具体实施方式
需要说明的是，在不冲突的情况下，本发明中的实施方式及实施方式中的特征可以相互组合。
本发明是针对整车充电完成后的燃料电池车辆的电池的加热保温。其中，现有技术中虽然公开了对电池的加热及保温，但是，现有技术并未在整车充电完成后进行上述操作，并且，现有技术是利用的电能为车辆的电池的电能，这样会造成车辆的续航里程缩短。下面将结合附图对本发明实施例的技术方案进行详细的说明。
图1是本发明实施例的一种车辆的电池保温方法的流程示意图。如图1所示，所述车辆的电池保温方法包括：
S101，响应于整车充电完成，检测所述车辆的电池的当前温度是否小 于预设定的所述电池的温度阈值，其中所述温度阈值被配置为所述电池能够维持正常性能的最低温度值；
S102，在检测结果为是时，控制所述车辆从外部充电设备获取电能以对所述电池进行加热，使得所述电池被加热至所述温度阈值以上，完成所述电池的保温。
在本实施例中，所述外部充电设备可以车载充电机，其电能来自给车辆进行充电的电网，对所述电池进行加热的部件可以是PTC加热器，其中PTC全称为Positive Temperature Coefficient，即正的温度系数，泛指正温度系数很大的半导体材料或元器件，例如，其可以是PTC热敏电阻。
具体地，在驾驶员对车辆进行外插充电时，车辆会提醒驾驶员是否执行电池保温的功能，在驾驶员选择执行该功能时，使得车辆的整车充电完成后，诊断所述电池的当前温度，下面将以动力电池和燃料电池为例，详细说明诊断所述电池的当前温度的步骤。需要说明的是，在涉及电池控制时，对动力电池的控制可以泛指对电池管理***(BMS，Battery Management System)的控制，对燃料电池的控制可以表述为燃料电池控制器(FCU，Fuel Cell Unit)的控制，故而在本发明实施例中，动力电池与BMS可以等同理解，且燃料电池与FCU也可等同理解。
由上述描述可知，动力电池和燃料电池由于种类的不同，其两者对应的温度阈值也不同，在本实施例中，所述动力电池的温度阈值为20℃，所述燃料电池的温度阈值为5℃。对于BMS，当检测所述动力电池的当前温度小于20℃时，整车控制器会请求所述车载充电机从电网中获取电能以对所述BMS进行加热，在所述BMS被加热到大于等于20℃时，停止加热，完成所述BMS的保温；对于FCU，当检测所述FCU的当前温度小于5℃时，整车控制器会请求所述车载充电机从电网中获取电能以对所述FCU进行加热，在所述FCU被加热到大于等于5℃时，停止加热，完成所述FCU 的保温。
进一步优选地，在所述检测结果为否或者所述电池已被加热至所述温度阈值以上时，控制所述车辆进入睡眠模式。
其中，所述睡眠模式被配置为所述车辆的用电设备处于下电休眠状态，即所述车辆的用电设备耗能极低或者不耗能，极大降低了耗电。
具体地，对于具有BMS和FCU的混动车辆进行诊断时，需要满足下述条件一和条件二才能进入睡眠模式：
条件一：检测到的所述BMS的当前温度大于或等于20℃；或者所述BMS被加热到大于等于20℃；
条件二：检测到的所述FCU的当前温度大于或等于5℃；或者所述FCU被加热到大于等于5℃。
通过上述的方式，可以使得电池处于低温环境下不会被持续加热，尽可能的减少了电能的损耗，避免持续加热造成的电量损失。
进一步优选地，图2是在上述控制所述车辆进入睡眠模式后持续执行的步骤，用于确保车辆在使用之前，电池的保温，且耗电较低。如图2所示，所述车辆的电池保温方法还包括：
重复执行以下步骤S201-S204，直至所述车辆被启动：
S201，在所述车辆进入所述睡眠模式持续预设时间后，控制所述车辆从所述睡眠模式中被唤醒；
S202，继续检测所述车辆的电池的当前温度是否小于所述温度阈值；
S203，在所述继续检测的结果为是时，控制所述车辆从外部充电设备获取能量以对所述电池进行加热，使得所述电池被加热至所述温度阈值以上；
S204，在所述继续检测的结果为否或者所述电池已被加热至所述温度阈值以上时，控制所述车辆继续进入睡眠模式。
首先，在S201中，所述持续时间以30分钟为例，当前，其具体数值可 以根据实际需要进行设定，尽可能保证用户在使用所述车辆的时候，其电池的温度能够离所述温度阈值较近。所述车辆从所述睡眠模式中被唤醒，进而用电设备可以继续工作，执行下述的步骤。
接着，在S202中，继续以BMS和FCU为例，继续检测所述BMS的当前温度是否小于20℃以及所述FCU的当前温度是否小于5℃。
接着，在S203中，在所述继续检测结果为是即所述BMS的当前温度小于20℃和/或所述FCU的当前温度小于5℃，若所述BMS的当前温度小于20℃，则对所述BMS进行加热，若所述FCU的当前温度小于5℃则对所述FCU进行加热，使得BMS和所述FCU均被加热至所述温度阈值以上。
最后，在S204中，在所述继续检测的结果显示满足下述条件三或条件四的情况下，控制车辆继续进入睡眠模式。条件三，所述BMS的当前温度大于或等于20℃且所述FCU的当前温度大于或等于5℃；条件四，所述BMS和所述FCU均被加热至所述温度阈值以上。
通过上述的方式，可以在指定时间控制所述车辆进入睡眠模式，且所述车辆的唤醒时机是以上次进入睡眠模式的时间为起始时间进行计算的，例如，上次进入睡眠模式的时间是12:00，那么车辆的唤醒时间以30分钟为例，就应该是12:30。在进入睡眠模式前车辆一定是满足进入睡眠模式条件的。若采用固定时间间隔对车辆进行唤醒，则可能在外界环境温度较低时车辆对电池的加热时间间隔过短，车辆反复进入睡眠状态和被唤醒，切换的过程造成能源的浪费。采用上述实施例的方式，可以使得车辆睡眠、唤醒时间间隔固定，与加热时间无关，尽可能的减少所述车辆在对电池进行加热的过程切换睡眠状态造成的电能损耗。
进一步优选地，所述电池保温方法还包括：响应于用户针对用于激活充电保温功能的按键的点击操作，控制所述车辆激活所述充电保温功能，以执行所述检测所述车辆的电池的当前温度是否小于预设定的所述电池的温度 阈值的步骤。
其中，用户或驾驶员在将车载充电机接到电网中时，车辆的车载主机或与车辆连接的手机终端会接收到示出是否激活充电保温功能的按键，用户或驾驶员可以通过点击所述按键，完成该功能的选择操作，确定是否激活所述充电保温功能，在确定激活的情况下，执行上述图1和图2中的步骤。
通过上述的方式，可以使得用户可以手动操作来确定是否激活所述充电保温功能，使其可以满足用户的需求，选择是否执行车辆的电池充电保温，提高用户的操作体验。
图3是本发明的一种车辆的电池保温方法的流程图，其包含了BMS(泛指动力电池)和FCU(泛指燃料电池)两种电池。如图3所示，所述车辆的电池保温方法包括：
S301，将车载充电机连入电网进行充电；
S302，用户设置充电保温功能可激活；
S303，充电完成；
S304，整车控制器激活充电保温功能；
S305，检测BMS的温度是否小于温度阈值20℃；
S306，在所述BMS小于20℃时，通过电网利用车载充电器对BMS即动力电池进行加热；
S307，判断加热后的所述BMS温度是否小于20℃，若加热后的所述BMS温度小于20℃，返回步骤S306；
S308，检测FCU的温度是否小于温度阈值5℃；
S309，在所述FCU小于5℃时，通过电网利用车载充电器对FCU即燃料电池进行加热；
S310，判断加热后的所述FCU温度是否小于5℃，若加热后的所述 FCU温度小于5℃，返回步骤S309；
S311，在所述S308和S310的结果示出无需对BMS和FCU进行加热时，控制车辆进入睡眠状态。
其中，所述车辆的电池保温方法与图1、图2所示方法相对于现有技术所具有的优势相同，在此不再赘述。
