Smart charging is highly effective in reducing carbon emissions from electric vehicles (EVs). By optimizing charging times to align with periods when renewable energy sources are abundant on the grid, smart charging can significantly decrease the carbon footprint of EVs. Here’s a summary of its effectiveness:
- Emissions Reductions: Studies indicate that smart charging can reduce annual carbon emissions by up to 18% compared to baseline charging methods. Daily emissions can be reduced even more significantly, by up to 90% on certain days, particularly during periods of high renewable energy availability.
- Carbon Savings: Utilizing smart charging can save around 140 kg of carbon emissions annually, equivalent to the carbon sequestered by several trees. Another study found that smart charging could reduce emissions by around 152 kg annually in unconstrained scenarios and 64 kg in constrained ones.
- Environmental Benefits: Even in regions with mixed grids (fossil and renewable sources), smart charging can maximize emissions reductions by synchronizing charging with renewable energy generation periods. For example, charging during windy nights in regions rich in wind power or during sunny days in areas with abundant solar energy can significantly reduce emissions.
Overall, smart charging is a powerful tool for decarbonizing transportation by optimizing when EVs charge to reduce their reliance on fossil-fuel-generated electricity.
