Where community projects really get stuck
A charging station looks like a post and a cable. In practice more than nine in ten stalled projects fail on three things: where the power comes from, who approves, and who maintains.
Capacity comes first. Most Yantai communities built between 2005 and 2015 never carried a charging load in their electrical design. A 500-household community at a 10% simultaneous charging rate may need 300–500kW extra — which means a new transformer or load management. At survey we record three-phase load curves with clamp meters over seven full days before recommending reinforcement or peak-shifting — never just quoting hardware.
Approvals come second. Common-area construction touches the owners' committee, the property, the neighbourhood committee and the utility; one missing signature can stop the job. We prepare the package: construction plan, stamped electrical drawings, fire-safety notes, resident notices with posting photos, and the utility application.
Maintenance comes third. Installation is the beginning, not the end: charge faults, payment disputes, knocked devices, rain-tripped RCDs. Without a named O&M party, every complaint lands on the property's front desk.
Our five steps
- Free survey — measured capacity, routing, bay layout; a data-backed report.
- Design and quotation — models, counts, cabling method, whether reinforcement is needed; one fixed price, no add-ons.
- Application and notice — utility filing, committee liaison, public announcements from our templates.
- Construction — 7–15 days standard: civil works, cabling, devices, fire equipment, signage.
- Operation and O&M — Dongdian Huichong platform, 7×24 monitoring, 4-hour response, 24-hour attendance.
Survey to power-on usually takes 20–30 days; reinforcement adds 2–4 weeks on the utility's schedule.
Choosing equipment — not by price alone
E-bike ports price by count: market prices for 10-port units span RMB 1,500–4,000, and the spread hides in three items — whether each port has an independent RCD, whether overload protection self-recovers, and whether billing survives an outage. We standardise on all three plus full-charge auto-stop: those are the items that separate a safe station from an incident report.
Car chargers split into 7kW AC (underground and private bays; 300–400km of range overnight; gentle on the grid) and 60–120kW DC (surface public bays; needs dedicated circuits and real capacity). When comparing products, check: CCC certification (DC units also GB/T 18487 and GB/T 27930), ingress protection IP54 outdoor / IP55 in damp garages, platform capability (remote metering, remote restart, per-device revenue, exportable statements), and who actually shows up when it breaks — our crews are in Yantai, not in a parcel box.
Cost and payback, worked example
A 300-household community with a 20-port e-bike station: one-off equipment and construction about RMB 30,000–50,000. At 1.5 uses per port per day at RMB 1, monthly revenue runs about RMB 900; after electricity and management, payback typically lands in 18–30 months. 7kW AC chargers earn RMB 15–25 per session with service-fee splits commonly 3:7 or 4:6 (property : operator) — slower payback, but a visible upgrade to the community's amenities. Three cooperation models are available: self-procurement (we build and connect the platform only), our investment with revenue share, or joint investment — see property cooperation and the model comparison.
Compliance is not optional
The 2021 fire regulation for high-rise civil buildings bans e-bike parking or charging in lobbies, evacuation routes and stairwells, and Shandong includes charging provisions in inspections. A compliant build at minimum has: independent circuit supply, leakage and overload protection, automatic stop, fire equipment, physical separation from evacuation routes, and 24-hour monitoring or patrols. All of it goes into our construction plan and is checked item by item at acceptance — remediation after inspection is far more expensive than compliance up front.
Common questions
Do the owners have to vote? Common-area construction needs an owners' decision, organised by the committee or, in its absence, the neighbourhood committee or property — a path we run routinely. Can old communities without fixed bays do this? Yes: corner-plot public charging areas with 10–20 ports, shelters and fire equipment. Who do residents call when something fails? Not the property — our hotline +86 152-8878-3733, with 4-hour response and 24-hour attendance.
