Mitsubishi Electric Corporation has announced that it has developed a technology for efficiently managing photovoltaic (PV) and other power-generation systems and also the charging/discharging of electric vehicles (EVs) parked on company campuses. By optimising the schedules for not only charging EVs but also discharging their power back into the company, as well as optimising the operation of PV and other power-generation systems according to the fluctuating unit price of electricity sold on the grid, Mitsubishi Electric's new system enables companies to reduce their electric-power costs.
