Fushan is unusual in Yantai: the old town runs on stock-housing retrofit while the industrial parks and newer zones run on greenfield fit-out. Judging a Fushan site with the wrong playbook is expensive — retrofit sites live or die on grid headroom and siting, park sites on the AC/DC mix and billing design. We run both disciplines and phase construction by what the transformer can actually carry.
Two markets, two playbooks
- Old-town stock compounds — the binding constraints are grid headroom and parking geometry. Load measurement first; upgrade only if the data demands it. Charging locations usually come from idle corners and disused bicycle shelters.
- Parks and new zones — better capacity, so the questions are mix and billing: how many AC, how many DC, how employees charge, what visitors pay.
Reusing idle shelters instead of building new
Many Fushan compounds have abandoned or half-abandoned bicycle shelters, store rooms and odd corners between blocks. Converting them costs roughly 40–60% of a new shelter build — the shell, roof and hardstanding already exist. Before converting we check three things: structural capacity (especially snow load), a usable power access point, and whether the location blocks evacuation. If any of the three fails, we recommend a new location rather than forcing the old one.
Park charging: mix and billing
Our default park mix is 70–80% 7kW AC chargers for employees parked through the shift and 20–30% DC fast charging for visitors and business vehicles; logistics vans and shuttle buses get a separately planned high-power zone. Billing runs on three account classes — employees (monthly package or discounted rate), visitors (scan per kWh) and fleet vehicles (independently metered) — so the park's internal cost accounting stays clean.
Construction, protection grades and platform
Standard jobs run 7–15 days in phases to keep parking usable; park work is scheduled around production, including holidays or nights where needed. Fushan sits in the main urban area, so our O&M crews reach sites within 24 hours, with 4-hour fault response from the 7×24 platform. Equipment is specified by location: IP54+ outdoors (IP55+ near the coast or in garages), 304 stainless or hot-dip galvanised with fluorocarbon coating, shelter eaves at 2.2 m or higher with a roof slope of at least 5%, ZR cable and fire-stopped penetrations underground, tray earthing at 4 ohms. After handover the platform does the daily work — remote metering and restart, per-device revenue, automatic work orders, monthly reconciliation exports. Without that layer, chargers quietly become furniture.
How we deliver in Fushan District
- 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
- Can you convert our old bicycle shelter instead of building a new one?
- Often yes, at roughly 40-60% of new-build cost. We check three things first: structural capacity including snow load, a usable power access point, and clear evacuation. If any fails we say so and quote a new location instead.
- How should an industrial park split AC and DC chargers?
- Typically 70-80% 7kW AC for employees parked all shift and 20-30% DC for visitors and business vehicles, with logistics or shuttle fleets in a separately planned high-power zone. Billing is split into employee, visitor and fleet account classes.
- How long does a Fushan installation take?
- Standard community projects run 7-15 days, phased so parking stays usable. Park work is scheduled around production shifts, including nights or holidays where necessary.
