How can EV charging support renewable energy?
Smart EV charging can help make better use of renewable electricity by shifting charging to times when renewable generation is more readily available.
Wind and solar generation vary with weather conditions, while electricity demand changes throughout the day. Flexible charging helps align these two patterns where vehicle schedules and energy-system conditions allow.
How does it work?
Imagine a fleet of electric vehicles plugged in during the afternoon when solar generation is high. If the vehicles do not need to be fully charged immediately, a smart charging system may bring forward some charging to use that available electricity.
Charging can also be shifted away from periods when renewable generation is lower and demand is high, depending on the system and tariff.
This does not mean every EV automatically charges on renewable electricity. The outcome depends on the electricity mix, charging controls and timing.
What are the benefits?
- Better alignment of demand and generation: Shift flexible charging towards periods of abundant renewable electricity.
- Grid flexibility: Adjust charging to help respond to changing electricity-system needs.
- Potential cost benefits: Some tariffs may reward charging during lower-priced periods.
- Efficient energy use: Coordinate charging around vehicle requirements rather than using a fixed schedule for every vehicle.
These benefits depend on local conditions and the charging system.
