At present, there are various standards for quick chargers for pure electric vehicles (EVs), including the Japanese-dominated CHAdeMO standard and the European-led Combo2 standard. At the "Europe 28th International Electric Vehicle Symposium and Exhibition" (EVS 28) held at the 3rd to 6th May 2015 International Electro-Mechanical Symposium and Exhibition, Japan's Toko Takayuki exhibited a charging interface to support various methods. Fast Charger (Concept Model) (Figure).

The biggest feature of this fast charger is that it is equipped with two charging units with a maximum output power of 30kW, which can simultaneously charge EVs supporting the CHAdeMO standard and EVs supporting the Combo2 standard. According to the commentator at the scene, some countries and regions are coexisting with two standards. If a quick charger can support two standards, then there is no need to set two quick chargers at the charging station. For charging station operators, both cost savings and space savings can be achieved.

Dongkuk Highy plans to complete the development of the charger by the fall of 2015, starting from the winter of 2015. The price "should be less than 3 million yen" (the commentator). In addition, the narrator also said that a quick charger with a charging interface and a maximum output power of 50 kW is now priced at about 2 million yen.

According to the narrator, in the past, public facilities and other high demand for 50kW fast chargers. However, most EV users will charge when the battery power is about 30%. Therefore, more and more people think that 30kW is enough. Currently, fast chargers such as convenience stores are mainly based on 20 to 30 kW. (Reporter: Tomihiro Miooka, "Nikkei Manufacturing")
