S104:根据所述当前剩余电量以及所述目标电量确定充电总时长。
S105:确定当前时刻之后的下一用车起始时刻。
S106:根据所述充电总时长以及所述下一用车起始时刻确定所述充电起始时刻。
S107:在所述充电起始时刻到来时,控制为所述车辆充电。
本申请实施例提供的充电控制方法,能够根据用户的用车需求确定车辆的目标电量,使得车辆的电池尽量处于较低电态,并根据所述目标电量和车辆的当前剩余电量确定充电总时长,以及根据所述充电总时长和下一用车起始时刻确定合适的充电起始时刻,并控制车辆在所述充电起始时刻开始充电,可避免电池长时间处于高电态,从而延长电池寿命。
其中,所述目标电量可表示所述车辆在充电结束时的电量状态。
其中,所述当前剩余电量、所述预估需求电量及所述目标电量均为总电量的百分比值,比如20%,70%,80%等等。
在一些实施例中,所述预估需求电量可根据用户的用车习惯确定,具体的,所述车辆存储有用户在第二预设时长内的使用习惯数据,所述使用习惯数据包括在所述第二预设时长内,所述车辆每次充电的充电时刻以及每次用车的用车里程,所述每次充电的充电时刻为该次充电的充电起始时刻。
请参阅图2,图2为图1中步骤S101的子流程图。如图2所示,在一些实施例中,所述确定所述车辆的预估需求电量,包括:
S1011:获取所述车辆在满电状态下的可行驶里程N。
S1012:根据所述使用习惯数据确定当前时刻之后的下一充电时刻以及当前时刻至所述下一充电时刻的时间段内的用车总里程M,其中,所述用车总里程M为当前时刻至所述下一充电时刻的时间段内的所有用车里程之和。
S1013:根据所述用车总里程M以及所述可行驶里程N确定预估需求电量SOCrq,其中,所述预估需求电量SOCrq=M/N*100%。
其中,所述第二预设时长可为1天、1周、1个月、3个月等,例如,所述第二预设时长可为1周,所述使用习惯数据包括周一至周日每天每次充电的充电时刻、每天每次用车的用
车里程以及每天每次用车的用车起始时刻,所述每次充电的充电时刻为该次充电的充电起始时刻。其中,所述第二预设时长越长,所述使用习惯数据越具有共性。
可以理解的是,所述使用习惯数据表示的是第二预设时长内用户对车辆的充电和用车的习惯,而大部分用户对车辆的充电和用车均是可以预测和具有通用性,因此,在第二预设时长内的使用习惯数据代表过去用户对车辆的充电和用车习惯,若非特殊情况,所述使用习惯数据可用于预测用户未来的充电和用车习惯。
其中,所述满电指的是所述车辆的电池的最大可用电量,所述最大可用电量可根据电池的可存储的最大电量与预设固定电量确定,所述最大可用电量为所述可存储的最大电量与所述预设固定电量之差,例如,所述可存储的最大电量为100%,所述预设固定电量为10%,则所述最大可用电量为90%。其中,所述预设固定电量的值可根据实际需求设定为其它值,所述预设固定电量为不可用电量,即,在所述电池的电量消耗至等于所述预设固定电量时,所述电池不再为所述车辆提供电力。通过设置所述预设固定电量,可防止所述电池因电量耗尽而过放电,从而可延长电池使用寿命。
在其它实施例中,所述满电可等于所述可存储的最大电量,即为100%。
可以理解的是,根据所述使用习惯数据中的所述第二预设时长内每次充电的充电时刻可确定当前时刻之后的下一充电时刻;而根据所述使用习惯数据中的所述第二预设时长内每次用车的用车里程可确定当前时刻至所述下一充电时刻的时间段内的用车次数以及每次用车的用车里程,进而可确定当前时刻至所述下一充电时刻的时间段内的用车总里程M,例如,根据所述第二预设时长内每次用车的用车里程确定当前时刻至所述下一充电时刻的时间段内,共有n次用车,第一次用车的用车里程为M1,第二次用车的用车里程为M2,…,第n次用车的用车里程为Mn,则所述用车总里程M=M1+M2+…+Mn。
本实施例中,通过获取用户的使用习惯数据确定用户的用车需求并根据用车需求确定所述预估需求电量,在满足用户的用车需求的同时,也能避免所述车辆充电至满电而使得电池处于较高电态,从而可延长电池使用寿命。并且,通过获取用户的所述使用习惯数据确定用户在当前时刻至所述下一充电时刻的时间段内的用车总里程并根据所述用车总里程确定所述预估需求电量,能够智能、快速、简便地计算所述车辆的耗电,而得到所述预估需求电量。并且,由于在车辆的使用中,耗电与行驶路程最相关,因此通过所述用车总里程确定所述预估需求电量考虑到了用户对所述车辆的实际使用的过程。
在其它一些实施例中,所述预估需求电量可由用户根据实际用车需求预先设置,例如,用户根据实际用车需求在车辆的多媒体界面输入预估需求电量为70%。
在其它一些实施例中,所述预估需求电量还可为100%。
请参阅图3,图3为图1中步骤S103的子流程图。如图3所示,在一些实施例中,所述根据所述预估需求电量及所述当前剩余电量判断是否需要进行充电,并在确定需要进行充电时,确定所述目标电量,包括:
S1031:在确定所述预估需求电量大于所述当前剩余电量时,确定需要进行充电,并根据所述预估需求电量与所述车辆的预防过放电量阈值的关系确定所述车辆的目标电量。
S1032:在确定所述预估需求电量小于或等于所述当前剩余电量时,根据所述当前剩余电量与所述车辆的预防过放电量阈值的关系确定是否需要进行充电,以及确定所述车辆的目标电量,其中,所述预防过放电量阈值为所述车辆的电池发生过放的电量最大值。
请参阅图4,图4为图3中步骤S1031的子流程图。如图4所示,在一些实施例中,所
述在确定所述预估需求电量大于所述当前剩余电量,确定需要进行充电,并根据所述预估需求电量与所述车辆的预防过放电量阈值的关系确定所述车辆的目标电量,包括:
S10311:在确定所述预估需求电量大于所述当前剩余电量,且所述预估需求电量与预设电量之和大于或等于预防过放电量阈值时,确定需要进行充电且确定所述目标电量等于所述预估需求电量与所述预设电量之和。
S10312:在确定所述预估需求电量大于所述当前剩余电量,且所述预估需求电量与预设电量之和小于预防过放电量阈值时,确定需要进行充电且确定所述目标电量等于所述预防过放电量阈值。
其中,所述预设电量可由用户根据需求设定。在一些实施例中,所述预设电量可为0至15%中的一个值,例如,0,10%,15%。
其中,所述预防过放电量阈值可由用户根据需求设定。所述预防过放电量阈值是指所述车辆的电池发生过放的电量最大值。在一些实施例中,所述预防过放电量阈值可为20%至40%中的一个值,例如,25%、30%。
其中,通过比较所述预估需求电量与所述当前剩余电量的大小,确定所述车辆需要充电。在确定所述车辆需要充电时,比较所述预估需求电量与所述预设电量之和与所述预防过放电量阈值的大小,在确定所述预估需求电量与所述预设电量之和大于或等于所述预防过放电量阈值时,确定所述车辆需要充电至的目标电量等于所述预估需求电量与所述预设电量之和;在确定所述预估需求电量与所述预设电量之和小于所述预防过放电量阈值时,确定所述车辆需要充电至的目标电量等于所述预防过放电量阈值。
例如,预估需求电量为60%,当前剩余电量为20%,预设电量为10%,预防过放电量阈值为30%,则确定所述车辆需要充电,且所述目标电量为60%+10%=70%;又例如,预估需求电量为15%,当前剩余电量为10%,预设电量为10%,预防过放电量阈值为30%,则确定所述车辆需要充电,且所述目标电量为30%。
其中,在所述预设电量大于0,且所述车辆需要充电时,通过控制将所述车辆充电至等于所述预估需求电量与所述预设电量之和的所述目标电量,使得所述车辆的目标电量在满足用户的用车需求的同时,所述车辆还储有所述预设电量作为备用,可防止用户临时增加用车里程,导致所述车辆因电量不足而无法使用。此外,所述预设电量还可作为充入所述车辆的电量的校正补偿量。具体的,由于充电过程中充入所述车辆的电池的电量可能与设定值存在偏差,通过控制将所述车辆充电至所述预估需求电量与所述预设电量之和的目标电量,能够补偿充电过程中充入电量的偏差,使得所述目标电量至少大于所述预估需求电量,而满足用户的用车需求。
其中,通过控制将所述车辆的目标电量大于或等于所述预防过放电量阈值,可使得所述车辆在停滞不用时,具备充足电量用于电池的自放电过程,从而防止电池过放而缩短电池寿命。
请参阅图5,图5为图3中步骤S1032的子流程图。如图5所示,在一些实施例中,所述在确定所述预估需求电量小于或等于所述当前剩余电量时,根据所述当前剩余电量与所述车辆的预防过放电量阈值的关系确定是否需要进行充电,以及确定所述车辆的目标电量,其中,所述预防过放电量阈值为所述车辆的电池发生过放的电量最大值,包括:
S10321:在确定所述预估需求电量小于或等于所述当前剩余电量,且所述当前剩余电量小于所述预防过放电量阈值时,确定需要进行充电且确定所述目标电量等于所述预防过放电
量阈值。
S10322:在确定所述预估需求电量小于或等于所述当前剩余电量,且所述当前剩余电量大于或等于所述预防过放电量阈值时,确定无需充电。
其中,在确定所述预估需求电量小于或等于所述当前剩余电量时,比较所述当前剩余电量与所述预防过放电量阈值的大小,在确定所述当前剩余电量小于所述预防过放电量阈值时,确定所述车辆需要充电,并且确定所述车辆需要充电至的目标电量等于所述预防过放电量阈值。例如,预估需求电量为20%,当前剩余电量为25%,预防过放电量阈值为30%,则确定所述车辆需要充电,且所述目标电量为30%。
其中,在确定所述预估需求电量小于或等于所述当前剩余电量时,比较所述当前剩余电量与所述预防过放电量阈值的大小,在确定所述当前剩余电量大于或等于所述预防过放电量阈值时,确定所述车辆无需充电。例如,预估需求电量为20%,当前剩余电量为50%,预防过放电量阈值为30%,则确定所述车辆无需充电。
其中,在所述车辆需要充电时,通过控制将所述车辆充电至大于或等于所述预防过放电量阈值的所述目标电量,使得所述车辆在停滞不用时,具备充足电量用于电池的自放电过程,从而防止电池过放而缩短电池寿命。
本申请实施例中,根据所述预估需求电量、当前剩余电量、预设电量及预防过放电量阈值,确定所述车辆是否需要充电并在所述车辆需要充电时确定所述目标电量,不仅使得所述车辆的目标电量满足用户在所述下一充电时刻前的用车需求,还可防止充入过多电量或者在所述车辆无需充电时充入电量使得所述车辆处于较高电态,而延长电池寿命。并且,在所述当前剩余电量大于或等于所述预估需求电量且大于或等于所述预防过放电量阈值时,确定所述车辆无需充电,即所述当前剩余电量能够满足用户的用车需求,从而能够避免所述车辆的不必要充电,导致电池处于高电态而缩短寿命。
在其它一些实施例中,还可在所述预估需求电量小于或等于所述当前剩余电量时,确定所述车辆不需要充电。所述车辆的当前剩余电量已经能够满足用户的用车需求,因此可不对所述车辆进行充电。
在一些实施例中,所述根据所述当前剩余电量以及所述目标电量确定充电总时长,包括:根据所述当前剩余电量以及所述目标电量确定目标充电电量;确定目标充电电流;以及根据所述目标充电电量以及目标充电电流确定充电总时长。
本实施例中,通过所述目标充电电量以及目标充电电流可确定所述充电总时长,进而可确定所述充电起始时刻。
请参阅图6,图6为本申请实施例提供的确定充电总时长的流程图。在一些实施例中,所述车辆的电池对应多个连续的电量区间。如图6所示,在一些实施例中,所述根据所述当前剩余电量以及所述目标电量确定目标充电电量,确定目标充电电流,根据所述目标充电电量以及目标充电电流确定充电总时长,包括:
S1041:确定当前剩余电量所在的第一电量区间以及所述目标电量所在的第二电量区间。
S1042:确定所述第一电量区间的第一目标充电电量、所述第二电量区间的第二目标充电电量以及位于所述第一电量区间与所述第二电量区间之间的至少一个中间电量区间的至少一个中间目标充电电量。
S1043:确定所述第一电量区间的第一目标充电电流、所述第二电量区间的第二目标充电电流以及位于所述第一电量区间与所述第二电量区间之间的至少一个中间电量区间的至少一
个中间目标充电电流。
S1044:将所述第一目标充电电量除以所述第一目标充电电流得到第一充电时长。
S1045:将所述第二目标充电电量除以所述第二目标充电电流得到第二充电时长。
S1046:将所述至少一个中间目标充电电量分别除以所述至少一个中间目标充电电流得到至少一个中间充电时长,其中,所述至少一个中间目标充电电量与所述至少一个中间目标充电电流一一对应。
S1047:将第一充电时长、第二充电时长与所述至少一个中间充电时长相加而得到所述充电总时长。
其中,可以预设间隔电量将所述车辆的电池的电量状态(SOC,State of charge)从0至100%划分为多个连续的电量区间,例如,以相同的预设间隔电量10%,将电池的SOC等间隔划分为[0%,10%),[10%,20%),[20%,30%),[30%,40%),[40%,50%),[50%,60%),[60%,70%),[70%,80%),[80%,90%),[90%,100%]等10个连续的电量区间。显然,所述预设间隔电量还可为其它值。并且所述预设间隔电量还可为多个且互不相同,例如,预设间隔电量为10%和20%,分别以10%、20%的间隔电量将电池的SOC划分为[0%,10%),[10%,20%),[20%,30%),[30%,40%),[40%,60%),[60%,80%),[80%,100%]等7个连续的电量区间。
其中,所述第一电量区间包含所述当前剩余电量,所述第二电量区间包含所述目标电量,所述中间电量区间为介于所述第一电量区间和所述第二电量区间之间的电量区间,例如,所述多个连续的电量区间分别为[0%,10%),[10%,20%),[20%,30%),[30%,40%),[40%,50%),[50%,60%),[60%,70%),[70%,80%),[80%,90%),[90%,100%],当前剩余电量为23%,目标电量为75%,则所述第一电量区间为[20%,30%),所述第二电量区间为[70%,80%),所述至少一个中间电量区间的数量为4个,4个中间电量区间分别为[30%,40%),[40%,50%),[50%,60%),[60%,70%)。在一些实施例中,所述第一电量区间和所述第二电量区间为相邻的两个电量区间,例如,当前剩余电量为23%,目标电量为35%,则所述第一电量区间为[20%,30%),所述第二电量区间为[30%,40%),此时,则无需确定所述中间电量区间。
其中,所述中间电量区间的数量为多个时,确定至少一个中间电量区间的至少一个中间目标充电电量,包括:确定每一电量区间的中间目标充电电量,而得到所有中间电量区间的中间目标充电电量。确定至少一个中间电量区间的至少一个中间目标充电电流,包括:确定每一电量区间的中间目标充电电流,而得到所有中间电量区间的中间目标充电电流。所述将所述至少一个中间目标充电电量除以对应的中间目标充电电流得到至少一个中间充电时长,包括:将每一中间电量区间的中间目标充电电量除以该中间电量区间的中间目标充电电流得到该中间电量区间的中间充电时长,而得到所有中间电量区间的中间充电时长。所述将第一充电时长、第二充电时长与所述至少一个中间充电时长相加而得到所述充电总时长,包括:将第一充电时长、第二充电时长及所有中间电量区间的中间充电时长相加而得到所述充电总时长。
例如,所述中间电量区间的数量为3个时,分别为[20%,30%),[30%,40%),[40%,50%),确定中间电量区间[20%,30%)的中间目标充电电量Ca和中间目标充电电流Ia、中间电量区间[30%,40%)的中间目标充电电量Cb和中间目标充电电流Ib、以及中间电量区间[40%,50%)的中间目标充电电量Cc和中间目标充电电流Ic。进一步的,得到中间电量区间[20%,30%)的中间充电时长ta=Ca/Ia,中间电量区间[30%,40%)的中间充电时长tb=Cb/Ib,以及中间电量区间[40%,50%)的中间充电时长tc=Cc/Ic,此时,所述充电总时长等于第一充电时长、第二充
电时长、ta、tb及tc之和。
本申请实施例中,通过根据所述当前剩余电量、所述目标电量确定所述第一电量区间、第二电量区间和至少一个中间电量区间,并根据不同电量区间确定对应的目标充电电流,使得在电池处于不同的电量状态时,根据电池的电量状态输入对应的目标充电电流,可避免因充电电流过大对电池的性能造成影响,并且可避免因充电电流过小导致充电时间过长而降低充电效率。
