在实际应用中，汽车电瓶容易因为老化、破损等原因导致功率不足而无法进行打火(在打火后可以正常使用，但是无法满足打火时所需的较高功率)，因此，在汽车电瓶的电压不足时，相关技术采用启动电源等电源设备辅助进行打火。其中，若在汽车不启动时，电源设备给汽车电瓶或发动机供电，则会导致电源设备的电量损耗。为了使得电源设备有效地输出能量，需要对电源设备进行放电控制。因此，如何准确地控制电源设备为发动机供电是本领域亟需解决的技术问题。
请参阅图1和图2，本申请实施方式的电路结构10能够实现电源设备400与汽车电瓶600的连接，电源设备400包括电源组件410。电路结构10包括第一电源端口11、第二电源端口12、采样模块13、第一开关14和控制器15。第一电源端口11能够分别通过采样模块13和第一开关14连接汽车电瓶600的第一极。第二电源端口12能够与汽车电瓶600的第二极连接。控制器15用于根据采样模块13上的采样电信号控制第一开关14的状态，其中，第一开关14的状态包括导通、断开等。
本申请实施方式的电路结构10中，电源端口(第一电源端口11和第二电源端口12)通过采样模块13与汽车电瓶600形成回路，电源端口可以通过采样模块13向汽车电瓶600放电，由于汽车进行打火时，汽车电瓶600的电压会发生变化，因此，回路上的电信号也会发生变化，此时采样模块13上的采样电信号可以反映是否存在该变化，通过获取 采样模块13上的采样电信号，即可根据采样电信号快速、准确地控制第一开关14的状态，从而可以准确地控制电源端口为汽车发动机供电。
电源设备400可以是启动电源、应急电源等设备，电源设备400能够通过电路结构10与汽车电瓶600连接，电源设备400用于辅助汽车进行打火。电源设备400包括电源组件410，电源组件410存储的电能能够用于辅助汽车进行打火。
第一电源端口11可以用于连接电源组件410的第一极和汽车电瓶600的第一极，第二电源端口12可以用于连接电源组件410的第二极和汽车电瓶600的第二极。电源组件410的第一极可以是电源组件410的正极和负极中的一个，电源组件410的第二极可以是电源组件410的正极和负极中的另一个。在一个实施例中，第一电源端口11可以用于连接电源组件410的正极，第二电源端口12可以用于连接电源组件410的负极。
第一电源端口11能够分别通过采样模块13和第一开关14连接汽车电瓶600的第一极，从而形成两条支路。第一条支路是第一电源端口11通过采样模块13连接汽车电瓶600的第一极，通过第一条支路可以检测汽车电瓶600的状态(例如是否放电)。第二条支路是第一电源端口11通过第一开关14连接汽车电瓶600的第一极，通过第二条支路可以使得第一电源端口11能够向汽车放电。

利用控制器15可以实现对电路结构10的控制。控制器15可以包括驱动板、其他通用处理器、数字信号处理器(Digital Signal Processor，DSP)、专用集成电路(Application Specific Integrated Circuit，ASIC)、现成可编程门阵列(Field-Programmable Gate Array，FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件中的一种或多种组件。其中，驱动板可以包括中央处理单元(Central Processing Unit，CPU)。
请继续参阅图2，在某些实施方式中，采样模块13包括采样电阻132和第二开关134，在第二开关134导通时，控制器15用于根据采样电阻132上的采样电信号控制第一开关14的状态。
如此，能够通过第二开关134实现对采样电阻132的控制，从而使得采样电阻132能 够接入电路或断开。在第二开关134导通时，采样电阻132接入电路中，第一电源端口11能够通过采样电阻132和第二开关134连接汽车电瓶600的第一极，因此，在汽车电瓶600的电压发生变化时，采样电阻132上的采样电信号可以反映是否存在该变化，因此，通过获取采样电阻132上的采样电信号，即可根据采样电信号快速、准确地控制第一开关14的状态，从而可以准确地控制电源端口为汽车发动机供电。
采样电阻132的具体电阻值可以根据电路需求进行设计，在此不做具体限定。在一个实施例中，采样电阻132的电阻值可以是10毫欧、20毫欧(mΩ)。
在某些实施方式中，第一开关14的承受功率大于第二开关134的承受功率，第二开关134的承受功率较小可以便于减小采样模块13对应的支路的回路电流、降低回路所损耗的功率，从而降低电源设备400的能量消耗。
在某些实施方式中，控制器15用于在控制第一开关14闭合时，控制第二开关134断开。
在第一开关14闭合时，电源设备400通过第一电源端口11向汽车放电，此时不需要再通过采样模块13检测汽车电瓶600的状态，因此，可以控制第二开关134断开，从而避免不必要的能量消耗。
在某些实施方式中，控制器15用于在控制第二开关134闭合时，控制第一开关14断开。
在第二开关134闭合时，电路结构10通过采样模块13检测汽车电瓶600的状态，此时电源设备400不用通过第一电源端口11向汽车放电，因此，可以控制第一开关14断开，从而避免不必要的能量消耗。
请继续参阅图2，在某些实施方式中，采样模块13还包括限流电阻136，第一电源端口11能够通过采样电阻132、限流电阻136和第二开关134连接汽车电瓶600的第一极。
如此，通过限流电阻136可以减小采样模块13对应的支路的回路电流、降低回路所损耗的功率，从而降低电源设备400的能量消耗，并且可以避免电流过大而导致第二开关134、汽车电瓶600等元件损坏。
在某些实施方式中，限流电阻136的电阻值大于采样电阻132的电阻值，如此，限流电阻136可以起到较好的限流作用。在一个实施例中，限流电阻136的电阻值为100欧(Ω)。
在某些实施方式中，控制器15用于根据采样电信号确定汽车是否进行打火。
具体地，电源端口通过采样模块13与汽车电瓶600形成回路，电源端口可以通过采样模块13向汽车电瓶600放电，由于汽车进行打火时，汽车电瓶600的电压会发生变化，因此，回路上的电信号也会发生变化，此时采样模块13上的采样电信号可以反映是否存在该变化，通过获取采样模块13上的采样电信号，即可确定汽车是否进行打火，从而能 够快速、准确地确定汽车是否打火，进而可以准确地控制电源端口为汽车发动机供电。
在某些实施方式中，采样电信号的值与采样模块13的电流相关，控制器15能够在基于采样电信号确定采样模块13的电流的变化率大于预设电流变化率的情况下，确定汽车进行打火。
如此，能够根据电流的变化率准确地判断汽车是否进行打火。具体地，由于汽车进行打火时，汽车电瓶600会向汽车发动机放电，因此，汽车电瓶600的电压会变低，在采样模块13导通时，由于电源组件410的电压大于汽车电瓶600的电压，因此，电源组件410会向汽车电瓶600放电，从而形成回路。其中，由于汽车打火时所需要的功率较高，汽车电瓶600的电压下降比较明显，因此，此时电源组件410与汽车电瓶600的压差也会比较大。可以基于采样电信号确定采样模块13的电流的变化率是否大于预设电流变化率，若是，则说明电源组件410与汽车电瓶600的压差比较大，可以确定汽车进行打火，若否，则说明电源组件410与汽车电瓶600的压差比较小，可以确定汽车没有进行打火。在一个实施例中，采样电信号为电流信号，可以直接判断采样电信号的电流变化率是否大于预设电流变化率。在另一个实施例中，采样电信号为电压信号，可以通过电压信号与采样电阻132的电阻值来判断电流变化率是否大于预设电流变化率。预设电流变化率可以根据实际电路的设计进行调整，不同的采样电阻132、限流电阻136可以对应不同的预设电流变化率。在一个实施例中，预设电流变化率例如为20mA/2ms。

在某些实施方式中，采样电信号的值与采样模块13的电压相关，控制器15能够在基于采样电信号确定采样模块13的电压的变化率大于预设电压变化率的情况下，确定汽车进行打火。
如此，能够根据电压的变化率快速、准确地判断汽车是否进行打火。具体地，由于汽车进行打火时，汽车电瓶600会向汽车发动机放电，因此，汽车电瓶600的电压会变低，在采样模块13导通时，由于电源组件410的电压大于汽车电瓶600的电压，因此，电源组件410会向汽车电瓶600放电，从而形成回路。其中，由于汽车打火时所需要的功率较高，汽车电瓶600的电压下降比较明显，因此，此时电源组件410与汽车电瓶600的压差也会比较大。可以基于采样电信号确定采样模块13的电压的变化率是否大于预设电压变化率，若是，则说明电源组件410与汽车电瓶600的压差比较大，可以确定汽车进行打火，若否，则说明电源组件410与汽车电瓶600的压差比较小，可以确定汽车没有进行打火。在一个实施例中，采样电信号为电压信号，可以直接通过判断电压变化率是否大于预设电 压变化率。预设电压变化率可以根据实际电路的设计进行调整，不同的采样电阻132、限流电阻136可以对应不同的预设电压变化率。在一个实施例中，预设电压变化率例如为1V/2ms。
在某些实施方式中，控制器15能够在基于采样电信号确定采样模块13的当前的电压大于预设电压值的情况下，确定汽车进行打火。如此，能够根据电压快速地判断汽车是否进行打火。
在某些实施方式中，控制器15用于在确定汽车进行打火的情况下，控制第一开关14导通；在确定汽车没有进行打火的情况下，控制第一开关14断开。
如此，能够在快速、准确地控制第一开关14的状态，从而可以准确地控制电源端口为汽车发动机供电。具体地，在汽车进行打火时，第一开关14导通，从而电源组件410能够通过第一开关14向汽车发动机供电以辅助打火；在汽车没有进行打火时，第一开关14断开，从而避免电源组件410向汽车电瓶600进行放电而造成不必要的能量消耗。
请继续参阅图2，在某些实施方式中，电路结构10还包括信号放大模块16，信号放大模块16用于放大采样电信号，控制器15用于根据放大后的采样电信号控制第一开关14的状态。
如此，能够根据放大后的采样电信号准确地控制第一开关14的状态。具体地，由于采样电阻132的电阻值比较小和/或限流电阻136的电阻值比较大等原因，采样模块13上的采样电信号可能比较小，因此可以采用信号放大模块16将采样电信号进行放大，从而可以根据放大后的采样电信号准确地确定汽车是否进行打火、准确地控制第一开关14的状态。信号放大模块16可以是能够放大信号的任意电子元件，在此不做具体限定。在一个实施例中，信号放大模块16可以是运算放大器。
在某些实施方式中，控制器15用于控制采样模块13以预设周期导通，以根据采样电信号控制第一开关14的状态。
如此，能够降低电源组件410的能量消耗。具体地，采样模块13以预设周期导通，具体是指采样模块13导通一段时间，然后关闭一段时间，一直循环，直到检测到汽车点火或电源设备400与汽车电瓶600的连接断开，相较于采样模块13一直导通，可以在根据采样电信号比较准确地检测汽车电瓶600的状态的同时，降低电源组件410的能量消耗。预设周期的具体取值可以根据需求进行设置，其中，导通的时间越长，检测结果越准确，导通的时间越短，能量消耗越低。
请继续参阅图2，在某些实施方式中，电路结构10包括电子开关驱动电源171和电子开关控制电路172，电子开关驱动电源171用于为第一开关14提供工作电压，电子开关控制电路172用于基于控制器15的信号控制第一开关14的状态。

在某些实施方式中，第一开关14可以包括大功率电子开关，控制器15可能无法直接控制第一开关14的状态，因此，可以控制器15可以通过电子开关控制电路172控制第一开关14的状态，其中，电子开关控制电路172例如可以是驱动电路，驱动电路能够用于基于控制器15的信号控制大功率电子开关的状态。如此，能够通过电子开关控制电路172准确地控制第一开关14的状态。
在某些实施方式中，电路结构10包括控制器电源电路173，控制器电源电路173用于为控制器15提供工作电压。
控制器电源电路173可以用于将电源组件410或汽车电瓶600的电压转换为工作电压以提供给控制器15或者其他电路元件进行工作。在一个实施例中，控制器电源电路173可以为稳压电路。如此，能够便于控制器15正常工作。
在某些实施方式中，电路结构10包括电压检测电路174，电压检测电路174用于检测汽车电瓶600的电压值，控制器15用于根据汽车电瓶600的电压值输出控制信号。
具体地，在某些实施方式中，控制器15可以用于根据汽车电瓶600的电压值输出控制信号，以控制汽车电瓶600为电源设备400充电，例如，在汽车电瓶600的电压大于电源设备400的电压且两者的电压差值大于预设差值时，汽车电瓶600可以通过电路结构10中的降压电路为电源组件410充电。在汽车电瓶600的电压大于电源设备400的电压且两者的电压差值小于预设差值时，汽车电瓶600可以直接为电源组件410充电。
在某些实施方式中，电路结构10包括负载反接控制电路175，负载反接控制电路175用于检测电源设备400与汽车电瓶600是否反接。
如此，能够通过负载反接控制电路175快速、准确地检测电源设备400与汽车电瓶600是否反接。电源设备400与汽车电瓶600反接，可以是指汽车电瓶600的第一极与电源组件410的第一极是相反的(一个是正极、另一个是负极)；汽车电瓶600的第二极与电源组件410的第二极也是相反的。另外，负载反接控制电路175还可以用于检测电源设备400与汽车电瓶600是否连接。
在某些实施方式中，在电源设备400与汽车电瓶600反接时，负载反接控制电路175还用于控制电子开关驱动电源171关闭，从而避免电源组件410错误地向汽车电瓶600放电。
在某些实施方式中，在电源设备400与汽车电瓶600反接时，由于此时电路连接异常，不需要检测是否打火、不需要控制第一开关14导通，因此控制器15可以控制采样模块 13保持断开。
在某些实施方式中，电路结构10包括提示元件176，提示元件176用于在电源设备400与汽车电瓶600反接时发出提示。
提示元件176可以为显示模块1762、振动元件、喇叭等，例如可以利用显示模块1762显示“正负极接反”的提示文字，也可以利用振动元件按预设规律振动，还可以利用喇叭播报“正负极接反”的提示声音。利用提示元件176提示信息可以便于用户快速、准确地掌握电源设备400的相关信息。
