TOKYO -- Toray Industries has developed a plastic film for capacitors that withstands high voltages, enabling electric vehicles to be charged in 20 to 30 minutes, about half the time currently needed, company officials said. It is expected to accelerate the spread of electric vehicles.
Toray has begun proposing the film, which is designed for vehicles' power control units and can resist 800 volts, to client manufacturers. At present, 400-volt batteries and charging facilities are standard for electric vehicles, and charging takes about 40 to 50 minutes.
