摘要: 给出了天津市4个充电桩数据采集平台的统计数据。数据表明充电桩电量分布具有长尾特征和整体与局部自相似的幂律特征。据此得出了尾部少数充电桩极其重要、头部充电桩几乎无人问津的结论,并提出了计量资源分配应抓尾放头、利用头部试错成本低的优势、鼓励多元化小范围技术尝试和模式创新的建议。

关键词: 充电桩, 计量, 检定, 幂律分布, 长尾分布

Abstract: The statistical data of four charging pile data collection platforms in Tianjin are given. The data show that the electric quantity distribution of the charging pile has long tail characteristics and power law characteristics of global and local self similarity. It is concluded that a few charging piles at the tail are extremely important and few charging piles at the head are paid attention to. The paper puts forward some suggestions that the distribution of measurement resources should focus on the tail and leave the head,and encourage diversified small-scale technology attempts and mode innovation by taking advantage of the low cost of trial and error at the head.

Key words: charging pile, metrology, verification, power law distribution, long-tailed distribution
