Description

用于混合动力电池热***的加热器和泵性能诊断
技术领域
本发明涉及用于加热或冷却混合动力电池组的热***的泵和加热器的性能诊断。
背景技术
一些车辆至少部分时间使用取自高压直流电(DC)电池组的电能来推进。电池组通过功率变换器给一个或多个多相电牵引马达供给能量。混合动力电动车辆选择地单独或与牵引马达（一个或多个）结合使用内燃发动机，作为变速器的输入扭矩源，而增程型电动车辆仅在需要时使用较小的发动机，并仅用于为发电机提供功率。电池电动车辆先使用小型气体发动机，并且替代地使用存储的电能或再生制动动能量来操作。所有的三种车辆构造都可单独地以电力来操作，该模式被称为电动车辆(EV)模式。
在所有的上述车辆实施例中，高压DC电池组用于交替地存储并传送驱动牵引马达（一个或多个）所需的大量电能。电池组在操作中产生热量，该电池组可包括多个电池模块，多个电池模块每一个容纳多个圆柱状或扁平状/平板状的电池芯。有效地消散产生的热量对优化车辆性能是必要的。因此，热***与电池组结合使用以将一定体积的适当的冷却流体循环通过电池组和任何关联的电力电子装置。
发明内容
本文公开了一种***，包括电池组、热传递流体、加热器、泵以及温度传感器，该泵将流体循环通过加热器至电池组。温度传感器位于流体回路中，例如在加热器和电池组之间或其他地方，并且测量流体的温度。
控制器响应于接收的启动信号(例如在***用作车辆的一部分时为点火信号)来选择性地开启泵，并且之后在泵保持开启时计算流体的温度梯度的绝对值。如果温度梯度的绝对值超出校准的速率，则控制器记录通过泵诊断编码。然后，仅在通过控制逻辑请求加热或计算的温度梯度的绝对值未超过校准的速率时，控制器执行加热器诊断。加热器诊断的执行包括关闭泵；循环开启和关闭加热器，以产生一部分加热的流体；以及监测来自温度传感器的足够的温度上升的温度信号。
本发明还公开了一种用于诊断上述***的方法。该方法包括测量流体的温度，通过控制器接收启动信号，以及响应于接收的启动信号来开启泵。该方法还包括在泵保持开启时使用温度信号计算冷却剂的温度梯度的绝对值，以及然后如果计算的温度梯度的绝对值超过校准的速率时，记录通过泵诊断编码。即，实际的温度梯度可能为负值。在这种情况下，温度梯度必须小于校准的速率。使用绝对值用于所需的比较允许使用单个校准的速率。
另外，该方法包括在计算温度梯度的绝对值之后，仅在请求电池加热或在计算的温度梯度的绝对值未超过校准的速率时，执行加热器诊断，包括关闭泵；循环开启和关闭加热器；以及监测如上面说明的校准的温度升高的温度信号。
当参考附图时，从以下对用于实现本发明的最佳方式的详细描述，本发明的上述特征和优点以及其他特征和优点变得显而易见。
附图说明
图1为具有高压电池组、用于加热或冷却电池组的热***以及诊断热***的泵和加热器性能的控制器的车辆的示意图；
图2为可用在图1示出的车辆上的示例性热***的示意图；
图3为描述用于诊断图2示出的热***的泵和加热器的示例方法的流程图。
具体实施方式
参考附图，示例性车辆10示意性地示出在图1中，该车辆10具有高压电牵引马达12、变速器14以及一组驱动车轮16。车辆10还包括可再充电电池组18，其通过热***20来冷却，下文参考图2更详细地描述该热***20的示例。热***20将热传递流体(箭头22)，例如冷却剂或气体，循环通过电池组18，以在电池组18的操作期间给电池组18提供热量或消散来自电池组18的热量。虽然为了更简明而未在图1中示出，但是同样的热***20还可用于将流体(箭头22)循环通过用于控制牵引马达12的多个电力电子装置，例如牵引功率变换器模块(TPIM)26，辅助功率模块/DC-DC变换器(未示出)等。
控制器30，其功能在下文中参照图3详细描述其功能，通过通信总线15，例如本领域已知类型的控制器局域网(CAN)总线，与热***20的多个部件通信。为了以高能效方式达到车载诊断要求，控制器30执行实现为方法100的指令，以诊断热***20的主要部件的性能，该主要部件包括如图2所示的加热器28和泵50。通过提供图2的泵50的诊断，而无需以传统方式始终使用加热器28，本诊断方法可预期用作传统诊断方法的高能效替代方式。因此，本方法的使用可提供一定的能量节省，同时还降低对加热器28的不必要使用。
图1中所示的车辆10可包括可任选的内燃发动机24，如虚线所示，例如当车辆10配置为混合动力电动车辆或增程型电动车辆，而非电池电动车辆时。在一个可能的实施例中，发动机24可通过输入阻尼离合器11连接至牵引马达12的输入端。来自发动机24的扭矩可用于在需要时直接或通过产生电来给牵引马达12提供功率。在另一构造中，发动机24可替代地连接至变速器14，以将输入扭矩直接传送至变速器14。
本文描述的热***20和附随的方法100可与任何使用诸如热***20的热***的高压电池组18一起使用，用于加热和冷却。虽然车辆推进为电池组18和牵引电动机12的适当的应用，但是本方法可用于使用与图1所示的电池组18相似的电池的非车辆应用中，而不偏离预期的发明范围。因此，图1示出的构造旨在为说明性的，而非限制性的示例实施例。
图1所示的示例性牵引马达12从电池组18提取电能和将电能传送至电池组18。因此，电池组18形成可再充电的能量存储***，用于给在车辆10上使用的所有高压电组件提供能量。如本文中所用的，术语“高压”指的是超过通常用于给辅助车辆***提供功率的任何辅助/12V DC电压水平的电压水平，该辅助车辆***例如为音频***、照明设备等。根据牵引马达12的额定功率，电池组18可额定为大约60VDC至300VDC之上。其他的电池设计可在较低的额定电压下使用。然而，对专用流体冷却回路的需求随着减少的电压输出而减少，并且因此其余的示例将返回参照图1示出的高压部件。
当牵引马达12配置为多相交流电(AC)感应式电机时，车辆10可还包括上述的TPIM26。TPIM26通过高压DC总线17电连接至电池组18，并且通过高压AC总线13电连接至牵引马达12。如本领域众所周知的，可通过脉宽调制和高速半导体开关来控制TPIM26，以将由牵引马达12产生的AC功率转变为适合用于存储在电池组18中的DC功率，以及根据需要将存储的DC功率转变回AC功率，以给牵引马达12提供功率。这种功能产生大量的热量，并因此需要通过热***20的流体冷却。同样地，当电池组18用在寒冷天气时，开关部件和其他电气装置的性能会变差，因此热***20可根据需要用于加热电池组18。
图1所示的控制器30使用接收的温度信号(箭头160、162)，执行来自有形的、非暂时性存储器装置36的实现为本方法100的指令或编码，该温度信号的来源将参考图2在下文中说明。方法100的执行允许控制器30的处理器34诊断热力***20的性能。可将控制器30配置为数字计算机，其如存储器装置36一样，具有只读存储器(ROM)、闪存及/或其他的磁性或光学存储介质。
控制器30还包括足够的随机存取存储器(RAM)、电可擦除可编程只读存储器(EEPROM)等。此外，控制器30可包括高速时钟、模拟-数字(A/D)和数字-模拟(D/A)电路和输入/输出电路和装置(I/O)，以及合适的信号调节和缓冲电路，以提供全功能硬件和软件控制装置。
在示例实施例中，加热控制信号(箭头161)可由控制器30产生或接收，以确定何时需要热***20的电池加热。亦即，电池加热是由考虑若干参数的控制逻辑导致的，该若干参数例如为电池温度、冷却剂温度、环境温度、电池充电状态(SOC)、诸如充电、驾驶等的车辆操作模式以及车辆故障信息，所述车辆故障信息例如为如果入口传感器60(见图2)损坏，则没有通过控制信号(箭头161)来请求加热。
参考图2，控制器30最终响应加热器28和泵50的诊断而执行适当的控制行为。作为该控制行为的一部分，控制器30可分别以具有相应的通过或故障状态的每一个诊断编码，输出用于加热器28和泵50的诊断编码(箭头55和57)。其他的控制行为可包括使警示灯发光、将编码传输至远程位置或便携式装置、修理和更换加热器28和泵50等。
图2所示的热***20包括流体导管25、125(例如几节管子、管状物和/或液压/气动软管)和任何必需的配件。热***20的引擎盖下部件包括在假想的分割线52的第一侧(箭头54)。线52的另一侧由箭头56指示，并且表示通过本方法评估的热***20的电池冷却元件。
在电池冷却剂一侧(箭头56)，电池组18接收流体导管25，并内部地引导流体导管25接近热量产生元件，例如导热电池芯(未示出)。通过由泵50产生的吸力，使流体(箭头22)运动至电池组18中。最终，通过控制器30或通过其他合适的控制装置，使用传输至泵50的速度信号(箭头72)来控制泵50的速度。
图2的加热器28大致位于电池组18的上游。诸如热电偶的温度传感器60位于加热器28的下游，在电池组18的流体入口处或其附近。相似的传感器62可位于电池组18的出口处，并且例如用于评估在电池组18上发生的实际冷却。在执行本方法100期间，来自各个温度传感器60、62的温度信号(箭头160、162)通过图1的通信总线15或以无线方式被馈送到控制器30，该方法的示例被示于图3中并在下文中被描述。
仍然参考图2，引擎盖下的一侧，即由箭头54表示的一侧可包括本领域中已知类型的散热器40和冷凝器42。在流体导管25内的流体流(箭头43)最终经过节点81，在该处，多个流体流(箭头43)合并为单个流，以限定最终被抽吸入泵50的流体的流（箭头22）。四通冷却剂模式阀82可用于将在热***20中使用的流体(箭头22)的一些转移至冷却器46，如图所示。例如，阀82可分流流体流(箭头22)，使得流(箭头47)进入冷却器46，流(箭头43)进入散热器40，以及流(箭头45)到达节点81。冷却器46可为具有空调压缩机48的空调***的一部分，空调压缩机48的功能通过空调控制模块49来控制，或者可任选地，在控制器30包括这种功能时，通过信号(箭头70)来控制。
图2所示的空调压缩机48将制冷剂流(箭头41)传送至冷凝器42，并且通过热膨胀阀80最终至冷却器46。相似的热膨胀阀180可与蒸发器44结合使用。图2的热***的所有部件示意地示于图2中。如本领域普通技术人员所知的，热***20可包括附加的流体控制部件及传感器，以完全实现具有期望功能的空调***。然而，为了根据下文中描述的方法100而适当地运行，热***20的所有实施例必须至少包括泵50和加热器28，即用于将流体(箭头22)循环至电池组18的流动装置以及配置为根据需要提高流体(箭头22)的温度的加热装置。
参考图3，显示了用于甚至在不需要操作加热器28时，仍能诊断泵50的性能的示例性方法100，与传统的需要加热器28同时操作来评估泵50的传统方法不同。在执行方法100时，控制器30利用适当的条件，以节省能量及降低加热器28的不必要的循环。
以步骤102开始，图1和2的控制器30首先检测启动信号(例如点火事件，车辆在点火事件之后运行)，然后，行进到步骤104。因此，步骤102是执行方法100的其余部分的前提。
在步骤104处，一旦在步骤102处启动了方法100的执行，则控制器30开启图2所示的泵50。泵50开始将流体(箭头22)循环通过电池组18。在流体(箭头22)继续流动时，方法100行进到步骤106。
在步骤106处，控制器30接下来接收来自温度传感器60，或者替代地来自位于流体流(箭头22)中的任何其他温度传感器的温度信号(箭头160)，然后计算流体(箭头22)的温度梯度的绝对值。比较计算的温度梯度的绝对值和校准的速率。如果温度梯度的绝对值超过校准的速率，即流体22的温度升高或下降比不存在流体流（箭头22）自然发生的更快，则方法100行进到步骤108。否则，方法100行进到步骤110。
在步骤108处，控制器30记录用于泵50的指示泵50正常运转的状态的诊断编码(图2的箭头57)。然后，方法100行进到步骤112。
在步骤110处，控制器30接下来运行加热器诊断。例如，控制器30可关闭泵50，并且开启加热器28。加热器28在校准过程中保持开启，之后，控制器30再次将加热器28返回到关闭。通过该步骤，产生一部分加热的流体(箭头22)。然后，方法100行进到步骤114。
在步骤112，控制器30确定是否已经通过图1中的控制信号(箭头161)请求电池加热。步骤112中使用的控制信号(箭头161)可自动产生，例如在电池组18的外部温度或内部温度下降低于校准的最小阈值时。如果没有请求加热，则方法100行进到步骤122。否则，方法100行进到步骤110。
在步骤114处，由于步骤112，图2和3所示的控制器30应该察觉到电池组18的入口温度的上升，如通过温度传感器60所测量的。按照该假设，控制器30比较入口温度(箭头160)与预期的温度上升，并且如果检测到预期的温度上升时，则行进到步骤116。否则，方法100行进到步骤118。
在步骤116处，已经在步骤114处检测到温度的预期上升的控制器30运行泵50的随后诊断。步骤116可能将泵50返回到开启，这是将导致由温度传感器60测量的进入图1和2的电池组18的流体(箭头22)的温度降低的控制行为。方法100行进到步骤120。如果该标准在步骤106中没有达到，则步骤116的执行可提供泵50的第二诊断。因此，可一直评估泵50，但是与传统方法不同，加热器仅在响应步骤106的负结果或在步骤112处的加热请求时进行评估。
在步骤118处，控制器30将用于加热器28的故障诊断编码记录在存储器装置36中。作为步骤118的结果，可采取随后的控制行为，其包括加热器28的修理或更换和/或警示灯发光。
在步骤120处，根据步骤116的结果，控制器30接下来记录泵50的通过或发生故障的诊断编码。亦即，如果发生由温度传感器60测量的预期的温度降低，则控制器30以相应的通过状态将诊断编码记录在存储器装置36中。然而，如果预期的温度降低未在校准窗口内实现，则这表示泵50的不期望的缓慢性能或故障。在该情况中，控制器30以相应的故障状态记录诊断编码。与步骤118一样，由于发生故障的泵诊断编码，可采取任何适当的控制行为，包括泵50的修理或更换，警示灯发光等。
在步骤122处，控制器30通过记录指示未完成加热器28的评估的诊断编码来完成方法100。亦即，在步骤108处成功评估泵50之后，到达步骤112。因为在步骤112处未请求加热，因此未在本诊断循环中执行步骤110的加热器诊断。
因此，上述方法110的执行导致四种可能的诊断结果：发生故障的加热器28，与泵50的性能无关；通过的泵50和通过的加热器28；通过的泵50，未诊断加热器28；以及，发生故障的泵50和通过的加热器。本方法通过将电能的不必要使用和高压部件的过度循环最小化，以相对能效高的方式满足了车载诊断(OBD)要求。
虽然已经详细描述了用于实现本发明的最佳方式，但是熟悉本发明涉及领域的人员将认识到在所附权利要求的范围内的用于实践本发明的多种替代设计和实施例。
