Toyota announced the Camry Hybrid SiC prototype, the new Camry hybrid concept that makes use of a new semiconductor technology prepared in collaboration with Denso.

The semiconductors are made of silicon carbide (SiC) and because of this they “significantly reduce” the power loss in hybrid cars, increasing the fuel economy by 10%. Semiconductors play an important role in hybrid systems and they are located in the power control unit (PCU), which oversees the flow of electricity from the battery to the motor and sends electricity recovered from braking and deceleration on the battery for storage. However, the PCU is responsible for 25% of the lost electricity in hybrid cars, with 20% being lost due to the semiconductors.

Testing of the prototype will begin within the next month, with Toyota to collect data and comparing it with other models equipped with traditional silicon semiconductors, to assess the improvements that are achieved by semiconductors made of silicon carbide. If all goes well, we expect implementation of this new technology in future hybrid and electric vehicles of the company.
