The global market for EV chargers is set to grow from about one million units in 2014 to more than 12.7 million units in 2020, according to a new EV Charging Infrastructure report by IHS Automotive.

IHS expects public charging to be a small but important part of the picture. In 2020, approximately 10% of EV charging stations will be public or semi-public, according to the report.

According to IHS, about 7% of the world’s EVs use the CCS charging system, and about 65% use the CHAdeMO standard. This is expected to gradually evolve into a more even split.

Japan, which now actually has more EV charging stations than gas stations, is a key growth region for EVSE. Japan has more than 2,800 CHAdeMO fast charging stations, roughly half the global total of all CHAdeMO stations.

In Europe, the Netherlands, the UK and Norway are the nations with the most charging stations and, not coincidentally, some of the highest EV sales.

“We recognize the potential of Germany and France,” said IHS Senior Analyst Ben Scott. “They are the ‘sleeping giants’ of e-mobility, but their EV charging station networks are currently underdeveloped with respect to the size of those countries.”

Another tidbit in the report: in 2016, global PHEV production will exceed pure EV production for the first time, and is expected to remain that way for the short to mid-term.
