Qixia is the exception in Yantai: inland, hilly, with winters down to about −14°C and communities scattered along mountain roads instead of gridded across a plain. Sites are smaller, decision chains shorter, and margins thinner — which is exactly why we run a package catalogue here instead of custom-engineering every ten-port station.
Terrain decides the playbook
- Urban compounds — modest in scale; a single project is usually one or two 10-port stations, decided quickly.
- Township and rural communities — scattered and small; standardised packages plus remote-first O&M keep them affordable to build and alive to maintain.
- The apple industry — Qixia grows the fruit; cold-chain warehouses and transport fleets are an emerging charging scenario we size separately from residential work.
Designing for −14°C winters
Qixia records Yantai's lowest temperatures: low-temperature-rated components, anti-freeze cabling (ordinary PVC stiffens and cracks), and foundations poured below the local frost depth so frost heave never lifts a cabinet out of level. After heavy snow or freezing rain, terminals and earthing get checked — the platform's remote diagnostics flag anomalies before anyone drives out.
Standardised packages keep small sites viable
Custom-designing a ten-port station costs more than the station. Our Qixia catalogue: a 10-port basic package (RCD box, signage, standard cabling), a 10-port sheltered package, a 20-port standard package, and the complete package — 10 ports plus shelter plus fire kit and CCTV. The survey confirms package type and cable length, the quote comes out the same day, and installation is days, not weeks. Same safety list inside every package: dedicated circuit, per-port 30 mA RCD, overload self-recovery, full-charge stop with 8-hour cap, extinguishers, monitoring.
How we deliver in Qixia City
- Free survey — site walk-through, photos, clamp-meter load recording where capacity is tight, then a written proposal with a fixed price.
- Grid application — we prepare drawings and paperwork and deal with the power supply company, so the property does not chase forms.
- Construction — in-house crews, cable trays and distribution boxes done to specification, typical duration 7–15 days.
- Platform onboarding — every device registered on Dongdian Huichong: scan-to-charge, billing, remote control, revenue dashboards and automatic fault work orders.
- Operation and maintenance — 7×24 monitoring, 4-hour fault response, on-site attendance within 24 hours, local spare parts, quarterly inspection.
Four safety configurations we do not cut
| Configuration | What it does | Why it matters |
|---|---|---|
| Independent RCD per port | 30 mA trip, under 0.1 s | One faulty port does not cut the whole station or other residents' charging |
| Overload cut-off with self-recovery | Breaks on abnormal current, restores automatically | Ageing batteries and poor chargers can pull 500 W+; unmanaged heat is a main fire cause |
| Full-charge auto-stop plus 8-hour cap | Stops on detected full charge, hard stop at 8 h | Prevents overcharge swelling and endless floating |
| Power-off memory | Restores billing state after an outage | Avoids disputes during the stormy season |
Three ways to cooperate
| Model | Cash flow for the property | Revenue share |
|---|---|---|
| We invest and operate | Zero cost; positive from month one | Property receives 30–40% of service-fee revenue |
| Joint investment | One-off contribution; payback typically 3–5 years | Property share up to 50–60% |
| Property buys, we maintain | Largest upfront spend | All revenue to the property; annual O&M fee |
Whichever model you choose, the property gets a platform account and sees every session, hour and yuan of revenue in real time. Settlement is calculated on the platform, so reconciliation is a report, not an argument.
Reference price ranges
| Scope | Reference range (RMB) |
|---|---|
| 10-port e-bike station incl. standard installation (cabling within 30 m, RCD box, signage) | 12,000–22,000 |
| 20-port e-bike station incl. standard installation | 18,000–32,000 |
| 7kW AC charger, device | 1,500–3,500 per unit |
| 7kW AC charger, installation | 1,000–2,500 per unit |
| 60 m² charging shelter with 10 ports, fire kit, lighting and CCTV | 35,000–55,000 |
These are public industry reference ranges, not a Dongshang quotation. Site conditions vary widely across Yantai; the binding figure is the fixed-price quotation issued after a free survey. We quote one price with no hidden additions.
Common questions
- What does the Qixia cold do to charging equipment?
- Two things: electronics and cabling need low-temperature ratings, and foundations must pass the local frost depth or frost heave tilts the cabinets. We specify for both and check terminals and earthing after severe weather.
- Our compound only needs ten ports. Is that worth doing?
- Yes — that is what the package catalogue is for: fixed scopes, same-day quotes, short installation. A 10-port basic or sheltered package carries the same safety list as a big project.
- Do you serve charging for apple storage and transport sites?
- Yes — cold-chain warehouses and transport fleets are a growing scenario. We size those zones separately from residential stations, around vehicle schedules rather than household counts.
