Over half the time (61.4%) that electric vehicles spend connected to public charging stations, they're idly occupying a space that another car could use, according to a JRC-led study of e-vehicle charging times in the Netherlands.
This 'idle time' occurs when the car has been fully charged but is left plugged in. High idle time obviously reduces the availability of chargers, but it also provides an opportunity for grid operators to balance the grid.
Using data from 1.8 million e-vehicle charging observations in the Netherlands over a 6-year period, the study analyses the factors affecting idle time, providing a methodology to plan effective future charging infrastructures. The study authors also recommend building new charging points in the centre and at the outskirts of the cities that they looked at.
