To help prevent the worst consequences of climate change, Japan and more than 100 other nations have pledged to achieve carbon neutrality, or net-zero carbon dioxide emissions. However, Japan lags far behind many European nations in the wide adoption of Battery Electric Vehicles (EV hereinafter), which have been touted as eco-friendly because they do not emit greenhouse gases. To rectify this situation, Project Associate Professor Hiroyuki Baba and Project Research Associate Masaki Imanaka, both of the Institute of Industrial Science, the University of Tokyo (UTokyo-IIS), are developing IoT-based technologies to charge electric vehicles in a more eco-friendly manner by adjusting demand for electricity generated from renewable energy sources.
