The Impact of Sustainable Communities on Low Voltage Distribution Network

Survey

 

With the aim of informing the electric vehicle profiles and therefore achieving justification, the plan and execution of a survey was considered imperative. The framework of the questionnaire was directed towards identifying the current driving habits of the respondents and how these could be aligned with the transition to low carbon transport.

 

The purposes of this survey was to find out the general driving trends of drivers and secondly to analyse peoples’ perception of EVs to predict the likelihood of their implementation.

 

To do so, several questions were formed which addressed the major issue of shifting from conventional and fossil fuelled transportation to low carbon transportation. Key questions of determining whether or not the respondents could have the ability to take advantage of an electric vehicle were the ones related to the daily covered mileage and the access to an existing charging point.

 

There were 14 questions in total and around 100 participants took part with age ranging from 17 to 80 years old. The full survey and the appropriate results can be found below (Scientists, 2013).

Conclusions

  

The main points that the survey relayed was, for example the number of miles driven per day, and this information was used to determine the average energy consumption for the vehicle. This was important as it also informed how much recharging would be required per day. Another key element was to define the behavioural patterns of car users as this would inform the charging rate scenarios, and would give an indication of the spread of electric vehicles in order to quantify the impact of these loads on the wires. Finally, the survey also gave an indication of the future feasibility of integrating electric vehicles into the domestic housing network. This supported the future scenario predictions of progressive levels of electrification with the integration of electric vehicles.
