E-bike charging stations (two- and three-wheelers)
The mainstream product for community, campus and factory shelters. QR-code or card start, pay per port, full-charge auto-stop, overload / short-circuit / leakage protection — built for long unattended operation.
| Model | Typical use | Highlights |
|---|---|---|
| 10-port standard | Community shelters | Independent output per port (about 500–800W max), hourly or per-kWh billing, flame-retardant enclosure, IP54 |
| 20-port high density | Large shelters, factory areas | More vehicles per square metre, zoned staged power-up to soften load impact, multi-tariff schedules |
| Networked smart | Remotely operated sites | 4G/Ethernet to the platform, remote restart and firmware upgrade, automatic fault reporting, online orders and work orders |
Common parameters: billing by time, energy or monthly package (platform-configured); full-charge auto-stop, overload, short-circuit and leakage protection, temperature monitoring (model dependent); wall or pedestal mount with dedicated distribution box and circuit; platform integration with property revenue sharing and O&M work orders.
AC chargers for cars (slow charging)
The workhorse for private bays, workplace lots and hotel overnight parking: cheap to build, gentle on the grid, and a full night of off-peak charging.
- 7kW wallbox — single-phase 220V for private and underground bays; overnight charge covers most commuters; small size, fast installation; card / QR / plug-and-charge options.
- 7kW / 14kW pedestal — higher ingress protection for outdoor and commercial lots; dual-gun variants serve two bays from one unit; platform billing and access control.
- Smart ordered charging — allocates power dynamically within transformer capacity, so 2–3 times as many chargers run without a grid upgrade; off-peak priority and queueing built in; communication and power interfaces reserved for expansion.
Installation requirements: dedicated circuit and breaker, reliable earthing, cable cross-section sized by power and distance; leakage, over/under-voltage and earth-detection protection, emergency stop (model dependent).
DC fast chargers (bus, logistics, public stations)
- 60kW integrated — entry fast charging for small sites and fleets; single or dual gun; modular power blocks swap out quickly; platform settlement.
- 120kW dual-gun — the public-station workhorse; dynamic power split between guns raises bay turnover; wide output voltage covers mainstream vehicles; remote O&M and early warning.
- 240kW and above — bus and heavy-truck fleets; high output with optional liquid-cooled cables; scheduled power dispatch trims peak tariffs.
DC fast charging involves transformer capacity and possible grid reinforcement: the investment and approval cycle is an order of magnitude above slow charging. We recommend a load study and a utility consultation before choosing models and quantities.
Charging shelters (membrane / steel / PV)
A shelter is not decoration — it is the compliant way to separate charging areas from evacuation routes, and it doubles equipment life in Yantai's coastal climate. We design and build the whole package: foundation, structure, drainage, fire separation and lighting.
- Membrane (PVDF) — light, large span, fast build; fits mid-to-high-end communities and demonstration sites.
- Steel structure — high strength and long spans; polycarbonate or steel roof options to match budget.
- PV shelters — generate on the roof while charging below; pair with storage for a PV-storage-charging site (see our PV-storage-charging page).
Dongdian Huichong platform
User mini-program: scan to charge, WeChat/balance payment, auto-stop, orders and e-invoices, in-app fault reporting. Property dashboard: tariffs and packages, revenue sharing and reconciliation reports, alarm handling. O&M module: inspection plans with photo check-in, fault tickets, spare-part records. Multi-site operators see every station in one console, which is what keeps a scattered network manageable.
Specifications are typical ranges, not a quotation. Final parameters follow the site survey, the nameplate and the contract technical annex. Entrepreneurship involves risk; invest with caution.
