In recent years, a new environmental awareness has spread among travelers who in turn are very attentive to the environmental impact of their lifestyle. The modern citizen is in fact increasingly attentive and informed about CO2 emissions and the carbon footprint of his activities. It is exactly this type of approach that leads him to looking for new contexts and forms of expressing his respect for the environment. One way of which is moving around with an electric vehicle. 
It is therefore essential to install publicly available charging points at parking spaces: an opportunity both to promote ecological mobility and to make one's own city more sustainable, attractive and in line with the values of the modern citizens, commuters and tourists.
When planning rollout of public charging infrastructure, it is of paramount importance that the status of the charging station is as transparent and reliable as possible. In order to do that, charging stations publicly available are normally connected to an E-mobility Service Provider back-end.
Users can then access web-based information in order to localize charging stations, verify their status availability, book/reserve the charging point and then, once finished, pay for the service. Nothing is more frustrating than reaching a charging point just to find out it’s out of order or already in use. 
In order to allow a seamless charging experience, reliability of the hardware and ESMP back-end is very important. Same importance is held by providing clear contact information on who to call in case of defaults. TIP: usually there should be a Charge Point Operator (CPO) taking care of the maintenance and correct running of the system. Hardly the hardware manufacturer can provide support in case a charging station is installed and connected to an EMSP. In case you are the final user, try looking for information on the charging station, usually there is a contact number to call in case of need. In case you are the municipality or the owner of the stations, be sure that who is running the service, the CPO, provide visible contact details directly on the station.
Another aspect to keep in mind when deciding what type of infrastructure to choose is how quickly do you wish the users to charge. If the charging point is located along a motorway, or remote area without many services or point of interests, most probably you should choose a mode 4 direct current fast charging station. That should allow the user to receive a good boost of energy in as little as 20 minutes.
If you are instead planning the installation of a charging station in the city center, perhaps close to a shopping mall, restaurant or night life area where you could expect a 2-3 hours parking time, then a slow charging mode 3 charging station could be the right choice as these stress the grid infrastructure less and allows for a good topping up of the battery levels.

Depending on the parking structure you could choose between wall mounting or ground laying solution.
As pillar formed charging stations are sturdier we usually suggest these for city like installation. They also have increased visibility and allow for higher customization levels in case you wish to promote a specific advertising or message.
