No sourced single price exists for an eight-charger DC hub. What exists is the DOE-cited U.S. frame for the DC fast class — about $38,000–$90,000 in equipment plus $20,000–$60,000 in installation per unit. Multiplied out across eight units, that frame reads $304,000–$720,000 for equipment and $160,000–$480,000 for installation: arithmetic on a sourced range, not a quote and not a typical figure. A third layer, the utility connection, has no published range at all — only the utility’s written offer prices it.
Key Takeaways
- The only sourced frame is per-unit and U.S.: $38,000–$90,000 equipment plus $20,000–$60,000 installation per DC unit — $304,000–$720,000 and $160,000–$480,000 for eight.
- That multiplication is a budgeting frame, never a quote or a typical hub price.
- The utility connection is a separate, unpriced layer: only the utility’s written offer decides it.
- Compact DC is a different class from corridor DC; an eight-unit hub of either kind is specified and quoted on its own duty.
The Eight-Unit Frame, Layer by Layer
| Layer | The sourced U.S. frame, multiplied out | What your own quotes decide |
|---|---|---|
| Equipment — eight DC units | $38,000–$90,000 per unit, so $304,000–$720,000 for eight | Quotes against a frozen specification: power point, dispensers, connector set, certification for your market |
| Installation and site works | $20,000–$60,000 per unit, so $160,000–$480,000 for eight | Survey-based quotes: switchgear, trenching, foundations, surfacing — shared works do not scale with unit count |
| Utility connection and network work | No published range — deliberately left unpriced here | Only the utility’s written connection offer; carry it as provisional until it lands |
| Programme duties, if the hub is funded | No price — a requirements layer | Under the U.S. NEVI rules, corridor DC ports are 150 kW or more, open 24/7, with contactless payment and average annual uptime above 97% |
The frame brackets the project; it does not price it. The wider class picture in how much commercial EV chargers cost sets this DC band beside Level 2, and the commercial installation cost breakdown walks the site side line by line.
Why Multiplying Is a Frame, Not a Quote
- Equipment multiplies cleanly; installation does not. Eight units are eight equipment lines. But one trench can serve several units, one switchboard can feed the row, one mobilisation covers the site — the installation quotes come from the survey, not from times-eight.
- The power point moves the equipment line. Units at different points in the DOT’s 50–350 kW band are not priced alike, and no source splits the DOE range between them — your frozen specification does.
- The utility layer can outweigh a unit. If the supply cannot carry eight units at full rating, network work becomes the project’s largest and slowest item, priced only in the connection offer.
- Running lines sit outside the capital frame. Software, maintenance after warranty, and energy costs belong in the same budget conversation but in neither DOE range.
The Class Check Before You Budget
An eight-unit hub in this frame is corridor-class procurement: high-power units, a heavy connection, programme duties if funding is involved. Be plain about where EVDANCE sits. Our DC unit, the EV-RHDC30K-L, is a compact charger at 22 kW DC with OCPP 1.6J and IP54 — below the 50–350 kW band, priced as its own smaller lines, and suited to depots and destinations whose dwell is measured in hours. A hub of compact units is a different project, quoted per project, not read off this frame. Where part of a site is long-dwell, AC posts sit in a different cost class again: the EV-AC03201T dual-connector AC station (two Type 2 connectors, up to 43 kW shared, OCPP 1.6J, RFID, IP54) serves two bays per unit. Hub budgets that mix classes can be scoped with our commercial charging team via contact us — bring the unit count and dwell pattern.
Frequently Asked Questions
Can I just multiply the per-unit DC cost by eight?
For equipment, as a budgeting frame, yes — that is what the table does. For installation, only loosely: shared trenching, switchgear and mobilisation mean the survey quotes set the figure, not the multiplication. The utility layer never multiplies; it is one offer for the whole site.
Does the frame include the electricity supply upgrade?
No. No published range covers it. If eight units need network reinforcement, that cost and its timetable exist only in the utility’s written connection offer for your site — request the offer before the budget is frozen.
Would eight smaller DC units cost less than eight corridor-class units?
They are a different class and a different duty: compact DC at 22 kW turns vehicles around more slowly than the 50–350 kW band. Whether that fits your site depends on dwell time; the project is quoted on its own specification, not priced from this frame in either direction.
