Pick the charger, measure the run and confirm the panel has capacity before buying anything.
A Level 2 charger installed with a 30 ft run typically costs $1,600 to $2,200 nationally, with a range of $900 to $2,500. A panel upgrade adds roughly $1,800 to $4,500.
Only if the load calculation shows no spare capacity. Many 200 A panels can carry a 40 A charger; older 100 A panels often cannot, and load management devices can avoid an upgrade.
About $12 to $22 per foot installed, depending on wire size and whether it runs through conduit, attic or a detached garage.
Forty amps adds about 30 miles of range per hour and suits most drivers. Forty-eight amps adds more but needs a hardwired 60 A circuit and a panel that can support it.
In most US jurisdictions, no. It is a permitted electrical circuit, and DIY work can void insurance and fail inspection. Some states allow a homeowner permit but require inspection.
Utility rebates and state programs change often. Ask your utility for current offers, and keep the invoice, permit and charger model number for the claim.
