Description

用于控制充电系统的方法以及充电系统 技术领域
本公开主要涉及充电技术领域，更具体地，涉及用于控制充电系统的方法以及相应的充电系统。
背景技术
为了减少碳排放以及应对大气污染等问题，在一些国家和地区中日益普及诸如电动车辆的新能源车辆，以替代传统的燃油车辆。电动车辆需要在充电站或其他充电场所中利用充电系统进行充电，从而满足其动力需求。在电动车辆的充电过程中，非常容易发生安全事故。调查表明，在众多已经发生的电动车辆自燃事故中，充电过程中发生的事故占比最高。
影响车辆充电安全的因素很多。例如，在交流充电设备中，存在剩余电流保护功能不符合国标要求、无输出过载保护等问题；在直流充电设备中，存在设备响应需求不及时、通信协议一致性差、互操作不达标、诸如电子锁之类的充电接口结构不符合国标要求等问题；这些问题降低了交直流充电设备的一次充电成功率并增加了安全隐患。此外，从车辆驶入充电场所开始充电直到充电完成的整个过程中，很多环节都可能存在安全隐患。然而，由于充电过程中缺乏安全管理、或者由于管理人员或操作人员的疏忽，一些安全隐患会因没有及时干预而很快发展成为充电安全事故，从而造成人员和财产损失。
目前，缺乏有效的手段来自动或实时地对充电安全进行管理。特别是，随着充电技术和电池技术的不断发展，越来越多的充电系统可以采用大功率快充模式，例如低压大电流和高压低电流技术，而充电过程中的大功率进一步使充电安全问题更加突出，例如大功率的电流可能在充电线路或端口处引起过温，从而导致火灾。

应当理解，发明内容部分中所描述的内容并非旨在限定本公开的实施例的关键或重要特征，亦非用于限制本公开的范围。本公开的其它特征将通过以下的描述变得容易理解。

结合附图并参考以下详细说明，本公开各实施例的上述和其他特征、优点及方面将变得更加明显。在附图中，相同或相似的附图标注表示相同或相似的元素，其中：

具体实施方式
下面将参照附图更详细地描述本公开的实施例。虽然附图中显示了本公开的某些实施例，然而应当理解的是，本公开可以通过各种形式来实现，而且不应该被解释为限于这里阐述的实施例，相反提供这些实施例是为了更加透彻和完整地理解本公开。应当理解的是，本公开的附图及实施例仅用于示例性作用，并非用于限制本公开的保护范围。
在本公开的实施例的描述中，术语“包括”及其类似用语应当理解为开放性包含，即“包括但不限于”。术语“基于”应当理解为“至少部分地基于”。术语“一个实施例”或“该实施例”应当理解为“至少一个实施例”。术语“第一”、“第二”等等可以指代不同的或相同的对象。下文还可能包括其他明确的和隐含的定义。
如上文所述，在车辆充电过程中存在容易引发事故的诸多安全隐患，例如充电线路或端口处的过温问题。在常规解决方案，会在充电枪上设置温度传感器，同时对充电系统的输出断路器上的电压和电流进行检测，从而防止由于温度过高而引发事故。但是，这种方式可靠性较差，并不能有效消除隐患。例如，当充电枪插在电动车辆的充电端口上对车辆进行充电时，两者之间通过公母端子接触进行电能传输，并通过信号线(例如PE信号线)进行通信信号传输；然而，由于某些原因，例如充电枪没有完全插入到位或充电枪/电动车辆的充电端口存在磨损，可能导致接触不良，信号传输会出现异常，这进而导致无法获知过温状况，从而引发火灾事故。
针对上述以及其他潜在的问题，本公开的实施例提供了控制充电系统的方案。根据本公开的实施例，可以在充电系统中设置光感测设备，并且充电系统的控制器可以获取光感测设备所感测的信息，从而自动检测或标识车辆充电时可能出现的危险状况。在出现危险状况时，充电系统可以立即改变充电功率或者向操作人员发出提醒，由此可以及时消除车辆充电过程中可能出现的安全隐患，以避免引发事故，从而有效和可靠地实现车辆的充电安全管理。

充电系统10可以包括充电桩11。充电桩11设置有作为充电接口的充电枪和充电线缆，并且可以电连接到车辆30的充电端口来为车辆30充电。图1中所示的充电桩11为落地式充电桩，并且具有一个充电接口。但是，充电桩11的类型并不受限于此，而可以是挂壁式充电桩或其他类型的充电桩，并且充电桩11可以包括任何数目的充电接口。此外，充电桩11例如还可以包括人机交互界面、计量装置、过电压保护装置、过电流保护装置、漏电保护装置等。
充电系统10可以包括功率转换设备12和控制器13。功率转换设备12连接到充电桩11和诸如公用电网之类的电源，以使来自电源的电能经由功率转换设备12输送到充电桩14，进而提供给需要充电的车辆30。控制器13可以以有线和/或无线的方式通信连接到功率转换设备12，以对功率转换设备12的功率输出进行控制。此外，控制器13还可以以有线和/或无线的方式连接到远端的计算机或服务器80(例如可以位于充电站的控制中心)以提供状态信息或接收控制指令，并且控制器13还可以进一步通过计算机或服务器80连接到互联网或云端90。备选地，控制器13可以以有线和/或无线的方式通信连接到车辆30，例如通过控制器局域网络(Controller Area Network,CAN)、4G、WiFi和蓝牙等方式连接车辆30，以与车辆30进行信息交互。
作为示例，功率转换设备12可以包括多个充电模块以及智能断路器矩阵。每个充电模块可以包括能够实现诸如整流、DC-DC转换之类的功率转换功能的转换器，并且输出固定范围的功率。每个充电模块与充电桩11的连接取决于智能断路器矩阵中的对应断路器的通断。控制器13可以向功率转换设备12输出控制信号以对智能断路器矩阵中的各个断路器的通断进行控制，从而将所需数目的充电模块连接到充电桩11，并且控制器13也可以控制每个充电模块的功率输出。由此，控制器13可以实现对功率转换设备12的功率输出的调节和控制。
充电系统10可以还包括光感测设备14。光感测设备14可以面对充电区域20和位于充电区域20中的车辆30，以接收来自充电区域20和车辆30的光，从而可以获取位于充电区域20中的车辆30的充电状况的信息。作为示例，光感测设备14可以包括红外传感器或可见光传感器，或者可以包括红外传感器和可见光传感器两者，或者可以是集成了红外感测功能和可见光感测功能的设备。例如，光感测设备14可以是可见光相机、红外相机或集成相机，并且具有广角拍摄功能，以至少覆盖充电区域20。如图1所示，光感测设备14可以安装在充电桩11上。然而，光感测设备14的安装位置并不受限于此，而是可以安装在能够接收来自充电区域20和车辆30的光的任何适当位置。光感测设备14可以以有线和/或无线的方式通信连接到控制器13，以便将感测信息传输给控制器13。由此，控制器13可以根据这些感测信息来对功率转换设备12进行控制。
要注意的是，图1所示出的充电系统10仅仅是示意性的，其可以以多种形式来实现。例如，充电系统10可以包括充电终端和充电机，并且充电桩11和光感测设备14可以位于充电终端一侧，而功率转换设备12可以位于充电机一侧。此外，作为示例，图2示出了根据本公开的一个实施例的充电系统10的部分设备的示意性框图。如图2所示，控制器13例如可以 由控制主机131和近端芯片132组成，并且控制主机131可以位于充电机一侧，而近端芯片132可以位于充电终端一侧，例如与光感测设备14集成在一起。近端芯片132可以包括本地存储芯片、图像或视频处理芯片、以及图像或视频传输芯片。近端芯片132可以对光感测设备14的感测信息进行本地预处理，并且将预处理后的信息传输给控制主机131。可以看出，通过本地预处理的方式，可以减少传输造成的时延，从而更快处理光感测设备14的感测信息，同时也大大减少充电机一侧的控制器的工作量。
然而，可以理解的是，控制器13的实现方式并不受限与此，而是也可以以单个控制器或芯片、或者更多控制器或芯片的形式来实现。此外，除了充电终端和充电机的形式，充电系统10也可以以一个整体来形成，即功率转换设备12、控制器13和充电桩14可以都被设置在整体设备中，而不再区分充电终端和充电机。作为备选，充电桩11、功率转换设备12、控制器13和光感测设备14也可以均分别被单独设置，或者可以部分地被集成在一起。
图3示出了本公开的一些实施例可以在其中实施的另一示例充电场景100’的示意图。与图1的不同之处在于，在充电场景100’中，充电系统10可以包括多个充电桩11-1、11-2……11-n。相应地，在多个充电桩11-1、11-2……11-n附近分别设置有多个充电区域20-1、20-2……20-n，以供多个车辆(例如车辆30-1和30-2)停放和充电。充电系统10还可以包括多个光感测设备14-1、14-2……14-n，以面对各个充电区域20-1、20-2……20-n和位于各个充电区域中的车辆。与图1的描述相同，多个光感测设备14-1、14-2……14-n可以分别安装在各个充电桩11-1、11-2……11-n上，也可以安装在任何其他适当位置。
此外，充电系统100同样具有功率转换设备12和控制器13。功率转换设备12可以向多个充电桩11-1、11-2……11-n输出功率，而控制器13可以耦合到多个光感测设备14-1、14-2……14-n，并且根据来自这些光感测设备的感测信息来对功率转换设备12进行控制。可以理解的是，功率转换设备12和控制器13可以以任何适当的方式基于多个光感测设备14-1、14-2……14-n来控制输出到多个充电桩11-1、11-2……11-n的功率。例如，功率转换设备12可以改变输出的总功率，也可以改变输出到单个充电桩(例如11-1)的功率。例如，控制器13可以接收一个或多个光感测设备的信息，并根据来自各个光感测设备的感测信息，来控制输出到对应充电桩或对应充电区域中的车辆的功率，例如控制器13可以根据光感测设备14-1的感测信息，来控制功率转换设备12，以改变输出到充电桩11-1或充电区域20-1中的车辆的充电功率。备选地，控制器13可以根据某个光感测设备的感测信息，针对非对应的充电桩或充电区域的车辆的充电功率进行控制，例如，控制器13可以根据光感测设备14-1的感测信息，来改变输出到充电桩11-2或充电区域20-2中的车辆的充电功率。备选地，控制器13可以接收多个光感测设备的感测信息，并对这些感测信息进行综合处理，来改变一个或多个充电区域的车辆的充电功率，例如控制器13可以根据光感测设备与一个或多个充电区域的相关性，来对各个光感测设备的感测信息进行加权处理。
图4示出了根据本公开的实施例的控制充电系统10的方法400的示意流程框图。方法400可以在图1和图3的充电场景100和100’中实现，并且可以由充电系统10的控制器13或者其他适当的设备来执行。可以理解，上面关于图1至图3所描述的各个方面，可以适用于方法400。为了讨论的目的，将结合图1至图3来描述方法400。
在框401处，控制器13从光感测设备14获取与车辆30的充电状况有关的感测信息。具体而言，在充电系统10对充电区域20中的车辆30进行充电期间，由于光感测设备14面对正在充电的车辆30，因此光感测设备14的感测区域覆盖了车辆30和充电系统10中的与充 电有关的部件，从而可以获取与车辆30的充电状况有关的感测信息，这些感测信息反映了车辆30在充电过程中是否存在安全隐患。
在本公开的某些实施例中，控制器13可以从光感测设备14获取与车辆30的充电状况有关的红外感测信息和可见光感测信息中的至少一种信息。作为示例，光感测设备14可以包括红外传感器和/或可见光传感器，例如可以是具有红外摄像和可见光摄像功能的集成相机。在充电过程中，功率传输会引起充电系统10和车辆30中的一些部件发热，并因此向外辐射红外光或红外线。通过光感测设备14所获取的红外感测信息，控制器13可以确定这些发热部件的温度，并判断在充电过程中是否存在过高温度。此外，在夜晚并且缺乏照明的情况下，红外感测信息可以帮助控制器13获得红外图像，这例如可以指示充电系统10的一些部件(例如充电枪)和车辆30的位置，从而帮助控制器13确定是否发生危险事件。另一方面，在白天或者在存在照明的情况下，光感测设备14可以获取感测区域内的车辆30和充电系统10的部件所反射的可见光。控制器13根据这些感测信息，可以直接获得可见光图像，并由此判断是否出现危险事件。
在框402处，控制器13基于所获取的感测信息，标识影响车辆30的充电安全的事件。具体而言，控制器13可以利用来自光感测设备14的感测信息来自动且实时地判断是否存在危险事件，这种危险事件可能会在充电期间引发安全事故。
在框403处，控制器13基于所标识的事件，输出预警信号和控制信号中的至少一种，预警信号用于警示充电操作人员或用于记录所述事件，控制信号用于改变从充电系统10到车辆30的功率输出。具体而言，在标识出影响充电安全的事件之后，控制器13可以根据事件的具体情况，来确定采取什么措施。例如，控制器13可以发出警示操作人员的音频警报或视频警报，或者仅记录该事件，以供操作人员在需要时进行查阅。控制器13还可以直接向功率转换设备12发出控制信号，以改变输出到充电桩11的功率，即改变输出到充电区域20中的车辆30的功率。
例如，控制器13可以从车辆和充电数据库(例如位于充电系统10的充电机一侧)中获取充电枪的阈值温度T max，并且控制器13在接收到指示充电温度(例如充电枪的温度)的感测信息之后，可以将充电枪的当前温度与阈值温度T max进行比较。如果充电枪的温度超过阈值温度T max，并且持续时间超过预定时间，则可以向功率转换设备12发出控制信号，从而降低车辆30的充电功率。在降低充电功率之后，如果充电枪的温度仍然高于阈值温度T max达预定时间，则继续降低充电功率，并重复执行上述操作，直至将车辆30的充电功率降低为零。
需要说明的是，虽然目前的一些充电场所配备有安防摄像头，以用于对充电场所的整体环境进行监控，但是在这些充电场所中，摄像头与充电系统和车辆之间均没有通信和配合，因此在充电过程中需要操作人员主动处理和排除安全隐患，这种安全管理具有较差的可靠性。此外，如前文所述，对于过温问题，常规方案仍然依赖于位于充电枪上的温度传感器的检测，其可靠性较差。与此不同，在本公开的实施例中，通过光感测设备14、控制器13和功率转换设备12之间的信息交互和协同配合，可以智能和实时地管理车辆充电过程中的充电安全，例如可以利用人工智能+(Artificial Intelligence Plus,AI+)的智能视频方式，来解决车辆的充电安全问题，并且不再需要在充电枪或充电线缆上设置温度传感器。相比于常规方案，这种方式能够更有效地消除车辆充电过程中的所有环节的安全隐患。
图5示出了标识影响车辆的充电安全的事件的方法500的示意性框图。以下继续结合在图1和图3的充电场景100和100’来描述方法500。
在充电系统10向车辆30充电的过程中，充电连接位置作为功率传输路径上的连接节点可能会存在严重的发热，其温度可以有效指示当前的充电线路是否存在可能引发事故的过高温度。对此，在框501，控制器13基于所获取的红外感测信息，确定充电系统10与车辆30之间的充电连接位置处的温度。在框502，控制器13基于所确定的温度，标识影响车辆30的充电安全的事件。
以此方式，可以基于红外感测信息来确定充电连接位置的温度，并且判断当前的充电是否安全。相比于在充电枪上设置温度传感器的方式，图5所示的实施例所采用的这种方式更加高效和可靠。
图6示出了标识影响车辆的充电安全的事件的方法600的示意性框图，该方法600继续通过结合在图1和图3的充电场景100和100’来进行描述。
在框601，控制器13基于所获取的红外感测信息，确定充电系统10与车辆30之间的充电连接位置处的温度在阈值温度以上的持续时间。在框602，控制器13判断持续时间是否超过预定时间长度。在框603，控制器13基于所确定的持续时间超过预定时间长度，标识影响车辆30的充电安全的事件。具体而言，控制器13可以持续监测充电连接位置的温度过高的持续时间，并且仅在过高温度持续足够长时间的情况下，确定存在影响充电安全的危险事件。以此方式，可以有效避免误判，同时提高标识的准确度。
在本公开的某些实施例中，充电连接位置处的温度包括以下各项中的至少一项：充电系统10的充电枪的温度、充电系统10的充电线缆的温度、以及车辆30的充电端口的温度。作为示例，充电系统10的充电枪和充电线缆、以及车辆30的充电端口在接触不良或者其他充电异常的情况下易于发生过温，这种过温在严重时可能导致火灾等严重事故。因此，通过检测这些位置的温度，能够有效地确定当前充电是否正常，并且不再需要在充电枪上设置温度传感器。
在本公开的某些实施例中，控制器13还可以基于所获取的感测信息，来识别影响车辆30的充电安全的行为，以及基于所识别的行为，标识影响车辆30的充电安全的事件。作为示例，控制器13可以通过可见光感测信息和/或红外感测信息来获得可见光图像和/或红外图像，并且例如通过图像识别，可以确定车辆30的充电过程中是否存在危险行为，这些危险行为可能会引发事故。
在本公开的某些实施例中，影响车辆30的充电安全的行为包括以下各项中的至少一项：充电系统10的用于车辆30的充电枪的移位、车辆30的移动、以及异物靠近充电枪。具体而言，在车辆30的充电期间，如果作为充电对象的车辆30发生移动或者插入车辆30的充电端口的充电枪发生移位，将会导致充电异常，例如导致电接触不良，甚至引起电弧。此外，诸如金属、动物之类的异物靠近充电枪也可能影响充电安全，进而引发事故。因此，通过识别这些行为，有助于确定造成安全隐患的事件。
图7示出了输出预警信号和/或控制信号的方法700的示意性框图，该方法700继续通过结合在图1和图3的充电场景100和100’来进行描述。。
在框701，控制器13基于所标识的事件，确定事件的风险级别。在框702，控制器13确定风险级别是否为高风险级别。在框703，如果风险级别为高风险级别，则控制器13输出用于停止功率输出的控制信号。在框704，如果控制器13确定风险级别不是高风险级别，则确定风险级别是否是中风险级别。在框705，如果风险级别为中风险级别，则控制器13输出用于减少功率输出的控制信号。在框706，如果控制器13确定风险级别不是中风险级别，则确 定风险级别是否是低风险级别。在框707，如果风险级别为低风险级别，则控制器13输出预警信号。
此外，如果事件没有被归入高、中、低风险级别，则控制器13可以继续接收和处理感测信息以保持监控，或者可以将事件以适当的方式提示操作人员，以便由操作人员来判断是否需要针对事件采取措施。可以理解的是，三个风险级别的判断顺序仅仅是示例性，而非限制性的，因此也可以以其他的顺序或者以并行处理的方式来完成上述判断步骤，例如也可以先判断是否是低风险级别。通过设置风险级别，可以对不同风险级别的事件进行不同的处理，这可以在保证充电安全的情况下，尽可能使充电保持较高效率，从而以更加精细的方式管理车辆的充电安全。仅仅作为示例，以下通过表1示意性示出了各类事件的风险级别以及相应的措施。
表1风险级别以及相应的措施
Figure PCTCN2022119389-appb-000001
例如，表1所示出的事件、风险级别和保护措施的对应关系可以预先保存在车辆和充电数据库，并且控制器13可以在需要时访问车辆和充电数据库，以根据所标识的事件来确定风险级别和采取的具体措施。作为示例，如前文所示，在图2所示的控制器13中，作为本地控制器部分的近端芯片132例如位于充电终端一侧，其可以是本地AI芯片或可以将数据上传云端处理。近端芯片132可以实时对光感测设备14所传递的感测信息进行处理，并且判断是否存在异常。在异常的情况下，近端芯片132可以访问车辆和充电数据库以确定风险级别和相应措施，并向控制主机131(例如位于充电机一侧)发出信息，以便控制主机131控制功率转换设备12或发出预警信号，或者近端芯片132也可以直接向控制主机131发出信息，并且由控制主机131访问车辆和充电数据库来确定风险级别和相应措施，并进一步控制功率转换设备12或发出预警信号。
图8示出了根据本公开的另一实施例的方法800的示意性框图。在框801处，在充电系统10对车辆30进行充电之前，控制器13基于从光感测设备14获取的针对充电区域20的感测信息，确定车辆30正在进入充电区域20。在框802，控制器13判断正在进入充电区域的车辆30是否与目标车辆匹配。在框803处，如果确定车辆30与目标车辆匹配，则控制器13输出落锁信号，落锁信号用于使充电区域20中的车位锁落锁。作为示例，在家用充电场景下，利用光感测设备14的感测信息，控制器13可以确定正在试图进入充电区域20的车辆30是 否是家庭车辆。在确定之后，控制器13可以预先与充电桩11进行信息对接，并且解锁充电区域20中的车位锁，以实现自动落锁。在确认车辆30停车到位之后，控制器13还可以自动启动充电桩11与车辆30的信息对接，以提前匹配功率及充电服务，实现即插即充，改善家用充电场景下的用户体验。
图9示出了根据本公开的又一实施例的方法900的示意性框图。以下继续结合在图1和图3的充电场景100和100’来描述方法900。
在框901，在充电系统10对车辆30进行充电之前，控制器13从光感测设备14获取车辆30的感测信息。在框902，基于车辆30的感测信息，控制器13标识车辆30的车型。在框903，基于所标识的车型，控制器13确定车辆30的充电曲线。在框904，在充电系统10连接到车辆30时，控制器13基于所确定的充电曲线和从车辆30获取的电池状态信息，输出用于控制功率输出的初始控制信号。
作为示例，在车辆30驶入充电区域20时，借助于光感测设备14感测的信息，控制器13可以获取车辆外形信息，并访问车辆数据库以确定车辆30的车型以及与车型对应的充电曲线。在一个实施例中，控制器13的近端芯片132可以将车辆外形信息传送给控制主机131，控制主机131然后可以访问车辆数据库来确定车辆30的车型以及该车型的充电曲线。在一个实施例中，控制器13还可以确定车辆30的车牌等信息。然后，在车辆30的驾驶员将充电枪插入车辆30的充电端口之后，车辆30的通信装置与充电系统10的通信装置进行握手，并完成信息交换和检测。在完成确认后，充电系统10连接高压电并准备按充电程序进行充电，并且控制器13根据从车辆30一侧上传的信息，读取车辆30的荷电状态(State of Charge,SOC)及充电电压和电流值。根据SOC值和该车辆的充电曲线，控制器13可以控制功率转换设备12向充电车辆输出所需的充电功率，例如可以控制智能断路器矩阵以分配充电模块，而未被分配的其他充电模块被断开连接并休眠。通过这种方式，充电系统10可以预先获知待充电车辆的需求，并按照车辆所需的充电配置对车辆进行充电，从而提高了充电效率。
在根据本公开的实施例的充电系统以及控制充电系统的方法中，可以利用光感测设备和控制器的配合来自动检测或标识车辆充电时可能出现的危险状况，并且在出现危险状况时控制功率转换设备立即改变充电功率或者向操作人员发出提醒。由此，可以消除车辆充电过程的各个环节中可能出现的安全隐患，从而有效避免事故的发生。
图10示出了根据本公开的实施例的控制充电系统的装置1000的示意性框图。以下继续结合在图1和图3的充电场景100和100’来描述装置1000。装置1000包括：获取模块1001，被配置为从光感测设备14获取与车辆30的充电状况有关的感测信息；标识模块1002，被配置为基于所获取的感测信息，标识影响车辆30的充电安全的事件；以及输出模块1003，被配置为输出预警信号和控制信号中的至少一种，预警信号用于警示充电操作人员或用于记录事件，控制信号用于改变从充电系统10到车辆30的功率输出。
