A study by Trinity College Dublin on the charging behaviour of EV owners has proven one point most in the industry already knew : EV users tend to carry out the majority of their charging at home in the grid , which is obviously the period of highest demand on the electrical grid , indicating that incentives or delays may be required to shift charging away from this peak grid charging period . Furthermore , the study has shown that parking locations were the most popular locations for public charging and that fast chargers recorded the highest charging rates . This lead the authors to conclude that public fast charging infrastructure is most likely to become commercially viable in the medium to medium - term .
A study by Trinity College Dublin on the charging behaviour of EV owners has proven one point most in the industry already knew: EV users prefer to carry out the majority of their charging at home in the evening, which is obviously the period of highest demand on the electrical grid, indicating that incentives or delays may be required to shift charging away from this peak grid demand period. Furthermore, the study has shown that parking locations were the most popular location for public charging and that fast chargers recorded the highest usage frequencies. This lead the authors to conclude that public fast charging infrastructure is most likely to become commercially viable in the short- to medium-term.
