Start with energy needed overnight
Maximum charger power is not always necessary. Daily mileage, vehicle efficiency and parking duration determine the useful charging target.
Check the vehicle's onboard charging limit before paying for unused capacity.
Require an electrical load calculation
The contractor should evaluate service and panel capacity, conductor route, breaker, disconnect requirements and permit process.
Load management can be compared with a service upgrade when capacity is constrained.
Plan for rates and future loads
Compare utility time-of-use and managed-charging programs, including enrollment and control terms.
Consider a second EV, solar, storage, heat pumps and electric water heating in the home's longer-term electrical plan.
