Description

一种充电桩供电节能自动控制装置
技术领域
本发明属于充电技术领域，特别涉及充电桩供电节能自动控制装置。
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充电桩得到了大量应用，但目前充电桩场站，大部分充电桩日均充电小时数不足2个小时，一天大部分时间充电桩处于待机状态，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供电节能自动控制装置，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：一种充电桩供电节能自动控制装置，其特征在于，包括接触器KM和控制开关K，所述接触器KM包括线圈和触点开关，所述控制开关K和所述线圈串联在电网的零线和其中一条火线之间形成控制回路，所述触点开关一侧用于连接电网，所述触点开关的另一侧用于连接充电桩。
在上述的充电桩供电节能自动控制装置中，所述控制开关K为时控开关。
在上述的充电桩供电节能自动控制装置中，所述时控开关K的输入和输出电压均为220Vac。
在上述的充电桩供电节能自动控制装置中，所述控制开关K为光控开关。(这一条仅仅作为对控制开关K的扩展方案，起到扩展范围的作用)
在上述的充电桩供电节能自动控制装置中，所述接触器KM为常开型接触器，所述接触器KM的工作电压为220Vac。
与现有技术相比，本充电桩供电节能自动控制装置具有以下优点：本装置在充电桩充电淡时，如深夜充电桩绝大部分时间处于待机时段，这个时候通过设置自动控制电网停止向充电桩供电；在充电旺盛时段，自动控制电网恢复向充电桩供电。实现减少充电桩待机功耗达到节能目的。
附图说明
图1是实施例的充电桩供电节能自动控制装置的电路原理图。
图2是实施例的充电桩供电节能自动控制装置应用在充电站时的原理图。
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，本充电桩供电节能自动控制装置包括接触器KM和控制开关K，接触器KM包括线圈和触点开关，控制开关K和线圈串联在电网的零线和其中一条火线之间形成控制回路，触点开关一侧通过接入开关K1连接电网(图中ac表示，下同)，触点开关的另一侧连接充电桩。
具体的，在本事实例中，接触器KM为常开型接触器，接触器KM的工作电压为220Vac。
控制开关K为时控开关，其为正泰公司生产的型号为KG316T/25A 220Vac的开关器件，其输入和输出电压均为220Vac。时空开关的电源输入端和电网的火线W连接，电源输出端和线圈连接，然后线圈和时控开关的接线端子连接，最后通过接线端子和电网的零线连接。需要说明的是，时控开关的电源输入端和电源输出端之间设置有用于控制电源输入端和电源输出端之间通断的控制模块，由于该开关器件为现有产品，因此其具体功能和结构不做赘述。此外，时控开关在本发明的其他实施例中还可以采用光控开关替代。
本发明的工作原理如下：设置时控开关K在一天之内开通的时间段和断开的时间段，将接入开关闭合，使时控开关K和接触器KM处于上电检测状态。时控开关K在设定开的时间段内，接触器KM的线圈有AC 220Vac的通电回路，接触器KM的触点开关闭合，充电桩通电运行；时控开关K在设定关的时间段内，接触器K的线圈无AC 220Vac的通电回路，接触器K的触点开关断开，充电桩无交流供电输入，大大降低了待机损耗，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。
