A Navigant Research study says that there are 48,705 publically accessible chargers available worldwide as of the end of March 2013.
This number is made up of mostly (more than 94%) standard AC charging, like those found in most residential, or workplace applications. Typical applications of AC charging are of the Level 1 (120 V) variety, which provide up to 1.9 kW, and Level 2 (240 V), which can provide up to 19.2 kW.
Another 5% of the public stations are DC/fastcharging, which is quite pricey to install, but power outputs range from 20 kW to 100 kW, with most vehicles capable of accepting up to 50 kW. A recent report from the CHAdeMO association put the total number of worldwide fast chargers at 2,501 units.
Overall, Navigant Research says the current EV charger market will close-out 2013 at around $713 million in value, but will grow to just under $3.8 billion by the end of this decade.
The study says that “the growth of the EVSE industry is directly tied to the growth and dynamics of the PEV market, PEV owner charging behavior, industry standards, and existing grid infrastructures.”
Navigant says North America is the strongest market for plug-in vehicles, but with a strong emphasis on plug-in hybrid electric vehicles (PHEVs), which has lead to the highest volume of public chargers, but a slower adoption rate of fast charging.
“Because battery electric vehicles (BEVs) have been stronger in Europe and Asia Pacific, these regions have seen greater installations of faster charging EVSE technologies, such as DC fast chargers and battery swap stations.”
