具体实施方式
下面将结合本发明实施例中附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。

随着动力电池的大规模退役，规范合理地回收动力电池成为大家关注的重点，每年数万吨的退役动力电池一旦处理不当，将会对环境造成不可估量的污染。
目前，我国对于退役动力电池的处理方式主要采用的回收方式是再生利用和梯次利用。现有技术在确定退役动力电池的回收方式时，主要考虑电池剩余容量、内阻和外部损伤的情况，从未考虑碳排放量维度。因此，最终确定的退役电池回收方式可能会产生较大的碳排放量，造成环境污染。
基于此，本发明实施例提供了一种电池的回收方式确定方法、装置、电子设备和存储介质。通过比较再生利用和梯次利用的电池单次充放电的碳排放量，选择碳排放量小的回收方式进行电池回收，从而将退役电池加工成低碳电池产品，满足储能企业、新能源汽车厂商对低碳产品的需求，最终实现低碳环保。
下面结合附图对本发明的各实施例进行详细说明。
本发明实施例提供的电池的回收方式确定方法及装置可以应用在电子设备中。本方案确定电池的回收方式时主要考虑的是低碳环保，通过比较再生利用和梯次利用的电池单次充放电的碳排放量，选择碳排放量小的回收方式进行电池回收。而碳排放量受如电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量和回收工艺碳排放量等因素的影响，因此，需要提前在电子设备上预置常见电池的电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量和回收工艺碳排放量等参数。
本发明实施例提供的电池的回收方式确定方法及装置应用于电子设备，由电子设备执行本发明实施例提供的电池的回收方式确定方法。在本发明实施例中，电子设备可以是，但不限于，个人电脑(PC机)、笔记本电脑或者服务器等具有数据计算分析处理能力的电子设备。
下面，基于电子设备中已预置常见电池的电池类型对应的电池预设参数对本发明实施例提供的电池的回收方式确定方法进行说明。请参照图1，图1示出了本发明实施例提供的电池的回收方式确定方法的一种示意图，该方法包括以下步骤：
步骤S101，获得待确定电池的电池类型，确定与电池类型对应的电池预设参数；
其中，电池预设参数中包含电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量和回收工艺碳排放量。
在本发明实施例中，电子设备中预存常见电池类型的预设参数，预设参数中包含但不限于电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量和回收工艺碳排放量。
当指定电池进行电池的回收方式确定时，首先获得待确定电池的电池类型，再根据电池类型找到与之匹配的电池预设参数。
步骤S102，根据电池类型、电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量，得到电力损耗碳排放量，电力损耗碳排放量为电池充放电过程中损耗电力产生的碳排放量。
在本发明实施例中，首先，电子设备根据电池额定容量和电池容量保持率得到电池实际容量，电池实际容量指的是当前电池充电时所消耗的电能。再根据电池实际容量和电池充放电效率得到电池充放电过程中损耗的电能。最后再根据电池充放电过程中损耗的电能和电力排放因子得到电力损耗碳排放量。
需要说明的是，其中，电池容量保持率用于表征当前电池容量和电池额定容量的比率。电池充放电效率用于表征电池放出的电能和电池充电消耗的电能的比率。电池额定容量用于表征电池出厂时的电池容量，可以但不限于通过扫描电池二维码的方式获取。电池循环次数用于表征电池的充放电次数。
在实际应用中，电力损耗碳排放量还可以通过计算公式所得：
E损耗＝Σ(AD充电-AD放电)×EF
其中，E损耗为电池运行过程中因充放电效率引起的电力损耗产生的碳排放量，AD充电为电池充电消耗的电能，AD放电为电池放出的电能，EF为电力排放因子，可以取国内电网排放因子0.5810tCO2/MWh。
步骤S103，根据电力损耗碳排放量、回收工艺碳排放量和电池循环寿命，分别得到再生利用和梯次利用的电池单次充放电的碳排放量。
在本申请实施例中，电池经过再生利用处理后是厂家出厂的新电池，此时电池循环寿命是电池出厂到电池退役时所剩余的电池充放电次数，而经过梯次利用处理后的电池，其电池循环寿命指的是从电池退役到没有梯次利用价值时所剩余的电池充放电次数。
其中，根据电力损耗碳排放量和回收工艺碳排放量可以获得电池生命周期内产生的碳排放量，再结合电池循环寿命可以得到再生利用和梯次利用的电池单次充放电的碳排放量。
步骤S104，比较再生利用和梯次利用的电池单次充放电的碳排放量，选择碳排放量小的方式作为待确定电池的目标回收方式。
可见，本实施例提供的电池的回收方式确定方法在电子设备中获得待确定电池的电池类型，确定与电池类型对应的电池预设参数；电池预设参数中包含电池循环次数、电池循环寿命、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量和回收工艺碳排放量。根据电池类型、电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量，得到电力损耗碳排放量，电力损耗碳排放量为电池充放电过程中损耗电力产生的碳排放量。根据电力损耗碳排放量、回收工艺碳排放量和电池循环寿命，分别得到再生利用和梯次利用的电池单次充放电的碳排放量。比较再生利用和梯次利用的电池单次充放电的碳排放量，选择碳排放量小的方式作为待确定电池的目标回收方式。从而将退役电池加工成低碳电池产品，满足储能企业、新能源汽车厂商对低碳产品的需求，最终实现低碳环保。
可选地，对于上述示例中提到的电池类型对应的电池预设参数，对于本方案的执行设备，用户可以通过交互界面或第三方服务器，进行参数的预置。在一种可能的实现方式中，在图1的基础上，参见图2，在步骤S101之前，还包括：
分别预置每种电池类型对应的电池循环次数、电池额定容量、电池类型、回收工艺碳排放量、电力排放因子、电池容量保持率和电池充放电效率；
其中，电池容量保持率和电池充放电效率通过多种电池类型的采样数据拟合确定。
具体的，采样数据可以为：电池循环寿命、电池循环次数、电池充放电效率等。在电池回收时，先将回收的电池包进行深度放电使电压低于安全拆解电压，之所以需要深度放电是为了防止电池包带电拆解可能引起人员伤害以及拆解过程中因破坏电池引起的自燃。将放电后的电池包使用拆解设备进行拆解，得到电池模组，或进一步将电池模组拆解为电池单体。使用充放电测试仪测试检测电池充放电效率、电池内阻、电池循环次数等性能情况，并抽样检测电池从退役到容量保持率降为10％以下的使用情况下的循环次数及充放电效率等信息，形成电池循环次数的采样数据。并对形成的电池生命周期采样数据进行计算拟合，确定电池的容量保持率和电池的充放电效率。
可选地，在实际应用中，电池充放电中的电力损耗受电池充放电效率影响，而电池充放电效率又与电池循环次数有关，电池充放电效率和电池循环次数满足以下关系：
z＝1.0944x-0.0245
其中，z为电池充放电效率，x为电池循环次数。
对于本方案涉及的电池充放电效率与电池循环次数，可以为在执行本方案前，通过对不同电池类型的电池的充放电数据进行统计汇总，分别获得每个电池类型对应的经验值。
在本发明实施例中，电池充放电效率是根据电池循环次数的采样数据拟合确定的。如图3所示，随着电池使用次数的增多，电池充放电效率会降低，电池放电能力下降。
可选地，在实际应用中，电池实际容量受电池容量保持率影响，而电池容量保持率又与电池循环次数有关，下面以三种电池类型为例具体说明，第一电池类型、第二电池类型和第三电池类型三种电池类型的电池容量保持率和电池循环次数满足以下关系：
yA＝-1.3577×10-8×x3+3.3137×10-5×x2-0.0246x+103.008
yC＝-8.27719×10-9×x3+3.6009×10-5×x2-0.04805x+101.753
其中，x为电池循环次数，yA为第一电池类型的电池容量保持率，yB为第二电池类型的电池容量保持率，yC为第三电池类型的电池容量保持率。
对于本方案涉及的电池容量保持率与电池循环次数，可以为在执行本方案前，通过对不同电池类型的电池实际容量和电池额定容量数据进行统计汇总，分别获得每个电池类型对应的经验值。具体地，第一电池类型的电池容量保持率和电池循环次数的关系如图4所示，第二电池类型的电池容量保持率和电池循环次数的关系如图5所示，第三电池类型的电池容量保持率和电池循环次数的关系如图6所示。
需要说明的是，在本发明实施例中提及的第一电池类型、第二电池类型和第三电池类型是列举的电池类型，对于电池类型可以基于不同厂商的电池进行测试分类，本发明实施例中对于电池类型的分类方式不做限制。不同的分类方式拟合出来的电池容量保持率和电池循环次数的关系会有所不同。
可选地，在实际应用中，为了选择碳排量小的方式进行回收，需要获得电池生命周期中两个重要阶段的碳排放量，其中一个是电池充放电过程中电力损耗碳排放量。第一电池类型和第二电池类型的两种电池的电力损耗碳排放量的公式为：



其中，GA再生利用为第一电池类型进行再生利用所需的电力损耗碳排放量，GA梯次利用为第一电池类型进行梯次利用所需的电力损耗碳排放量，GB再生利用为第二电池类型进行再生利用所需的电力损耗碳排放量，GB梯次利用为第二电池类型进行梯次利用所需的电力损耗碳排放量，mA为第一电池类型的电池额定容量，mB为第二电池类型的电池额定容量，EF为电力排放因子，z为电池充放电效率，yA为第一电池类型的电池容量保持率，yB为第二电池类型的电池容量保持率。
可选地，在实际应用中，电池回收工艺碳排放量可以直接获取，也可以通过回收工艺中每个处理阶段的碳排放量获得，公式为：
E＝∑Mi×EFi
其中，E为回收工艺碳排放量，Mi为回收工艺阶段使用原辅料、能源的质量或能量，EFi为回收工艺阶段使用原辅料、能源的质量或能量的排放因子。
对于电池的回收工艺而言，电池采用不用的回收方式时，回收工艺所包含的处理阶段则不同。场景的电池回收方式是再生利用和梯次利用。
其中，梯次利用属于轻度报废，电池本身并没有报废，只是不能用于新能源汽车，经过工艺处理后可以用于其他领域。电池梯次利用的回收工艺包括但不限于运输、拆解、性能测试、BMS系统、组装和包装运输。
较之梯次利用而言，再生利用属于重度报废，需要通过化学方式提炼电池中的稀缺资源达到电池再造的目的。电池再生利用的回收工艺包括但不限于包装、运输、物理放电、化学放电、拆解、破碎、热解、分选、酸浸、萃取、沉淀、混料、煅烧、除杂和包装。
为了更清楚地说明本申请实施例提供的电池的回收方式确定方法，下面分别使用第一电池类型和第二电池类型的两款电池进行示例性说明。
在本示例中，假设本次需要确定回收方式的电池类型为第一电池类型，电池额定容量为75kWh，电池进行再生利用时回收工艺碳排放量为47.01kgCO2e/kWh，电池进行梯次利用时回收工艺碳排放量为16.21kgCO2e/kWh，再生利用的电池循环寿命为2010，梯次利用的电池循环寿命为160，电池的容量保持率在48％左右，从图4可知，电池循环次数约为2370。由此可得，
z＝1.0944x-0.0245
y＝-1.3577×10-8×x3+3.3137×10-5×x2-0.0246x+103.008

经计算，电池进行再生利用的碳排放量为1.47kgCO2e/圈，电池进行梯次利用的碳排放量为2.94kgCO2e/圈，因此梯次利用单次充放电的碳排放量高于再生利用单次充放电的碳排放量，因此建议该电池进行再生利用回收。
在本示例中，假设本次需要确定回收方式的电池类型为第二电池类型，电池额定容量为50kWh，电池进行再生利用时回收工艺碳排放量为49.21kgCO2e/kWh，电池进行梯次利用时回收工艺碳排放量为16.86kgCO2e/kWh，再生利用的电池循环寿命为2100，梯次利用的电池循环寿命为490，电池的容量保持率在61％左右，从图5可知，电池循环次数约为2790。由此可得，
z＝1.0944x-0.0245
y再生利用＝-0.01x+100.61 1≤x≤2100
y梯次利用＝-0.00615x+229 2100≤x≤3240

经计算，电池进行再生利用的碳排放量为1.48kgCO2e/圈，电池进行梯次利用的碳排放量为2.94kgCO2e/圈，因此梯次利用单次充放电的碳排放量高于再生利用单次充放电的碳排放量，因此建议该电池进行再生利用回收。

计算模块202，用于根据电池类型、电池循环次数、电池充放电效率、电池容量保持率、电力排放因子、电池额定容量，得到电力损耗碳排放量，电力损耗碳排放量为电池充放电过程中损耗电力产生的碳排放量；根据电力损耗碳排放量、回收工艺碳排放量和电池循环寿命，分别得到再生利用和梯次利用的电池单次充放电的碳排放量。
决策模块203，用于比较再生利用和梯次利用的电池单次充放电的碳排放量，选择碳排放量 小的方式作为待确定电池的目标回收方式。
可选地，获取模块201还用于初始化电池预设参数；分别预置每种电池类型对应的电池循环次数、电池循环寿命、电池额定容量、电池类型、回收工艺碳排放量、电力排放因子、电池容量保持率和电池充放电效率；其中，电池容量保持率和电池充放电效率通过多种电池类型的采样数据拟合确定。
