Utility-led V2G Limits Consumer Use
- Vehicle-to-grid (V2G) by utilities is complicated and primarily designed to maximize their profits.
- These systems limit consumers from using their EV batteries to save on peak electricity costs and are rarely cost-effective.
Barry's Ford Lightning V2G Experience
- Barry Cinnamon started a V2G project with a Ford Lightning truck which has a large 131 kWh battery.
- He found V2G integration systems sponsored by car companies to be unreliable and difficult to install.
V2G Systems Need Complex Integration
- V2G systems require complex hardware including bi-directional chargers, grid-compliant inverters, gateways, and a black start battery.
- Extensive software and firmware integration is required, which is a major obstacle to reliable V2G operation.
