Feature: the notorious CVT explained
Beside cost and efficiency, two further issues inhibit EV uptake: infrastructure, and how EVS are used.
In 2011, we travelled to California to experience first-hand the burgeoning EV industry in one of the most progressive regions in the world (in terms of green technology). There it quickly became clear that infrastructure would be under duress as more EVS hit the road. Of particular concern is how already burdened electricity suppliers will figure out how to support these consumers.
However, there appears to be an even bigger issue facing EVS: how they will be used.
An EV does – and will continue to do so – require drivers to change their behaviour, specifically when it comes to recharging (versus refuelling, which would happen far less frequently). This is a big headache for companies marketing EVS, simply because consumers are generally stuck in their ways.
The EMERGE study found drivers require that about 25% of charging infrastructure to be public, with more than 50% needed in spaces such as parking garages and other semi-public spaces.
An interesting finding was that night-time charging forms the bottle-neck for infrastructure, because there is generally only one nighttime charge per charging point, whereas several charges are possible during the daytime.
