According to an EV Charging Infrastructure report, the global EV Charger (EVC) market is forecast to grow from more than 1 million units in 2014 to more than 12.7 million units in 2020,
There are two main types of plug-in EV charging stations – AC or DC. An AC charging station supplies current to the on-board vehicle charger and typically provides 5-15 miles of electric range per 30 minute charge, while a DC charging station supplies current directly to the vehicle battery and typically provides about 80 miles of electric range per 30 minute charge.
“AC charging stations are the dominant type of plug-in vehicle charging type, and we expect AC charging to retain its position long-term,” said Scott. “AC charging is also an inexpensive and convenient way of charging requiring much smaller upgrades of the electricity grid, whereas DC charging is best suited for ‘en route’ charging.”
IHS Automotive claims that AC charging will play a crucial role in the public domain of the EV charging infrastructure. According to the report, approximately 10 percent of EV charging stations by 2020 will be within the public or semi-public domain, whereas the global DC charging stations are expected to be relatively low and located on the outskirts of cities and highway infrastructure, rather than located in dense urban areas.
The report finds that the deployments of the charging stations are dependent on a highly variable price range. The price can range from $395 USD for a simple domestic wall box to more than $35,000 USD for a DC charging station. This figure does not include installation costs that could add $10,000 in the case of a DC charging station, depending on its location and accessibility.
The report further states,
Japan will be a key growth region for the EV charging stations. In Europe, the Netherlands, the United Kingdom and Norway are leading the way, but Germany and France also have high potential. The slow pace of growth in Germany and France is attributed to underdeveloped EV charging station networks.
In the U.S., EV charging station deployments are primarily driven at the state level. As an example, the ‘greener’ states, like California, deploy more EV charging stations than others,” Scott said. “This is highly dependent on the individual state’s level of incentives and legislation supporting the adoption of EVs, along with regulations for fuel economy.”
Japan has more than 2,800 DC fast charging stations, using CHAdeMO, the Japanese fast-charging standard. Japan accounts for roughly 50 percent of the global total of all CHAdeMO stations, according to the IHS Automotive report.
Europe and North America also have their own fast charging standard, Combined Charger System (CCS). This type of a fast-charging station is supported by the majority of OEMs, such as Audi, BMW, Daimler, Chrysler, Ford, GM, Porsche, and Volkswagen. Vehicles with fast DC charging capability based on the CCS standard have only been on the road since 2013.
From 2010 to 2014, IHS forecasts that just seven percent of electric vehicles globally use the CCS charging system and about 65 percent use the CHAdeMO standard. IHS expects this will change over the short to mid-term, as more vehicles with the CCS standard enter the vehicle parc (vehicles on the road). There will gradually be a more even split between the two DC fast-charging standards.
