Toyota sets 10% fuel efficiency improvement target for hybrid vehicles

Toyota will introduce new power semiconductor technology to improve fuel efficiency in its hybrid and electric vehicles. The manufacturer has set itself a target of a 10% improvement in efficiency – as calculated according to the JC08 test cycle.

With semiconductors playing an important role in hybrid systems – governing the flow of electricity from the battery to the motor, and sending electricity generated under braking and deceleration to the battery for storage – any electrical loss is keenly felt. Semiconductors account for around 20% of the energy loss in hybrid vehicles – the power control unit (PCU), which houses the semiconductors, makes up 25% of total loss.
Using a new silicon carbide compound for the power semiconductors not only curbs energy loss, but also allows for the PCU to be reduced in size by approximately 80%.


The technology, developed in-house by Toyota in partnership with Denso, is scheduled for public road trials within the year. Toyota is conducting research in a dedicated clean room facility in its Hirose plant, with initial results from prototype models suggest an improvement of greater than 5%. Toyota will be showcasing the technology at the 2014 Automotive Engineering Exposition in Yokohama this week.
