When a charger fails under warranty, the remedy model — not the year count — decides the downtime. Under advance replacement, a substitute unit or part ships on the claim, and the failed one is returned by a set deadline. Under repair-first, the unit is diagnosed first, and the remedy follows the finding. Neither model can be read off a term like “3 years”; the policy or the supply contract names it. Funded corridor stations show why swap models exist: the U.S. NEVI rules require average annual uptime above 97% — a programme obligation on funded sites, not a term any maker owes by default.
Key Takeaways
- The remedy model, not the warranty’s year count, decides downtime after a failure.
- Advance replacement trades on swap stock and a return deadline; repair-first trades on diagnosis quality.
- NEVI’s uptime above 97% is a funded-programme duty — context for swap models, never a maker’s default term.
- EVDANCE publishes a 3-year warranty but no remedy model: confirm the model for your order in writing before signing.
The Two Models, Dimension by Dimension
| Dimension | Advance replacement | Repair-first | The contract line that pins it |
|---|---|---|---|
| Downtime shape | The site is restored when the advance unit lands and is fitted | The site waits through diagnosis, then the repair or replacement leg | The clocks, in writing: ship time, response time, completion time |
| Who holds stock | The maker or distributor holds swap stock of units or named parts | The repair route holds parts and bench capacity instead | Where the stock sits, whose it is, and for which models |
| Evidence demanded | Claim evidence up front — serial, fault record — failed unit returned by a deadline | Diagnosis evidence first; the remedy follows what the diagnosis finds | The evidence pack each model requires, and the return deadline for swaps |
| Freight | Two legs: the advance shipment out, the failed unit back | Legs to and from the repair point, or an engineer’s visit instead | Who pays each leg — and what a missed return deadline costs |
| No-fault-found risk | The maker carries it: a swapped unit may come back healthy | The maker carries diagnosis cost before any remedy is owed | The no-fault-found clause: who pays freight and handling when nothing was wrong |
| Natural fit | Single-point and uptime-bound sites, where every down day is visible | Sites with redundancy, or portables swappable from a shelf | The model’s scope: whole units, named parts, or both |
Both models run on the same rails: the claim evidence pack, and a return route for failed hardware. The published spare parts and RMA process walks that pipeline; the model decides what travels it, and in which order.
What Makes Either Model Work
- Stock is the swap model’s real promise. Advance replacement restores a site only as fast as swap stock exists for that exact model and configuration. Ask where it sits and what replenishes it — a model name without stock behind it is a slogan.
- Diagnosis quality is the repair model’s real speed. Fault codes, session records and a complete evidence pack shorten it more than any promise does.
- Your own shelf changes the arithmetic. An operator holding handled parts, or a complete spare on a single-point site, may never feel the wait.
- Downtime cost is the buyer’s figure. Price the down day from your own records, and let that number choose between the models.
EVDANCE’s Position, Stated Plainly
EVDANCE states a 3-year standard warranty. Its published facts do not state which remedy model sits behind that term — neither model is promised in them, and no response time is published. Where the model matters, it is a written-confirmation item: ask before signing which model applies to the exact unit — the EV-AC03201T dual-connector station (two Type 2 connectors, up to 43 kW shared, OCPP 1.6J, RFID, IP54) or the EV-RHDC30K-L compact DC charger (22 kW DC, OCPP 1.6J, IP54), where one failed connector is the whole site down. The answer belongs in the supply terms, obtained via the reseller and distributor program or contact us.
Frequently Asked Questions
Which model is better for a charging site?
The one matched to your downtime cost. A single-point public site buys swap speed because every down day costs revenue and trust; a multi-port site with spares may never feel repair-first’s wait. Decide from your own downtime figure; get the model written into the terms.
Does EVDANCE offer advance replacement?
It is not stated in EVDANCE’s published facts. The stated position is a 3-year standard warranty; the remedy model behind it — swap, repair-first, or a mix by part — is confirmed in writing for the exact order before signing.
What happens if the returned unit shows no fault?
The no-fault-found clause decides who pays the freight and handling for a healthy return. It separates the two models in practice — read it before relying on a swap arrangement.
