本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
图1是本发明的具有充电安全的电动汽车的第一实施例的结构框图。如图1所述，本发明的具有充电安全的电动汽车包括：车体100、设置在所述车体100上的充电座10。通常充电座10是通过传统汽车上的加油口改造，一般设置在车体100的外板上。在充电时，将供电设备的充电插头20插入充电座10中，待供电设备和车体100的控制器连接确认之后，就可以对车体100内的电池，通常是锂电池组进行充电了。
在本实施例中，进一步设置了接触传感器30，以用于检测所述充电座10与充电插头20之间的接触状态。在本发明的一个优选实施例中，所述接触传感器30为设置在所述充电座10上以检测所述充电座10与充电插头20之间的物理接触的物理接触传感器。在本发明的另一个优选实施例中，所述接触传感器30位设置在充电电路中，以检测所述充电座10与充电插头20之间的电接触状态的电接触传 感器。本领域技术人员知悉，本领域中任何已知的物理接触传感器(例如压敏检测器)、电接触传感器(电流、电压检测器)均可以用于本发明。
所述接触传感器30与驻车控制器40通信连接。所述驻车控制器40可以是整车控制器的一部分，或者其中运行的程序模块，其用于启动驻车控制。当所述接触传感器30检测到所述充电座10与充电插头20接触时，可以认为正在对电动汽车进行充电，这时所述驻车控制器40启动驻车控制。而当所述接触传感器30检测到所述充电座10与充电插头20没有接触时，可以认为没有对电动汽车进行充电，这时所述驻车控制器40关闭驻车控制。
在本发明中，驻车控制可以是指汽车领域中正常情况下的停车止动，也可以包括停止电动汽车中跟强电和/或弱电有关的带电动作，即可以包括将整个电动车辆锁死，而无法开动。
实施本发明的具有充电安全的电动汽车，通过检测充电座与充电插头之间的接触状态，从而启动驻车控制，从而避免了车主忘记汽车正在充电就贸然启动车辆将车启动行驶，有效地避免了事故发生。
图2是本发明的具有充电安全的电动汽车的第二实施例的结构框图。如图2所示，本发明的具有充电安全的电动汽车包括：车体100、设置在所述车体100上的充电座10、用于封闭所述充电座10的充电座盖50。在充电座盖50上设置有用于检测所述充电座盖50是否封闭所述充电座10的合盖检测器51。如图2所示，该具有充电安全的电动汽车还包括接触传感器30、驻车控制器40、第一播放控制器60和播放装置70。所述接触传感器30与驻车控制器40通信连接。所述第一播放控制器60分别与所述接触传感器30和所述合盖检测器51通信连接。所述播放装置70与所述第一播放控制器60电连接。
通常充电座10是通过传统汽车上的加油口改造，一般设置在车体100的外板上。在充电时，将供电设备的充电插头20插入充电座10中，待供电设备和车体100的控制器连接确认之后，就可以对车体100内的电池，通常是锂电池组进行充电了。
充电座盖50可以设置在充电座10的一侧，在充电时打开充电座盖可以露出充电座10。合盖检测器51可以设置在充电座盖50上，以检测所述充电座盖50是否封 闭所述充电座10。在本发明的一个优选实施例中，所述合盖检测器51可以是物理接触式检测器，例如压敏检测器，可以通过在充电座盖50封闭所述充电座10时对其的挤压进行检测，也可以是非接触式检测器，例如光敏检测器，当充电座盖50封闭所述充电座10时，其检测到的光线较弱，而当充电座盖50没有封闭所述充电座10时，其检测到的光线往往较强。当然，还可以采用其他的检测器作为本发明的合盖检测器51，只要其能够完成合盖检测即可。
在本实施例中，所述接触传感器30为设置在所述充电座10上以检测所述充电座10与充电插头20之间的物理接触的物理接触传感器。所述驻车控制器40可以是整车控制器的一部分，或者其中运行的程序模块，其用于启动驻车控制。当所述接触传感器30检测到所述充电座10与充电插头20接触时，可以认为正在对电动汽车进行充电，这时所述驻车控制器40启动驻车控制。而当所述接触传感器30检测到所述充电座10与充电插头20没有接触时，可以认为没有对电动汽车进行充电，这时所述驻车控制器40关闭驻车控制。
在本实施例中，所述接触传感器30和合盖检测器51同时通信连接第一播放控制器60。这时，当所述接触传感器30检测到所述充电座10与充电插头分离而同时所述合盖检测器51检测到所述充电座盖50没有封闭所述充电座10，这时我们认为没有对电动汽车进行充电，但是充电座盖50确是打开的，这时第一播放控制器60将控制播放装置70以播放语音提示，要求驾驶员采用所述充电座盖50封闭所述充电座10，这样可以防止驾驶员遗忘封闭充电座10造成的危险。在所述合盖检测器51检测到所述充电座盖50封闭所述充电座10之后，第一播放控制器60将控制播放装置70以停止播放语音提示。在本发明的另一优选实施例中，所述合盖检测器51同样通信连接所述驻车控制器40以进行启动或者关闭所述驻车控制。当所述合盖检测器51检测到所述充电座盖50没有封闭所述充电座10，这时所述驻车控制器40启动驻车控制。这样，只有当所述接触传感器30检测到所述充电座10与充电插头20没有接触时，而且所述合盖检测器51检测到所述充电座盖50封闭所述充电座10这时，所述驻车控制器40才关闭驻车控制。在本实施例中，所述驻车控制器40和第一播放控制器60可以分别是整车控制器的一部分，或者其中运行的程序模块，其用于启动驻车控制和第一语音播放。
在图2所示的优选实施例中，该具有充电安全的电动汽车还包括设置在所述车体100上的并在进行充电时启动的红外感应器81，分别连接红外感应器81和播放装置70的第二播放控制器80。在本发明中，所述红外感应器81可以通过供电设备的充电插头20插入充电座10之后构成的充电回路供电，这样红外感应器81就只会在进行充电时才会启动。当红外感应器81感应到设定距离内有人靠近时，其将检测信号发送给第二播放控制器80，这时，第二播放控制器80将发出警报或者语音提示。在本实施例中，所述第二播放控制器80也可以是整车控制器的一部分，或者其中运行的程序模块，其用于第二语音播放。在本发明的简化实施例中，可以不设置红外感应器81和第二播放控制器80。在本发明的另一优选实施例中，可以在车体100的四个方向上分别设置四个红外感应器81，这样可以避免在充电时有人靠近车体100，从而造成事故。
实施本发明的具有充电安全的电动汽车，通过检测充电座与充电插头之间的接触状态，从而启动驻车控制，从而避免了车主忘记汽车正在充电就贸然启动车辆将车启动行驶，有效地避免了事故发生。进一步地，通过语音提醒避免车主忘记关闭充电座盖以及在充电时靠近，保障了电动汽车的充电安全。
图3是本发明的具有充电安全的电动汽车的第三实施例的结构框图。如图3所示，本发明的具有充电安全的电动汽车包括：车体100、设置在所述车体100上的充电座10、用于封闭所述充电座10的充电座盖50、在充电座盖50上设置的用于检测所述充电座盖50是否封闭所述充电座10的合盖检测器51、接触传感器30、驻车控制器40、第一播放控制器60、播放装置70、红外感应器81和第二播放控制器80，其功能、连接关系均与图2所示实施例近似，在此就不再累述。
图3所示实施例与图2所示实施例的区别在于，所述车体进一步包括锂电池组82，以及连接所述锂电池组82和所述充电座10的充电回路90。图4是图3所示的充电回路90的电流原理图。
如图4所示，所述充电回路90包括与所述锂电池组82串联的充电接触器91、熔断器96以及用于控制所述充电接触器91通断的电池管理器95。所述锂电池组82的两极可以分别连接电流传感器93和电压传感器94以分别用于检测所述锂电池组82的串联电流和串联电压。在本优选实施例中，所述锂电池组82的每个锂电 池上可均设置有温度传感器92，以用于检测其实时温度。该温度传感器92可以是热敏电阻构成的采样电路。在本实施例中，所述充电接触器91可以是控制开关。
在本实施例中，所述电池管理器95包括：过流控制模块951、过压控制模块952和过温控制模块953，其分别与电流传感器93、电压传感器94和温度传感器92通信连接。所述过流控制模块951用于将电流传感器93检测到的所述串流电流与预设电流进行比较，在串流电流高于预设电流时判定发生了过流，这时可能出现了电池满充或者过充，因此所述过流控制模块951将控制所述充电接触器91关断。所述过压控制模块952用于将电压传感器94检测到的所述串流电压与预设电压进行比较，在串流电压高于预设电压时判定发生了过压，这时可能出现了电池满充或者过充，因此所述过压控制模块952将控制所述充电接触器91关断。所述过温控制模块953与各个温度传感器92通信连接以接收每个锂电池的实时温度。所述过温控制模块953将接收到的每个实时温度分别与预设温度进行比较，在任何一个实时温度大于预设温度时，均将控制所述充电接触器91关断。
在本发明的简化实施例中，可以仅设置过流控制、过压控制和过温控制中的至少一者或两者。当然在本发明的优选实施例中，建议如上所述，对三者均进行控制。在本发明中，可以采用已知的任何比较电路、模块或者装置来实现上述过流控制模块951、过压控制模块952和过温控制模块953。
实施本发明的具有充电安全的电动汽车，通过检测充电座与充电插头之间的接触状态，从而启动驻车控制，从而避免了车主忘记汽车正在充电就贸然启动车辆将车启动行驶，有效地避免了事故发生。进一步地，通过语音提醒避免车主忘记关闭充电座盖以及在充电时靠近，保障了电动汽车的充电安全。再进一步地，通过检测电池的电流、电压和/或温度，并在过温、过压和/或过流时迅速断电，对电池进行了额外保护，大大提高了电动汽车的充电安全性和可靠性。
而且，尽管已经相对于一个或多个实现方式示出并描述了本公开，但是本领域技术人员基于对本说明书和附图的阅读和理解将会想到等价变型和修改。本公开包括所有这样的修改和变型，并且仅由所附权利要求的范围限制。特别地关于由上述装置或设备行的各种功能，用于描述这样的装置或设备的术语旨在对 应于执行所述装置或设备的指定功能(例如其在功能上是等价的)的任意装置或设备(除非另外指示)，即使在结构上与执行本文所示的本公开的示范性实现方式中的功能的公开结构不等同。此外，尽管本公开的特定特征已经相对于若干实现方式中的仅一个被公开，但是这种特征可以与如可以对给定或特定应用而言是期望和有利的其他实现方式的一个或多个其他特征组合。
本发明实施例中的各装置或设备、模块可以集成在一个装置或设备中，也可以是各个单独的物理存在，也可以两个或两个以上装置或设备、模块集成在一个装置或设备、模块中。上述集成的装置或设备、模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。
