具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、装置、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如图1所示为本申请实施例一种电动车辆充电装置的故障反馈方法实施系统示意图，包括：充电桩101、电动车辆102，其中电动车辆102包括充电装置1021、控制器1022和电池1023。当为电动车辆102充电时，将充电桩101的充电枪插入电动车辆102的充电装置1021中，充电装置1021获取充电桩101的充电枪的类型以及充电电压，并将充电枪类型和充电电压通过通信总线发送给控制器1022，控制器1022根据充电枪的类型、充电电压以及电池1023的剩余电量等生成充电策略并根据一定的发送频率将充电策略发送给充电装置1021，充电装置1021根据充电策略控制开关的闭合，将充电桩101的电量充入电动车辆102的电池1023中，进而对电动车辆102进行充电。此外，充电装置1021在根据充电策略控制开关的闭合之后还获取开关的状态，并以相同的发送频率将开关状态发送给控制器1022，实现控制器1022对充电过程的闭环控制。在本申请实施例中，电动车辆102为电动汽车，也可以是其他类型的电动车辆，例如电动自行车等，本说明书实施例并不限制电动车辆的类型。
为了减小电动车辆102通信总线的压力，通常对消息类型和消息发送的频率进行限制，而当充电装置1021故障时，由于消息类型和消息发送频率的限制，控制器1022不能及时获取到充电装置1021的故障信息，进而不能及时调整充电策略对充电装置1021的开关状态进行控制，充电桩101持续通过故障的充电装置1021对电动车辆102进行充电，增加了充电安全隐患。
本申请实施例所述的一种电动车辆充电装置的故障反馈方法、装置及设备可以应用于充电装置1021中，解决现有技术中充电装置1021故障时，控制器1022不能及时获取到充电装置1021的故障信息，增加了充电的安全隐患的问题。
具体地，本申请实施例提供了一种电动车辆充电装置的故障反馈方法，能够提高充电装置信息的发送速度，降低充电的安全隐患。图2所示为本申请实施例一种电动车辆充电装置的故障反馈方法的流程图。在本图中描述了电动车辆充电装置的故障反馈的过程，但基于常规或者无创造性的劳动可以包括更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式，不代表唯一的执行顺序。在实际中的系统或装置产品执行时，可以按照实施例或者附图所示的方法顺序执行或者并行执行。具体的如图2所示，所述方法可以包括：
步骤201：获取电动车辆充电装置的充电装置信息；
步骤202：根据充电装置信息确定充电装置的故障信息；
步骤203：根据故障信息以及充电装置信息的原通信频率获取高于原通信频率的调整频率，其中，充电装置信息的原通信频率由电动车辆控制器设定；
步骤204：根据调整频率向电动车辆控制器发送充电装置信息，以使电动车辆控制器根据充电装置信息确定充电装置的故障。
通过本申请实施例的方法，电动车辆通过原通信频率与电动车辆控制器进行通信，当电动车辆的充电装置发生故障时，根据故障信息和原通信频率获取高于原通信频率的调整频率，根据调整频率向电动车辆控制器发送充电装置信息，提高了充电装置信息的发送速度，使得电动车辆控制器快速获取到充电装置发生故障时的充电装置信息，以使电动车辆控制器根据充电装置信息快速确定并处理故障，降低充电的安全隐患。
在本申请实施例中，电动车辆的充电装置在正常工作时，充电装置和控制器需要持续通信，充电装置通过一定的频率将充电装置信息发送给控制器，以使控制器根据充电装置信息指导充电。当充电装置发生故障时，通过故障信息和充电装置信息的原通信频率获取高于原通信频率的调整频率，通过调整频率将充电装置信息发送给控制器，控制器可以更快的接收到充电装置信息，并根据充电装置信息确定充电装置的故障。
根据本申请的一个实施例，步骤202中根据充电装置信息确定充电装置的故障信息包括故障类型。
在本申请实施例中，可以对充电装置信息和预设的故障特征进行比较确定故障类型，其中充电装置信息可以包括多种信息类型，因此可以根据充电装置信息确定多种故障类型。
根据本申请的一个实施例，为了提高充电装置信息的发送速度并保证电动车辆其他模块的正常工作，步骤203获取调整频率的过程进一步包括，在预设的频率表中查找与原通信频率和故障类型两者对应的频率值，将查找到的频率值作为调整频率。
在本申请实施例中，预设的频率表可以将原通信频率和故障类型作为索引，得到指定原通信频率和故障类型对应的频率值，其中频率值的大小可以表示故障类型的严重程度，某故障越严重，其对应的频率值越大，以使减小控制器接收到充电装置信息的时间。此外，充电装置信息的原通信频率由电动车辆控制器设定，原通信频率可以表示电动车辆的通信总线的负载情况，因此本申请实施例获取调整频率时考虑了当前通信总线的负载情况，进而在提高充电装置信息的发送频率时，不会影响电动车辆其他模块的正常工作。
根据本申请的一个实施例，步骤201获取的电动车辆充电装置的充电装置信息进一步包括充电装置的供电电压和开关状态。
在本申请实施例中，当充电装置的供电电压与预设的正常工作电压不符时，充电装置的正常工作将受到影响，导致充电装置故障，因此需要将充电装置的供电电压发送给控制器，以使控制器根据供电电压的大小确定充电装置的故障。此外，充电装置的开关状态与预设的开关状态不符时，充电装置将不能按照控制器设定的充电策略为电动车辆进行充电，导致充电装置故障，增加了充电安全隐患，因此需要将充电装置的开关状态发送给控制器，以使控制器根据开关状态确定充电装置的故障。
在本步骤中，例如预设的充电装置正常工作电压范围为8.4V-16.2V，根据本申请的一个实施例，充电装置供电电压表示的故障类型包括：欠压有功能限制、欠压无功能限制、过压有功能限制、过压无功能限制，上述故障类型对应的供电电压值可以如表1所示。
表1
Figure PCTCN2022129290-appb-000001
根据本申请的一个实施例，为了根据供电电压确定充电装置的故障类型，如图3所示，步骤202进一步包括，
步骤301：计算供电电压与供电电压预设值的差值；
步骤302：根据差值确定电动车辆充电装置的故障类型。
在本申请实施例中，当前的供电电压与供电电压的预设值的差值可以表示充电装置是否出现欠压或过压等情况，若充电装置出现欠压，过低的供电电压将不能满足充电装置各模块的工作需要，若充电装置出现过压，则超高的供电电压将会导致充电装置的某个或某些模块损坏。此外，当出现欠压或过压时，可以通过充电装置的各模块中电子器件的物理特性进一步判断出现故障的具体模块，例如供电电压低于预设的电压值一定范围时，哪些模块仍能正常工作，哪些模块不能正常工作。
因此在本步骤中，计算供电电压与供电电压预设值的差值，根据差值确定电动车辆充电装置的故障类型，以使根据故障类型和充电装置信息的原通信频率获取高于原通信频率的调整频率，并根据调整频率向电动车辆控制器发送充电装置的供电电压，电动车辆控制器根据供电电压确定充电装置的故障。此外，还可以比较供电电压和各故障状态对应的供电电压范围的方法判断充电装置的故障类型，在本说明书实施例中不做限制。
根据本申请的一个实施例，步骤202进一步包括，根据供电电压，以及预先配置的预设供电电压范围与故障类型的对应关系，确定电动车辆充电装置的故障类型。
在本步骤中，可以预先配置如表1所示的供电电压范围与故障类型的对应关系，然后查找充电装置当前的供电电压值所对应的供电电压范围，从而确定当前供电电压值对应的故障类型。例如，当前供电电压为8V，根据表1所示的供电电压范围与故障类型的对应关系，确定当前的故障类型是欠压无功能限制。
结合表1，本申请实施例预设的频率表可以如表2所示：
表2
Figure PCTCN2022129290-appb-000002
根据表2的内容，若原通信频率为200ms，当根据充电装置的供电电压确定充电装置的故障类型为欠压有功能限制时，则以20ms的调整频率向电动车辆控制器发送充电装置的供电电压。
根据本申请的一个实施例，为了避免当根据充电装置的供电电压确定的故障不严重时，充电装置仍以高于原通信频率的调整频率向电动车辆控制器发送充电装置的供电电压造成通信总线压力过大的问题，本申请实施例提供的一种电动车辆充电装置的故障反馈方法还包括，判断充电装置的欠压无功能限制或过压无功能限制的故障类型在预设的时间内是否发生变化；若未发生变化，则充电装置根据原通信频率向电动车辆控制器发送充电装置的供电电压。
在本步骤中，欠压无功能限制和过压无功能限制的故障并不严重，充电装置仍可以正常工作，因此可以在预设的时间内判断充电装置的欠压无功能限制或过压无功能限制的故障类型是否发生变化。其中，预设的时间可以根据调整频率进行设定，例如，调整频率为20ms，则可以在5个调整频率所对应的时间范围内判断充电装置的欠压无功能限制或过压无功能限制的故障类型是否发生变化。若未发生变化，则充电装置根据原通信频率向电动车辆控制器发送充电装置的供电电压，减小电动汽车通信总线的压力。
根据本申请的一个实施例，步骤202进一步包括，根据开关状态，以及预先配置的预设开关状态与故障类型的对应关系，确定电动车辆充电装置的故障类型。
在本步骤中，可以预先配置开关状态与故障类型的对应关系，然后确定充电装置当前的开关状态与属于预先配置的哪个开关状态，从而确定当前开关状态对应的故障类型。
根据本申请的一个实施例，为了及时得到开关状态，从而降低误判的概率，提高故障反馈的精确度，如图4所示，在步骤201之前还包括，
步骤401：获取电动车辆控制器以原通信频率发送的充电策略；
步骤402：执行充电策略得到执行结果，执行结果包括充电装置的开关状态。
在本申请实施例中，控制器以步骤203充电装置信息的原通信频率发送充电策略，充电策略中包括了充电装置的开关状态，充电装置执行充电策略时根据充电策略调整开关状态，从而使得充电桩的电流通过充电装置的开关充入到电动车辆的电池中。在本步骤中，充电装置在执行充电策略之后获取开关状态，提高了获取开关状态的及时性，从而降低误判的概率，提高故障反馈的精确度。
根据本申请的一个实施例，步骤402得到的执行结果中还包括执行状态，该状态表示步骤401的充电策略是否被执行。
在本申请实施例中，充电装置的故障还可以包括未执行充电策略、执行了充电策略但未执行成功，因此步骤202还包括，计算充电装置开关的状态与充电策略的差异，根据差异确定充电装置的故障类型，和/或，根据执行状态确定充电装置的故障类型。
在本步骤中，可以计算充电装置开关状态与充电策略中的开关状态的差异，根据差异找到与充电策略不同的充电装置开关；根据执行状态可以确定充电策略未执行的故障；结合根据差异确定的故障类型和根据执行状态确定充电装置的故障类型，可以确定执行了充电策略但未执行成功的故障。
根据本申请的一个实施例，为了避免在故障消除后，仍通过高于原通信频率的调整频率进行电动车辆充电装置与控制器的通信，造成通信总线压力过大的问题，如图5所示，本申请实施例提供的一种电动车辆充电装置的故障反馈方法还包括，
步骤501：根据充电装置信息判断充电装置是否还存在故障；
步骤502：若不存在故障，则充电装置以原通信频率与电动车辆控制器进行通信。
在本步骤中，充电装置信息可以包括充电装置的供电电压和充电装置的开关状态，可以根据充电装置供电电压与供电电压预设值的差值判断充电装置是否还存在故障，也可以根据充电装置的开关状态和获取到的电动车辆控制器发送的充电策略的差异和/或根据充电策略的执行状态判断充电装置是否还存在故障。若不存在故障了，则充电装置以原通信频率与电动车辆控制器进行通信，减小通信总线的压力，从而保证电动车辆其他模块的正常工作。

步骤814，充电装置执行调整后的充电策略，并判断是否还有故障。
在本步骤中，充电装置在执行调整策略后，通过与步骤806、809相同的方法判断是否还有故障，若仍存在故障，则重复步骤805-811。
此外，充电装置还可以判断充电装置的欠压无功能限制或过压无功能限制的故障类型在预设的时间内是否发生变化；若未发生变化，则充电装置根据原通信频率向电动车辆控制器发送充电装置的供电电压。其中，欠压无功能限制和过压无功能限制的故障并不严重，充电装置仍可以正常工作，因此可以在预设的时间内判断充电装置的欠压无功能限制或过压无功能限制的故障类型是否发生变化。其中，预设的时间可以根据调整频率进行设定，例如，调整频率为20ms，则可以在5个调整频率所对应的时间范围内判断充电装置的欠压无功能限制或过压无功能限制的故障类型是否发生变化。若未发生变化，则充电装置根据原通信频率向电动车辆控制器发送充电装置的供电电压，减小电动汽车通信总线的压力。
步骤815，故障不存在，充电装置根据原通信频率将充电电压和开关状态发送给控制器。
在本步骤中，若不存在故障了，则充电装置以原通信频率与电动车辆控制器进行通信，减小通信总线的压力，从而保证电动车辆其他模块的正常工作。
