具体实施方式
需要说明的是,在不冲突的情况下,本公开中的实施方式及实施方式中的特征可以相互组合。
本公开的下述实施例将针对燃料电池车辆来进行详细描述,其中,所述燃料电池车辆包括动力电池和燃料电池,下面将针对所述动力电池来进行详细的描述,另外,为了描述的方便,下面将所述动力电池称之为电池来进行描述。

环境温度范围 功率限制 功率上升速率
≥60℃ ≤120kW 45kW/s
20~60℃ ≤60kW 35kW/s
5~20℃ ≤40kW 20kW/s
≤5℃
在车辆启动时,若电池温度过低,需要对电池进行加热,这样会使得车辆的启动时间变长,并且会浪费电源电量,若所述电池长期在低温环境下启动,会造成电池的寿命减短。为了避免出现上述的问题,本公开特别通过下述多个附图来进行进一步的说明。
图1是车辆电池的充电保温方法的流程图,如图1所示,所述车辆电池的充电保温方法包括:
S101,获取在车辆的电池已完成充电后的预期用车时间及其对应的用于给所述电池进行加热的充电加热功能的预期开启时间,其中所述预期开启时间在所述预期用车时间之前;以及
S102,在实时时间达到所述预期开启时间时,根据所述电池的当前温度和所述预期用车时间,控制所述车辆开启所述充电加热功能,以使得所述电池的当前温度达到安全温度上限阈值或实时时间达到所述预期用车时间。
其中,所述预期用车时间为车辆此次充电完成后的预期使用车辆的时间,例如,预计此次预期使用时间为9点,所述充电加热功能主要用于对电池进行加热,并且其预期开启时间可以为预期使用时间的前1小时,在本实施例中,其可以根据用户需求自行设定,当然,本公开为了使得所述预期用车时间以及预期开启时间与实际情况更加匹配,将通过下述的方式来获取预期用车时间以及预期开启时间。
图2是获取预期用车时间以及预期开启时间的方法流程图,如图2所示,所述获取在车辆的电池已完成充电后的预期用车时间及其对应的用于给所述电池加热的充电加热功能的预期开启时间包括:
S201,根据用户的历史用车数据,确定当前用车情况所对应的所述预期用车时间,其中所述历史用车数据包括以下用车情况中的一者或多者与历史用车时间的对应关系:驾驶习惯数据、驾驶需求数据、用车区域数据和用车环境数据。
其中,所述历史用车数据实际即为用户A使用所述车辆的*** 台,统计用户使用所述车辆时的用车***台确定当前用车情况所对应的预期用车时间。
S202,根据当前环境温度和所述预期用车时间,确定所述充电加热功能的预期开启时间。
其中,所述当前环境温度为充电时的环境温度,例如-5℃,所述预期用车时间为S201所确定的时间,所述充电加热功能的预期开启时间被配置为关联于将所述电池从当前环境温度加热至安全温度上限阈值以上的持续时间。例如,将电池从-5℃加热至20℃的时间为2小时,那么在预期用车时间为9点时,所述充电加热功能的预期开启时间为7点,使得在用户9点使用车辆时车辆的电池温度达到20℃,用户如果在预期用车时间使用车辆,则启动车辆后无需继续对电池进行加热即可让电池达到可高效率使用的状态。
其中,所述充电加热功能主要为对所述电池进行加热,其中加热的开启时间和持续时间根据车辆的实际情况来确定,其中,具体的充电加热功能的加热方式如下所述。
进一步优选地,在S102中,所述根据所述电池的当前温度和所述预期用车时间,控制所述车辆开启所述充电加热功能包括:检测所述电池的当前温度是否小于所述安全温度下限阈值;以及根据所述检测的结果和所述预期用车时间,控制所述车辆开启所述充电加热功能。
其中,所述安全温度下限阈值可以是5℃,检测所述电池的当前温度可以采用车辆原有的电池温度传感器,在所述检测的结果示出所述电池的当前温度小于5℃,且未达到所述预期用车时间时,控制所述车辆的充电加热功能持续开启,一旦达到所述预期用车时间则即使未达到所述20℃也停止对所述电池进行加热,避免用户使用车辆时车辆还在自动加热,此时,只需要根据用户的实际需求来进行加热的设定。
