The future of electric vehicles continues to elude scientists as they attempt to devise promising and practical ideas to keep these cars moving along the highways without having to pull over and wait for a battery recharge. Solutions for the charging and range of electric vehicles took a giant leap forward when a Japanese university team demonstrated how electricity can be transmitted to a pair of tires through a four-inch-thick block of concrete, the type of concrete used on roads.
Their solution is in the form of a wireless power prototype that can successfully transmit electricity through the concrete block. They consider the prototype as an early step to improve on, and that such an approach can be used one day to keep electric vehicles on the move.
Takashi Ohira, an electrical engineering professor at the Toyohashi University of Technology, who leads the team, has developed his electric field coupling system to supply a charge to a car through its tires. The goal is to enable power transmission as the vehicle’s tires travel along the road with suitable efficiency and power transfers.
To make their present technology useful, the electric power needs to be increased by 100 times. But, moving ahead, the group said that they are up to the task of meeting the project’s challenges.
