【背景技术】
无人飞行器是一种对安全性要求比较高的产品，而电池作为无人飞行器安全的核心，在无人飞行器安全设计中显得尤为重要。锂电池由于具有重量轻、能量密度大的特点，所以在无人机领域得到广泛使用。锂电池也存在一些天然的缺陷，比如：受环境温度影响较大，对充放电电压要求较高等。其中，过放电问题一直是锂电池的一个常见问题，尤其是无人机、航模电池因放电倍率较高，电池内部化学活性较大，从而导致自放电速率较普通锂电池偏高很多，过放电的风险也会更高。
锂电池的电压一旦低于2伏特以下，就会存在不可逆的化学反应，导致电池鼓胀，容量降低，内部析锂等问题，会严重影响电池的安全性。目前针对电池过放电的问题，传统的做法是降低功耗或报废提示，然而降低功耗不能杜绝电池自身的自耗电，时间足够长之后就会使电池放到2伏特以下；报废提示也并没有强制限制用户的再次使用。以上两种做法都存在一定的安全风险。

图1为本发明实施例提供的应用环境示意图。如图1所示，所述应用环境包括电池10、电池保护模块20以及微处理器30。
电池10由一个或者多个电芯组成，以任何形式排列形成的电芯组，用于为电动机等电器设备提供直流电源。电池10可以根据实际情况，具有相应的容量、体积大小或者封装形式。电池10可以在受控的情况下放电或者充电，模拟正常的工作运行情况。
电池保护模块20可以是集成芯片，也可是外围电路，通过采集相应的数据来计算确定电池当前的电量、电流和电压等情况。该电池保护模块20还可以运行有一种或者多种合适的软件程序，记录数据并基于这些数据进行运算。
电池保护模块20与电池10之间建立有必要的电性连接，电池保护模块20包括电流采样电路，电压采样电路，温度采样电路，电池状态反馈电路、主回路控制电路等)，电池保护模块20通过这些电性连接采集、获取电池10的数据以确定电池10当前的电量、电流、电压等电性能参数、确定电池状态 (放电状态、休眠状态或待机状态)等，并实现相关保护功能(如短路保护，过流保护、过压保护、过温保护等)。
微处理器30与电池保护模块20之间通信连接，微处理器30可以根据电池保护模块20传输的相关电性能参数对相关保护功能的开启或关闭进行控制。如微处理器30可以向电池保护模块20发送电池休眠指令，微处理器30还可以在电池10过放电时，发出报废电池提示等。电池保护模块20在监测到微处理器30发出的电池休眠指令后，会结合电池10的电性能参数对电池10的充电和放电进行控制，其方式主要是控制主回路上的开关管的截止与导通。
实施例一：
图2为本发明实施例提供的无人飞行器电池安全处理方法流程示意图，同时结合图1一起对实施例一中的技术方案进行描述。如图2所示，该无人飞行器电池安全处理方法包括：
步骤S110：采集电池的电性能参数，所述电性能参数包括电池的放电电流值和单节电池电压值。
在本实施例中，出现的“电流值”只是一个数值，无正负之分，其前面的充电和放电则用于表示电流的方向。
在本实施例中，单节电池电压值是指多节电池中，其中一节电池电压值。电性能参数的采集一般通过电池保护模块20中相应的采样电路就可以完成。
步骤S120：根据所述电性能参数判断所述电池是否过放电，若是，则执行步骤S130。
在一个实施例中，电池保护模块20根据采集到的所述电性能参数确定单节电池电压值小于第一电压阈值且持续时间大于第一预设时间时，判断电池10是过放电。
在一个实施例中，第一电压阈值为2伏特，第一预设时间为20秒。
通常情况下，当单节电池电压值为2伏特时，已经是属于一个极限值了，因为再继续放电，电池基本就报废了，而将第一预设时间设为20秒，是为了足够时间确定单节电池电压值为2伏特。
可以理解，在其他实施例中，第一电压阈值还可以为其他值，比如2.1伏 特、2.2伏特、2.3伏特等，这里不作严格限定。同样地，第一预设时间也可以为其他值，比如19秒，21秒等，这里不作严格限定。
步骤S130：控制所述电池无法充电和放电。
在一个实施例中，控制所述电池无法充电和放电主要通过电池保护模块20关闭充电回路和放电回路，即控制主回路上的开关管的截止或导通。
与现有技术相比较，本发明实施例的无人飞行器电池安全处理方法，通过根据采集到的电池的电性能参数来判断电池是否过放电，并在确定电池过放电的情况下控制电池无法充电和放电，这样可以有效杜绝因严重过放电而导致的电池安全风险，提高了电池的可靠性。
实施例二：
请参阅图3，在一个实施例中，上述实施例一中的步骤S120之前还包括：
步骤S112：检测电池的休眠指令。
电池的休眠指令一般是由微处理器30发出的。微处理器30可以在电池的电性能参数的数值达到一定阈值或者在电池的电性能参数的数值达到一定阈值所持续的时间满足预设的时间值来自动发出休眠指令；微处理器30还可以根据用户的外部操作指令发出休眠指令，对此，这里不作严格限定。
步骤S114：根据所述电性能参数和检测结果确定电池状态。
在一个实施例中，电池保护模块20可以先根据所述电性能参数和检测结果确定电池状态。电池状态一般包括放电状态、充电状态、休眠状态和待机状态。在本实施例中，电池状态包括放电状态、休眠状态和待机状态，即确定的电池状态会是放电状态、休眠状态或待机状态。因为充电状态不会存在过放电情况，无需用到本实施例的技术方案。
具体地，在一个实施例中，需要将所述电池的放电电流值与第一电流阈值比较，将所述单节电池电压值与所述第二电压阈值比较，其中所述第一电流阈值为30毫安培，所述第二电压阈值为2.3伏特。
因为当放电电流值小于30毫安培时，有可能是受一些反向电流的干扰，不一定是真正的放电，通过该步骤，可以过滤掉一些干扰的情况。可以理解，在其他实施例中，第一电流阈值还可以在30毫安培左右浮动，如29毫安培、31毫安培等，这里不作严格限定。
在本实施例中，第二电压阈值大于第一电压阈值，因为第一电压阈值是电池报废的条件，而第二电压阈值主要是为了让电池进入低功耗的休眠状态。可以理解，在其他实施例中，第二电压阈值不限于2.3伏特，这里不作严格限定。
当所述电池的放电电流值大于所述第一电流阈值时，确定所述电池状态为放电状态。
在一个实施例中，当电池的放电电流值大于30毫安培时，可以确定所述电池状态为放电状态。
当所述电池的放电电流值小于或等于所述第一电流阈值且没有检测到有电池的休眠指令时，确定所述电池状态为待机状态。
在一个实施例中，当电池的放电电流值小于或等于30毫安培时，且电池没有休眠时，确定电池状态为待机状态。
当所述单节电池电压值小于第二电压阈值的持续时间大于第二预设时间或检测到有电池的休眠指令时，确定所述电池状态为休眠状态。
在一个实施例中，第二预时间为10秒。当单节电池电压值小于2.3伏特的持续时间大于10秒或已检测到电池的休眠指令时，确定电池状态为休眠状态。
在一个实施例中，当电池状态为休眠状态时，还会实时检测外部唤醒指令，当有外部唤醒指令时，会先关闭其充电回路和放电回路。以避免充电器给电池充电使电池电压升高从而影响判断。
实施例三：
请参阅图4，在一个实施例中，上述实施例一的基础上，步骤S130之后还包括：
S140：发出报废电池提示。
在一个实施例中，报废电池提示可以是灯光显示，可以是语音提示又或者是两者结合等，这里不作限制。
下面结合一个具体的可选实施例进行说明，如图5所示，首先在电池初始化后会确定电池状态，本实施例中需要确定电池状态为放电状态、休眠状 态还是待机状态。在这个确定的过程中电池保护模块中相应的采样电路会采集电池的电性能参数，所述电性能参数包括电池的放电电流值和单节电池电压值。
(1)如果检测到有放电电流，且确定放电电流值大于30毫安培就确定电池进入放电状态，在电池进入放电状态之后，电池保护模块会实时跟踪单节电池电压的情况，当其中任意一节电池电压小于2.0伏特且持续时间大于20秒时，电池则会进入报废模式，即电池保护模块会关闭主回路的输入和输出以控制电池无法充电和放电，同时微处理器还会发出报废电池指示，如声音提示，灯光提示等。如果电池在放电状态下，没有出现单节电池电压小于2.0伏特且持续时间大于20秒的情况，则继续保持放电状态。
(2)如果检测到有放电电流，且确定放电电流值小于或等于30毫安培且电池没有休眠时，就会确定电池为待机状态，在电池进入待机状态之后，电池保护模块会实时跟踪单节电池电压的情况，当其中任意一节电池电压小于2.0伏特且持续时间大于20秒时，电池则会进入报废模式，即电池保护模块会关闭主回路的输入和输出以控制电池无法充电和放电，同时微处理器还会发出报废电池指示，如声音提示，灯光提示等。如果电池在待机状态下，没有出现单节电池电压小于2.0伏特且持续时间大于20秒的情况，则继续保持待机状态。
(3)如果电路保护模块有检测到微处理器发出的休眠命令，或者有任意一节电池电压小于2.3伏特且持续时间大于10秒时，就确定电池进入休眠状态，即会关闭主回路输入和输出进入超低功耗状态。进行休眠状态之后的电池必须要借助充电器或者微处理器控制外部唤醒电路进行外部唤醒之后才能唤醒电路保护模块。当电路保护模块被唤醒之后，会先关闭主回路输入和输出，以避免充电器给电池充电使电池电压升高而影响判断。接着，电池保护模块会继续实时跟踪单节电池电压的情况，当任意一节电池电压小于2.0伏特且持续时间大于20秒时，电池则会进入报废模式，即电池保护模块会关闭主回路的输入和输出以控制电池无法充电和放电，同时微处理器还会发出报废电池指示，如声音提示，灯光提示等。如果电池在休眠状态下，没有出现单节电池电压小于2.0伏特且持续时间大于20秒的情况，则电池会进入待机状态。
这里设置第一电压阈值为2.0伏特和第一预设时间20秒这两个节点值，主要由于单节电池电压在2.0伏特左右的时候电池几乎接近报废，而因为一旦进入报废模式，电池就不能再用了，所以20秒用于保证电池完全没电。
这里设置第二电压阈值为2.3伏特和第二预设时间10秒这两个节点值，主要由于单节电池电压在2.3伏特左右的时候已经属于低电量了，这时需要进入低功耗的休眠模式，不然很快也要报废了。而设置10秒这个值，一方面为了足够长以防止误判结果的发生，但这个时间又不能太长，否则电池的电压会消耗得很快。
可以理解，第一电压阈值、第一预设时间、第二电压阈值、第二预设时间都不限于上述值，只要保证第二电压阈值大于第一电压阈值就可以了。
通过以上电池保护模块和微处理器的相互配合，可完成放电状态、待机状态以及休眠状态下对电池的监测，以保证在电池需要报废的情况下立即执行，降低电池的安全隐患。
