据快速充电的协议对应的参数向充放电电路200传输电流。
请参阅图1，在某些实施方式中，设第二阈值为Vy2，在第一电压值V1和第二电压值V2均大于第一阈值Vy1，且第一电压值V1和第二电压值V2中的任意一个小于或等于第二阈值Vy2的情况下：若第一电压值V1小于第二电压值V2(V1＜V2)的情况下，控制模块20控制第一模组N1和第二模组N2导通第二电芯B2向第一电芯B1充电的通路，使第二电芯B2以均衡电流Ib向第一电芯B1充电；若第二电压值V2小于第一电压值V1(V1＞V2)的情况下，则控制模块20控制第一模组N1和第二模组N2导通第一电芯B1向第二电芯B2充电的通路，使第一电芯B1以均衡电流Ib向第二电芯B2充电。
请参阅图1，在某些实施方式中，均衡参数包括预设的第三阈值，第三阈值是第一电芯B1和第二电芯B2对应的涓流充电电压。均衡电流包括第一均衡值及第二均衡值，设第三阈值为Vy3，第一均衡值为Ib1，第二均衡值为Ib2，Ib1＜Ib2。在第一电压值V1和第二电压值V2均大于第一阈值Vy1且均小于预设的第三阈值Vy3的情况下，控制模块20采用第一均衡值Ib1作为均衡电流Ib，在第一电压值V1和第二电压值V2中的任意一个大于第三阈值Vy3，且第一电压值V1和第二电压值V2中的任意一个小于或等于第二阈值Vy2的情况下，控制模块20采用第二均衡值Ib2作为均衡电流Ib。即，在第一电压值V1和第二电压值V2均大于第一阈值Vy1，且第一电压值V1和第二电压值V2中的任意一个小于或等于第二阈值Vy2的情况下，若第一电压值V1和第二电压值V2均小于涓流充电电压，则采用较小的第一均衡值Ib1作为均衡电流Ib，以避免过充或过放，否则，采用较大的第二均衡值Ib2作为均衡电流Ib，以提高第一电芯B1和第二电芯B2之间的电量转移效率。
请结合表1，在一个实施例中，第一阈值Vy1＝2.2V，第二阈值Vy2＝3.4V，第三阈值Vy3＝2.5V，第一均衡值Ib1＝100mA，第二均衡值Ib2＝300mA。表1是第一电压值V1和第二电压值V2与均衡电流Ib的对应关系。在2.5V＞V1＞2.2V，且2.5V＞V2＞2.2V的情况下Ib＝100mA。在V1≥2.5V，V2≥2.5V，且V1和V2中的任意一个小于或等于3.4V的情况下Ib＝300mA。在V1＞3.4V，且V2＞3.4V的情况下，均衡电流Ib根据V1和V2之间的压差△V确定。

请参阅图1，在某些实施方式中，均衡参数还包括压差值与均衡电流之间的映射关系，在第一电压值V1和第二电压值V2均大于预设的第二阈值Vy2的情况下，控制模块20根据第一电压值V1与第二电压值V2之间的压差值及映射关系获取均衡电流。
其中，映射关系可包括映射关系表、映射关系曲线、映射关系式等，在此不作限制。
请结合表2，表2是第一电压值V1与第二电压值V2之间的压差值△与均衡电流Ib之间的映射关系表的示例。根据表2的映射关系，压差值△的绝对值越小，则对应的均衡电流Ib越大，以提高电芯B1和电芯B2之间的电量转移效率；压差值△的绝对值越大，则对应的均衡电流Ib越小，以避免产生过高的热功率损耗，以防止产生较高的热量导致调节电路100周边的线路或元器件被烧坏。

请参阅图1，并结合表2，在某些实施方式中，均衡电流与对应的压差值的乘积小于预设的功率阈值。如此，可以防止电芯与电芯之间的电量转移过程中产生过高的热功率损耗，避免调节电路100周边的线路或元器件被烧坏。
在某些实施方式中，可以根据电芯过流状态对应的电流值设置均衡电流的最大值，即根据均衡参数确定的均衡电流的最大值小于电芯的过流电流值，以确保电芯与电芯之间的电量转换过程中不发生过流。
请参阅图1及图2，本申请的实施方式还提供一种调节装置1000。调节装置1000包括上述实施方式中的调节电路100。在一个实施例中，调节装置1000为芯片，调节电路100集成在芯片上。

请参阅图4，在某些实施方式中，电子设备2000还可包括第一显示屏2001和第二显示屏2002，电芯包括第一电芯B1和第二电芯B2，第一电芯B1用于为第一显示屏2001供电，第二电芯B2用于为第二显示屏2002供电。在某些实施方式中，第一显示屏2001能相对第二显示屏2002折叠，即，第一显示屏2001和第二显示屏2002分别位于电子设备2000的同一侧，此时电子设备2000为具有折叠屏的设备。在另一些实施方式中，第一显示屏2001和第二显示屏2002分别位于电子设备2000的前后侧。
在某些实施方式中，在第一电芯B1和第二电芯B2分别为第一显示屏2001和第二显示屏2002供电的情况下，调节装置1000能够调节第一电芯B1和第二电芯B2之间的电流I0，使电流I0达到均衡电流，均衡电流的取值随第一电芯B1的第一电压值V1和第二电芯B2的第二电压值V2更新。如此，能够减小第一电芯B1和第二电芯B2之间的电压差异和电量差异，避免第一电芯B1和第二电芯B2中的一个电量耗尽，而另一个还剩余较多电量的情况发生而导致第一显示屏2001和第二显示屏2002中的一个亮屏另一个熄灭。
