Charge Now vs Later: A Practical EV Timing Framework
How to decide whether to charge your EV now or wait for a cleaner grid window, using forecasted session averages.
What This Means For Charging
Start with your charging load in kWh and your average home charging rate. Estimate total charge duration before comparing windows.
Practical Note 1
Compare three numbers: best upcoming window, worst window, and charging now. This gives clearer tradeoffs than raw percentages alone.
Practical Note 2
When improvement versus charging now is small, convenience may win. When improvement is large, waiting can meaningfully reduce emissions.
