Solar-EV-Charging aims at integrating Electric Vehicles (EVs) to enhance the deployment of Photovoltaic (PV) systems in tropical Singapore. Leveraging a large-scale GPS-based mobile phone dataset, EV mobility patterns across Singapore are predicted, with detailed views zooming into specific communities. Aligning with localized PV energy potentials, EVs can thus be optimally used as time and spatially dynamic batteries.

The tropical climate in Singapore presents a unique challenge for renewable energy integration due to its highly variable weather conditions, including frequent thunderstorms and rapid cloud movement, which result in fluctuating PV output. In response to this challenge, the Mobility WP explores the integration of EVs with PV energy to enhance grid stability. EVs are charged using renewable energy from PV systems and act as mobile energy storage units that can discharge electricity back into the grid using Vehicle-to-Grid (V2G) technology. This bidirectional energy flow is crucial for flattening the inherent fluctuations in PV generation, particularly during periods of variable sunlight. The demo showcases how this dynamic system can mitigate the adverse effects of these fluctuations, improving the overall power quality and ensuring a more stable energy supply.
