Home Charging Installation: Complete Guide

Installing a home charger is one of the best investments you'll make as an EV owner. This guide walks you through everything: costs, electrical requirements, choosing equipment, and finding installers.

⚠️ SAFETY FIRST: Home charging installation involves high-voltage electrical work. Always hire a licensed electrician and consult your vehicle's owner's manual for specific requirements. Improper installation can result in fire, electric shock, or damage to your vehicle.

Why Install a Home Charger?

The reality: Most EV charging happens at home (80%+ of all charging). A Level 2 home charger transforms your EV ownership experience from "planning around public chargers" to "wake up with a full battery every morning."

Benefits:

Convenience: Plug in at night, wake up fully charged
Cost: Home electricity is 2-4x cheaper than public DC fast charging
Time: Overnight charging while you sleep
Battery health: Slower Level 2 charging is gentler on the battery than repeated DC fast charging

Can I Just Use a Regular Outlet?

Yes, but… your EV comes with a Level 1 charging cable that plugs into a standard 120V outlet.

The problem:

Level 1 charges at 3-5 miles of range per hour
To fully charge a 60 kWh battery: 40-50 hours
For daily driving (40 miles): 8-12 hours overnight works
For longer commutes or road trip prep: Painfully slow

When Level 1 is sufficient:

Very short daily commute (<30 miles)
Access to workplace charging
Plug-in hybrid (PHEV) with small battery

For most BEV owners: Level 2 installation is essential.

Level 2 Home Charging Explained

What it is: 240-volt charging (same as your electric dryer/oven)

Charging speed: 25-40 miles of range per hour (depending on charger power and vehicle)

Full charge time: 4-10 hours for most EVs

Example:

2026 Subaru Solterra (72.8 kWh battery)
With 7.2 kW charger (30A circuit)
0-100% charge: ~10 hours
Perfect for overnight charging

Electrical Requirements

Understanding Your Electrical Panel

Typical home service:

100 Amp (older homes)
150 Amp (common)
200 Amp (newer/larger homes)

Load calculation: Each circuit in your panel draws a certain amount. Adding a 40-amp or 50-amp EV charger circuit requires available capacity.

When you need a panel upgrade:

Total home load + EV charger exceeds panel capacity
No physical space for additional breaker
Panel is outdated/unsafe

Cost of panel upgrade: $1,500-$4,000

Circuit Sizing

Common charger power levels:

| Charger Power | Circuit Size | Breaker | Typical Range/Hour | |---------------|--------------|---------|---------------------| | 3.8 kW | 20A / 240V | 20A | 12-15 mi/hr | | 7.7 kW | 40A / 240V | 40A | 25-30 mi/hr | | 9.6 kW | 50A / 240V | 50A | 30-37 mi/hr | | 11.5 kW | 60A / 240V | 60A | 35-44 mi/hr |

Most popular: 40A circuit (7.7 kW charger)

Works for 95% of EV owners
Charges typical EV (60-80 kWh) overnight
Doesn't overload most panels

Pro tip: Match charger to your vehicle's max AC charging rate

2026 Subaru Solterra: 6.6 kW max → 32A circuit sufficient
Tesla Model 3/Y: 11 kW max → 48-60A circuit ideal
Check your vehicle's specs before buying charger
