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,變電站和配電設備的布局設計應便于安裝、操作、搬運、維護、測試和監控。高低壓配電室、變壓器室、電容器室、控制室,不應有無關的管道和線路穿過。當然,即使很好地解決了充電站的技術瓶頸,充電站的建設仍可能存在選址難等問題。新能源汽車首先要以城市為主,但繁華的ⅸ區往往土地緊缺,地價成本高。這方面需要政策傾斜,推進充電設施建設。電力企業開發運營電動汽車充電站具有先天優勢。電力企業直接向車輛售電是一項新業務, 并且希望電力企業有所改變。
充電樁建設要求:作為電網配電側的電動汽車充電樁(插頭),其結構的特殊性決定了自動通信系統具有測點多且分散、覆蓋面廣、通信距離短的特點。并且隨著城市的發展,網絡拓撲結構需要靈活和可擴展的結構。因此,電動汽車充電樁(插頭)通信方式的選擇應考慮以下問題:
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.通信的靈活性和擴展性——由于充電樁(插頭)具有控制點多、廣、散的特點,因此需要標準的通信協議。隨著網絡技術趨勢的發展和電力運營業務的不斷增長,需要考慮基于IP的業務承載,同時也要求便于安裝、調試、運行和維護。
充電樁的特點:
1.提供人機交互操作;提供DC和交流充電接口;
2、具有語音提示功能;有功能;
3.它具有打印收據的功能;
4.與BMS實時通信,獲取動力電池類型、電池電壓、剩余容量、溫度、報警等信息。
5、對充電器產生控制指令和開關信號,控制充電器的啟動和停止,并獲取充電器的狀態信息;
6、具有充電接口連接狀態判斷、聯鎖功能。
充電樁充電注意事項:
1.充電樁按性質一般分為兩種:公用樁和自用樁。公共樁是通用的,但是要收電費和服務費,成本比較高;自用樁只適合自己的車,不通用;
2.使用公共充電樁時,要看清楚是適合大車還是小車,因為有些老標樁不能給小車充電,反之亦然;
3.充電前,檢查充電樁設備是否完好,線纜和連接器是否完好。如果下雨天沒有雨棚,就不要露天使用充電樁,以防漏電。
4.充電完成后,及時斷開充電樁,防止過度充電。
