“Charging machine” prices split by class, not by the word on the listing. An AC post prices inside the Level 2 frame — DOE-cited U.S. figures, about $3,500 equipment plus $2,500 installation per connector — while a DC cabinet sits inside the DC fast frame of about $38,000–$90,000 equipment plus $20,000–$60,000 installation per unit. The gap is structural, not branding: an AC post hands AC to the car’s own converter; a DC cabinet carries the conversion hardware itself. Compare within a class only.
Key Takeaways
- AC posts and DC cabinets price in different DOE-cited frames because conversion happens in the car, or in the cabinet.
- Count AC per connector, DC per unit; mixing units corrupts comparisons.
- Compact DC at 22 kW sits below the DC fast band; the cabinet frame does not price it.
- Utility work, civil works and platform services sit outside equipment prices.
What Structurally Separates the Classes
Five dimensions explain nearly all of the price distance between the classes.
| Dimension | AC post | DC cabinet | The sourced frame |
|---|---|---|---|
| Where conversion happens | In the car — the vehicle’s onboard charger does the conversion | Inside the cabinet — power electronics convert AC to DC before the connector | U.S. DOT bands: Level 2 at 7–19 kW; DC fast at 50–350 kW |
| Power electronics content | Control, protection, metering and access around a pass-through supply | The conversion stage itself, sized to the rating | DC equipment frame: about $38,000–$90,000 per unit (DOE-cited, U.S.) |
| Cooling | Heat loads of control electronics at AC power levels | Conversion heat must be engineered out of an enclosed cabinet | Part of why the DC installation frame runs about $20,000–$60,000 per unit |
| Grid demand | Level 2 loads many existing supplies can carry | A serious connection; the utility’s written offer prices it | No published figure — site-specific |
| Counting unit | Per connector — a dual-connector post is two connectors on one post | Per unit — one cabinet, whatever its connector count | Level 2 per connector; DC per unit — mixing them corrupts the comparison |
Access follows the same split: an AC post states its own access hardware (RFID or app where listed), while DC sessions are typically platform-run. Funded corridor programmes add duties of their own — NEVI requires DC ports of at least 150 kW, 24/7 operation and contactless payment — and those duties are part of what a corridor cabinet’s price carries.
The Two EVDANCE Reference Points
The EV-AC03201T is a floor-standing dual-connector AC station: two Type 2 connectors, up to 43 kW shared (22 kW per connector), OCPP 1.6J, RFID, IP54. Count it as two connectors against the Level 2 frame; its touchscreen is a display, not a payment terminal. On the DC side, class honesty matters: the EV-RHDC30K-L is a compact DC charger at 22 kW DC (OCPP 1.6J, IP54), below the DOT’s 50–350 kW band. The cabinet frame does not price it — it is quoted on its own, smaller lines, and its listing does not name the DC connector variant, a written confirmation before ordering. AC wallboxes such as the EV-ACT5006T sit at the AC class’s smaller end; site quotes run through our commercial charging team or contact us.
Reading a “Machine Price” Listing
- Identify the class first. Class decides the frame, the counting unit and the installation scale before any number is read.
- Check the scope behind the number. Equipment-only and installed prices measure different things; installation rivals equipment in the DOE frames.
- Normalise the counting unit. Per connector, per post and per site are three prices wearing one label.
- Check the rating against the band. A unit below 50 kW DC is not in the DC fast frame, however the listing words it.
- Ask what the price excludes. Utility work, civil works and platform services sit outside equipment prices, as our commercial charger cost guide sets out.
Frequently Asked Questions
Why does a DC cabinet cost so much more than an AC post?
Because the conversion hardware lives in the cabinet. An AC post is control, protection and access around a supply the car converts; a cabinet carries the power electronics, their cooling, and a heavier grid connection. The frames show the scale: thousands per connector for AC, tens of thousands per unit for DC.
Is a compact 22 kW DC charger priced like a DC cabinet?
No. It does the same job at a fraction of the rating, below the 50–350 kW class the frame describes, and is quoted on its own smaller lines — not read off the cabinet range in either direction.
Which class is better value?
Value is a site question, not a class ranking. A cabinet needs vehicles that stop briefly and accept DC; a post serves longer stays far more cheaply per connector. Your site’s dwell and duty decide which pays.
