Why You Can’t Install a DC Fast Charger at Home

• Power Requirements: DC fast chargers pull huge amounts of power (50 kW to 350 kW+), far beyond what typical home electrical systems can handle.

• Infrastructure: Homes usually lack three-phase power and industrial-grade transformers needed for DC fast charging.

• Cost: DC fast chargers themselves cost tens of thousands of dollars plus costly upgrades and permits.

• Safety & Regulations: High voltage and current require strict safety standards and trained personnel—typically only feasible in commercial settings.

Best Home Charging Solution: Level 2 AC Chargers

• Use 240V power, commonly available or easily installed in homes.

• Provide up to ~25-30 miles of range per hour — enough to recharge overnight for most daily driving.

• Affordable equipment ($500–$2,000) and installation ($1,000–$2,000).

• Compatible with almost all EVs on the market.

• Often eligible for utility rebates or incentives.

What About Portable DC Chargers?

• Mostly experimental or emergency use.

• Very expensive, limited battery capacity.

• Not practical for daily use yet.

Future Outlook

• Emerging technologies (solid-state batteries, better grid integration, home solar + storage) could one day make home DC fast charging more feasible.

• For now, Level 2 chargers are the sweet spot for home EV charging.
