    • Expand the product lineup of EV/PHEV chargers (quick chargers and AC chargers) and broaden sales to a wide range of customers.
    • Promote the development of power conversion devices that alter the charging and discharging cycles of batteries to ensure stable electrical supply and energy saving.
  • 3. Focusing resources on product groups that can reduce greenhouse gas emissions
    • The Energy Systems & Solutions Division considers its mission to be efficiently contributing to the creation of various energy sources in a manner that ensures the safe and secure use of energy. The division contributes to efficient energy use through the development of power-conversion-related efficiency technology and will work to further expand its eco-friendly products going forward.


1. Earnings structure construction

We began new development of 600 A rectifiers. We are advancing product development leveraging our accumulated technologies and expertise.

2. Building a foundation for expansion of growth businesses

We developed 150 kW quick chargers compatible with the Open Charge Point Protocol (OCPP) as well as 6 kW AC chargers and released them as products. We will continue sales expansion activities in order to gain market share throughout the EV charging market.

We developed bidirectional energy converters to meet the needs of the growing renewable energy market. Going forward, we will advance development toward product launch.

3. Focusing resources on product groups that can reduce greenhouse gas emissions

We advanced technological development of electric power converter components (200 A units) for power sources used in the telecommunications market, improving efficiency by approximately 5% and reducing loss by 58%.
