Laiyang runs on two tracks. The city core looks like any Yantai district — compounds, e-bike ports, a few AC chargers. The townships are different: small, dispersed, grid conditions all over the place, and usage intensity often higher than in the city because e-bikes carry more of daily life. Township projects fail when they are priced like city projects; they work when packaged.
Township projects that stay alive
Township demand is real and underserved — e-bikes work harder there, and dangling cables are more common. Our township recipe: low-temperature-rated components, IP54+ protection, anti-corrosion enclosures; billing that takes scan and card because older users still carry cards; and standardised packages that keep engineering costs sane on small sites. Where sites scatter, maintenance is remote-first — the platform diagnoses, restarts or reconfigures from a distance, and only real hardware faults get a truck roll.
The urban track
City compounds follow the usual arithmetic: one port per 30–50 active e-bikes, so a 500-household compound typically takes one or two 10-port stations, with a 1.3× margin if usage concentrates into 18:00–22:00. 7kW AC chargers add 300–400 km of range overnight on a parking-space circuit — gentle on the distribution room and enough for daily commuting.
Sequencing the investment
Mixed projects should start with e-bike ports, because their cash flow is fast and steady: RMB 1–2 per session at about 1.5 sessions per port per day. 7kW AC chargers earn RMB 15–25 a session (at 0.5–0.8 RMB/kWh service fee) — fewer sessions, bigger tickets, and they lift the compound's profile more than they lift revenue. 60kW+ DC fast charging costs RMB 30,000–60,000 per unit plus RMB 20,000–50,000 to install and connect, and only makes sense with real passing traffic. Build the cash-flow layer first, add vehicle charging when the data asks for it.
Coverage at 100 km
Laiyang sits roughly 100 km out. Our area-based model — remote diagnosis first, periodic inspection rounds, 4-hour fault response on the 7×24 platform — is what keeps scattered township sites running without a resident engineer in each one.
How we deliver in Laiyang 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
- Do you take small township projects in Laiyang?
- Yes — standardised packages (10-port basic, 10-port with shelter, 20-port, or the full package with fire kit and CCTV) keep small sites affordable, and scan-and-card billing fits older users.
- Should we buy e-bike ports and EV chargers together?
- Usually not. Start with e-bike ports for fast, steady cash flow; add 7kW AC chargers when vehicle ownership in the compound justifies it; DC fast charging only where real passing traffic exists.
- How do you maintain scattered township sites?
- Remote-first: the platform diagnoses and often fixes issues from a distance, periodic inspection rounds cover the rest, and true hardware faults get a dispatched crew with 4-hour response.
