Description

车辆插座 技术领域
本发明属于电动汽车技术领域，更具体地说，本发明涉及一种车辆插座。
背景技术
伴随着近年来新能源电动汽车的高速发展与普及，市场上逐渐暴露出一些充电安全事故，充电安全技术的提升愈来愈受重视。
其中，充电功能的实现依赖于充电接口不断耦合的可靠性，但车辆插座在长时间的使用后会有接触不良、积尘、氧化的隐患，这将导致接触电阻过大，当长时间大电流充电时会引起接口过温，发热严重时甚至会导致充电接口或插座的损坏，给充电过程带来极大的安全风险，因此车辆插座温度需要受到监控。
有的车辆插座通过温度传感器和车载控制单元来实现温度的监测，但是这种方式中温度传感器安装的位置距车载控制单元较远，线路长易受信号干扰，导致车载控制单元会经常做出充电异常的错误判断。
目前现有的电动汽车中，车辆插座常集成于整车端，便于实现高压安全的通断控制，所以建议在车辆插座上实现温度监控与过温保护功能，避免高温对充电插头及充电插座的损坏，从而降低充电时的安全隐患。
有鉴于此，确有必要提供一种能实现温度检测和过温保护功能且充电状态判断准确的车辆插座。
发明内容
本发明的目的在于：克服现有技术的不足，提供一种车辆插座，其可以实 现车辆插座的温度检测和过温保护功能，并能对充电状态进行准确的判断。
为了实现上述目的，本发明提供了一种车辆插座，其包括插座、车载控制单元和设置于插座内部的测温装置，其中，所述测温装置包括电源模块、温度检测模块、通信模块和控制器MCU，所述控制器MCU分别与温度检测模块、通信模块和电源模块连接，所述测温装置通过通信模块与车载控制单元连接。
作为本发明车辆插座的一种改进，所述温度检测模块检测车辆插座充电座正负极的温度并通过所述通信模块将实时温度数据发送给车载控制单元。
作为本发明车辆插座的一种改进，所述通信模块通过CAN/LIN信号向车载控制单元发送实时温度数据。
作为本发明车辆插座的一种改进，所述测温装置在车辆插座不充电时处于低功耗的休眠状态。
作为本发明车辆插座的一种改进，所述车载控制单元通过CC2信号电压变化检测到有充电枪插入车辆插座时，车载控制单元通过输出高电平信号使测温装置进入工作状态。
作为本发明车辆插座的一种改进，所述车载控制单元预设有一高温阈值。
作为本发明车辆插座的一种改进，所述车载控制单元接收到的实时温度数据高于所述高温阈值时，车载控制单元进行过温保护，停止充电。
作为本发明车辆插座的一种改进，所述车载控制单元通过减小充电请求电流的方式来进行过温保护。
作为本发明车辆插座的一种改进，汽车的车载供电为所述电源模块提供电能。
相对于现有技术，本发明车辆插座具有以下有益技术效果：
1)充电过程中对车辆插座进行温度检测并具有过温保护功能，有效地避免了高温对充电插头及充电插座的损坏，降低了充电时的安全隐患；
2)简化了现有技术中车载控制单元进行温度检测带来的线长易干扰问题， 并能对充电状态作出准确的判断，减少误判。
附图说明
下面结合附图和具体实施方式，对本发明车辆插座进行详细说明，其中：
图1为本发明车辆插座的模块结构示意图。
具体实施方式
为了使本发明的目的、技术方案及其技术效果更加清晰，以下结合附图和具体实施方式，对本发明进行进一步详细说明。应当理解的是，本说明书中描述的具体实施方式仅仅是为了解释本发明，并非为了限定本发明。
请参照图1所示，本发明车辆插座，其包括插座、车载控制单元和设置于插座内部的测温装置，其中，测温装置包括电源模块、温度检测模块、通信模块和控制器MCU，控制器MCU分别与温度检测模块、通信模块和电源模块连接，测温装置通过通信模块与车载控制单元连接。
测温装置对车辆插座充电时的温度进行在线测量。充电过程中，温度检测模块对车辆插座充电座正负极处的温度进行检测，然后控制器MCU将数据发送至通信模块，通信模块通过CAN/LIN信号将检测到的温度数据发送给车载控制单元。
在不充电时，测温装置处于低功耗的休眠状态，节约能源。当需要充电时，充电枪插入车辆插座内时，车载控制单元检测到CC2信号电压的变化，则通过输出高电平信号唤醒测温装置，使测温装置处于工作状态，在线测量车辆插座充电座正负极处的温度，减低充电时的安全隐患。
当测温装置在线检测过程中，车辆插座的接触不良、积尘、氧化或其他情况可能会导致车辆插座充电过温，高温会对充电插头和车辆插座产生较大的损坏，因此车载控制单元需要预设有一高温阈值；当测温装置检测到的温度高于 这一高温阈值时，车载控制单元会减小充电请求电流，停止充电进行过温保护。
汽车的车载供电为测温装置的电源模块提供电能，无需另外的电源供电。
参照图1所示详细叙述本发明车辆插座的原理和实施过程。
正常不充电状态下，测温装置处于休眠的低功耗状态，当需要进行充电时，插入充电枪，车载控制单元通过CC2信号电压变化检测到有充电插入插座后，车载控制单元输出高电平信号唤醒测温装置，测温装置接收到高电平信号后，进入工作状态。在整个充电过程中，温度检测模块对车辆插座充电座正负极的实时温度进行在线测量，并通过通信模块采用CAN/LIN通信方式向车载控制单元发送所检测到的实时温度数据，车载控制单元预设有一个高温阈值，当车载控制单元接收到的实时温度数据高于预设的高温阈值时，车载控制单元会自动减小充电请求电流，进行过温保护，停止充电，从而降低充电风险，提高系统可靠性。
结合以上对本发明的详细描述可以看出，相对于现有技术，本发明至少具有以下有益技术效果：
1)充电过程中对车辆插座进行温度检测并具有过温保护功能，有效地避免了高温对充电插头及充电插座的损坏，降低了充电时的安全隐患；
2)简化了现有技术中车载控制单元进行温度检测带来的线长易干扰问题，并能对充电状态作出准确的判断，减少误判。
根据上述原理，本发明还可以对上述实施方式进行适当的变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对本发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本发明构成任何限制。
