Haiyang holds two markets in one coastline. The resort belt swings from quiet winters to summers several times busier; the city compounds behind it run on steady, year-round e-bike demand. Building one specification for both is the standard mistake — the resort needs staging and DC share, the compounds need ports and persistence.
Two markets, different rhythms
- The resort belt — car-led, seasonal, with visitors who top up fast between beach and hotel: the DC share rises and wayfinding matters.
- City compounds — e-bike stations as the backbone, a few 7kW AC chargers, demand that barely notices the calendar.
- Coastal townships — e-bike first, and the same salt-spray rules as anywhere on this coast.
Sizing for the season
The classic resort error is sizing to the annual average — queues in July, idle steel in January. We plan to the annual peak with 20–30% headroom, or better: run tray routes and grid capacity in one pass, then stage the devices — base load in year one, a top-up batch before the season. Capital stays productive instead of hibernating, and the hardware never sits long enough to age on the shelf.
Coastal corrosion protection
Haiyang is nearly ringed by sea. Enclosures in 304 stainless or hot-dip galvanised steel with fluorocarbon coating; shelters in aluminium or hot-dip steel; IP54 minimum outdoors. Ordinary powder-coated cold-rolled steel begins rusting within about two years on this coast — the saving on the quote turns into a replacement budget.
Pre-season inspection, stocked spares
Haiyang is about 120 km from central Yantai, so the O&M model is area-based: 7×24 platform monitoring, 4-hour fault response, critical spares in local stock. For resort projects we add one ritual — a full inspection and preventive-maintenance round before the season opens, because a dead charger in August costs more reputation than it costs to inspect in June.
How we deliver in Haiyang 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
- How do you handle the resort season swing in Haiyang?
- We plan to the annual peak with 20-30% headroom, or stage the hardware: trays and grid capacity in one pass, devices in batches, with a top-up installed before the season opens.
- Should the resort area get more DC fast charging?
- Yes — visitors dwell briefly and top up between destinations, so the DC share rises versus city compounds, paired with clear wayfinding. City compounds stay AC- and e-bike-led.
- What happens before the summer season?
- A full pre-season inspection and preventive-maintenance round on every resort site, with critical spares already in local stock — the goal is that no guest meets a dead charger in August.
