With the increasing popularity of electric vehicles, supply and demand coordination is necessary to utilise solar-generated electricity for recharging during the daytime, as traffic on highways is concentrated in the morning and evening. In this study, a multi-agent simulation was used to estimate the effect of improving the self-consumption rate when dynamic pricing was introduced for recharging charges, assuming the installation of solar power in service areas.

Development of a New BEV Charging and Power Supply System

The spread of BEVs requires improvements in convenience during charging and power supply, as well as the creation of new value. The new BEV adopts a Plug&Charge system, eliminating the hassle when charging. Additionally, leveraging the advantage of a movable battery, we developed a power supply system that allows the charged electricity to be supplied externally, enabling users to enjoy electricity anywhere without being limited by location.

Study on the Feasibility of Small, Low-Speed EVs with On-Board PV Systems

A research EV with a photovoltaic (PV) system was constructed and road tests were conducted to clarify the feasibility. A PV panel was installed on the roof of a small-size, lightweight, two-seater vehicle, and EV electric consumption, solar irradiance, and PV power generation were measured and analyzed. A simulation model was developed to estimate the effects of installing PV, such as reduction in electric consumption depending on driving conditions and weather conditions.
