Safety requirements for charging piles:
1, substation should be set up safety column, warning signs, safety lights and alarm bells;
2. Warning signs of "Stop, High Voltage Danger" should be hung outside the high voltage distribution room and transformer room or on the safety column of substation. Warning signs must be marked towards the outside of the fence;
3. There should be obvious operation instructions on the high-voltage power distribution device. The grounding point of the equipment should be clearly visible;
4, indoor should have obvious "safe passage" or "safe exit" signs;
此外,变电站和配电设备的布局设计应便于安装、操作、搬运、维护、测试和监控。高低压配电室、变压器室、电容器室、控制室,不应有无关的管道和线路穿过。当然,即使很好地解决了充电站的技术瓶颈,充电站的建设仍可能存在选址难等问题。新能源汽车首先要以城市为主,但繁华的ⅸ区往往土地紧缺,地价成本高。这方面需要政策倾斜,推进充电设施建设。电力企业开发运营电动汽车充电站具有先天优势。电力企业直接向车辆售电是一项新业务, 并且希望电力企业有所改变。
充电桩建设要求:作为电网配电侧的电动汽车充电桩(插头),其结构的特殊性决定了自动通信系统具有测点多且分散、覆盖面广、通信距离短的特点。并且随着城市的发展,网络拓扑结构需要灵活和可扩展的结构。因此,电动汽车充电桩(插头)通信方式的选择应考虑以下问题:
1, the reliability of communication, communication system to withstand the harsh environment and strong electromagnetic interference or noise interference test for a long time, and keep the communication smooth;
2, the construction cost-on the premise of meeting the reliability, comprehensive consideration of the construction cost and long-term use and maintenance costs;
3, two-way communication-not only can realize the upload of information, but also realize the release of control quantity;
4. Multi-service data transmission rate-With the continuous growth of terminal traffic in the future, the communication between the main station and the sub-station and the terminal requires higher and higher data transmission rate for multi-service;
5.通信的灵活性和扩展性——由于充电桩(插头)具有控制点多、广、散的特点,因此需要标准的通信协议。随着网络技术趋势的发展和电力运营业务的不断增长,需要考虑基于IP的业务承载,同时也要求便于安装、调试、运行和维护。
充电桩的特点:
1.提供人机交互操作;提供DC和交流充电接口;
2、具有语音提示功能;有功能;
3.它具有打印收据的功能;
4.与BMS实时通信,获取动力电池类型、电池电压、剩余容量、温度、报警等信息。
5、对充电器产生控制指令和开关信号,控制充电器的启动和停止,并获取充电器的状态信息;
6、具有充电接口连接状态判断、联锁功能。
充电桩充电注意事项:
1.充电桩按性质一般分为两种:公用桩和自用桩。公共桩是通用的,但是要收电费和服务费,成本比较高;自用桩只适合自己的车,不通用;
2.使用公共充电桩时,要看清楚是适合大车还是小车,因为有些老标桩不能给小车充电,反之亦然;
3.充电前,检查充电桩设备是否完好,线缆和连接器是否完好。如果下雨天没有雨棚,就不要露天使用充电桩,以防漏电。
4.充电完成后,及时断开充电桩,防止过度充电。
