Level 1
- Daily mileage is modest
- Long overnight dwell time is available
- A suitable dedicated outlet is confirmed
US SYSTEM COMPARISON
Level 1 vs. Level 2 home EV charging
Start with daily miles and overnight dwell time before paying for maximum charging power.
| Decision | Level 1 | Level 2 |
|---|---|---|
| Supply | 120V outlet | Dedicated 240V circuit |
| Charging pace | Lower | Higher |
| Electrical work | May use a suitable existing circuit | Load calculation, circuit and permit commonly required |
| Best sizing input | Daily energy needed | Vehicle, dwell time and service capacity |
| Quote focus | Outlet and circuit condition | Amperage, wiring route and load management |
Fit check
When each route deserves a closer look
Level 2
- Daily energy need is higher
- Faster recovery between trips matters
- Panel capacity or load management is documented
Comparison questions
Keep the assumptions equal.
Is Level 1 always cheaper than Level 2?+
No. Equipment, existing infrastructure, local labor, permits, financing and operating cost must be compared with the same home assumptions.
How should I compare Level 1 and Level 2 quotes?+
Give bidders the same home data and require itemized equipment, labor, electrical or fuel work, permits, commissioning, exclusions and warranties.
