本申请涉及一种电动车。
背景技术
电动车作为一种绿色环保的交通工具,越来越被广泛使用。电动车均自带有电池,且被配置在电动车的内部。当电池显示电量不足需要充电时,将充电器直接插入到电动车上的充电接口,以对其内部的电池进行充电。
现有技术中,电动车通常采用一组电池供电,续航时间短。其次,在该电池没电或电量不足时,电动车内置的电池不方便进行更换,只能花较长的时间充电,待充电一定时间后才能再次使用电动车。另外,目前电动车中配置的电池包都是专门为电动车设计的,电动车不能连接其他工具用的电池包,导致电动车的可用的能源类型低。

为了能够增加现有电动车的续航里程,本申请提供了一种能够方便用户长时间使用的电动车。下面将结合图1至图8对本申请实施例的电动车进行解释和说明。需要说明的是,为了便于说明,在本申请的实施例中,相同的附图标记表示相同的部件。而为了简洁,在不同的实施例中,省略对相同部件的详细说明,且相同部件的说明可互相参照和引用。
电动车通常包括车体;设置在所述车体上用于驱动车体前进的驱动机构5,所述车体设置第一供电装置100,所述第一供电装置100包括第一电池包模组101,所述第一电池包模组101与所述驱动机构5电性连接,能向驱动机构5供电。
在本说明书中,所述电动车还包括:第二供电装置200,第二供电装置200设置在所述车体上,包括可拆卸的第二电池包模组201,所述第二电池包模组201与所述驱动机构5电性连接,能向所述驱动机构5供电,所述第二电池包模组201能够通用不同直流设备。第二电池包模组201可拆卸的安装于车体上,从而能够在不影响用户正常使用的情况下,在电动车合适的位置上安装第二供电装置200。当第二电池包模组201的电量用完后,可以随时将第二电池包模组201从车体上拆卸、取下,无需拆除电动车上的其他部件。将第二电池包模组201取出后,更换为电量充足的电池包再加装在车体上,电动车可以立即使用,避免了充电等待的时间。另外,将该第二电池包模组201从车体上拆卸取下后,可以通过充电器单独对其进行充电,待第二电池包模组201的电量充满后,再安装至车体上。
进一步的,该第二供电装置200可以包括:设置在车体上的盒体1,以及设置在所述盒体1中的第二电池包模组201,所述第二电池包模组201可拆卸的安装于所述盒体1中。盒体1可以固定安装在车体上,也可以以方便拆卸的方式安装在车体上。所述第二电池包模组202安装在所述盒体1中后,第一电池包模组101和第二电池包模组201能通过控制电路并联连接,从而第一电池包模组101和第二电池包模组201能够单独供电,提高了电动车的使用时间和续航里程。
如图1、图2和图4所示,所述第一供电装置100可以设置在车体的内。在一个具体的实施方式中,所述电动车具体为滑板车,所述第一供电装置100可以设置在滑板内。在另一个具体的实施方式中,所述电动车具体为电动自行车,如E-BIKE,第一供电装置100可以设置在车架下管50中。当第一供电装置100设置在车体内时,所述第一电池包模组101不可拆卸的固定设置在车体上。由于第一供电装置100位于车体内部,从而与车体的外部环境相对隔离,因此该第一供电装置100可以无需采用防水部件。第一供电装置100中的第一电池包模组101可以仅包括电池组,能够极大的节省内部空间。在相同的空间下,第一电池包模组101可以容纳更多的电池或电芯,进一步提高电动车的续航能力。在一个优选的实施方式中,所述第一电池包模组101能够存储的电量大于所述第二电池包模组201能够存储的电量。
所述第二供电装置200可以外置于车体上。当第二供电装置200外置于车体上时,加装在车体外表面,第二供电装置200可以与车体的外部环境直接接触,从而便于其拆卸。在本说明书中,所述第一供电装置100和所述第二供电装置200分开安装在所述车体的不同位置。将第一供电装置100和第二供电装置200分开安装在不同的安装位置,有利于整车重量的平衡,不至于重量集中,电动车在行驶过程中更加稳定。

在本说明书中,所述第二供电装置200的盒体1包括:充电接口,所述充电接口用于连接充电器单独为所述第二电池包模组201充电。具体的,如若第二电池包模组201不从盒体1中取出,即可以通过该充电接口连接充电器进行充电。当然,如果车体旁边的电源不方便,可以将盒体1从车体上取出,通过充电接口连接充电器进行充电。又或者将所述第二电池包模组201从盒体1中拆卸取出,所述第二电池包模组201能通过专用的电池包充电器进行充电,待第二电池包模组201的电量充满后,再装入盒体1中,然后安装在车体上。在本实施例中,所述充电器类型不作特别限定,可以采用现有技术中的充电器,充电器类型需要与具体加装在盒体1内部的电池包7类型进行匹配。

在本申请的实施例中,请参见图8所示,当该电动车加装有第二供电装置200后,控制电路将第二电池包模组201和第一电池包模组101并联连接。该控制电路包括主开关9,主开关9能够分别与第一供电装置100和第二供电装置200电性连接。主开关9能根据用户操作在断开状态和闭合状态之间切换,当主开关9为闭合状态时,第一供电装置100中的第一电池包模组101或第二供电装置200中的第二电池包模组201能向驱动机构5供电;当主开关9为断开状态时,第一电池包模组101和第二电池包模组201均停止向驱动机构5供电。所述主开关9可以例如包括电动车上的开关按钮,或者例如电动车上的锁机构,通过用户插入钥匙启动或关闭电动车实现主开关9的闭合状态与断开状态的切换。
在本说明书中,电动车包括采用第一供电装置100为驱动机构5供电的第一供电模式和采用第二供电装置200为驱动机构5供电的第二供电模式,控制电路能够用于在第一供电模式和第二供电模式之间进行切换。
图7示出了本申请实施例中第一供电装置100和第二供电装置200的结构框图,图8示出了本申请实施例中控制电路的示意图。从图7和图8中可以看出,第一电池包模组101和第二电池包模组201并联连接,当第一电池包模组101单独向驱动机构5供电时,电动车采用第一供电模式供电;当第二电池包模组201单独向驱动机构5供电时,电动车采用第二供电模式供电。该控制电路通过切换第一电池包模组101和第二电池包模组201与驱动机构5之间的供电回路,在第一供电模式和第二供电模式之间进行切换。
该控制电路包括用于电源管理装置8,所述电源管理装置8用于管理所述第一电池包模组101和所述第二电池包模组201依次为驱动机构5供电。当第一电池包模组101和第二电池包模组201依次为驱动机构5供电时,可以是第一电池包模组101优先于第二电池包模组201放电,也可以是第二电池包模组201优先于第一电池包模组101放电。该电源管理装置8通过管理第一电池包模组101和所述第二电池包模组201的供电顺序,使电动车在第一供电模式和第二供电模式之间切换。所述电源管理装置8能控制第一电池包模组101和第二电池包模组201依次向驱动机构5供电,即电源管理装置8在第一电池包模组101和第二电池 包模组201其中选择一个优先供电。也就是说,第一电池包模组101和第二电池包模组201在同一时刻仅有一个用于为驱动机构5供电,从而增加了电动车的续航时间和续航里程。
所述电源管理装置8可以包括用于控制第一电池包模组101和第二电池包模组201依次向驱动机构5供电的控制组件,该控制组件可以是单片机、CPU、MPU、FPGA等任何能进行数据处理的数据处理单元,控制组件可以通过数据处理单元结合可执行逻辑指令实现,以执行控制组件对第一电池包模组101和第二电池包模组201的处理过程。控制组件可以包括存储模块,以存储控制组件的配置信息。

所述电源管理装置8还包括参数检测模块,所述参数检测模块用于分别检测所述第一电池包模组101和所述第二电池包模组201的状态参数。电源管理装置8根据参数检测模块获取的所述状态参数控制所述第一开关单元102和所述第二开关单元202的连通或断开,从而能够切换第一电池包模组101和第二电池包模组201向驱动机构5供电。所述状态参数可以是与电池包模组电量有关的参数,可以包括:电量、电压、电流、温度中的其中一个或多个。
在一个具体的实施方式中,当参数检测模块检测第一电池包模组101和第二电池包模组201的电量时,可以获取每个电池包模组的当前电量,从而电源管理装置8能够根据参数检测模块的输出的状态参数依次调节第一电池包模组101和第二电池包模组201的为驱动机构5供电。
具体的,在主开关9闭合的情况下,当第一开关单元102为连通状态、第二开关单元202为断开状态,仅所述第一电池包模组101向所述驱动机构5供电。在主开关9闭合的情况下,当第一开关单元102为断开状态、第二开关单元202为连通状态,仅所述第二电池包模组201向所述驱动机构5供电。在本实施例中,在主开关9闭合的情况下,所述第一开关单元102 和所述第二开关单元202中仅有一个处于连通状态,另一个处于断开状态,从而第一开关单元102和第二开关单元202在时间上能先后向驱动机构5供电。在一些具体的实施方式中,当第一电池包模组101和第二电池包模组201其中一个电量低于第一预设值时,电源管理装置8根据参数检测模块获取的第一电池包模组101和第二电池包模组201的电量信号,控制第一电池包模组101和第二电池包模组201其中另一个供电,当然电源管理装置8也可以根据参数检测模块获取的第一电池包模组101和第二电池包模组201的其他状态参数,例如:电压、电池包温度,控制第一开关单元102和第二开关单元202的连通或断开。
在一个具体的实施方式中,所述电源管理装置8控制所述第二电池包模组201优先于所述第一电池包模组101供电时,所述电源管理装置8控制所述第一开关单元102为断开状态、第二开关单元202为连通状态,当所述第二电池包模组201的电量低于第一预设值时,所述电源管理装置根据所述参数检测模块的输出控制所述第一开关单元102为连通状态、第二开关单元202为断开状态,使所述第一电池包模组101供电。

具体的,在本实施例中,所述电源管理装置8还包括:充电控制模块,用于管理所述第一电池包模组101和所述第二电池包模组201的充电顺序,所述充电控制模块包括用于判断是否满足充电条件的判断单元,在满足所述充电条件的情况下,所述充电控制模块控制所述第一开关单元102和所述第二开关单元202其中一个为连通状态或两个均为连通状态。
进一步的,所述第一电池包模组101和所述第二电池包模组201的充电顺序可以是:第一电池包模组101优先于第二电池包模组201充电,即充电控制模块依次调节所述第一开关单元102、第二开关单元202为连通状态;第二电池包模组201优先于第一电池包模组101充电,即充电控制模块依次调节所述第二开关单元202、第一开关单元102为连通状态;第一电池包模组101和第二电池包模组201同时充电,即充电控制模块调节所述第二开关单元202和第一开关单元102均为连通状态。
在本实施例中,所述充电控制模块包括用于判断是否满足充电条件的判断单元。所述充电条件包括:1、所述主开关9是否断开;2、所述整机充电接口是否接入充电电源。当所述主开关9为断开状态、所述整机充电接口接入充电电源时,则满足充电条件,充电控制模块能控制第一开关单元102和第二开关单元202其中一个为连通状态或控制第一开关单元102和第二开关单元202均为连通状态。所述充电条件可以进一步包括:3、第一电池包模组101和第二电池包模组201的电量是否低于第二预设值,判断单元能够基于参数检测模块输出的第一电池包模组101和第二电池包模组201电量是否低于第二预设值判断是否满足充电条件,若低于第二预设值,则满足充电条件,从而防止过充电。
在一些可能的实施方式中,所述充电控制模块控制所述第一电池包模组101和所述第二电池包模组201其中电量小的优先于其中另一个充电时,所述充电控制模块控制所述第一开关单元102和所述第二开关单元202其中一个为连通状态,其中另一个为断开状态;当所述第一电池包模组101和所述第二电池包模组201其中一个电量达到第二预设值时,所述充电控制模块根据所述参数控制模块的输出控制所述第一开关单元102和所述第二开关单元202其中一个为断开状态,其中另一个为连通状态,使所述第一电池包模组101和所述第二电池包模组201其中另一个充电。在本实施例中,充电控制模块根据参数检测模块获取的第一电池包模组101和第二电池包模组201的电量,控制电量小的电池包模组优先充电,当第一电池包模组101和第二电池包模组201其中一个电量达到第二预设值时,充电控制模块再切换其中另一个电池包模组充电。
在一个优选的实施方式中,所述充电控制模块控制所述第一电池包模组101优先于所述第二电池包模组201充电时,所述充电控制模块控制所述第一开关单元102为连通状态、所述第二开关单元202为断开状态,当所述第一电池包模组101电量达到第二预设值时,所述电源管理装置8根据所述参数检测模块的输出控制所述第一开关单元102为断开状态、第二开关单元202为连通状态,使所述第二电池包模组201充电。
在一些可能的实施方式中,该参数检测模块检测还可以获取每个电池包模组的额定电量,充电控制模块能够计算出每个电池包模组的待充电量,待充电量为额定电量与当前电量的差值,然后确定出每个电池包模组分别对应的预设充电时间,从而在第一开关单元102和第二开关单元202之间通过设定控制时间,进行充电切换。例如,第一电池包模组101优先于第二电池包模组201充电,充电控制模块控制第一开关单元102为连通状态、第二开关单元202为断开状态。充电控制模块根据参数检测模块输出当前电量和额定电量的差值,计算出第一电池包模组101的待充电量,进而确定出第一电池包模组101对应的预设充电时间。 充电控制模块在达到预设充电时间后,控制第一开关单元102为断开状态、第二开关单元202为连通状态,使得第二电池包模组201开始充电。
在本说明书中,所述电源管理装置8包括:比较模块,用于比较所述第一电池包模组101的电压和所述第二电池包模组201的电压的差值是否低于第三预设值,若不低于,则所述充电控制模块控制所述第一开关单元102和所述第二开关单元202的状态相反,即其中一个为所述连通状态,其中另一个为所述断开状态。
所述比较模块用于比较第一电池包模组101的电压和所述第二电池包模组201的电压的差值,充电控制模块基于上述两者的差值判断是否满足并联互充的条件。若第一电池包模组101的电压和所述第二电池包模组201的电压的差值不低于第三预设值,则不满足并联互充的条件,从而充电控制模块控制所述第一开关单元102和所述第二开关单元202的状态相反,即其中一个为所述连通状态,其中另一个为所述断开状态。所述第三预设值可以是零,也可以是接近于零的数值。第一电池包模组101和所述第二电池包模组201在不满足并联互充的条件下,第一电池包模组101和第二电池包模组201之间具有较大的电势差,通过调节第一开关单元102和第二开关单元202的状态相反,能够防止第一电池包模组101和第二电池包模组201互相充电,延长电池的寿命。
在一些可能的实施方式中,所述充电控制模块控制所述第一电池包模组101和所述第二电池包模组201中其中电量小的优先于其中另一个充电时,所述充电控制模块控制第一开关单元102和第二开关单元202其中一个为连通状态,其中另一个为断开状态;当所述第一电池包模组101的电压和所述第二电池包模组201的电压的差值低于第三预设值时,所述充电控制模块能根据所述参数检测模块的输出控制所述第一开关单元102和所述第二开关单元202均为连通状态,使所述第一电池包模组101和所述第二电池包模组201并联,可以同时充电。
在一个具体的实施方式中,所述第一开关单元102和所述第二开关单元202为单向导通开关器件。优选的,第一开关单元102和第二开关单元202为MOS管,电流能够单向流通,防止回流。第一开关单元102和第二开关单元202均具有控制信号输入端,在电源管理装置8可以通过控制信号输出端导通第一开关单元102和第二开关单元202。
在一个具体的实施方式中,如图7所示,所述第二供电装置200包括单控制器,所述单控制器分别连接第二电池包模组201中的每个电池包7,所述单控制器与所述电源管理装置电性连接以实现对第二电池包模组201中电池包7的放电控制和充电控制,所述单控制器用于分别检测所述第二电池包模组201中每个电池包7的安全性能参数,所述安全性能参数包 括:放电电量、充电电流、电压、电池包温度、电池包电量,从而防止第二电池包模组201中任意电池包7发生过充电、过放电、过电流和温度异常的现象。
为了保证第二供电装置200中的第二电池包模组201方便从盒体1中取出、更换,在一个具体的实施方式中,所述第二电池包模组201中的电池包7沿水平方向或沿垂直方向或沿与垂直方向呈0至60度夹角的方向插入至所述盒体1中。如此,可以便于电池包7更换时插入盒体1中。
如图5和图6所示,所述盒体1包括:第一安装体2和第二安装体3,所述第一安装体2和所述第二安装体3连接后形成完整的盒体1,所述第一安装体2和所述第二安装体3可拆卸连接。具体的,第一安装体2和第二安装体3可以通过转动的方式实现对接和打开,从而便于对盒体1中电池包7进行更换。例如,第一安装体2和第二安装体3的下端可以通过铰链的连接方式连接,以使第一安装体2和第二安装体3之间实现转动。当然,第一安装体2和第二安装体3也可以通过卡扣方式或其他方式实现对接和开启。
盒体1内部可以设置有插接件,当电池包7位于盒体1内部时,电池包7与插接件相对接,以实现将电池包7的电流通过插接件向外输出,当第二电池包模组201与该插接件相对接时,与第一电池包模组101串联连接。当盒体1中电池包7电量耗尽时,可以将第一安装体2打开,从而方便的将电量耗尽的电池包7取出,再安装入准备好的电量满的电池包7,如此,电动车就能够继续使用行使,避免了电动车在没电时,必须停下来来充电的问题。
在一个具体的实施方式中,第一安装体2和第二安装体3对接后形成的所述盒体1具有第一侧面和第二侧面,所述第一侧面和所述第二侧面可以是相背对的侧面,也可以是相邻的侧面,本申请不作特别限定。优选的,所述第一侧面和所述第二侧面为相背对的两个侧面。所述第一侧面上具有第一通风格栅13,所述第二侧面上具有第二通风格栅14,所述盒体1内部设置有挡水件6,包括第一挡水件和第二挡水件。具体的,第一挡水件与第一侧面连接后形成第一蓄水室,第一蓄水室底部封闭,顶部敞开,所述第一通风格栅13与第一蓄水室、盒体1的腔室相连通形成第一气流通道。第二挡水件与所述第二侧面连接后形成第二蓄水室,第二蓄水室底部封闭,顶部敞开,所述第二通风格栅14与第二蓄水室、盒体1容纳腔室相连通形成第二气流通道。
第一挡水件和第二挡水件具有相同的结构,均具有相对的左、右两侧,以及相对的上、下两端,其左右两侧以及下端固定在第一侧面或第二侧面上。第一挡水件的上端与第一侧面之间敞开,从而第一挡水件与第一侧面形成的第一蓄水室仅通过上端与盒体1内部腔室连通。第一挡水件与第一通风格栅13对应设置,从而第一蓄水室能通过第一通风格栅13与外界连通。第二挡水件的上端与第二侧面之间敞开,从而第二挡水件与第二侧面形成的第二蓄水室 仅通过上端与盒体1内部腔室连通。第二挡水件与第二通风格栅14对应设置,从而第二蓄水室能通过第二通风格栅14与外界连通。
在本实施例中,如图6所示,第一通风格栅13上的格栅条可以朝向第一蓄水室的下端,第二通风格栅14上的格栅条可以朝向第二蓄水室的下端,如此,当雨水留在第一通风格栅13和第二通风格栅14上时,雨水能够沿着格栅条向下滑落,从而滑落至第一通风格栅13与第一挡水件之间或者第二通风格栅14与第二挡水件之间,从而在第一通风格栅13和第一挡水件之间蓄积的水或者在第二通风格栅14和第二挡水件6之间蓄积的水能够通过格栅排出。
电池包7在使用过程中产生热量后,外部气流能够通过第一气流通道和第二气流通道进入至盒体1内部,与盒体1内部的气体进行交换,从而可以有效降低电池包7的温度,第二供电装置200的盒体1能够有效进行内部散热。另外,外部雨水在通过第一通风格栅13、第二通风格栅14进入至盒体1后,蓄积的水将通过第一通风格栅13、第二通风格栅14排出,从而使得该第二供电装置200具备防雨、防水的功能。本申请实施例提供的第二供电装置200在保证电池包7方便更换以及电池包7内部散热的前提下有效避免了雨水进入盒体1而对电池包7造成的影响,从而该第二供电装置200在外置于电动车时,能够适应于各种环境。
本申请实施例提供的电动车,在其内部配置的第一供电装置的基础上还加装有第二供电装置,第二供电装置和第一供电装置并联连接,从而第一供电装置和第二供电装置均可以单独用于给整机供电,提高了电动车的使用时间,以及续航里程。电动车还设置有用于管理第一供电装置和第二供电装置放电顺序和充电顺序的电源管理装置,从而可以优先选择第二供电装置放电,第一供电装置充电。当第二供电装置的电量用完,可以将第二电池包模组从盒体中拆卸取出,更换为电量充足的电池包再加装在盒体上,无需任何充电等待时间。
