Common questions
- Why is public charging so much more expensive?
- Networks price for convenience, demand, and infrastructure cost. DC fast charging also includes higher equipment and demand charges passed to drivers.
- Should condo buyers assume 100% public?
- If you lack assigned Level 2, model public-heavy scenarios before buying a full EV. Many buyers land on PHEV or hybrid instead.
- Is this financial advice?
- No. Informational estimates only. Rates vary by state, utility, and charging network.
