In the past, charging stations served as the logistical support for vehicle fleets; today, they have become the core operational lever for these fleets.
For operational fleets such as heavy-duty trucks, logistics convoys, and mining transport operations, building dedicated charging stations has evolved from an "optional" to a "mandatory" requirement. This solution not only addresses the critical need for energy replenishment but also enables businesses to: secure lower operating costs, maintain flexible service schedules, and upgrade their business models.
In short: When your fleet exceeds 15–50 vehicles, building your own charging stations is no longer a cost but a profit driver, with an investment payback period of just 1.5–3 years.
Smaller scale? Public stations offer greater flexibility. Larger scale? Building your own station saves you a substantial net profit.
The highest cost for public charging stations is not electricity, but service fees.
A service fee of 0.2–0.6 yuan is charged per kilowatt-hour of electricity.
A heavy-duty truck consumes 180,000 kWh of electricity annually → Each vehicle incurs an additional annual cost of ¥18,000 to ¥36,000.
50 vehicles → An additional annual expenditure of nearly 2 million yuan
Self-built website: Service fee = 0.
More importantly, you can charge your device during off-peak nighttime hours (0.3–0.5 yuan per kWh) and utilize the stored energy during daytime, reducing the overall cost per kWh by an additional 20%–30%.
The biggest issue with public charging stations isn't their high cost, but their unreliability:
Heavy trucks take 1–2 hours to charge, resulting in longer queues → disrupting transportation schedules
Detour energy replenishment → Increased idling time and driver workload
Self-built website:
The car can be charged right after returning; people keep parking without stopping.
Charging stations can be established in mining areas, ports, and major transportation hubs, allowing for efficient energy replenishment without detours.
Attracting major clients: A stable energy replenishment network provides the foundation for long-term transportation contracts.
Diversified revenue streams: driver canteens, lounges, and parking services → These revenues are already substantial at many power stations.
scheme | Who is it suitable for? | configure | Vehicle-to-Charging Station Ratio | merit | pay attention to |
Basic Dedicated Station | Limited budget, closed fleet, nighttime charging | Transformer + DC Single Pole | 4:1 | Low investment, quick return on capital | No peak-valley income |
Integrated solar power, storage, and charging station | Large area (≥10 mu), with a focus on long-term low electricity costs | Photovoltaic + Energy Storage + Group Charging and Control | 1.5:1 | Extremely low electricity costs, grid-friendly operation, and black-start capability① | The investment is slightly higher. |
Note ①: Black Start. Simply put: When the power grid fails and all other charging stations become unavailable, your station can still automatically resume operation to continue charging vehicles.
Professional recommendation: In the initial stage, it's not necessary to achieve perfection immediately. First, ensure the basic charging mode operates smoothly and data transmission is stable, then gradually increase the energy storage capacity in proportion—a more prudent approach.
Take a fleet of 50 heavy-duty trucks as an example:
Annual electricity consumption: 50 vehicles × 600 kWh/day × 300 days = 9 million kWh
Service fee savings: 9 million kWh × 0.3 yuan = 2.7 million yuan/year
Electricity cost savings (off-peak vs flat-rate electricity): 9 million kWh × 0.3 yuan price difference ≈ 2.7 million yuan/year
It saves over 5 million yuan in annual operating costs compared to public charging stations.
A station in Changsha, China: The 180-charging gun optical energy storage and charging station generates an average daily revenue of 30,000 yuan, while the annual venue rent contributes 560,000 yuan to the village collective income.
China Shanxi High-Speed Heavy Truck Station: Over 400 vehicles were served in a single day, with a maximum daily charging capacity of 86,000 kWh. The potential of the heavy truck charging corridor has been demonstrated.
1. Agreement mismatch
The charging station protocol must be fully compatible with the heavy-duty truck BMS; otherwise, vehicle speed will be significantly reduced.
✅ Just as an iPhone cannot be charged with a Huawei charger.
2. The Vehicle-to-Charging Station Ratio Trap
According to the 1:4 ratio, 100 vehicles are paired with 25 charging stations. If vehicles return in large numbers, queues will still form.
✅ Simulate the operational schedule before designing.
3. Power capacity is a hard threshold
Transformers and high-voltage power connections are among the most scarce resources.
✅ Prioritize securing power capacity before discussing equipment procurement; otherwise, the project will stall.
4. The equipment has not evolved
Technological iterations occur rapidly; equipment purchased today may become obsolete in the future.
✅ Prioritize devices that support photovoltaics and have reserved interfaces for easy upgrades to solar storage and charging systems.
Now, equipping fleets with charging stations is no longer a logistical expense but a key source of profit.
Self-built charging stations = Lower costs + Higher attendance + More stable business + Diversified revenue streams
If you have:
Stable Line
A fleet of more than 15 vehicles
An operational cycle of over 2 years
Building your own website is now a must.
When conditions permit, it is advisable to incorporate optical storage and charging interfaces from the outset—this is a critical decision for maintaining low-cost operations over the next 5–10 years.
