Home EV Charging Guide 2026: Level 2 Installation & Costs
If you own an electric vehicle in Chicago, home charging is essential. Public chargers are growing but unreliable during Chicago's sub-zero winters when battery range already drops 20-40%. A Level 2 home charger adds 25-40 miles of range per hour — overnight charging gives you a full battery every morning. Here's everything you need to know about installation, costs, and the best chargers for 2026.

| Installation cost | $0 (uses standard outlet) | $500-$2,000 |
| Equipment cost | Included with car | $400-$800 |

Installation in Chicago

- Dedicated 240V circuit: $500-$1,500 depending on distance from panel to garage
- Charger mounting and wiring: $200-$500
- Permit fees: $75-$150 in Chicago proper
