Description

电池加热装置、电池热调节方法、计算机可读存储介质以及电子设备 技术领域
本发明涉及汽车领域，尤其涉及一种电动汽车的电池加热装置、电池热调节方法、计算机可读存储介质以及电子设备。
 背景技术
随着对能源问题的关注，节能已成为热门话题。例如，随着电动汽车的普及，电动汽车的节能已成为重要的研究课题。
图1为传统技术中的一种电动汽车的发动机冷却回路的示意图。在该发动机冷却回路中，第二泵104从第二储液器102泵送冷却液并且驱动冷却液通过发动机水套。冷却液冷却发动机水套中的发动机，吸收热量且温度随之升高。发动机热量通过恒温器108分配。热量根据需要通过乘员舱加热芯110和/或散热器112，从而达到冷却发动机的目的。在大多数插电式混合动力汽车（PHEV）或混合动力汽车（HEV）中，当前的电池加热方法都涉及高压加热器，该加热器从电池中汲取电流，并将存储在电池中的电能转换成热量以预热电池。图2为普通电池加热回路的示意图。当需要加热电池时，高压加热器208将存储在电池中的电能转换成热负荷并加热电池。当电池需要冷却时，冷却器将冷却液中的热量吸收到空调（A/C）设备的两相流中。电池加热/冷却回路与发动机冷却回路分开工作。当发动机需要冷却时，大量的热量被释放到周围的空气中，并且发动机产生的热量不能被引导至电池加热回路，从而造成能量浪费。
在传统技术中，可以通过热交换器来实现发动机冷却回路与电池加热回路之间的热交换，以增加电池加热回路的温度并降低发动机冷却回路的温度。但是，热交换器的体积和质量较大，系统的整体重量和包装空间增加，并且增加了附加部件，从而导致制造成本较高。
针对传统技术中的上述问题，目前尚未提出有效的解决方案。

本发明的另一实施例提供了一种电池热调节方法。该方法可应用于上述实施例的装置中，并可以包括：获取第一液体和第二液体；将第一液体和第二液体混合以获得混合液体；以及将获得的混合液体传送至电池加热回路中，以调节电池的温度。
本发明的又一个实施例提供了一种计算机可读存储介质。该计算机可读存储介质可以存储计算机程序，且该计算机程序被配置为在运行期间执行上述方法实施例中的步骤。

 有益效果
通过本发明，三通阀将电池加热回路和发动机冷却回路连接在一起，将发动机冷却回路中的第一液体和电池加热回路中的第二液体混合，并将混合后的液体传送至电池加热回路，以加热电池。本发明不需要通过热交换器在电池加热回路和发动机冷却回路之间进行热交换，减少了系统的整体重量和包装空间，减少了额外的组件，并降低了成本，解决了现有技术中由于使用热交换器而导致的系统整体重量大、包装空间大和制造成本高的问题。

 本发明的实施方式
下面参考附图并结合实施例详细描述本发明。需要说明的是，在不冲突的情况下，本申请实施例中的特征可以相互组合。
需要注意的是，本发明的说明书和权利要求中的术语“第一”，“第二”以及附图中的类似表述用于区分相似的对象，不用于描述特定的顺序或优先顺序。
本实施例提供了一种电动汽车的电池加热装置。图3是根据本发明实施例的电池加热装置的结构框图。如图3所示，该装置包括电池加热回路32、发动机冷却回路34和三通阀36。三通阀36连接电池加热回路32和发动机冷却回路34，以混合发动机冷却回路34中的第一液体和电池加热回路32中的第二液体，并将混合液体传输到电池加热回路32，以加热电池加热回路32中的电池。
在本实施例中，第一液体和第二液体都可以是甘油（glycerol）、乙二醇（ethylene glycol）等。本发明不限制第一液体和第二液体的材料。第一液体可以与第二液体相同，或者不同于第二液体。两种液体可以以任何比例混合，且混合后没有任何物理或化学变化。混合液体可以用作加热电池的第一液体或用作冷却发动机的第二液体。
通过本发明，三通阀将电池加热回路和发动机冷却回路连接在一起，将发动机冷却回路中的第一液体和电池加热回路中的第二液体混合，并将混合后的液体传送至电池加热回路，并加热电池。因此不需要通过热交换器在电池加热回路和发动机冷却回路之间进行热交换，减少了系统的整体重量和包装空间，减少了额外的组件，并降低了成本，解决了现有技术中由于使用热交换器而导致的系统整体重量大、包装空间大、以及制造成本高的问题。
在可选实施例中，该装置还包括温度传感器，该温度传感器布置在电池加热回路中的电池406与电池加热回路中的第一泵404之间，并与三通阀连接。在本实施例中，图4是根据本发明的可选实施例的电动汽车的电池加热装置的示意图一。如图4所示，在电池加热回路中，第一泵404和电池406依次连接。温度传感器布置在第一泵404和电池406之间。三通阀412与电池加热回路连接。第一泵404泵送第一液体，使第一液体加热电池406。温度传感器在第一液体通过电池406之前检测第一液体的温度，并且三通阀412根据温度数据调节第一液体和第二液体的混合比，使流过电池406的第一液体温度适中。因此，可以省略热交换器，并且当需要加热电池时，可以从发动机回收废热。第一液体和第二液体的混合比可以为1：1（该值仅是一个可选的实施方式，该值可以利用温度传感器检测到的温度反馈进行控制，例如可以为1 ：2、2：1等）。
可选地，预先设置温度阈值。当温度传感器检测到的温度大于温度阈值时，三通阀412允许较少的第二液体与第一液体混合以加热电池406。当温度传感器检测到的温度小于温度阈值，三通阀412允许更多的第二液体与第一液体混合以加热电池。混合后的液体将行进很长的距离，并穿过多个组件，然后才能到达电池入口。因此，可以认为混合液体的温度是均匀的，并且由温度传感器检测到的温度表示电池加热回路中液体的平均温度。可选地，温度传感器也可以布置在第一储液器402和第一泵404之间或电池加热回路中的其他位置。
示例性地，该装置还包括三通阀控制器。三通阀控制器与温度传感器和三通阀412电连接。温度传感器将检测到的第一液体的温度反馈到三通阀控制器。三通阀控制器根据接收到的温度数据控制三通阀412的操作，从而调节从三通阀412流向电池加热回路的第二液体的流量，以调节第一液体和第二液体的混合比。三通阀412是能够根据三通阀控制器发送的控制指令进行动作的阀。
在可选的实施例中，三通阀412位于发动机冷却回路中的恒温器416和发动机冷却回路中的乘员舱加热芯414之间，其中三通阀412的第一端与电池加热回路中的高压加热器408连接，三通阀412的第二端与乘员舱加热芯414连接，三通阀412的第三端连接到恒温器416，电池加热回路中的冷却器410与发动机冷却回路中的第二储液器422连接。在本实施例中，如图4所示，在电池加热回路中，高压加热器408、冷却器410、第一储液器402、第一泵404和电池406依次连接，温度传感器位于第一泵404和电池406之间，三通阀412与高压加热器408连接。在发动机冷却回路中，发动机418和恒温器416依次与散热器424连接。恒温器416可以根据第二液体的温度自动调节进入三通阀412和散热器424的流量，以确保发动机在适当的温度范围内运行。第二液体在散热器424的芯中流动，空气穿过散热器的外部，并且第二液体通过向空气散发热量来降低温度，从而冷却发动机。
在本实施例中，当温度传感器检测到的温度低于温度阈值，并且发动机418产生的热量足以将电池加热到预定温度时，恒温器416使更多的第二液体通过三通阀412并使较少的第二液体通过散热器424。第一液体和第二液体的混合比由三通阀412控制，以便利用发动机418产生的热量加热电池406。该装置还包括恒温器控制器。恒温器控制器与恒温器416电连接。恒温器通过恒温器控制器发送的信号来控制通过三通阀的第二液体的流量。当发动机产生的热量不足以将电池406加热到预定温度时，恒温器416禁止第二液体流过散热器424，并且高压加热器408将存储在电池406中的电能转换为热负载以加热电池406。高压加热器408可包括电阻丝。电阻丝缠绕在容纳第一液体的管道上并连接到电池406。当电流流过电阻丝时，会产生热量以升高第一液体的温度并加热电池406。当电池406温度太高时，三通阀412禁止第二液体与第一液体混合，并且冷却器410通过降低第一液体的温度以冷却电池406。冷却器可包括蒸发器，以通过降低第一液体的温度来冷却电池406。
在可选实施例中，三通阀位于发动机冷却回路中的恒温器416和发动机冷却回路中的乘员舱加热芯414之间。电池加热回路包括依次连接的冷却器410、第一储液器402、第一泵404和电池406。三通阀412的第一端连接至冷却器410。三通阀412的第二端连接到乘员舱加热芯414。三通阀412的第三端连接到恒温器416。电池加热回路中的冷却器410与发动机冷却回路中的第二储液器422连接。在本实施例中，图5是根据本发明的可选实施例的电动汽车的电池加热装置的示意图二。如图5所示，在电池加热回路中，冷却器410、第一储液器402、第一泵404和电池406依次连接。温度传感器设于第一泵404和电池406之间。三通阀412与冷却器410连接。在发动机冷却回路中，第二储液器422、第二泵420、发动机418、恒温器416和散热器424依次连接。恒温器416、三通阀412、乘员舱加热芯414和第二储液器422依次连接。通常，由发动机418产生的热量足以将电池加热至预定温度，因此可以省略高压加热器408，并且三通阀412直接连接至冷却器410。当温度传感器检测的温度大于温度阈值时，三通阀412允许较少的第二液体与第一液体混合以加热电池。当由温度传感器检测到的温度小于温度阈值时，三通阀412允许更多的第二液体与第一液体混合以加热电池，取消了高压加热器408，从而降低了成本，减小了封装空间，并降低了系统复杂度。
在可选实施例中，三通阀412位于发动机冷却回路中的恒温器416与发动机冷却回路中的发动机418之间，三通阀412的第一端连接至电池加热回路中的高压加热器408。三通阀412的第二端连接至发动机418。三通阀412的第三端连接到恒温器416。电池加热回路中的冷却器410连接至发动机冷却回路中的第二储液器422。在本实施例中，图6是根据本发明的可选实施例的电动汽车的电池加热装置的示意图三。如图6所示，在电池加热回路中，高压加热器408、冷却器410、第一储液器402、第一泵404和电池406依次连接。温度传感器位于第一泵404和电池406之间。三通阀412连接到高压加热器408。在发动机冷却回路中，三通阀412、恒温器416、乘员舱加热芯414、第二储液器422、第二泵420和发动机418依次连接，并且恒温器416、乘员舱加热芯414和散热器424依次连接。三通阀412被直接引入发动机冷却回路中。三通阀412直接连接至发动机418，从而由发动机418产生的热量直接通过三通阀，而无需恒温器416的控制。当温度传感器检测到的温度小于温度阈值，且发动机418产生的热量足以将电池加热到预定温度时，三通阀412允许更多的第二液体与第一液体混合以将电池406加热到预定温度，并且三通阀412允许较少的第二液体通过恒温器416。当温度传感器检测到的温度高于温度阈值时，三通阀412禁止第二液体与第一液体混合，并且第二液体通过恒温器416。与布置在乘员舱加热芯414的入口处的三通阀412相比，本实施例的三通阀412 布置在发动机水套的出口处，且三通阀控制器和恒温器控制器之间的耦合机制不同。
在可选实施例中，三通阀位于发动机冷却回路中的恒温器416和发动机冷却回路中的发动机418之间。电池加热回路包括依次连接的冷却器410、第一储液器402、第一泵404和电池406。三通阀412的第一端连接至冷却器410。三通阀412的第二端连接至发动机418。三通阀412的第三端连接到恒温器416。电池加热回路中的冷却器410连接至发动机冷却回路中的第二储液器422。在本实施例中，图7是根据本发明的可选实施例的电动汽车的电池加热装置的示意图四。如图7所示，在电池加热回路中，冷却器410、第一储液器402、第一泵404和电池406依次连接。温度传感器位于第一泵404和电池406之间。三通阀412连接至冷却器410。通常，发动机418产生的热量足以将电池加热至预定温度，因此可以省略高压加热器408，并且三通阀412直接连接至冷却器410。当温度传感器检测到的温度大于温度阈值时，三通阀412允许较少的第二液体与第一液体混合以加热电池。当由温度传感器检测到的温度小于温度阈值时，三通阀412允许更多的第二液体与第一液体混合以加热电池。本实施例取消了高压加热器408，降低了成本，减小了封装空间，并且降低了系统复杂性。
在前述实施例中，使用从发动机冷却回路再循环的精确计量的废热来加热电池，可以提高能量利用效率和等效的燃料经济性，降低了成本，并减小了整个系统的重量和包装空间，使系统更紧凑，更轻便。
