请参考图 1， 其示出了本公开一个示例性实施例提供的电池保护系统的结构示意图。 该电池保护系统包括电池 10和电子设备 20。
电池 10包括可充放电源 110和电池芯片 120。
可充放电源 110用于向电子设备 20供电， 保证电子设备 20正常工作。
电池芯片 120用于检测可充放电源 110是否已经开始向电子设备 20供电， 若检测结 果为可充放电源 110已经开始向电子设备 20供电，则通过预定发送引脚向电子设备 20发 送定制信号。
电池 10和电子设备 20之间通过预定引脚相连。
电子设备 20用于识别电池 10发送的定制信号是否正确； 若定制信号不正确， 则控制 切断可充放电源 110的供电。 综上所述， 本实施例提供的电池保护系统， 通过电池向电子设备发送定制信号， 定制 信号用于由电子设备识别该定制信号是否正确； 若定制信号不正确， 则控制切断电池的供 电； 解决了相关技术中仿制电池可能会导致负面后果的问题； 达到了在保证使用的电池为 满足要求的原装电池的情况下， 才保持电池的供电， 同时提高了电池和电子设备的安全性 的效果。 请参考图 2， 其示出了本公开另一示例性实施例提供的电池保护系统的结构示意图。 该电池保护系统包括电池 10和电子设备 20。
通常， 电池 10包括四个引脚， 分别为： 电源正极 D+、 电源负极 D -、 温度检测引脚 T 和身份引脚 ID。 电源正极 D+与电源负极 D-分别和电子设备 20的正负极相连， 构成供电 回路， 给电子设备 20提供电能， 保证电子设备 20正常工作。 身份引脚 ID与电子设备 20 的 GPIO (General Purpose Input Output, 通用输入 /输出） 引脚相连， 向电子设备 20发送 定制信号。
电池 10包括可充放电源 110和电池芯片 120。
可充放电源 110用于向电子设备 20供电， 保证电子设备 20正常工作。
电池芯片 120用于检测可充放电源 110是否已经开始向电子设备 20供电， 若检测结 果为可充放电源 110已经开始向电子设备 20供电，则通过预定发送引脚向电子设备 20发 送定制信号。 本实施例中， 以预定发送引脚为身份引脚 ID来举例说明， 对此不作具体限 定。
电池芯片 120可以包括供电检测电路（图中未示出） ， 检测可充放电源 110是否已经 开始向电子设备 20供电。
电池芯片 120还包括振荡电路 122、 参考电压生成电路 124和比较器 126。
电池芯片 120内部的振荡电路 122用于产生正弦波信号；参考电压生成电路 124用于 生成预定参考电压。 正弦波信号与预定参考电压经比较器 126输出为定制信号， 比如， 定 制信号为 "0101010011 "的定制时序信号。 具体来讲， 比较器 126包含两个输入端和一个 输出端， 比较器 126的两个输入端分别与振荡电路 122和参考电压生成电路 124相连， 比 较器 126的输出端与预定发送引脚相连。比较器 126将正弦波信号与预定参考电压进行比 较后， 生成定制信号。 比如， 当正弦波信号的电压值大于预定参考电压时， 输出为高电平； 当正弦波信号的电压值小于或者等于预定参考电压时， 输出为低电平。振荡电路 122产生 的正弦波信号的频率、 幅值以及比较器 126 生成的预定参考电压均可以根据实际需求而 定。
另外， 参考电压生成电路 124 生成的预定参考电压在时域上可以是某一不变的电压 值， 或者在时域上是连续变化的电压值。 不同的预定参考电压经比较器 126输出的定制信 号均不相同。 当预定参考电压为某一不变的电压值时， 生成的定制信号可以是 " 10101 " ; 而当预定参考电压为连续变化的电压值时， 生成的定制信号可以是 " 11101 " 。 比较器 126输出的定制信号经电池 10的预定发送引脚，也即身份引脚 ID以及电子设 备 20的预定接收引脚， 也即 GPIO引脚， 由电子设备 20的处理器 210接收。
电子设备 20包括处理器 210和预定接收引脚，处理器 210用于识别电池 10发送的定 制信号是否正确； 若定制信号不正确， 则切断电池 10的供电。
比如， 可以在电子设备 20的处理器 210中预存一个 " 111111 " 的时序信号。 当电子 设备 20通过预定接收引脚接收到电池 10发送的 "0101010011 "的定制信号时， 经过与预 存的 " 111111 " 比对不相同， 说明电池 10发送的定制信号不正确。 处理器 210控制电子 设备 20切断电池 10的供电， 以保证供电的安全。 具体地， 可以在电子设备 20侧的供电 回路中设置一个开关， 当处理器 210识别发现定制信号不正确时， 控制供电回路中的开关 断开，从而实现切断电池 10的供电。只有当电子设备 20通过预定接收引脚接收到电池 10 发送的定制信号为 " 111111 "时， 处理器 210才保持电池 10的供电。
通常， 相同规格且相同型号的电池设置发送相同的定制信号， 不同规格或者不同型号 的电池设置发送不同的定制信号。 电子设备 20的处理器 210中可以预存两个或者两个以 上定制信号， 当电子设备 20接收到电池 10发送的定制信号时， 是要该定制信号和预存的 两个或者两个以上的定制信号中的一个相同， 则可通过验证。 这样， 电子设备 20就可以 兼容不同规格或者不同型号的电池。
需要说明的是， 为了节省电池 10的电能， 提高电池 10的使用时间。 在电子设备 20 的处理器 210经过识别电池 10发送的定制信号，且确定该定制信号正确之后，处理器 210 可以切断预定接收引脚与电池 10的预定发送引脚之间的连接，使得电池 10停止发送定制 信号。在第一种可能的实施方式中， 切断电子设备 20的预定接收引脚与电池 10的预定发 送引脚之间的电性连接； 或者， 在第二种可能的实施方式中， 在电子设备 20侧的接收定 制信号的回路中设置一个开关， 当确定定制信号正确后， 控制该开关断开。 对应地， 电池
10的电池芯片 120在检测到预定发送引脚与电子设备 20之间的连接断开时， 停止向电子 设备 20发送定制信号。
还需要说明的是， 对于一些未设置有定制信号发送功能的电池， 为了避免这些电池给 电子设备供电而产生负面后果。在电子设备开机初始化完成后的一个时间段， 也即预定时 间段内， 电子设备的处理器检测在该预定时间段内是否接收到电池发送的定制信号。若在 预定时间内没有接收到电池发送的定制信号，则电子设备的处理器控制电子设备切断电池 的供电。若在预定时间内接收到电池发送的定制信号， 则电子设备的处理器识别该定制信 号是否正确。
综上所述， 本实施例提供的电池保护系统， 通过电池芯片的预定发送引脚向电子设备 发送定制信号， 定制信号用于由电子设备识别该定制信号是否正确； 若定制信号不正确， 则控制切断电池的供电； 解决了相关技术中仿制电池可能会导致负面后果的问题； 达到了 在保证使用的电池为满足要求的原装电池的情况下， 才保持电池的供电， 同时提高了电池 和电子设备的安全性的效果。 本实施例提供的电池保护系统，还通过在电子设备的处理器验证定制信号正确的情况 下， 切断预定接收引脚与电池的预定发送引脚之间的连接， 达到了节省电池的电能， 提高 电池的使用时间的效果。 同时， 本实施例提供的电池保护系统， 还通过检测在预定时间段 内是否接收到电池发送的定制信号， 若在预定时间内没有接收到电池发送的定制信号， 则 电子设备的处理器控制电子设备切断电池的供电，避免了一些未设置有定制信号发送功能 的电池给电子设备供电而产生的负面后果。 请参考图 3， 其示出了本公开一个示例性实施例提供的电池保护方法的方法流程图。 该电池保护方法应用于图 1或图 2所示的电池保护系统中。该电池保护方法可以包括如下 步骤：

其中， 步骤 202至步骤 204可以单独实现成为电池侧的电池保护方法； 步骤 206至步 骤 208可以单独实现成为电子设备侧的电池保护方法
综上所述， 本实施例提供的电池保护方法， 通过电池芯片的预定发送引脚向电子设备 发送定制信号， 且通过电子设备的预定接收引脚接收电池发送的定制信号； 电子设备识别 该定制信号是否正确； 若定制信号不正确， 则控制切断电池的供电； 解决了相关技术中仿 制电池可能会导致负面后果的问题；达到了在保证使用的电池为满足要求的原装电池的情 况下， 才保持电池的供电， 同时提高了电池和电子设备的安全性的效果。 请参考图 4， 其示出了本公开另一示例性实施例提供的电池保护方法的方法流程图。 该电池保护方法应用于图 1或图 2所示的电池保护系统中。该电池保护方法可以包括如下 步骤：
在步骤 301中， 检测电池是否已经开始向电子设备供电。
电池检测自身是否已经开始向电子设备供电。 电池内部可以设置有供电检测电路， 检 测电池中的可充放电源是否已经开始向电子设备供电。 在步骤 302中， 若检测结果为电池已经开始向电子设备供电， 则产生正弦波信号。 若检测结果为电池已经开始向电子设备供电， 则电池产生正弦波信号。 电池的电池芯 片内部设置有振荡电路， 振荡电路用于产生正弦波信号。 在电池开始向电子设备供电后， 也即在电池的电源正极 D+与电源负极 D-分别和电子设备的正负极相连，构成供电回路后， 电池芯片通过振荡电路产生正弦波信号。
在步骤 303中， 生成预定参考电压。
电池生成预定参考电压。 电池的电池芯片内部还设置有参考电压生成电路， 参考电压 生成电路用于生成预定参考电压， 比如， 预定参考电压为 0。
在步骤 304中， 将正弦波信号与预定参考电压进行比较后， 生成定制信号。
电池将正弦波信号与预定参考电压进行比较后， 生成定制信号。 电池的电池芯片内部 还设置有比较器， 比较器将正弦波信号与预定参考电压进行比较后， 生成定制信号。 定制 信号可以是由 "0"和 " 1 "组成的定制时序信号， 比如 "0101010011 " 。 通常， 相同规格 且相同型号的电池设置生成相同的定制信号。
比如， 当正弦波信号的电压值大于预定参考电压时， 输出为高电平； 当正弦波信号的 电压值小于或者等于预定参考电压时， 输出为低电平。振荡电路 122产生的正弦波信号的 频率、 幅值以及比较器 126生成的预定参考电压均可以根据实际需求而定， 且预定参考电 压可以是一个实时变化的电压。
在步骤 305中， 通过电池的预定发送引脚向电子设备发送定制信号。
电池通过自身的预定发送引脚向电子设备发送定制信号。电池的电池芯片可以通过电 池的身份引脚 ID向电子设备发送定制信号， 而电子设备的处理器可以通过 GPIO引脚接 收电池发送的定制信号。
对应地， 电子设备通过预定接收引脚接收电池发送的定制信号， 该定制信号是在电池 开始向电子设备供电后发送的。
在步骤 306中， 识别定制信号是否正确。
电子设备识别定制信号是否正确。 比如， 可以在电子设备的处理器中预存一个
" 111111 " 的时序信号。 当电子设备通过预定接收引脚接收到电池发送的 "0101010011 " 的定制信号时， 经过与预存的 " 111111 " 比对不相同， 说明电池发送的定制信号不正确。
在步骤 307中， 若定制信号不正确， 则切断电池的供电。
若定制信号不正确， 则电子设备切断电池的供电。 当定制信号不正确时， 电子设备的 处理器切断电池的供电， 以保证供电的安全。 具体地， 可以在电子设备侧的供电回路中设 置一个开关， 当处理器识别发现定制信号不正确时， 控制供电回路中的开关断开， 从而实 现切断电池的供电。
在步骤 308中， 若定制信号正确， 则保持电池的供电， 并切断预定接收引脚与电池的 预定发送引脚之间的连接。
若定制信号正确， 则电子设备保持电池的供电， 并切断预定接收引脚与电池的预定发 送引脚之间的连接。 当电子设备通过预定接收引脚接收到电池发送的 " 111111 "的定制信 号时， 经过与预存的 " 111111 " 比对相同， 说明电池发送的定制信号正确。 此时， 电子设 备的处理器保持电池的供电， 并切断预定接收引脚与电池的预定发送引脚之间的连接。在 验证定制信号正确之后， 为了节省电池的电能， 提高电池的使用时间， 电子设备可以切断 预定接收引脚与电池的预定发送引脚之间的连接。
在第一种可能的实施方式中，切断电子设备的预定接收引脚与电池的预定发送引脚之 间的电性连接； 或者， 在第二种可能的实施方式中， 在电子设备侧的接收定制信号的回路 中设置一个开关， 当确定定制信号正确后， 控制该开关断开。
在步骤 309中， 在预定发送引脚与电子设备之间的连接断开时， 停止向电子设备发送 定制信号。
在预定发送引脚与电子设备之间的连接断开时， 电池停止向电子设备发送定制信号。 当预定发送引脚与电子设备之间的连接断开时， 电池的发送定制信号的回路断开， 电池停 止向电子设备发送定制信号。
需要说明的是， 对于一些未设置有定制信号发送功能的电池， 为了避免这些电池给电 子设备供电而产生负面后果。在电子设备开机初始化完成后的一个时间段， 也即预定时间 段内， 电子设备的处理器检测在该预定时间段内是否接收到电池发送的定制信号。若在预 定时间内没有接收到电池发送的定制信号，则电子设备的处理器控制电子设备切断电池的 供电。若在预定时间内接收到电池发送的定制信号， 则电子设备的处理器识别该定制信号 是否正确。
上述步骤 301至步骤 305以及步骤 309可以单独实现成为电池侧的电池保护方法；上 述步骤 306至步骤 308可以单独实现成为电子设备侧的电池保护方法。
