Toyota Develops Chips for Hybrid Cars to Boost Fuel Efficiency

Tuesday, 20 May 2014 10:28 AM

Toyota Motor Corp. has developed a computer chip for its gas-electric hybrid cars that could boost fuel efficiency by 10 percent and allow the automaker to install the hybrid system on more of its vehicles.

The maker of Prius hybrids and auto parts maker Denso Corp. have jointly developed a semiconductor using a silicon and carbon compound that limits power loss and allows for a smaller hybrid system, Toyota said on Tuesday.

"A key way to improve fuel efficiency is to improve power semiconductor efficiency," Kimimori Hamada, a Toyota engineer, told a media briefing.

Toyota's push in semiconductors highlights how carmakers' competitiveness is increasingly tied to electronics rather than to traditional mechanical engineering.

It also reveals the scope for further improvements in gas-electric hybrid technology nearly two decades after Toyota led the market with the launch of the Prius in 1997.

The new chip's silicon carbide compound is already used in computer chips in trains and air conditioners, but this is its first use in automobile power chips, Toyota said.

The battery of a hybrid vehicle captures energy from braking that can aid the combustion engine and improve mileage. The Power Control Unit supplies electrical power from the battery to the motor when the car is running and charges the battery when the vehicle is braking.
