  • Toshiba has developed a 7-kW contactless charger for electric vehicles (EVs) that meets the requirement for a wider range of car types (April 2014) It is a bother to plug and unplug the connector of a conventional wired charger for plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs). To address this problem, Toshiba has developed an easy-to-use and safe contactless EV charger. The new contactless charger can transmit electric power over a distance of 17 cm, accommodating the requirement for high-bodied minivans. The charger has been tested in combination with a battery controller mounted on an electric vehicle. The test has verified that the charger has a capacity of 7 kW. Thus, it will halve the charging time, compared to 3-kW-class wired on-board chargers that are most widely used in Japan. The permissible right-left misalignment between the transmitting and receiving pads is up to 25 cm. This will ease the strain on drivers for parking accurately, compared to comparable chargers from other vendors that tolerate a misalignment of only up to 15 cm.
