The 44th TOKYO MOTOR SHOW 2015

The Sumitomo Electric Group will participate in the 44th Tokyo Motor Show 2015, where participating companies will exhibit new vehicle-related technologies and products. The theme of the Motor Show is “Your heart will race.”

At the Show, we will showcase a variety of automotive technologies, which are categorized into: “For Earth-Friendly Vehicles,” “Connecting Technology Brings No Traffic Jam and Accident in City,” and “Become More Convenient,” under the concept of “Link to the NEXT.”

A demonstration car will be exhibited at our booth. Visitors will be able to see how our automotive products make up an automobile. Using video, we will also explain the products displayed at our booth.

We extend a sincere welcome to you at our booth.

Explanation of the exhibits

Demonstration car

A car made up of the wire harnesses and other automotive products we make will be exhibited. Visitors will be able to visually check the installation position of each product and the three-dimensional routes of the wire harnesses.

More earth-conscious vehicles

Regenerative DC/DC converter

This converter is an energy recovery system that enhances the fuel economy of the vehicle. In particular, this converter controls the voltage between the battery, generator, and each unit to ensure their stable operation. Comprising our original high heat-dissipation board, this converter is compact and highly efficient.

Aluminum harness
A wire harness made of aluminum instead of heavier copper. Use of extremely lightweight aluminum harnesses enhances the fuel efficiency of the vehicle.
