Description

一种充电桩充电自启动和停止的控制装置
技术领域
本发明属于充电技术领域，特别涉及一种充电桩充电自启动和停止的控制装置。
背景技术
中国是目前世界上第一位能源生产国和消费国，能源需求供应持续增长，随着我国经济社会发展水平不断提高，汽车保有量持续攀升。大力发展电动汽车，能够加快燃油替代，减少汽车尾气排放，对保障能源安全、促进节能减排、防治大气污染、推动我国从汽车大国迈向汽车强国具有重要意义。
当今，燃油汽车每年消耗的石油占世界石油产量的一半以上，石油价格近年来不断上涨表明了人类可用化石能源的紧缺性；汽车发动机排放的废气对大气造成的污染也越来越严重。基于上述原因，电动汽车逐渐成为人们关注的热点之一。完善的充电基础设施体系是电动汽车普及的重要保障。进一步大力推进充电基础设施建设，是当前加快电动汽车推广应用的紧迫任务，也是推进能源消费革命的一项重要战略举措。
随着电动汽车快速增长，为保证电动汽车出行，高压充电场站得到了大量应用，此类充电场站变压器容量较大充电桩数量较多。但目前有部分此类充电场站日均充电小时数不足2个小时，一天大部分时间处于待机状态，一天大部分时间处于待机状态，产生了较大的待机功耗。
发明内容
有鉴于此，本发明的目的在于提供一种充电桩充电自启动和停止的控制装置，目的是解决上述背景技术中提出的问题。
本发明的目的可通过下列技术方案来实现：一种充电桩充电自启动和停止的控制装置，其特征在于，包括用于和配电母线连接的配电支线、光电接近开关K1、继电器KA和接触器KM，所述光电接近开关K1和所述继电器KA的线圈串联后的两端分别连接在配电支线的一条火线和零线上，所述继电器KA的触点开关和所述接触器KM的线圈串联后的两端分别接在配电支线的一条火线和零线上，所述接触器KM的触点开关的一侧和配电支线连接，所述接触器KM的触点开关的另一侧作为配电输出侧用于和充电桩连接。
在上述的充电桩充电自启动和停止的控制装置中，所述光电接近开关K1为常开型开关，其感光头用于朝上安装在充电车位正中间位置。
在上述的充电桩充电自启动和停止的控制装置中，所述继电器KA为常开型继电器。
在上述的充电桩充电自启动和停止的控制装置中，所述接触器KM为常开型接触器。
与现有技术相比，本充电桩充电自启动和停止的控制装置具有以下优点：实现了充电桩在没有电动汽车充电的待机时段，自动控制电网停止向充电桩供电减小待机损耗，当电动汽车进入充电车位准备充电时，自动控制电网恢复向充电桩供电，使充电桩进入充电运行状态，从而实现大幅减少充电桩待机功耗达到节能目的。
附图说明
图1是实施例的充电桩充电自启动和停止的控制装置的电路原理图。
图2是实施例的充电桩充电自启动和停止的控制装置的应用电路原理图。
具体实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
如图1和图2所示，本充电桩充电自启动和停止的控制装置接在配电母线和充电桩之间，在本充电桩充电自启动和停止的控制装置和配电母线之间设有接入开关K2。本充电桩充电自启动和停止的控制装置包括用于和配电母线连接的配电支线、光电接近开关K1、继电器KA和接触器KM，光电接近开关K1和继电器KA的线圈串联后的两端分别连接在配电支线的一条火线和零线上，继电器KA的触点开关和接触器KM的线圈串联后的两端分别接在配电支线的一条火线和零线上，接触器KM的触点开关的一侧和配电支线连接，接触器KM的触点开关的另一侧作为配电输出侧用于和充电桩连接。
具体的说，光电接近开关K1为常开型开关，其感光头用于朝上安装在充电车位正中间位置，其工作电压为交流AC 220V；继电器KA为常开型继电器；接触器KM为常开型接触器。
本发明的工作原理如下：
当充电车辆进入充电车位时光电接近开关K1闭合，此时继电器KA的线圈通电回路导通，继电器KA的触点开关闭合，致使接触器KM的线圈通电回路导通，接触器KM的触点开关闭合，充电桩通电运行；
当充电车辆离开车位时光电接近开关K1断开，此时继电器2的线圈通电回路断开，继电器KA的触点开关断开，致使接触器KM的线圈通电回路断开，接触器KM的触点开关断开，充电桩无交流供电输入，大幅降低了充电桩待机损耗，提升了充电桩能源利用率。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
