The proposed infrastructure bill includes adding EV charging. Unfortunately, there are risks such as requiring one type of fast DC charger plug, CCS-1. About 79% of all EVs are Teslas so a CCS-1 mandate means only 21%, about 1-in-5 new EVs. But there are subsidies that could work:
- bi-directional grid buffer - so the fast DC charging stations won't sag and can help buffer the grid.
- peak rate above 1,000 kW - urban delivery and service vehicles need a way to 'top off' without having to drive back to their depot.
- mix of J1773 and fast DC charging - parking lot lights should have access with managed rates for grid load mitigation.
- density mitigation - spread the EV chargers to match the density and need. For example, truck stops need to handle cross country and semi-trailer truck charging.
- mix Tesla, CCS-1, and CHAdeMO with counts based on measure usage. Multi-mode chargers get a maximum subsidy while single standard get little to none.
- anti-idle or parking abuse - some way to free the parking spots for those needing a charge. For example, bright or colored parking lane light when not charging. When charging, dim the lane light with a color change to yellow to identify the vehicle should move.
