Electric charging locations Hamburg

The dataset contains the locations of the publicly accessible charging facilities for electric vehicles in the model region of electromobility Hamburg. The related factual information such as number of charging points, plug types and access options are included. In addition, the operating status (UNKNOWN, AVAILABLE, OCCUPIED, RESERVED, UNAVAILABLE, FAULTED, PREPARING, CHARGING, SUSPENDEDEDEV, SUSPENDEDEVSE, FINISHING) of the charging points is indicated in real time.

More information about the real-time service:

The real-time data service contains the locations of the publicly accessible charging facilities for electric vehicles in the model region of electromobility Hamburg in JSON format provided via the SensorThings API (STA). For the e-charging stations in the SensorThings API (STA), one object was created for each station in the entity “Thing”. For each charging point, an object stands in the entity “Datastreams”. The real-time data on the status of the charging point is published in the STA in the entity “Observations”.

All dates are given in Coordinated Universal Time (UTC).

In the entity Datastreams there are further “key value pairs” in the JSON object under the “key” “properties”. Based on the service and layer structure in the GIS, we introduced Service and Layers as additional “key-value pairs” under the JSON object properties.

{
“properties”:{
“service name”: “HH_STA_E charging stations”,
“layer name”: “Status_E charging point”,
“key”:“value”}
}

These “key-value pairs” can then be used to define filters for the REST request, e.g.
https://iot.hamburg.de/v1.1/Datastreams?$filter=properties/serviceName eq ‘HH_STA_E-Chargingstations’ and properties/Layername eq ‘Status_E-Chardepunkt’

The real-time data can also be obtained via an MQTT broker. The necessary IDs can be obtained via a REST request and then used for the subscription to a data stream:

MQTT broker: iot.hamburg.de
Topic: v1.1/Datastream({id})/Observations

本数据集收录汉堡电动汽车示范区域内面向公众开放的电动汽车充电设施点位信息，同时包含充电桩数量、插头类型、使用权限等相关详实参数。此外，还实时标注了各充电桩的运行状态，状态包括：未知（UNKNOWN）、可用（AVAILABLE）、已占用（OCCUPIED）、已预约（RESERVED）、不可用（UNAVAILABLE）、故障（FAULTED）、准备中（PREPARING）、充电中（CHARGING）、SUSPENDEDEV、SUSPENDEDEVSE、收尾中（FINISHING）。

关于实时数据服务的更多说明：
本实时数据服务以JSON格式提供汉堡电动汽车示范区域内面向公众开放的电动汽车充电设施点位信息，可通过SensorThings API（STA）获取。在SensorThings API（STA）中，每个充电站对应实体“Thing”下的一个对象；每个充电桩则对应实体“Datastreams”下的一个对象。充电桩状态的实时数据发布于该API的“Observations”实体中。

所有日期均采用协调世界时（UTC）标注。

在Datastreams实体的JSON对象中，"properties"字段下包含额外的键值对。结合GIS中的服务与图层架构，我们额外新增了“service”与“layers”两类键值对至JSON对象的properties字段中。
{
"properties":{
"service name": "HH_STA_E充电设施",
"layer name": "Status_E充电点",
"key":"value"}
}

此类键值对可用于为REST请求定义筛选条件，例如：
https://iot.hamburg.de/v1.1/Datastreams?$filter=properties/serviceName eq 'HH_STA_E-Chargingstations' and properties/Layername eq 'Status_E-Chardepunkt'

实时数据还可通过MQTT代理获取。所需的ID可通过REST请求获取，随后可用于订阅数据流：
