Episode notes
Protect Your Range With App Limits
- Use apps and station limits to protect your driving range by stopping discharge at set SOC thresholds (e.g., 20%).
- Check discharge windows and limits before participating to avoid being left without usable charge.
Why V2G Took Decades To Arrive
- V2G stalled earlier because batteries were low-capacity, short-lived, and expensive, and EV adoption was tiny.
- Modern lithium batteries, faster chargers, and more EVs make V2G economically viable now.
Wuxi Pilot Shows Local Impact
- In Wuxi, 30+ cars discharged 1,200 kWh and met daily summer demand for about 150 residents.
- The pilot shows small fleets can meaningfully relieve local peak loads during hot days.
