No. 126: Electric vehicle battery charger is also an important factor for smart house (April 26, 2012)

Business trend of the smart house market (7/8)
Electric vehicle battery charger
With the spread of EVs and PHVs, the market of electric vehicle battery charger has been increasingly rapidly. The market increased more than two times from about 4 billion yen in 2010 to 8.4 billion in 2011. It is expected to increase 54 times from the level in 2010 to more than 200 billion yen in 2020. The traffic infrastructure market that includes electronic toll collection system (ETC), beacon, dedicated short-range communication system (DSRC), vehicle detection center, electronic information bulletin board, battery charger, non-contact charging system, and battery exchange center will increase 3.6 times from 18 billion yen in 2010 to 62 billion yen in 2020 in Japan, and increase 7.4 times from 62 billion yen in 2010 to 460 billion yen in 2020 in the world.

In order to spread electric vehicle battery chargers among household, it may be necessary to introduce a subsidy system in addition to reducing production cost with a view to reducing the price from the current several hundreds of thousand yen to less than 100,000 yen. At the same time, it is necessary to make the unit smaller, improve designability, and improve user-friendliness. As for quick charger, installation cost is inevitably higher because power receiving equipment and high-voltage conductor are vital to get such a high output of 50 kW. In the future, the industry will construct a system to reduce the cost for rapid charging by a system to apply renewable energy and incorporate the storage function in the rapid charger.
