Description

一种电池过放电警示方法、装置、电池及飞行器 技术领域
本发明实施例涉及电池技术领域，特别是涉及一种电池过放电警示方法、装置、电池及飞行器。
背景技术
电池在使用的过程中随着放电的进行，电芯电压会逐步下降，当电芯电压降低到一定电压值的时候应该停止放电，然后对其充电以恢复储电能力。如果放电过程中电芯电压低到一定值后依然没有停止放电，就会发生过度放电，即过放电，过放电的发生，尤其是深度过放电的发生会给电池本身带来一些不可逆的损伤，从而导致电池寿命缩短，同时影响电池的正常使用。
一般的，无人机电池针对过放电都会做一些保护措施，但是在无人机飞行的过程中，为了尽可能的保证无人机的安全，针对电池过放电的保护策略都比较谨慎。所以如果无人机在飞行过程中，因为人为的一些操作，导致没有及时返航，或者其他不正常的操作，都极有可能导致电池在飞行的过程中发生过放电。在多次过放电以后，电池的性能会发生很大的变化，极易发生电量突变进而导致炸机。

基于上述描述，下面结合附图对本发明实施例作进一步阐述。
实施例1
请参阅图5，图5为本发明实施例提供的一种电池过放电警示方法的示意图，电池用于为移动平台供电，该方法应用于电池或移动平台，方法包括：
步骤110：在电池的放电过程中，判断电池的电压是否低于电池发生过放电的电压临界值。
可以理解的是，电池的电压或电池电压，即为电池中各个电芯的电压中最小的电压值。通常电池包括至少一个电芯，也即电池中的电芯的数量可以是一个或者更多个，至少一个电芯中的各个电芯可以通过串联、并联或串并联连接从而形成具有足够能量和电力的能量存储单元，以执行电池的预期功能。例如，以飞行器的电池为例，通过至少一个电芯中的各个电芯的串联、并联或串并联连接为飞行器系统中的各个系统提供电力。
由于只要电池中的任何一个电芯的特性出现差异，就会对整个电池的性能造成影响，因此，为准确监测电池在放电过程中的状态，本发明实施例在电池的放电过程中，电池的控制芯片或移动平台的主控芯片会实时监测各个电芯的电压，并确定各个电芯的电压中最小的电压值，以 该值作为电池的电压。
例如，电池的电芯包括有：“电芯1”、“电芯2”、“电芯3”及“电芯4”，若在电池放电过程中的某个时刻(可以为电池放电过程中的任意时刻)，获取得到的“电芯1”的电压为4.48V，“电芯2”的电压为3.64V，“电芯3”的电压为4.24V，“电芯4”的电压为4.22V，则该时刻电池的电压为3.64V。
进一步，电池的控制芯片或移动平台的主控芯片会将电池放电过程中电池的电压与电池发生过放电的电压临界值进行比较，以确定在电池放电过程中是否发生过放电。
在一实施例中，电池发生过放电的电压临界值为电芯的放电截止电压。放电截止电压指在进行放电的过程中，电压下降到不宜再继续放电的最低工作电压。根据不同的电池类型及不同的放电条件，对电池的容量和寿命的要求不同，电芯的放电截止电压也不相同。电池发生过放电的电压临界值可以是预先配置的，也可以是根据需要进行自定义设置的。
以锂电池为例，为了兼顾到电池的寿命、容量、和安全性，锂电池的电芯放电时存在电压下限，当电芯电压低于2.4V时，部分材料会开始被破坏。又由于电芯会自放电，放电愈久电压会愈低，因此，放电时最好不要放到2.4V才停止。锂电池电芯从3.0V放电到2.4V这段期间，所释放的能量只占电池容量的3％左右，因此，通常3.0V是一个理想的放电截止电压。也即，在一些实现方式中，电池发生过放电的电压临界值可以为3.0V。
在另一些实现方式中，为了保守起见，电池发生过放电的电压临界值还可以略大于3.0V，例如，电池发生过放电的电压临界值为3.2V。
步骤120：如果电池的电压低于电池发生过放电的电压临界值，记录电池在放电过程中出现的最小电压值，以用于形成最小电压值记录。
当电池的控制芯片或移动平台的主控芯片判断出电池的电压低于电池发生过放电的电压临界值时，便可确定电池发生过放电，开始缓存过放电过程中各个时刻的电池电压。具体地，电池的控制芯片或移动平台的主控芯片以预设的监测频率对各个电芯的电压进行监测，其中，该 预设的监测频率可以根据需要进行设置。例如，该预设的监测频率为1Hz，即对各个电芯的电压每1S进行一次监测，在监测过程中获取电池在每秒的电压。
需要说明的是，可以缓存每次获取到的电池电压，也可以将当前获取的电池电压与上一次获取的电池电压进行比较，只记录电压值较小的一个电压。
例如，若在电池过放电过程中的开始时刻，获取得到的“电芯1”的电压为3.20V，“电芯2”的电压为3.05V，“电芯3”的电压为2.96V，“电芯4”的电压为2.88V，则开始时刻电池的电压为“电芯4”的电压2.88V。若在电池过放电过程中的第1S时刻，获取得到的“电芯1”的电压为3.02V，“电芯2”的电压为3.02V，“电芯3”的电压为2.82V，“电芯4”的电压为2.88V，则该时刻电池的电压为“电芯3”的电压2.82V，缓存的电压数据中可以包括2.88V、2.82V，也可以只包括2.82V
在电池放电结束后，根据缓存的电压数据确定电池在过放电过程中出现的最小电压值，该值亦为电池在整个放电过程中的最小电压值。
如上所述，电芯会自放电，实际上在电池的整个寿命中电池都是处于放电状态，本领域技术人员可以理解，本实施例所述的电池放电结束即为接收到电池关机信号。
当每次获取的电池电压都有记录时，通过比较各电压值可得到电池该次过放电过程中出现的最小电压值；当只缓存电压值较小的一个电压时，最后一次缓存的电压值即为电池该次过放电过程中的最小电压值。记录电池在过放电过程中出现的最小电压值，以用于形成最小电压值记录。
需要说明的是，在电池的放电过程中，判断电池的电压是否低于电池发生过放电的电压临界值不是必需步骤。在另一实施例中，在电池的放电过程中，可以直接缓存放电过程中各个时刻的电池电压，在电池放电结束后，根据缓存的电压数据确定电池在放电过程中出现的最小电压值，并记录电池在放电过程中出现的最小电压值。
步骤130：存储电池在历次放电过程中出现的最小电压值，以形成 电压最小值记录。
将电池每一次放电过程中出现的最小电压值存储在电池的控制芯片中，或者存储在移动平台的主控芯片中，以形成电压最小值记录，以便为电池的安全性能的评估提供依据。
芯片中的存储器通常包括易失性存储器(random access memory，RAM)和非易失性存储器(如，flash存储器)，在实际应用中，监测过程中各个电芯的电压、电池的电压均可以存储在易失性存储器中，而电池发生过放电的电压临界值、放电过程中出现的最小电压值均可以存储在非易失性存储器中，在断电后不会丢失。
步骤140：接收电池开机信号。
步骤150：获取电池的最小电压值记录，最小电压值记录是指电池在历次放电过程中出现的最小电压值的集合。
步骤160：根据最小电压值记录，获取电池的过放电损伤次数。
具体地，根据最小电压值记录，获取电池的过放电损伤次数，包括：将最小电压值记录中的每一个最小电压值与预设过放电判损值比较；统计最小电压值记录中，最小电压值小于预设过放电判损值的次数，以得到电池的过放电损伤次数。
其中，预设过放电判损值小于电池发生过放电的电压临界值。预设过放电判损值被定义为当电池的电压低于该值时电池会受到不可逆损伤的临界值，根据不同的电池类型及不同的放电条件，对电池的容量和寿命的要求不同，电池的预设过放电判损值也不相同，预设过放电判损值可以是预先配置的，也可以是根据需要进行自定义设置的。
本实施例中，预设过放电判损值为电池发生过放电的电压临界值的50％，例如，电池发生过放电的电压临界值为3.0V，则预设过放电判损值为1.5V。在其他实施例中，为了保守起见，预设过放电判损值还可以略大，如，预设过放电判损值为电池发生过放电的电压临界值的60％，或者，为了提高电池的使用率，预设过放电判损值还可以略小，如，预设过放电判损值为电池发生过放电的电压临界值的40％。
基于电池在历次放电过程中出现的最小电压值和预设过放电判损 值可得到电池的过放电损伤次数。示例性地，预设过放电判损值为1.5V，电池在历次过放电过程中出现的最小电压值分别为1.25V、1.38V、1.6V、2.34V，则统计得到的电池的过放电损伤次数为两次。
步骤170：根据电池的过放电损伤次数，进行电池过放电警示。
具体地，当电池的过放电损伤次数大于等于预设值时，电池或移动平台进行电池过放电警示，移动平台和/或用户可根据该警示做出相应的响应和操作，确保移动平台使用过程中的安全性。具体实施时，过放电警示可以包括一级预警提示、二级预警提示、三级预警提示等，过放电损伤次数越多，预警提示的级别越高，表示电池存在的安全隐患越大。
本实施例通过存储电池在放电过程中出现的最小电压值，形成电压最小值记录，以及在接收电池开机信号之后，通过获取电池的最小电压值记录，根据最小电压值记录，获取电池的过放电损伤次数，根据电池的过放电损伤次数，进行电池过放电警示，能够根据电池过放电发生的程度和次数给出警示，以使移动平台和/或用户根据该警示做出相应的响应和操作，确保移动平台运行过程中的安全性。
实施例2
请参阅图6，图6为本发明实施例提供的另一种电池过放电警示方法的示意图，电池用于为移动平台供电，该方法应用于电池或移动平台，方法包括：
步骤210：在电池的放电过程中，判断电池的电压是否低于电池发生过放电的电压临界值。
步骤220：如果电池的电压低于电池发生过放电的电压临界值，获取电池在放电过程中出现的最小电压值，并判断最小电压值是否低于预设过放电判损值。
判断电池的电压是否低于电池发生过放电的电压临界值，以及获取电池在放电过程中出现的最小电压值可参考实施例1。
同样地，在电池的放电过程中，判断电池的电压是否低于电池发生过放电的电压临界值不是必需步骤。在另一实施例中，在电池的放电过 程中，可以直接缓存放电过程中各个时刻的电池电压，在电池放电结束后，根据缓存的电压数据获取电池在放电过程中出现的最小电压值。
其中，预设过放电判损值小于电池发生过放电的电压临界值。预设过放电判损值被定义为当电池的电压值低于该值时会受到不可逆损伤的临界值，根据不同的电池类型及不同的放电条件，对电池的容量和寿命的要求不同，电池的预设过放电判损值也不相同，预设过放电判损值可以是预先配置的，也可以是根据需要进行自定义设置的。
本实施例中，预设过放电判损值为电池发生过放电的电压临界值的50％，例如，电池发生过放电的电压临界值为3.0V，则预设过放电判损值为1.5V。在其他实施例中，为了保守起见，预设过放电判损值还可以略大，如，预设过放电判损值为电池发生过放电的电压临界值的60％，或者，为了提高电池的使用率，预设过放电判损值还可以略小，如，预设过放电判损值为电池发生过放电的电压临界值的40％。
通过比较电池放电过程中出现的最小电压值和预设过放电判损值的大小，可判断本次放电是否会对电池造成不可逆损伤。
步骤230：如果最小电压值低于预设过放电判损值，将电池的过放电损伤次数递增一次，记录更新后的过放电损伤次数。
在电池的控制芯中，或者在移动平台的主控芯片器中，存储有电池的过放电损伤次数，以便为电池的安全性能的评估提供依据。
芯片中的存储器通常包括易失性存储器(random access memory，RAM)和非易失性存储器(如，flash存储器)，在实际应用中，监测过程中各个电芯的电压、电池的电压、最小电压值均可以存储在易失性存储器中，而电池发生过放电的电压临界值、预设过放电判损值、电池的过放电损伤次数均可以存储在非易失性存储器中，在断电后不会丢失。
如果电池放电过程中出现的最小电压值小于预设过放电判损值，将电池的过放电损伤次数在原有值的基础上递增一次，同时也将更新后的过放电损伤次数替代原有值存储在非易失性存储器中。
步骤240：接收电池开机信号。
步骤250：获取电池最新的过放电损伤次数。
步骤260：根据电池的过放电损伤次数，进行电池过放电警示。
具体地，当电池的过放电损伤次数大于等于预设值时，电池或移动平台进行电池过放电警示，移动平台和/或用户可根据该警示做出相应的响应和操作，确保移动平台使用过程中的安全性。具体实施时，过放电警示可以包括一级预警提示、二级预警提示、三级预警提示等，过放电损伤次数越多，预警提示的级别越高，表示电池存在的安全隐患越大。
本实施例通过存储电池的过放电损伤次数，以及在接收电池开机信号之后，通过获取电池的过放电损伤次数，根据电池的过放电损伤次数，进行电池过放电警示，能够根据电池过放电发生的程度和次数给出警示，以使移动平台和/或用户根据该警示做出相应的响应和操作，确保移动平台运行过程中的安全性。

本实施例中，电池开机包括：电池与移动平台建立电连接。
步骤330：获取电池的过放电损伤次数，其中，过放电损伤次数基于电池在历次放电过程中出现的最小电压值和预设过放电判损值得到，预设过放电判损值小于电池发生过放电的电压临界值。
电池发生过放电的电压临界值可以为电芯的放电截止电压，或者略大于电芯的放电截止电压。放电截止电压指在进行放电的过程中，电压下降到不宜再继续放电的最低工作电压，而预设过放电判损值被定义为当电池的电压值低于该值时会受到不可逆损伤的临界值。
电池发生过放电的电压临界值和预设过放电判损值均可以是预先配置的，也可以是根据需要进行自定义设置的。
需要说明的是，通常电池包括至少一个电芯，本实施例所述的最小 电压值，即为单个电芯的最小电压值。如何获取电池放电过程中电池的最小电压值，以及基于电池在历次放电过程中出现的最小电压值和预设过放电判损值得到电池的过放电损伤次数，可参考实施例1和实施例2，其在本领域技术人员容易理解的范围内，在此不再赘述。

其中，移动平台包括定位装置和动力装置，通过定位装置可获取移动平台的当前位置，通过动力装置可控制移动平台的移动位置。当电池的过放电损伤次数大于等于第一预设次数且小于第二预设次数时，需限制移动平台的移动区域，以便在移动平台出现意外状况的时候可以及时止损。
示例性地，当移动平台为飞行器时，二级预警提示用于限制其飞行高度和/或飞行距离。
步骤360：当电池的过放电损伤次数大于或等于第二预设次数时，进行三级预警提示，三级预警提示用于禁止移动平台启动。
当电池的过放电损伤次数大于等于第二预设次数时，说明电池过放电的程度和次数较高，存在严重的安全隐患，移动平台在接收到三级预警提示后，禁止其自身启动，避免不安全的事情发生。
在一些实施例中，电池还包括显示装置，则方法还包括：在电池的 显示装置上显示过放电警示和/或过放电损伤次数。例如，第一预设次数为3次，第二预设次数为7次，获取电池的过放电损伤次数为1次时，在电池的显示装置上显示一级预警提示和/或1次；获取电池的过放电损伤次数为5次时，在电池的显示装置上显示二级预警提示和/或5次；获取电池的过放电损伤次数为7次时，在电池的显示装置上显示三级预警提示和/或7次。
