下面参考附图描述根据本公开实施例的集成式电机控制器1。
如图1-图10所示,根据本公开实施例的集成式电机控制器1包括充电连接件100、电池连接件110、第一充电电路200和第二充电电路300。
第一充电电路200分别与充电连接件100和电池连接件110连接,第一充电电路200具有第一控制开关210,第一控制开关210控制第一充电电路200的通断,第二充电电路300分别与充电连接件100和电池连接件110连接,第二充电电路300具有升压模块310和第二控制开关320,第二控制开关320控制第二充电电路300的通断。
举例而言,第一控制开关210和第二控制开关320可以为接触器,充电连接件100和电池连接件110可以为插接件。并且,充电连接件100可以与外界的充电设备连接,例如充电连接件100可以与充电桩连接,电池连接件110可以与车辆的电池包连接。
根据本公开实施例的集成式电机控制器1,通过将第一充电电路200分别与充电连接件100和电池连接件110连接,第一充电电路200具有控制第一充电电路200通断的第一控制开关210,这样,当充电连接件100与电压较高(电压不低于750V)的充电设备连接时,例如,当充电连接件100与充电电压为750V的充电设备连接时,第一控制开关210可以处于连通状态,以使电流可以通过第一充电电路200直接为电池连接件110充电,实现电池包的快速充电。
另外,第二充电电路300分别与充电连接件100和电池连接件110连接,第二充电电路300具有升压模块310和控制第二充电电路300通断的第二控制开关320,这样,当充电连接件100与电压较低(电压低于750V)的充电设备连接时,例如,当充电连接件100与充电电压为470V的充电设备连接时,第二控制开关320可以处于连通状态,以使电流可以流经第二充电电路300,且升压模块310可以对第二充电电路300的电压进行升压,以使第二充电电路300的电压可以升压至630V以上,进而可以对电池包进行快速充电。
并且,当充电连接件100没有连接充电设备时,第一控制开关210和第二控制开关320都可以处于断开状态;当充电连接件100连接充电设备时,集成式电机控制器1可以检测充电设备的输出电压,若充电电压较高,第一控制开关210连通且第二控制开关320断开,充电设备可以通过第一充电电路200直接为电池包进行充电;若充电电压较低,第二控制开关320连通且第一控制开关210断开,充电设备可以通过第二充电电路300的升压模块310升压后再为电池进行充电。
这样,第一控制开关210和第二控制开关320一般不会同时闭合,以减小充电时的电压波动,有利于保持充电电压的稳定,并且通过控制第一控制开关210和第二控制开关320的闭合与断开,能够使充电连接件100通过不同的充电电路与电池连接件110连接,以保证充电电压足够大,实现电池包的快速充电,又能够防止充电电压过大而使电池包损坏,安全性高。由此,本公开实施例的集成式电机控制器1适用于多种充电设备,且无论充电设备输出电压高低,都能够实现电池包的快速充电,充电更加方便且时间短。
如此,根据本公开实施例的集成式电机控制器1能够适用于不同的充电电压,具有通用性高和充电方便等优点。
在本公开的一些具体实施例中,如图1所示,集成式电机控制器1还包括交流充放电连接件400和交流充放电电路410。
交流充放电电路410具有车载充电器(On Board Charger,OBC)411和直流转换器(DC/DC)412,车载充电器411与交流充放电连接件400连接,直流转换器412与电池连接件110连接。
其中,车载充电器411能够根据电池包所需的充电电流和电压,动态调整充电电压和充电电流参数,便于对电池包进行充电且能够保护电池包。并且,车载充电器411可以连接有车内放电连接件420,以对乘客需要交流充电的物品进行充电。
这样,通过交流充放电连接件400能够连接交流电,并通过交流电为电池充电,且车载充电器411能够调节交流电压的参数,改变充电电压的大小同时将交流电转换为直流电,便于为电池包充电。
并且,直流转换器412能够对经过车载充电器411的直流电进行稳压和稳流,同时可以将低压充电电流转换为高压充电电流,以实现电池包的快速充电。另外,电池包也可以通过交流充放电电路410向交流充放电连接件400传输交流电,从而使交流充放电连接件400可以为车内上的使用交流电的电器进行供电。
在本公开的一些具体实施例中,充电连接件100为直流充电连接件100,升压模块310包括电机线圈312和电控桥臂316。
电机线圈312为驱动电机311的线圈,电机线圈312接入第二充电电路300,电控桥臂316为电机控制器313的IGBT模块315的桥臂,电控桥臂316与电机线圈312连接。这样,经过第二充电电路300的电流可以依次流经电机线圈312和电控桥臂316,以通过电机线圈312和电控桥臂316组成升压模块310,为第二充电电路300的电流进行加压,实现电池的快速充电。
这样,升压模块310和电机控制器313共用了电机控制器313的IGBT模块315的桥臂,升压模块310和驱动电机311共用了电机线圈312,无需额外设置电感、二极管以及开关器件等电子器件,减少了零件数量,降低了生产成本,从而有利于减小了电动总成2的体积。
并且,由于驱动电机311一般为三相电机,即驱动电机311的电机线圈312为三组,通过将驱动电机311的三组电机线圈312都应用于升压模块310,能够减小第二充电电路300产生的纹波电流的概率,进一步地保证了电池包的输入电压的稳定性。
在本公开的一些具体实施例中,集成式电机控制器1还包括升压电容640和平波电容630。
升压电容640分别与充电连接件100、电池连接件110和IGBT模块315连接,平波电容630分别与IGBT模块315和电池连接件110连接。其中,当电池包给IGBT模块315供电用于车辆驱动时,电池包的电流会先经过平波电容630,可以吸收流向电池连接件110的电流中的纹波电流和电流储能,使电池包对IGBT模块315供电时滤波并保持电压电流稳定;当升压充电时,电机线圈312升压后的电流经IGBT模块315后流入平波电容630,使平波电容630吸收升压后的电路纹波电流和电流储能,以使充电时的电流流向电池包时电压稳定。
这样就保持电池连接件110的电压稳定,从而保持电池包的充电电压和放电电压的稳定。但是平波电容630和电机线圈形成了一个L/C电路,通过设置升压电容640能够吸收从充电连接件100输入的电流中的纹波电流,对从充电连接件100输入的电流进行滤波,以使从充电连接件100输入的电流的电压稳定。
在本公开的一些具体实施例中,如图6所示,集成式电机控制器1还包括电容壳体500、电池正极连接片510、电池负极连接片520、输出连接片530、充电正极连接片540和充电负极连接片550。
升压电容640和平波电容630安装于电容壳体500,电池正极连接片510安装于电容壳体500,且电池正极连接片510分别与电池连接件110的正极和平波电容630的正极连接,电池负极连接片520安装于电容壳体500,且电池负极连接片520与电池连接件110的负极和平波电容630的负极连接,输出连接片530安装于电容壳体500,且输出连接片530分别与平波电容630和IGBT模块315连接,充电正极连接片540安装于电容壳体500分别,且充电正极连接片540与充电连接件100的正极和升压电容640连接,充电负极连接片550安装于电容壳体500,且充电负极连接片550分别与充电连接件100的负极、升压电容640、平波电容630和电池负极连接片520连接。
举例而言,为了加强升压电容640和平波电容630的散热,电容壳体500上有散热金属板591和导热泥592,散热金属板591与电容壳体500贴合,导热泥592的第一表面5921与散热金属板591贴合,导热泥592的第二表面5922与电控箱体贴合。也就是说,导热泥592设于散热金属板591和电控箱体之间,便于电容的热量通过导热泥592为介质传导到电控箱体上给电容散热。为了便于线束走线,电容壳体500还可以构造有线束固定槽505和扎带孔506等结构。
将升压电容640和平波电容630可以集成到电容壳体500内,便于布置同时节省装配空间,由此,电容壳体500可以将电池正极连接片510、电池负极连接片520、输出连接片530、充电正极连接片540和充电负极连接片550进行固定,且电池正极连接片510、电池负极连接片520、输出连接片530、充电正极连接片540和充电负极连接片550可以露出于电容壳体500,以便于电池包和平波电容630连接,以及升压电容640与充电连接件100连接,连接更加可靠,装配效率更高。
在本公开的一些具体实施例中,如图6所示,电容壳体500具有沿电容壳体500的周向首尾相连的第一侧边501、第二侧边502、第三侧边503和第四侧边504,电池正极连接片510、电池负极连接片520和充电负极连接片550安装于第一侧边501,输出连接片530安装于第二侧边502,充电正极连接片540安装于第三侧边503。
这样,可以将电池正极连接片510、电池负极连接片520和充电负极连接片550与输出连接片530、充电正极连接片540间隔开,避免多个零部件之间的位置干涉,便于安装,同时可以避免多个部件在接电时发生短路,保持电路连通。
在本公开的一些具体实施例中,如图5所示,集成式电机控制器1还包括电路安全保护件600。
电路安全保护件600安装于电容壳体500,且电路安全保护件600分别与电池负极连接片520和平波电容630的负极连接,举例而言,电路安全保护件600可以为保险丝,集成式电机控制器1还包括负极输入片590,电路安全保护件600的两端分别与负极输入片590和电池负极连接片520连接,电池负极连接片520和平波电容630的负极连接,电池负极连接片520通过电路安全保护件600和负极输入片590与平波电容630的负极连接,其中电池负极连接片520安装于第一侧边501。
由此,当经过电池负极连接片520的电流和平波电容630的电流过大,导致电路出现过流而温度升高的情况,电路安全保护件600可以断开,以切断电路的电流,进而可以避免电池包损坏,有利于提高电池包充放电时的安全性。
在本公开的一些具体实施例中,如图4所示,集成式电机控制器1还包括充电端磁环610和电池端磁环620。
充电端磁环610安装于电容壳体500的外周面,充电连接件100通过中间连接件120与充电正极连接片540和充电负极连接片550连接,充电端磁环610套设于中间连接件120,电池端磁环620安装于电容壳体500的外周面,电池端磁环620套设于电池连接件110。
这样,充电端磁环610能够阻挡外界对中间连接件120的电磁干扰,电池端磁环620能够阻挡外界对电池连接件110的电磁干扰,进而可以避免外界对电池的电磁干扰,且使电池包在充放电时的电电压更加稳定。
而且,电容壳体500上可以设有安装电池端磁环620的磁环安装位593,以使充电端磁环610和电池端磁环620都可以集成到电容壳体500上,进而能够提高电容壳体500的集成度,使电容壳体500的结构更加紧凑,节省装配空间,而且电容壳体500的防电磁干扰效果更好。
结合附图举例描述集成式电机控制器1的工作过程:
电池包对驱动电机供电时:电池包的电流通过电池连接件110,电池连接件110的正极通过电池正极连接片510流向平波电容630,再经输出连接片530给IGBT模块315供电,经过IGBT模块315转换为交流电后流向驱动电机311;电池连接件110的负极通过电池负极连接片520经过电路安全保护件600和负极输入片590流向平波电容630后,再经输出连接片530给IGBT模块315供电,经过IGBT模块315转换为交流电后流向驱动电机311。
对电池包充电且充电电压小于750V时:充电电流通过充电连接件100经充电端磁环610后,充电连接件100的负极经充电负极连接片550流向电池负极连接片520,再经电池连接件110流向电池包;充电连接件100的正极经流向电机线圈312和IGBT模块315,在电机线圈312处经过升压,升压后的电流流向电池正极连接片510,再经电池连接件110流向电池包。
在本公开的一些具体实施例中,如图3、图4、图7和图8所示,集成式电机控制器1还包括箱体700、驱动板730、控制板740和电源功率器件750。
箱体700的厚度方向的第一侧701设有第一腔室710,且箱体700的厚度方向的第二侧702设有第二腔室720,IGBT模块315安装于第一腔室710,驱动板730和控制板740安装于第一腔室710,驱动板730分别与IGBT模块315和控制板740连接,电源功率器件750安装于第二腔室720且与控制板740连接。控制板740与整车控制器连接。
也就是说,第一腔室710和第二腔室720分别设于箱体700的厚度方向的两侧,这样,第一腔室710和第二腔室720之间的侧壁可以将IGBT模块315、驱动板730、控制板740四者与电源功率器件750分隔开,有效地降低了电源功率器件750对IGBT模块315、驱动板730和控制板740的电磁干扰,提高电控的有效性,而且,IGBT模块315、驱动板730、控制板740和电源功率器件750都能够集成到箱体700上,箱体700可以固定IGBT模块315、驱动 板730、控制板740和电源功率器件750,结构更加紧凑,有利于减小集成式电机控制器1的整体体积,便于安装。
当然,第一腔室710内可以分设于多个小腔室,第二腔室720内也可以分设为多个小腔室,电源功率器件750设有AC电感、DC电感、MOS管和电感变压器,AC电感、DC电感、MOS管和电感变压器放置于第二腔室720的小腔室内,这样进一步地避免了多个功率模块之间的电磁干扰,有利于提高电磁兼容性。
并且,第一腔室710和第二腔室720之间可以设有过线孔,线束可以穿过过线孔以连通第一腔室710的电器件和第二腔室720的电器件,以便于第一腔室710内的零部件与第二腔室720内的零部件之间的电连接。
举例而言,控制板740、驱动板730和IGBT模块315依次层叠设置,控制板740和驱动板730之间设有电磁屏蔽板,防止IGBT模块315工作时对控制板740产生干扰。
其中,集成式电机控制器1可以设有上盖760和下盖770,上盖760可以用于封盖第一腔室710,进而可以保护第一腔室710内的零部件,例如,IGBT模块315、驱动板730和控制板740,避免外界零部件与IGBT模块315、驱动板730和控制板740等发生位置干涉,同时下盖770可以用于封盖第二腔室720,进而可以保护电源功率器件750,避免其他零部件与电源功率器件750发生位置干涉。
在本公开的一些具体实施例中,如图9和图10所示,集成式电机控制器1还包括水道盖板800。其中,水道盖板800可以通过摩擦焊与箱体700连接成一体。
水道盖板800设有第三水道810,箱体700设有第一水道712和第二水道711,水道盖板800与箱体700连接,且水道盖板800封盖第一水道712和第二水道711,第三水道810分别与第一水道712和第二水道711连通。其中,第一水道712内的冷却液流入第三水道810为IGBT模块315散热,第三水道810内的冷却液流入第二水道711为电源功率器件750散热。
也就是说,第三水道810、第一水道712和第二水道711形成了一个连通的水道,第三水道810、第一水道712和第二水道711内的冷却液可以共用,即第三水道810、第一水道712和第二水道711内的冷却液可以互相流通,IGBT模块315可以对第三水道810进行密封,避免了第三水道810、第一水道712和第二水道711内的冷却液泄漏,且第三水道810内的冷却液可以为IGBT模块315进行降温,避免高温损坏IGBT模块315,同时使IGBT模块315处于低温的状态,保持其工作的稳定性。
并且,通过水道盖板800可以对第一水道712和第二水道711进行密封,避免第一水道712和第二水道711内的冷却液漏出,且第二水道711内的冷却液可以通过第二水道711的外壁与电源功率器件750进行换热,进而可以降低电源功率器件750的温度,使电源功率器件750保持在一个低温状态,进而可以提高电源功率器件750的工作稳定性,避免高温损坏电源功率器件750。
而且,第三水道810、第一水道712和第二水道711连通,冷却液的流动路径更长,第一水道712内的冷却液可以流入第三水道810内为IGBT模块315进行散热,第三水道810内的冷却液也可流入第二水道711内为电源功率器件750进行散热,有利于提高冷却液的利用率,且使冷却液与电源功率器件750和IGBT模块315充分换热。
进一步地,如图9所示,第三水道810包括沿其长度方向排布的多个冷却腔811,IGBT模块315为多个,且与多个冷却腔811与多个IGBT模块315一一对应,这样,每个冷却腔811可以为与其对应的IGBT模块315进行换热,进而可以为IGBT模块315散热,且水道盖板800设有环绕水道盖板800的密封槽840,密封槽840内设有密封圈,密封圈填充IGBT模块315 和水道盖板800之间的间隙,每个IGBT模块315可以对与其对应的冷却腔811的密封效果更好,保证第三水道810的密封性,避免冷却腔811内的冷却液漏出。
并且,每个冷却腔811包括进水口812和出水口813,相邻两个冷却腔811的相邻的进水口812和出水口813连通,第一水道712连通至与其相邻的冷却腔811的进水口812,第二水道711连通至与其相邻的冷却腔811的出水口813,水道盖板800的朝向箱体700的一侧设有至少一个隔板820,隔板820阻止相邻的进水口812和出水口813与第二水道711连通。
也就是说,隔板820可以隔断第二水道711和第三水道810,相邻的冷却腔811内的冷却液可以通过进水口812和出水口813保持连通,这样可以使第三水道810内的冷却液能够流经所有的冷却腔811,避免了冷却液直接流向第二水道711而导致部分冷却腔811内没有冷却液,有利于提高第三水道810对IGBT模块315的冷却效果,使多个IGBT模块315都能够与冷却腔811稳定换热。
举例而言,最外侧的两个冷却腔811中的其中一个可以通过出水口813与第二水道711连通,且两个冷却腔811中的另一个通过进水口812与第一水道712连通,这样,第一水道712内的冷却液可以通过最外侧的冷却腔811的进水口812进入第三水道810,且通过另一个冷却腔811的出水口813流回第二水道711,进而实现冷却液在第一水道712、第三水道810和第二水道711内的循环,且冷却液能够完全流经第二水道711和第三水道810,有利于提高冷却液的利用率。
在本公开的一些具体实施例中,如图7所示,第二水道711包括过渡段713和环形段714。
过渡段713连通至与其相邻的冷却腔811的出水口813,环形段714围绕电源功率器件750并为电源功率器件750散热,环形段714的第一端715与过渡段713的一端连接,且环形段714的第二一端716设有出水孔717,环形段714的外壁为电源功率器件750散热。
由此,冷却液先流入第一水道712,再流入与第一水道712相邻的冷却腔811,然后第三水道810内的冷却液沿从第一水道712至过渡段713的方向依次流经多个冷却腔811,接下来冷却液从与过渡段713相邻的冷却腔811流向过渡段713,最后由过渡段713流向环形段714,从而环形段714的出水孔717排出。
并且,环形段714与电源功率器件750的接触面积更大,且环形段714的结构更加紧凑,占用空间更小,利用环形段714为电源功率器件750散热可以提高第二水道711与电源功率器件750的换热效果,进而使电源功率器件750能够快速降温,散热效果更好。
另外,环形段714的深度大于第一水道712的深度以及过渡段713的深度,这样一方面可以使环形段714的容积更大,环形段714内的冷却液可以更多,进而提高环形段714对电源功率器件750的散热效果,另一方面可以使第一水道712与第三水道810之间的过渡更加平缓,以及过渡段713与第三水道810之间的过渡更加平缓,冷却液在第二水道711和第三水道810之间循环流动更加平缓,以使冷却液能够充分与电源功率器件750和IGBT模块315进行换热,进一步提高电源功率器件750的散热效果和IGBT模块315的散热效果。
举例而言,环形段714呈“U”形环绕电源功率器件750的电感变压器散热,电源功率器件750的MOS管、AC电感和DC电感位于“U”形环形段714外,且与环形段714的外壁贴合。
在本公开的一些具体实施例中,如图7和图8所示,集成式电机控制器1还包括进水管900和出水管910。
进水管900安装于箱体700且与第一水道712连通,出水管910安装于箱体700且与出水孔717连通,这样,冷却液可以通过进水管900流入第一水道712、第三水道810和第二水道711内,且冷却液可以通过出水孔717和出水管910排出,也就是说,当冷却液与电源功率器件750和IGBT模块315充分换热后,第一水道712、第三水道810和第二水道711内的冷却 液可以通过出水管910排出,并通过进水管900为第一水道712、第三水道810和第二水道711进行冷却液的补充,保持第一水道712、第三水道810和第二水道711内的冷却液充足,且使冷却液的温度较低,以提高第二水道711和第三水道810对电源功率器件750和IGBT模块315的冷却效果。
另外,进水管900和出水管910垂直设置,例如,进水管900可以设于箱体700的一侧且出水管910可以设于箱体700的相邻一侧,这样,可以避免进水管900和出水管910位置干涉,便于布置,且第二水道711和第三水道810的长度可以设置得较长,以使第二水道711和第三水道810能够覆盖箱体700的绝大部分,进一步提高了第二水道711和第三水道810对电源功率器件750和IGBT模块315的冷却效果,同时第二水道711和第三水道810内的冷却液能够降低箱体700的温度,进而还可以为安装于箱体700的其他零部件进行散热,以提高箱体700的散热效果。
举例而言,由于上述布置导致出水管910比较长,因此可以增加压板911,压板911安装于箱体700,且于箱体700共同夹持出水管910,以固定出水管910相对于箱体700的位置。
根据本公开另一个实施例的集成式电机控制器1包括充电连接件100、电池连接件110、第一充电电路200及第二充电电路300。
充电连接件100用于连接充电设备,例如充电连接件100可以与充电桩连接。电池连接件110用于连接电池包,第一充电电路200分别与充电连接件100和电池连接件110连接,第二充电电路300分别与充电连接件100和电池连接件110连接,第二充电电路300具有升压模块310,第一充电电路200和第二充电电路300择一导通。
其中,通过将第一充电电路200分别与充电连接件100和电池连接件110连接,当充电连接件100与电压较高(电压不低于750V)的充电设备连接时,例如,当充电连接件100与充电电压为750V的充电设备连接时,第一充电电路200处于导通状态,以使电流可以通过第一充电电路200直接为电池连接件110充电,实现电池包的快速充电。
另外,第二充电电路300分别与充电连接件100和电池连接件110连接,第二充电电路300具有升压模块310,这样,当充电连接件100与电压较低(电压低于750V)的充电设备连接时,例如,当充电连接件100与充电电压为470V的充电设备连接时,第二充电电路300处于导通状态,且升压模块310可以对第二充电电路300的电压进行升压,以使第二充电电路300的电压可以升压至630V以上,进而可以对电池包进行快速充电。
如此,根据本公开实施例的集成式电机控制器1能够适用于不同的充电电压,具有通用性高和充电方便等优点。
在本公开的一些实施例中,在充电设备提供的电压高于预设值时,第一充电电路(200)导通,此时第一充电电路200导通且第二充电电路300断开,充电设备可以通过第一充电电路200直接为电池包进行充电;在充电设备提供的电压不高于预设值时,第二充电电路300导通,此时第二充电电路300导通且第一充电电路200断开,充电设备可以通过第二充电电路300的升压模块310升压后再为电池进行充电。另外,当充电连接件100没有连接充电设备时,第一充电电路200和第二充电电路300都处于断开状态。
在本公开的一些具体实施例中,升压模块310包括电机线圈312和电控桥臂316,电机线圈312包括三组,电控桥臂316包括三相桥臂,三组电机线圈312的第一端分别连接三相桥臂的中点,三组电机线圈312的第二端均连接充电连接件100。这样,经过第二充电电路300的电流可以依次流经电机线圈312和三相桥臂,以通过电机线圈312和三相桥臂组成升压模块310,为第二充电电路300的电流进行加压,实现电池的快速充电。其中,通过使升压模块 310包括三组电机线圈312和三相桥臂,能够减小第二充电电路300产生的纹波电流的概率,进一步地保证了电池包的输入电压的稳定性。
下面参考附图描述根据本公开第二方面实施例的电动总成2,电动总成2包括根据本公开上述第一方面实施例的集成式电机控制器1。
具体地,参照图1,电动总成2还包括驱动电机311和变速器3,集成式电机控制器1的出水管910可以和变速器3的冷却液道连通,这样,集成式电机控制器1的水道内的冷却液可以给IGBT模块315和电源功率器件750散热后,再流向变速器3的冷却液道给驱动电机311和变速器3散热。驱动电机311的三相输出端与IGBT模块315连接,驱动电机311的线圈和充电连接件100连接。
