具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。应理解，本说明书中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
为了更加清楚地理解本申请，以下将介绍电容及其充放电过程，便于后续理解本申请的方案。但应理解，以下介绍的内容仅仅是为了更好的理解本申请，不应对本申请造成特别限定。
电容是是一种以电场形式储存能量的无源器件，在有需要的时候，电容能够把储存的能量释出至电路。电容可以由两块导电的平行板构成，在板之间可以填充有绝缘物质或介电物质，当然，电容也可以具有其他的结构，例如，电容可以由多于两块的平行板组成，或者组成电容的板之间也可以是不平行。
图1和图2分别示出了电容在充电过程中和放电过程中的示意性图。
如图1所示为电容在充电过程中的示意性图，若电容C与直流电源相接，电路中有电流流通，电容的两块板会分别获得数量相等的相反电荷，并且随着充电过程的进行，其两端的电位差V C逐渐增大。一旦电容两端电压V C增大至与电源电压V相等时，即V C＝V，电容充电过程结束，电路中没有电流流动，此时电容的充电过程完成。
如图2所述为电容在放电过程中的示意性图，由于电容充电过程完成后，没有电流流过电容器，所以在直流电路中，电容可等效为开路，电容上的电压V C不能突变。当切断电容与电源的连接后，将电容与电阻R 2连接，此时，电容通过电阻R 2进行放电，电容储存的能量会逐渐减少，电容的两块板之间的电压V C会逐渐下降直到电压V C为0为止。
在电源对电池进行充电的过程中，由于电池的储存能量和充电速度难以满足人们越来越高的需求，因此，考虑到电容的充放电性能，本申请实施例提供了以下的充放电装置和供电方法，可以提高电池的储存能力以及充电速度。
下面结合图3，对本申请实施例提供的充放电装置300进行详细说明。
如图3所示，本申请实施例提供的充放电装置300可以包括第一支路320，第一支路包括电池321；第二支路330，第二支路330与第一支路320并联，包括电容组331所述电容组331用于存储电能，以及用于为所述电池321充电和/或为与所述充放电装置连接的待供电的器件340供电。
可选地，本申请实施例中的电池可以为硅基负极锂离子电池，或者为其它电池，如，蓄电池等。
在本申请实施例中，可以存在多个第一支路，该多个第一支路是相互并联的。以及也可以存在多个第二支路，该多个第二支路是相互并联的。
本申请实施例中的电容可以为法拉电容，法拉电容又称超级电容，法拉电容具有充电速度快且存储电量大的特性。
本申请实施例中的电池与电容组可以分别设置在不同的保护板上，保护板之间进行并联；也可以设置在同一保护板上，此时电容组设置于电池壳体 的内部，或者电容组与电池分离设置在该保护板上。
本申请实施例中的电容组331可以为单个电容，也可以为多个电容串联，电容串联的个数可以为两个或者更多。
在本申请实施例中，串联电容的个数可以根据电池321的最大电压确定，串联之后的电容组331的击穿电压可以大于电池321的最大电压，避免由于电池321的最大电压大于串联之后的电容组331的击穿电压所带来的电容被击穿的情况发生。
例如，若电池321的最大电压为4.5V，一个电容的击穿电压为5V，可以将一个电容331(本申请实施中的电容组)与电池321进行并联。在供电电源对电池321和电容组331进行充电的时候，由于电容具有快速充电的特性，与电池321相比可能会在非常短的时间内充满，若继续充电，此时供电电源继续对电池321进行充电，由于电池321的最大电压为4.5V，而电容组331的击穿电压为5V，即使电池321两端的电压达到电池321的最大电压，电池321两端的电压仍然小于电容组331的击穿电压，因此可以避免电容组331两端电压过大而导致电容组331击穿，起到保护电容组的作用。
例如，若电池321的最大电压为4.5V，一个电容的击穿电压为3V，可以将两个击穿电压为3V的电容串联起来再与电池进行并联，这种情况下，电容组331的击穿电压相当于为6V。在充电通路310与供电电源350连接时，即供电电源350对电池321和电容331进行充电的时候，即使电池321两端的电压达到电池321的最大电压，电池321两端的电压仍然小于电容组331的击穿电压，仍然可以避免电容组331两端电压过大而导致电容击穿。若没有将两个击穿电压为3V的电容串联，直接将电池321与击穿电压为3V的电容并联，在供电电源350对电池321和电容组331进行充电的时候，若电池321两端的电压大于电容组331的击穿电压，会将电容组331中的电容击穿，导致电容失效。
在上述情况下，可以将两个击穿电压为3V的电容串联，也可以将击穿电压为3V的三个或者更多的电容串联，具体可以根据对充放电装置的电量存储需求而定。
本申请实施例中多个电容的型号可以相同，也可以不同。本申请实施例中多个电容的击穿电压可以相同，也可以不相同，本申请对此不作具体限定，只要能够满足串联之后的击穿电压大于电池的最大电压均可应用本申请实施例。
在本申请实施例中，第一支路320与第二支路330并联，第一支路320包括电池321，第二支路330包括电容组331，在这种情况下，相当于电池321与电容组331并联。
为了便于理解，以下以电容组为单个电容为例进行说明，在供电电源对充放电装置300进行充电时，由于电容的充电速度快，因此在相同的时间内电容所储存的电量远远大于电池电量。
例如，供电电源该充放电装置300进行充电，假设初始条件下电容和电 池的电量均为零，在对充放电装置充电一段时间后，电池的电量增长量可能为100mAh，而电容的电量增长量可能能够达到1000mAh，与电池相比，电容在相同的充电时间内能够存储更多的电量。
在本申请提供的充放电装置300中，在电池两端并联一电容组，由于电容组具有存储电量大且快速充电的特性，因此，在供电电源对该充放电装置进行充电时，能够保证充放电装置的存储的电量，同时也能够提升充放电装置的充电速度。
此外，由于电容对温度的敏感程度较低，供电电源对电池和电容充电的过程中，当环境温度较低时，有可能电池无法存储电量，但此时电容仍然可以存储电量，能够提高充放电装置在低温环境下的存储电量的能力。
本申请实施例中的电容组331可以为电池321充电，也可以为与充放电装置300连接的待供电的器件进行供电。
本申请实施例中的待供电的器件可以为一个或多个；多种待供电的器件的种类可以相同，也可以不同；在该充放电装置对多种待供电的器件进行供电的时候，可以同时进行供电，也可以不同时进行供电。
可选地，在一些实施例中，如图4所示，充放电装置300还可以包括充电通路310和控制单元360。
充电通路310，与供电电源350连接。
控制单元360，用于控制充电通路310与第一支路320和/或第二支路330连接，以使供电电源350为电池321和/或电容组331充电。
本申请实施例中的充电通路310可以为带有接口的导线，充电通路310通过接口可以与供电电源350连接。在充电通路310与供电电源350连接时，供电电源350可以为电池321和电容组331进行充电。
本申请实施例中，也可以有供电通路，充放电装置300通过供电通路可以为待供电器件340供电。在充电通路310与供电电源350断开连接时，可以由电池321和电容组331为待供电器件340供电；在充电通路310与供电电源350连接时，供电电源350为电池321和电容组331进行充电的同时，电池321和电容组331也可以为待供电器件340供电。
在供电电源350对该充放电装置300进行充电的过程中，供电电源350可以为充放电装置进行充电，也可以为与充放电装置连接的待供电的器件进行供电。
若待供电的器件为以手机中需要供电的器件为例，在供电电源对手机充电的过程中，一方面，供电电源对手机中的电池和电容组进行充电，另一方面，若手机应用程序打开或者手机处于非关机状态下，供电电源同时可以为手机中需要消耗电量的器件进行供电，例如，手机屏幕的亮度，微信应用程序等。
在断开供电电源与手机的连接的情况下，若手机应用程序打开或者手机处于非关机状态下，则由手机中的电池或电容组为手机需要消耗电量的器件进行供电。
可选地，在一些实施例中，在所述充电通路310未与供电电源350连接的情况下，所述电容组331用于为所述电池321充电和/或为与所述充放电装置连接的待供电的器件340供电。
具体地，在充电通路310与供电电源350断开的情况下，电容组331为电池321充电和待供电的器件340供电。当然，本申请实施例中，也可以在充电通路310与供电电源350连接的情况下，电容组331为电池321充电和待供电的器件340进行供电。
本申请实施例中，在充电通路310与供电电源350连接时，供电电源350为电容组331与电池321进行充电，由于电容组331在充电时可以存储电量且充电速度更快，相比于仅有电池的充放电装置，在与供电电源连接时，充放电装置300可以存储更多的电量同时充电速度更快，在充电通路310与供电电源350断开连接时，电容组331可以为待供电器件340供电也可以为电池321充电，相比于只有电池321没有并联电容组331的情况下，由于有了能够存储电量的电容组的存在，充放电装置300可以提供更多的电量。
可选地，在一些实施例中，所述控制单元360具体用于：控制充电通路310先与第二支路330连接，再与第一支路320连接，以使供电电源350先为电容组331充电，再为电池321充电；或控制单元360用于控制充电通路310与第一支路320和第二支路330连接，以使供电电源350同时为电池321和电容组331充电。
在供电电源350对充放电装置300进行充电的情况下，若供电电源350同时对电池321和电容组331进行充电，在相同时间内可以增加充电电量；然而由于电容组的充电速度远大于电池，在供电电源350同时对电池和电容组进行充电的过程中，电池321可能也会影响供电电源350对电容组331进行充电的速度。因此，为了避免这一情况，控制单元360可以先控制充电通路310与电池组331连接，再控制充电通路310与电池321连接。
本申请实施例中的控制单元360可以为具体的硬件型控制单元，也可以为程序式的控制单元，本申请对此不作具体限定，只要能够控制电池与供电电源的连通或断开均可应用于本申请实施例。
本申请实施例中的控制单元360可以串联于与第一支路320相连的主路，例如如图4中所示，也可以串联于第一支路320，本申请对此不作具体限定。应理解，本申请实施例中，在控制单元360控制充电通路310与电池321连接时，可以控制充电通路310与电池组331断开，也可以控制充电通路310与电池组331保持连接，本申请对此不作具体限定。
在控制单元360先控制充电通路310与电容组331连接时，即充电通路310与电容组331连接，且与电池321断开，这种情况下，相当于供电电源350仅对电容组331进行充电，可以快速充到电容组331的最大电压，能够减少在供电电源350同时对电池321和电容组331进行充电时，由于电池321的存在，影响供电电源350对电容组331的充电速度。
在本申请提供的充放电装置300中，在供电电源350对充放电装置300 进行充电的情况下，通过控制单元360控制充电通路310与电容组331连接从而控制供电电源350仅对电容组331进行充电，能够减少电池321对电容组331的充电速度影响。
上文中提到控制单元360可以控制充电通路310先与所述第二支路330连接，再与所述第一支路320连接，那么什么时候控制单元360可以控制充电通路310与第二支路330连接，什么时候控制单元360可以控制充电通路310与第一支路320连接？以下将具体介绍。
在检测到充电通路310与供电电源350连接的情况下，控制单元360可以控制充电通路310与第二支路330连接，以用于供电电源350通过充电通路310为电容组331充电；在电容组331的电压达到第一阈值时，控制单元360可以控制充电通路310与第一支路320连接，以用于供电电源350通过充电通路310为电池321充电。
可选地，在一些实施例中，在供电电源350对充放电装置300进行充电前以及电容组331与供电电源350连通的情况下，控制单元360可以控制电池321与供电电源350断开。
本申请实施例中，供电电源350在对充放电装置300进行充电前，可以先控制充电通路310与第一支路320断开以及控制充电通路310与第二支路330连接，即控制电池321与供电电源350断开，电容组331与供电电源350连通，在这种情况下，供电电源350仅对电容组331进行充电，电容组331可以快速达到充电电压。在供电电源350对电容组331充电至电容组的电压达到第一阈值时，控制接通电池321与供电电源350，使得供电电源350对电池321进行充电。
本申请实施例中的第一阈值可以是电容组的最大电压，也可以小于电容组的最大电压，本申请对此不作具体限定。
可以理解的是，在供电电源350对电容组331充电至电容组的最大电压时，控制接通充电通路310与第二支路330，即控制接通电池321与供电电源350后，供电电源350对电池321进行充电，在这种情况下，电容组331与供电电源350可以接通，也可以断开，本申请对此不作限定。
本申请实施例中，在充电通路310与供电电源350断开连接的情况下，可以先由电容组331为待供电的器件340进行供电，再由电池321为待供电的器件340进行供电。
可选地，在一些实施例中，第一支路320可以包括与所述电池321串联的第一开关322，第二支路330可以包括与所述电容组331串联的第二开关332，如图5所示，控制单元360可以通过控制第一开关322的闭合来控制充电通路310与第一支路320连接，通过控制第二开关332的闭合来控制充电通路310与第二支路330连接。
本申请实施例中的第一开关322可以串联于第一支路320，也可以串联于其他支路或主路，本申请对此不作限定，只要控制单元360能够控制第一开关322的接通均可应用本申请实施例。
类似地，本申请实施例中的第二开关332可以串联于第二支路330，也可以串联于其他支路或主路，本申请对此不作限定，只要控制单元360能够控制第二开关332的接通均可应用本申请实施例。
在充放电装置300向与充放电装置连接的待供电的器件340进行供电的时候，电池321可以向待供电的器件340进行供电，电容331也可以向待供电的器件340进行供电，或者电容331向电池321充电再由电池321向待供电的器件340进行供电，本申请对此不作限定。
考虑到在电容331向电池321充电再由电池321向待供电的器件340进行供电的过程中，可能会有电量的损耗，因此，控制单元360能够控制电池321或电容组331与待供电的器件340的连通或断开。
可选地，在一些实施例中，在充电通路310未与供电电源350连接的情况下，控制单元360控制待供电的器件340先与第二支路330连接，再与第一支路320连接，以便于先由电容组331为待供电的器件340供电，再由电池321为待供电的器件340供电。
具体地，在检测到充电通路310与供电电源350断开的情况下，控制单元360控制待供电的器件340先与第二支路320连接，这种情况下，第二支路320上的电容组331为待供电的器件340供电，再控制待供电的器件340与第一支路330连接，以便于由第一支路330上的电池为待供电的器件340供电。
可选地，在一些实施例中，在检测到充电通路310未与供电电源350连接的情况下，当电容组331的电压大于或等于第二阈值时，控制单元360控制待供电器件340与第二支路330连接，以便于电容组331向待供电器件340进行供电；当电容组331的电量低于第二阈值时，控制单元360控制控制待供电器件340与第一支路320连接，以便于电池321为待供电的器件340进行供电。
可以理解的是，在控制单元360控制待供电器件340与第二支路330连接时，即控制电容组331与待供电的器件340连接，电池321和待供电的器件340断开，这种情况下，相当于电容组331直接对待供电的器件340进行供电，避免电容组331对电池321充电再由电池321对待供电的器件340进行供电，能够减少在供电过程中的电量损耗。
在本申请提供的充放电装置300中，在充放电装置向待供电的器件进行供电的情况下，通过控制单元360控制待供电器件340与第二支路330的连接，也就是控制电容组与待供电的器件连接以及电池与待供电的器件断开，能够避免电容组向电池充电再由电池向待供电器件进行供电，能够有效减少电量的损耗。
在充放电装置300向待供电的器件340进行供电的情况下，为了减少电量的损耗，控制单元360控制电池321与待供电的器件340断开，若电容组331的电压比较小的时候，此时由于电容组331的电压较小，可能无法向待供电的器件340进行供电。因此，应该考虑到电容组331是否能够正常向待 供电的器件340进行供电。
可选地，在一些实施例中，在充放电装置300向待供电的器件340进行供电的情况下，控制单元360可以在电容组331的电压大于或等于第二阈值时，控制待供电器件340先与第二支路330连接，以便于电容组331向待供电的器件340进行供电；在电容组331的电压低于第二阈值时，控制单元360控制待供电的器件340再与第一支路320接通，以便于电池321为待供电的器件340进行供电。
本申请实施例中，电容组331的电压可以通过监测单元进行实时监测，当电容组331的电压大于或等于第二阈值时，控制单360元控制电容组330与待供电的器件340连接，电池321与待供电的器件340断开，这种情况下，相当于电容组331向待供电的器件340进行供电；当电容组331的电压低于第二阈值时，控制单元360控制电池321与待供电器件340接通，此时，由电池321向待供电的器件340进行供电。
应理解，本申请实施例中，控制单元360控制供电器件340再与第一支路320连接时，待供电器件340与第二支路330可以连接，也可以断开，本申请对此不作具体限定。在待供电器件340与第二支路330连接时，电池321可以为待供电器件340供电，也可以为电容组331充电；在待供电器件340与第二支路330断开时，电池321仅为待供电器件340供电。
本申请实施例中的第二阈值可以根据待供电器件340进行设定，也可以根据经验进行设定。
在极限情况下，第二阈值可以设定为0，即只有保证电容组331有电压的情况下才能向待供电的器件340进行供电；第二阈值的设定也可以根据经验进行设定，例如，由经验可得，在充放电装置向待供电的器件进行供电的情况下，当电容组331的电压大于3V时，充放电装置才能向待供电的器件340进行供电，则第一阈值可以设定为3。
在本申请提供的充放电装置300中，控制单元在充放电装置进行供电的情况下且电容组的电压大于或等于第二阈值时，控制待供电器件与电容组连接，待供电的器件与电池断开，能够减少电量的损耗同时能够保证电容组对待供电器件的供电。
可选地，在一些实施例中，第一支路320包括与所述电池321串联的第一开关322，第二支路330包括与所述电容组331串联的第二开关332，如图5所示，控制单元360可以通过控制第一开关322的闭合来控制待供电器件340与第一支路320连接，通过控制第二开关332的闭合来控制待供电器件340与第二支路330连接。
本申请实施例中的第一开关323可以串联于第一支路320，也可以串联于其他支路或主路，本申请对此不作限定，只要控制单元360能够控制第一开关322的接通以控制待供电器件340与第一支路320的接通均可应用本申请实施例。
类似地，本申请实施例中的第二开关332可以串联于第一支路，也可以 串联于其他支路或主路，本申请对此不作限定，只要控制单元360能够控制第二开关332的接通以控制待供电器件340与第二支路330的接通均可应用本申请实施例。
上文阐述了在供电电源对充放电装置300进行充电的过程和充放电装置300对待供电的器件进行供电的过程，在这两个过程中，可以实现供电电源和电容同时处于工作状态中(供电电源对充放电装置进行充电的过程中，同时对供电电源和电容充电；充放电装置对待供电的器件进行供电的过程中，电池和电容组同时对待供电的器件进行供电)，若电池电压高于电容组的电压时，有可能电池会向电容组反向充电，造成回路中的电量损失。因此，应该避免电池向电容组反向充电。
可选地，在一些实施例中，控制单元360在电池电压大于电容组的电压时，阻止电池321向电容组331充电。
在本申请提供的充放电装置300中，在电池电压大于电容组电压时，控制单元360阻止电池321向电容组331充电，能够避免电池321向电容组331反向充电，避免回路中的电量损失。
可选地，在一些实施例中，第一支路320可以包括与所述电池321串联的第一开关322，控制单元360可以通过控制第一开关322的断开来实现阻止电池321向电容组331充电；第二支路可以包括与所述电容组331串联的第二开关332，控制单元360可以通过控制第二开关332的断开，来阻止电池321向电容组331充电。
本申请实施例中，在供电电源350对电池321和电容组331进行充电时，当电池电压大于电容组电压时，可以通过控制单元360控制第一开关322断开，此时，供电电源350对电容组331进行充电；或者控制单元360控制第二开关332断开，此时，供电电源350只对电池321进行充电，不会造成电池321向电容组331反向充电。
在充放电装置300向待供电的器件340进行供电时(第一开关323和第二开关325均处于闭合状态)，当电池电压大于电容组电压时，可以通过控制单元360控制第一开关322断开，由于第一开关322的断开使得电池321和电容组331之间的回路断开，电池321不会向电容组331进行反向充电，此时，由电容组331向待供电的器件340进行供电；或者控制单元360控制第二开关332断开，由于第二开关332的断开使得电池321和电容组331之间的回路断开，电池321不会向电容组331进行反向充电，此时，由电池321向待供电的器件340进行供电。
在电池电压大于电容组电压时，上述实施例中是通过控制单元阻止电池向电容组充电来实现电池向电容组反向进行充电的，在一些情况下，电容组也可以向电池进行充电。
可选地，在一些实施例中，控制单元360在电池电压大于电容组电压时，也可以控制电容组331向电池321进行充电。
在本申请提供的充放电装置300中，当电池电压大于电容组电压时，通 过第三控制单元控制电容组向电池进行充电，能够避免电池向电容组反向充电，同时由于电容组的电量存储的时间较短，将电容组的电量存储到电池中，从而可以实现随时为待供电器件进行供电。
本申请实施例中的电池的电压和电容的电压可以通过电压监测单元来实现，电压监测单元可以实时监测电池的电压和电容的电压，并且可以将监测到的电压发送至以上提到的各个控制单元。
本申请实施例中的用于监测电池的电压的监测单元和用于监测电容的电压的监测单元可以为同一个监测单元，也可以为不同的监测单元，本申请对此不作限定，只要能够监测到电池电压和电容组电压均可应用本申请实施例。
以上介绍的控制单元可以为同一个控制单元，也可以为不同的控制单元，例如，可以分别由第一控制单元、第二控制单元、第三控制单元来实现相应的功能，本申请对此不作具体限定。
可选地，在本申请实施例中，若控制单元为不同的控制单元，第一控制单元、第二控制单元和第三控制单元可以集成在一个控制器件中，也即可以由一个控制器件实现第一控制单元、第二控制单元和第三控制单元的功能，或者，第一控制单元、第二控制单元和第三控制单元可以分别由不同的控制器件实现。
