其中,激活无线通讯天线的过程为:在接收目标车辆到达预设充电位置触发的信号后,激活无线通讯天线。需要进行说明的是,无线通讯天线包括车载无线通讯天线和地面无线通讯天线;激活无线通讯天线即代表目标车辆和充电设备建立连接实现通信。
根据获取的数据信息判断目标车辆是否故障,若目标车辆没有故障,则对目标车辆进行充电;若目标车辆有故障,接下来需要判断目标车辆的故障是否为严重故障,若目标车辆的故障为严重故障,则禁止对目标车辆进行充电,充电设备直接回到待机状态;其中,严重故障包括但不限于目标车辆电源烧损、电源接地故障等原因;可以理解的是,严重故障的定义可根据实际需求增减。
当目标车辆的故障为非严重故障时,判断目标车辆是否允许以预设功率进行充电,若是,则以预设功率对目标车辆进行充电;若否,则禁止对目标车辆进行充电;其中,预设功率为低于目标车辆额定功率的功率。
需要进一步说明的是,上述对目标车辆进行充电的过程包括:
比较对目标车辆进行充电的实际电压与目标车辆的额定电压;若实际电压的数值等于额定电压的数值,则以额定电压对目标车辆进行充电;
若实际电压的数值小于额定电压的数值,则以额定功率对目标车辆进行充电。
可见,本发明实施例提供的智能充电方法,通过无线通讯天线完成目标车辆和充电设备之间的通信,利用预先确认车辆及充电设备的状态信息, 提高对目标车辆智能充电时的安全性、可靠性。
本发明实施例还公开了另外一种智能充电方法,如图3所示,包括:
步骤S21:获取供电的电网电压,判断电网电压是否为预设工作电压的范围。
其中,目标车辆进入充电站后,车顶的受电弓与电网接触,使充电设备获取供电的电网电压。需要进行说明的是,预设工作电压为用户根据需要设置的,通常情况下,预设工作电压为范围为360V至900V。当然,若用户有其他范围的电压要求可以根据需要进行设置。
需要进一步说明的是,上述目标车辆包括但不限于电动车辆,包括但不限于有轨电车、储能式无轨电车、纯电动大巴及电动汽车。充电设备通常为地面充电设备,当然,必要情况下,也可以是其他形式的充电设备。
步骤S22:若电网电压为预设工作电压范围内时,利用激活的无线通讯天线,获取目标车辆的数据信息,并根据获取的数据信息判断目标车辆是否故障,若否,则对目标车辆进行充电。
其中,激活无线通讯天线的过程为:在接收目标车辆到达预设充电位置触发的信号后,激活无线通讯天线。需要进行说明的是,无线通讯天线包括车载无线通讯天线和地面无线通讯天线;激活无线通讯天线即代表目标车辆和充电设备建立连接实现通信。
根据获取的数据信息判断目标车辆是否故障,若目标车辆没有故障,则对目标车辆进行充电;若目标车辆有故障,接下来需要判断目标车辆的故障是否为严重故障,若目标车辆的故障为严重故障,则禁止对目标车辆进行充电,充电设备直接回到待机状态;其中,严重故障包括但不限于目标车辆电源烧损、电源接地故障等原因;可以理解的是,严重故障的定义可根据实际需求增减。
当目标车辆的故障为非严重故障时,判断目标车辆是否允许以预设功率进行充电,若是,则以预设功率对目标车辆进行充电;若否,则禁止对目标车辆进行充电;其中,预设功率为低于目标车辆额定功率的功率。
需要进一步说明的是,对目标车辆进行充电的过程包括:
比较对目标车辆进行充电的实际电压与目标车辆的额定电压;若实际电压的数值等于额定电压的数值,则以额定电压对目标车辆进行充电;
若实际电压的数值小于额定电压的数值,则以额定功率对目标车辆进行充电。
步骤S23:在利用激活的无线通讯天线,接收目标车辆离开预设充电位置触发的信号后,停止对目标车辆进行充电。
需要进行说明的是,目标车辆离开预设充电位置发生的情况可能是突发紧急情况,需要目标车辆离开预设充电位置。
为了避免在充电过程中,因充电设备突发故障继续充电造成的安全事故,本发明实施例还包括:
充电设备的无线通信天线向目标车辆发送充电设备故障的信息;其中,目标车辆根据接收的信息,判断充电设备故障是否影响充电设备对目标车辆的正常充电,若是,则停止通过充电设备进行充电。
可以理解的是,若否,即充电设备故障不影响充电设备对目标车辆的正常充电,则继续充电。
为了实现对目标车辆充电过程的远程监控,本发明实施例还包括:
利用无线通讯天线向预设终端发送充电数据信息,以使预设终端远程监控目标车辆的充电过程。
需要进行说明的是,利用无线天线接收车辆信息,并向后台发送信息,在线路拥堵情况下,前后车辆合理利用地面充电设备充电,避免线路拥堵。例如,前一辆车进站时,若收到请求信息,后一辆车电压较低,急需进站充电,前一辆车选择越站通行,即不充电,给后一辆车预留足够的充电时间。
具体的,通过终端监控充电时的充电参数,可发送预警信息至运营监控后台,从而及时对车辆或线路进行检查检修。例如,充电设备采用恒定电流对相同参数的车载电源进行充电时,电源上升斜率应该基本一致,如出现电压斜率上升异常,则可判定电源容量异常的故障或线路存在漏电、接地不良等问题。以超级电容电池为例,I为充电电流,△t为充电时间,C为电容容量,△U为电容电压上升值,其中,I×△t=C×△U,那么电压上 升斜率λ=△U/△t=I/C,因I与C均为恒定值,因此电压上升斜率λ也为恒定值,如果出现某一列车充电时电压上升异常,地面充电设备即可判断车辆或线路存在故障,立即停止充电并通过无线通讯模块将信息告知车辆及预设终端。
本发明实施例还提供了一种智能充电方法的具体实施方式。图4为本发明实施例提供的一种智能充电方法的具体实施方式中智能充电方法对应的硬件结构图,包括:
车载储能电源通过与车辆的通讯网络将自身的电压、温度、接地状态及故障等信息发送给目标车辆,目标车辆将从储能电源各***接收的信息通过识别选择,发送给车载无线通讯控制模块,无线通讯控制模块将信息处理后再通过车载无线通讯天线传输至地面设备。需要进行说明的是,车载储能电源可根据实际需要增加车载其他***。
地面无线通讯天线接收车载无线通讯信息后,将信息传输至地面无线通讯控制模块,地面充电设备根据通信协议对接收到的数据判断和处理,从而决定是否进行充电、是否降功率充电等响应。
本具体实施方式中,充电逻辑***具有双向性,同样,地面充电设备通过通讯网络将自身异常状态信息或故障发送至车辆,车辆可自行选择是否在本站充电或降下受电弓直接越站通行。
如图5所示,为本发明具体实施方式的充电逻辑示意图。当车辆进站时,地面充电设备首先判断电网电压是否为规定电压值范围内;电网电压值处于正常范围,然后识别地面无线天线是否被激活,即是否与车载天线建立联系,如被激活,则表示车辆处于站台充电位置;然后判断是否接收到车辆发送给地面充电设备故障信息,如没有故障信息,则按照额定功率进行充电;正在充电时,如地面无线天线接收到车辆出站信号,地面充电设备则立即停止充电,防止车辆充电过程中强行出站造成设备损坏。
在图5中,充电设备无线被唤醒后,如车辆报告发送故障信息给地面无线天线,充电设备将根据约定好的通讯协议对故障类型及故障严重程度判断处理,如发生故障为影响车辆运行或存在对设备人员有较大安全隐患的 严重故障,例如电源烧损、电源接地故障等,充电设备将禁止充电,直接回到待机状态。如非严重故障,充电设备将根据故障类型判断,例如并联电源某一路电源发生断路故障、车载储能电源温度达到预警值等,充电设备允许降功率进行充电,从而保障车辆正常运行至车库进行维修。
该充电模式下,地面充电设备可根据预先定义的故障类型、故障程度,进行相应的判断及响应,进行额定功率充电、降功率充电或禁止充电,从而实现自适应调节充电的目的,在保障安全充电的前提下,最大限度的提高智能充电的可靠性。
如图6所示,为地面充电设备故障时,车辆的进站逻辑。因储能式有轨电车车顶受电弓长期处于升弓状态,当车辆进站时,如地面充电设备已经发生短路等故障,地面故障将造成车上设备故障或安全风险。本发明智能充电方法具备双向监测功能,在地面充电设备发生故障时,地面故障信息能通过地面无线通讯天线发送至车辆,车辆在接收到地面故障信息后,将对故障信息做出识别并做出相应响应,如故障信息影响车辆正常充电或具有造成车辆设备故障的风险,车辆将自动降下受电弓进站,待乘客上下车辆完毕后,直接出站运行至下一站。
此外,该发明智能充电方法还具有智能监控功能,通过监控充电时的充电参数,可发送预警信息至运营监控后台,从而及时对车辆或线路进行检查检修。例如,充电设备采用恒定电流对相同参数的车载电源进行充电时,电源上升斜率应该基本一致,如出现电压斜率上升异常,则可判定电源容量异常的故障或线路存在漏电、接地不良等问题。以超级电容电池为例,I为充电电流,△t为充电时间,C为电容容量,△U为电容电压上升值,I×△t=C×△U,那么电压上升斜率λ=△U/△t=I/C,因I与C均为恒定值,因此电压上升斜率λ也为恒定值,如果出现某一列车充电时电压上升异常,地面充电设备即可判断车辆或线路存在故障,立即停止充电并通过无线通讯模块将信息告知车辆及运营后台。
相应的,本发明还提供了一种智能充电***,应用于充电设备,如图7所示,包括:

充电模块12:若所述电网电压在预设工作电压范围内时,利用激活的无线通讯天线,获取目标车辆的数据信息,根据获取的数据判断目标车辆是否故障,若否,则对目标车辆进行充电。

充电模块,用于当目标车辆为非故障时,对目标车辆进行充电。
本发明实施例还提供了一种计算机可读存储介质,计算机可读存储介质上存储有智能充电程序,智能充电程序被处理器执行时实现上述智能充电方法的步骤。
