There is no single best setup, but for a driver who earns by the mile the winning shape is consistent: a Level 2 charger at home, sized to refill your real working day inside your real overnight window, with public DC kept as an exception tool for overrun days. Size it from your own miles — that calculation decides almost everything else.
Key Takeaways
- The setup is home Level 2 sized to your nightly miles, plus public DC kept as a bought-time exception.
- Do the window maths with your own miles and consumption before choosing between 32 A, 40 A and 48 A.
- Every shift starting full, at residential prices, is the working driver’s margin.
- Renters without home charging run a different, public-priced business — judge the car on those numbers.
Why the Home Charger Is the Business Asset
A working driver’s fuel supply is part of the business. Home charging wins on both sides of the ledger. Price: U.S. residential electricity averages 18.31 cents per kWh, well below public prices. Time: the car charges while the driver sleeps, so every shift starts full and no working hour is spent at a plug, as our guide to charging versus gasoline costs shows.
Size It From Your Nightly Miles
Level 2 adds roughly 10–20 miles of range per hour on U.S. DOT figures. Worked with example numbers:
- An example driver covers 200 miles a day and parks 8 hours overnight. At an example 0.30 kWh per mile — your car’s figure is in its own documents — the day uses about 60 kWh.
- The window maths: replacing 60 kWh in 8 hours needs about 7.5 kW on average before losses — inside the Level 2 band, but above a small portable’s output. A 9.6–11.5 kW charger (40–48 A) covers it with margin; a 32 A unit leaves the plan dependent on a top-up.
- Change the inputs, keep the method. A 120-mile day on the same consumption needs about 36 kWh — a 32–40 A charger replaces it comfortably.
| Your nightly miles | The setup that fits |
|---|---|
| Up to about 120 miles | A 32–40 A Level 2 charger, portable or wall-mounted |
| About 120–200 miles | A 40–48 A wallbox, so the whole day refills inside the window |
| Over 200 miles, or a short overnight window | The 48 A wallbox plus a planned DC top-up on the longest days |
Public DC Is the Exception Tool
Keep DC in the plan, but price it honestly: you are buying time, at public per-kWh prices, because the day overran — a double shift, a late start. Used that way it protects earnings; as the daily supply it gives back both advantages, for the reasons in why public charging costs more than home electricity. The question is never “home or public” — it is how small you can keep the public share.
If You Rent and Cannot Fit a Home Charger
The alternative exists, but it is a different business. Drivers without home charging build the week around the public network near home — a slow charge where one is available, DC top-ups inside breaks — and run the numbers at public prices, not residential ones, before committing. Some landlords and workplaces allow a portable unit on an existing suitable outlet; permission, and the outlet’s fitness for a continuous load, are the landlord’s and an electrician’s calls. If neither route exists, judge the car without the home-charging margin.
Two EVDANCE Options That Fit the Two Situations
For the owned-home case, the EV-ACT5006T is a 48 A wall charger (hard-wired or NEMA 14-50P, NACS, 25 ft, IP65/IP66) — the top of the home band, sized for the 200-mile example. Where parking or tenancy favours a portable, the EV-ACS4005T is a 40 A NACS portable (9.6 kW, NEMA 14-50P, 16/24/32/40 A adjustable, IP66, 25 or 28 ft) that also travels as a backup. Both carry the 3-year standard warranty.
Frequently Asked Questions
Should a working driver install DC fast charging at home?
No. DC fast charging is depot and public infrastructure — DOE figures put its equipment and installation in the tens of thousands of dollars — and overnight Level 2 already refills a working day inside the parking window.
Is 40 A enough, or do I need 48 A?
Run the window maths with your miles and your car’s consumption. If overnight hours × charger rate covers your daily energy with margin, 40 A is enough; high-mileage drivers with short windows use the 48 A headroom.
Does the car limit the setup?
Yes — the car’s onboard charger caps the AC rate it accepts, whatever the wallbox offers; its documents state the figure. Match the charger to the car you run, not the largest number on sale.
