Electric car development also requires the rollout of a specific supply network. Each electric vehicle needs at least one charging point in the garage and posts in streets, companies and service stations that guarantee the vehicles can be kept on the road. According to IDAE information, in Spain there are already 472 charging points in service. 421 are single-phase (slow charging) and 51 are three-phase (semi-fast charging).
There are currently three charging types: slow, in single-phase AC (domestic) which charges the batteries in 6-8 hours; semi-fast charging, in three-phase AC: between 1.5 and 3 hours; and fast charging, in DC, which now makes it possible to charge batteries in 15-30 minutes. “Most charging will be slow, at night, in the privacy of the vehicle garage, whilst public charging will be semi-fast or fast,” explained Palacio.
The EU is also working on another question that needs to be resolved: standardising the plug-in system so that drivers can refuel anywhere. There are several different manufacturer standards coexisting on the market and each make of cars is only compatible with one of them.
