先对本申请实施例中涉及的部分用语进行解释说明，以便于本领域技术人员容易理解。

为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
电动汽车，又可以称为新能源汽车，是一种利用电能驱动的汽车。参阅图1所示，电动汽车10主要包括：电池管理***11、动力电池12、电机13和车轮14。
其中，动力电池12为大容量、高功率的蓄电池。动力电池12可以向电动汽车10的部分或全部组件提供电能。在一些示例中，动力电池12可以由一个或多个可再充电锂离子或铅酸电池组成。此外，动力电池12还可以采用其它的电源材料和配置，这里不做限定。在电动汽车10行驶时，动力电池12可以通过电池管理***11中的电机控制器(motor control unit，MCU)为电机13供电，电机13将动力电池12提供的电能转换为机械能，从而驱动车轮14转动，实现电动汽车10的行驶。
而在电动汽车10充电时，一般可以通过充电桩20为电动汽车10的动力电池12充电。继续如图1所示，充电桩20主要包括电源电路(图1中未示出)和充电枪21。电源电路的一端与电网30连接，另一端通过线缆与充电枪21连接。操作人员可以将充电枪21***电动汽车10的充电插口，使充电枪21与电动汽车10内的电池管理***11实现连接，充电桩20的电源电路进而可以通过充电枪21为动力电池12充电。
根据国标《电动汽车传导供电***标准》的规定，充电桩20与充电插口除了存在交流电连接之外，还存在两个信号端口，分别为用于传输CP信号的CP信号端口，和用于传输CC信号的CC信号端口。其中，充电插口的CC信号端口与电池管理***11之间为纯 电阻性，而CP信号为PWM波。
在充电枪21***充电插口后，电池管理***11通过对比CC信号识别端口与电池管理***11之间的电阻值，来判断出充电桩20的供电能力以及连接充电桩20与电池管理***11之间的充电电缆类型；同时电池管理***11还通过CP信号的占空比来确定该充电桩20的输出功率。在所述电池管理***11根据充电桩20的供电能力和输出功率完成相关充电配置之后，所述电池管理***11控制电动汽车10内部的车载充电器(on board charger，OBC)接收由充电桩20提供的电能，从而为动力电池12充电。
当充电桩20不向电动汽车10提供电能时，电动汽车10中的电池管理***11会进入休眠状态，从而节省电能，防止动力电池12亏电。因此，休眠后的电池管理***11无法保持一定的电压来监测CC信号，从而无法再次唤醒电池管理***11。
此时，若需对充电电池12继续充电，必须有人到现场在电动汽车10的充电插口上重新插拔充电枪21或重启电动汽车10/充电桩20才能唤醒电池管理***11。
由于目前唤醒电池管理***11需要人工参与，导致用户体验较差。因此，亟待提出一种新的电池管理***111唤醒方法，以实现电动汽车10充电的远程控制，提高用户体验。
有鉴于此，本申请提供的一种充电控制装置、方法及电动汽车。本方案中，在充电控制装置接收到任意类型的CP信号后，根据CP信号能生成目标时长的高电平信号，利用目标时长的高电平信号作为唤醒信号来唤醒电池管理***，从而实现单次唤醒功能。并且，无论充电控制装置接收到何种类型的CP信号，最终生成的唤醒信号都是一个固定脉宽及固定电压幅值的信号。利用上述装置，即使在充电过程中停电后再次来电，也无需在电动汽车的充电插口重新插拔充电枪或重启电动汽车/充电桩，充电控制装置只要再次接收到任意CP信号后，即可通过目标时长的高电平信号来唤醒电池管理***，继续进行充电。
