在上述的常规充电或快速充电过程中，主控制模块102通过终端的通信接口10与电源适配器400进行数据通信，并获取对电池200的充电电压和充电电流，如果上述的充电电压大于电压阈值和/或上述的充电电流大于电流阈值，则主控制模块102发送充电关断指令使控制器300关闭终端的通信接口10，如果上述的充电电压不大于电压阈值，且上述的充电电流不大于电流阈值，则主控制模块102继续获取上述的充电电压和充电电流。
基于图1所示的电池充电控制装置100，本发明实施例还可提供一种电池充电控制方法，如图2所示，该电池充电控制方法包括以下步骤：
S1．主控制模块102与外部的电源适配器400进行数据通信，并获取对电池200的充电电压和充电电流；

S8. 主控制模块102通过电池连接器101检测电池200的电量，并将电量信息反馈至控制器300。
图4示出了本发明实施例提供的电池充电控制装置的示例电路结构，为了便于说明，仅示出了与本发明实施例相关的部分，详述如下：
主控制模块102包括：
主控制器U6、第十三电容C13及第三十六电阻R36；
电池连接器101的第一脚5A-1与第二脚5A-2共接于地，电池连接器101的第一接地脚GND1和第二接地脚GND2共接于地，主控制器U6的第一输入输出脚RA0与电池连接器101的第七脚5A-3和第八脚5A-4连接，主控制器U6的第二输入输出脚RA1、第七输入输出脚RC0、第八输入输出脚RC1及第九输入输出脚RC2分别与电池连接器101的第六脚2A-4、第五脚2A-3、第四脚2A-2及第三脚2A-1连接，主控制器U6的模拟地脚VSS和地脚GND均接地，主控制器U6的第一空接脚NC0和第二空接脚NC1均空接，主控制器U6的电源脚VDD与第十三电容C13的第一端均与电池连接器101的第七脚5A-3和第八脚5A-4共接，主控制器U6的第四输入输出脚RA3和第十一输入输出脚RC4与控制器300连接，第三十六电阻R36连接于主控制器U6的第四输入输出脚RA3与电源脚VDD之间，主控制器U6的第五输入输出端RA4和第十输入输出端RC3分别为主控制模块102的第一开关控制端和第二开关控制端，主控制器U6的第六输入输出脚RA5和第十二输入输出脚RC5分别为主控制模块102的第一通信端和第二通信端。其中，主控制器U6具体可以是型号为PIC12LF1501、PIC12F1501、PIC16LF1503、PIC16F1503、PIC16LF1507、PIC16F1507、PIC16LF1508、PIC16F1508、PIC16LF1509或者PIC16F1509的单片机。
快充开关模块103包括：
第三十七电阻R37、第十四电容C14、第一肖特基二极管SD1、第二肖特基二极管SD2、第十五电容C15、第三十八电阻R38、第三十九电阻R39、第四十电阻R40、第三NPN型三极管N3、第四NMOS管Q4以及第五NMOS管Q5；
第十四电容C14的第一端为快充开关模块103的第一受控端，第三十七电阻R37的第一端与第三十八电阻R38的第一端的共接点为快充开关模块103的第二受控端，第三十七电阻R37的第二端与第一肖特基二极管SD1的阳极共接于第四NMOS管Q4的源极，第三十八电阻R38的第二端连接第三NPN型三极管N3的基极，第十四电容C14的第二端与第一肖特基二极管SD1的阴极共接于第二肖特基二极管SD2的阳极，第三十九电阻R39的第一端与第十五电容C15的第一端共接于第二肖特基二极管SD2的阴极，第三十九电阻R39的第二端与第四十电阻R40的第一端及第三NPN型三极管N3的集电极均连接第四NMOS管Q4的栅极和第五NMOS管Q5的栅极，第四十电阻R40的第二端与第十五电容C15的第二端共接于地，第四NMOS管Q4的源极为快充开关模块103的输出端，且与电池连接器101的第七脚5A-3和第八脚5A-4连接，第四NMOS管Q4的漏极连接第五NMOS管Q5的漏极，第五NMOS管Q5的源极为快充开关模块103的输入端，第三NPN型三极管N3的发射极连接第三肖特基二极管SD3的阳极，第三肖特基二极管SD3的阴极接地。
对于图4所示的电池充电控制装置，主控制器U6通过其第四输入输出脚RA3和第十一输入输出脚RC4与控制器300进行数据通信，主控制器U6将电池200的电压和电量信息传送给控制器300，且主控制器U6还可以根据电池200的电压判断电池200是否完成快速充电进程，如果是，则主控制器U6输出高电平使第三NPN型三极管N3导通以控制第四NMOS管Q4和第五NMOS管Q5关断；在对电池200进行充电的过程中，如果电源适配器400与电池200之间突然断开连接，主控制器U6会检测到对电池200的充电电压为零，然后输出高电平使第三NPN型三极管N3导通以控制第四NMOS管Q4和第五NMOS管Q5关断，并反馈充电关断指令控制器300关闭终端的通信接口10。另外，如果终端能够检测电池200的温度，并由控制器300在温度异常时反馈快充关闭指令给主控制器U6，主控制器U6根据该快充关闭指令输出高电平使第三NPN型三极管N3导通以控制第四NMOS管Q4和第五NMOS管Q5关断。
在对电池200进行快速充电时，快充开关模块103从终端的通信接口10引入直流电通过电池连接器101对电池200进行充电是由主控制器U6通过其第五输入输出脚RA4输出高电平控制第四NMOS管Q4和第五NMOS管Q5导通，并通过其第十输入输出脚RC3控制第三NPN型三极管N3关断，从而实现通过终端的通信接口10引入直流电对电池200进行充电，由于电池200本身就已经通过通信接口10从电源适配器400获得直流电，所以快充开关模块103从终端的通信接口10引入直流电通过电池连接器101对电池200进行充电可以起到增大对电池200的充电电流的作用，从而实现对电池200的快速充电。
另外，在对电池200进行快速充电时，如果终端的通信接口10的电源线VBUS和地线GND分别接地和直流电输入，即通信接口10出现电源反接，快充开关模块103的输入端接地，电池充电控制装置100中各模块内部的地接入直流电；为了避免造成元器件损坏，如图5所示，快充开关模块103还可以进一步包括第六NMOS管Q6、第七NMOS管Q7及第四十一电阻R41，第六NMOS管Q6的源极连接第五NMOS管Q5的源极，第六NMOS管Q6的漏极连接第七NMOS管Q7的漏极，第七NMOS管Q7的源极连接第三NPN型三极管N3的集电极，第六NMOS管Q6的栅极与第七NMOS管Q7的栅极共接于第四十一电阻R41的第一端，第四十一电阻R41的第二端接地。
当出现上述反接问题时，第四十一电阻R41的第二端从地接入直流电以驱动第六NMOS管Q6和第七NMOS管Q7关断，从而使从地进入电池充电控制装置100的直流电无法形成回路，从而达到保护元器件不受损坏的目的。
本发明实施例还提供了一种终端，其包括上述的通信接口10、控制器300、电池200及上述的电池充电控制装置100。
综上所述，本发明实施例通过采用包括电池连接器101、主控制模块102及快充开关模块103的电池充电控制装置100，在对终端中的电池200进行常规充电或快速充电过程中，主控制模块102通过终端的通信接口10与外部的电源适配器400进行数据通信并获取对电池200的充电电压和充电电流，如果上述的充电电压大于电压阈值和/或上述的充电电流大于电流阈值，则主控制模块102发送充电关断指令使终端的控制器300关闭终端的通信接口10，从而达到了对电池200实现过压和/或过流保护的目的。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
