Description

一种固定式电动汽车充电装置及其充电方法
技术领域
本发明涉及电动汽车以及新能源应用领域，尤其涉及一种具有存储电能功能的充电装置及其充电方法。
背景技术
汽车是造成全球石油危机和温室气体排放的主要原因之一，发展清洁能源汽车迫在眉睫。电动汽车的应运而生及其迅速发展代表了新能源汽车发展的方向，与电动汽车有关的新技术已成为各国产业竞争的战略制高点，开发电动汽车方面的高新技术产品，占领战略制高点，对我国的能源安全，节能减排以及汽车产业实现跨越式发展具有重大的战略意义和经济价值。
发展电动汽车离不开补充电能的充电装置，传统的电动汽车充电装置一般采用电网供电，与电网发生密切的关联，一旦某些偏远地区供电不足，或者一些供电系统的重要设备发生故障而中断供电，充电装置就不可以工作，这就限制了电动汽车在偏远地区电网不普及区域公路的行驶，制约了电动汽车的普及，也使得一些风能或太阳能较为富裕的地区，不能将该些能源充分利用。
发明内容
针对上述现有技术的不足，本发明提供了一种固定式电动汽车充电装置及其充电方法，既能存储电网电源在充电状态时提供的电能，又能利用新能源发电对储能电池进行充电，既解决了当供电系统停止工作时的供电问题，又利用了风能或太阳能等清洁新能源，具有有益的技术效果。
本发明所述的充电装置和充电方法，主要技术方案如下：
一种固定式电动汽车充电装置，包括交流/直流转换器(1)、储能电池(2)、以及直流/直流转换器(3)，其特征在于：所述交流/直流转换器(1)的一端连接电网电源，另一端连接所述储能电池(2)的一端，为所述储能电池(2)进行充电；所述交流/直流转换器(1)的所述另一端连接所述直流/直流转换器(3)的一端，经转换后直接向用电设备(6)供电；当所述电网电源供电发生故障时，切换所述储能电池(2)向所述用电设备(6)进行供电。
一种固定式电动汽车充电装置的充电方法，其特征在于包括如下步骤：步骤一、电网电源供电后，通过交流/直流转换器(1)转换输出，所述输出一路连接直流/直流转换器(3)直接向用电设备(6)供电；另一路直接连接储能电池(2)，为所述储能电池(2)充电；步骤二、当电网电源供电发生故障时，切换所述储能电池(2)向所述用电设备(6)进行供电。
优选地，充电装置还包括风能发电装置或太阳能发电装置，为所述储能电池(2)进行充电储能。
本发明具有以下优点和有益效果：
1、具有储能装置，可以解决当电网供电系统停止工作时，为电动汽车供电的问题；
2、拥有多种充电方式(包括风能、太阳能、市电网等)为储能电池进行充电储能，多种充电方式可一起充电，也可以根据环境的不同切换成某一种充电方式单独运行，给充电装置的充电性能提供了有力的保障；
3、为储能电池进行充电储能时，可以在充电装置给用电设备进行供电的状态下进行，极大地提高了充电效率。
4、充电装置既可以采用电网电源给用电设备供电，也可以采用储能电池给用电设备供电，提高了充电保障。
