需要说明的是,本申请实施例以考虑环境因素对电池的影响,具体的可以是考虑温度对电池的影响为例来进行说明。
图1示出了本申请实施例提供的一种电池续航能力确定方法的流程示意图,如图1所示,该电池续航能力确定方法可以包括如下步骤110-步骤130。

步骤12021、获取满充时段内单位时间的电参数变化量中的电参数变化量最高位置处的第一电池容量。
步骤12022、基于电参数变化量最高位置和满充时刻位置之间的电参数变化量,得到电参数变化量最高位置和满充时刻位置之间的第二电池容量。
步骤12023、基于第一电池容量和第二电池容量,得到电池在预设温度下的可发挥容量。
其中,电参数变化量最高位置处可以是电参数变化量最大的位置处,即为图3中的A点位置。
第一电池容量可以是电参数变化量最高位置处的电池容量。即图3中的A点位置的电池容量,该第一电池容量用于表征电池充电到A位置时所充的电量。
在本申请的一些实施例中,第一电池容量可以是预先基于电芯实验得到。即可预先通过电芯实验得到电池在充电到电参数变化量最高位置处的电量为多少。
在本申请的一些实施例中,通过电芯实验可得到电池在充电到电参数变化量最高位置处的电量为满充电量的60%-70%。

其中,实际可用容量可以是电池在当前温度信息下,真实可以用的容量。

步骤140、获取在当前温度信息下,车辆行驶目标行程所需的目标电池容量。
步骤150、在实际可用容量小于目标电池容量的情况下,确定车辆在目标行程过程中发生抛锚。
其中,目标行程可以是车辆所要行驶的行程。例如车辆需要从地点G行驶到地点H,则从地点G到地点H所走的行程即为目标行程。
目标电池容量可以是在当前温度信息下,车辆行驶目标行程所需的电量。即车辆从地点G到地点H所需要消耗的电量。
在一个示例中,参考图9,图9中纵坐标为电量,横坐标为时间,图9中曲线91为当前温度信息下电池的实际可用容量,曲线92为在当前温度信息下,车辆行驶目标行程所需的目标电池容量,图9中在方框93所对应的时间段内温度下降,电池的实际可用容量降低,无法满足车辆行驶目标行程所 需的目标电池容量,出现抛锚。

在本申请的实施例中,可基于输出的抛锚预警信息,以使售后人员基于该抛锚预警信息,对车辆进行维修处理,以确保车辆可行驶完成目标行程,提升用户体验。
需要说明的是,上述实施例是以温度对电池的影响来进行说明的,并非是仅温度可影响电池容量,上述方案还可以应用于其他因素对电池容量的影响,例如可以是电池的使用年限、电池的出厂厂商等。
在外界影响因素为温度时,电池在当前温度信息下的实际可用容量与温度的关系可以是如下所示:实际可用容量=g(电池温度,环境温度,……)。
对应的,车辆行驶目标行程所需的目标电池容量与当前温度信息的对应关系可以如下:目标电池容量=f(环境温度,行车时长,……)。
上述两个应关系的具体实现可以灵活调整,工况参数越多(这里的工况参数可以根据需求自行设置,这里不做限定),对应关系越准确。
