We work to develop the next-generation power device technologies that will be key to increasing electric vehicle range and to reducing the size and weight of the PCUs~{*1} used to control power. We have already developed and put into practical use SiC power semiconductors that achieved both longer lifetime, and high voltage/current operations through the realization of an original trench gate structure. Similarly, we have developed device technologies that enable high-precision battery charge and discharge status control using a small number of IC chips. We also actively promote collaborations with Toyota Group companies and academic institutions in aims of further reducing power loss and of improving productivity.
