An EV charger tender specification usually tests five things: performance, interoperability, driver access and payment, service and uptime, and the evidence behind every claim. The numbers change with the buyer and the funding behind the project; the categories do not. Read by category first, and answer each line only with evidence you hold.
Key Takeaways
- Specifications test five categories: performance, interoperability, access and payment, service and uptime, and evidence.
- Funded specifications turn categories into numbers — NEVI is the clearest example — and each buyer’s numbers are their own.
- Answer every line from the exact model’s file; “OCPP-ready” is never upgraded into a compliance claim.
- A compact DC unit is bid at its stated scale, never as a NEVI-class charger.
The Five Categories in Almost Every Specification
| Category | What the buyer is really testing | Evidence that answers it | The trap |
|---|---|---|---|
| Performance | The unit delivers its stated power on the site’s supply | Nameplate ratings and the datasheet for the exact model | Quoting a product family’s top figures for the unit actually bid |
| Interoperability | The charger runs on the platform the buyer has chosen | The protocol version stated on the model’s own listing and file | Reading “OCPP-ready” as if it meant OCPP-compliant |
| Access and payment | Any driver can start a session and pay | Stated access features such as RFID; payment as written scope | Implying a touch screen is a payment terminal when it is not one |
| Service and uptime | Someone keeps the chargers running over the contract | Written service terms, warranty text, a spares route | Promising an uptime figure with no service system behind it |
| Evidence and compliance | Every claim in the bid can be checked | Certificates and declarations for the exact model and configuration | A document file written for a different variant of the model |
The interoperability row deserves care: the difference between a stated protocol version and a “ready” phrase is the difference between evidence and hope — our explainer on OCPP for charge point operators shows why. The compliance row works the same way: marks are claims, and the file behind them is the answer, as our guide to EV charger certifications explains.
The Clearest Worked Example: A Funded Specification
Specifications attached to public money show the categories converted into numbers. Under the U.S. NEVI rules in 23 CFR Part 680, corridor DC ports must deliver at least 150 kW, stations must open 24/7, average annual uptime must exceed 97%, payment must be contactless with no membership required, and DC ports use CCS1 connectors. Each line is one of the five categories with a figure attached. Most local tenders are not NEVI tenders and their figures differ — never carry one buyer’s numbers into another buyer’s bid.
Reading a Specification Before You Price It
- Separate pass/fail lines from scored lines. The documents tell you which are which; a failed mandatory line usually ends the bid.
- Flag what your file cannot evidence. Raise it through the clarification route the documents give, before submission — not after award.
- Check the configuration traps. Cable or socket version, connector variant, phases: the file must match the unit tendered.
- Price the whole scope. Specifications often bundle installation and service years with hardware — see our breakdown of commercial installation costs.
Where EVDANCE Models Sit Against These Categories
Answered strictly from the published listings: 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 and IP54 — so its interoperability answer is a stated version, not a phrase. The EV-ACS3210E’s listing says “OCPP-ready”: that wording must stay exactly as stated, because it is not a claim of OCPP 1.6J compliance, and presenting it as one would be a false claim. The EV-RHDC30K-L is a compact DC unit at 22 kW DC with OCPP 1.6J and IP54: right for specifications written at that scale, never to be bid as a 150 kW NEVI-class unit. EVDANCE is a Shenzhen manufacturer founded in 2011, exports to more than 30 countries and offers a 3-year standard warranty; tender document requests go through the commercial charging team or contact us.
Frequently Asked Questions
Do all buyers require the same things?
No. The categories repeat, but the figures, evidence format and mandatory lines are set by each buyer’s documents and funding. Read every specification fresh.
What if our charger nearly meets a line?
Answer what the model’s file states, and use the clarification route if the line is essential. An overclaim discovered at delivery becomes a contract problem.
Is “OCPP-ready” the same as OCPP compliant?
No. “Ready” is a listing phrase about preparation. A compliance answer needs the protocol version stated for that exact model, backed by its document file. Quote the listing’s wording, never an upgrade of it.
