In recent years, with the continuous deepening and implementation of the "dual carbon" goals, coupled with the replacement of electric heavy-duty trucks and the support of policies for green trunk line transportation, the popularization speed of the new energy heavy-duty truck market has once again exceeded the expectations of the entire industry. According to the joint statistics of the First Commercial Vehicle Network and terminal traffic insurance, from January to June 2025, the cumulative sales of domestic new energy heavy-duty trucks reached 79,200 units, a year-on-year increase of 186%. In June alone, the market penetration rate exceeded 26%, hitting a new historical high, covering all commercial scenarios such as short-distance port transportation, urban municipal sanitation, long-haul trunk line logistics, mining area engineering operations, and steel plant sand and gravel transportation.
The construction of supporting heavy-duty truck-specific charging stations has also entered a period of high-speed expansion. In the first half of 2025, more than 1,800 heavy-duty truck-specific charging stations were added nationwide. Operators and enterprises from logistics parks, highway service areas, industrial parks, ports and mining areas are accelerating their entry and layout, and the investment enthusiasm in the industry continues to rise.
After analyzing hundreds of station practitioners across the country, it was found that nearly 60% of the cases of construction losses and unsatisfactory operation are rooted in the charging pile selection link: some people贪图 the low price of equipment and purchase integrated charging piles in batches. Later, the capacity of the park transformer is saturated and limited, and the station can only reduce the number of charging guns by 3-4 for use, directly reducing the annual charging revenue by hundreds of thousands of yuan; other operators blindly launch megawatt-level group charging equipment after轻信 the high-power gimmick of manufacturers. In fact, the station only has 5-8 fixed vehicles for cyclic charging, and the equipment is idle under low load for a long time, directly extending the payback period of the station by more than 2 years.
As the industry's senior operation service providers generally agree: once the early selection of heavy-duty truck charging stations is wrong, it has become the industry norm to invest an additional 100,000 to 200,000 yuan in sunk costs before generating stable cash flow.
PART 01 Clarification: There are only two types of mainstream heavy-duty truck charging stations at present Many practitioners are confused by various terms such as "liquid-cooled ultra-fast charging piles", "flexible distribution piles" and "intelligent group charging piles" promoted by manufacturers when they first come into contact with heavy-duty truck charging piles. In fact, divided by technical architecture, all commercial heavy-duty truck charging stations on the market are essentially divided into two categories: the first type is integrated charging piles, and the second type is megawatt group charging systems.
The core difference between the two lies in the layout of power modules: the power modules of integrated charging piles are directly integrated inside the pile body, and each pile operates independently; while megawatt group charging concentrates all power modules in a unified power stack, and only charging terminals without modules are installed at the parking space end, and all terminals share the capacity of the power stack, and power is allocated through system scheduling.
Next, we will explain the differences between the two types of products from three dimensions: core parameters, advantages and disadvantages, and applicable scenarios.
PART 02 Comparison of core parameters: Where are the differences in price and power? The core premise of selection is to first understand the differences in basic parameters between the two types of products. We take the industry-universal dual-gun simultaneous charging and single-gun pricing as the unified measurement dimension, and compare the two core indicators of price and power:
(一) Price differences In the current mainstream industry procurement prices, the single-gun price range of integrated charging piles is 18,000 yuan - 25,000 yuan, and the single-gun (terminal) price range of megawatt group charging is 25,000 yuan - 30,000 yuan. If a medium-sized heavy-duty truck charging station with 10 charging guns is built, the total procurement cost of integrated charging piles is about 180,000 - 250,000 yuan, and the total procurement cost of megawatt group charging is about 250,000 - 300,000 yuan. The maximum price difference at the procurement end alone can reach 120,000 yuan, which just corresponds to the common pain point in the industry of "spending 100,000 yuan more for choosing the wrong pile". It should be noted that the above quotes only refer to the procurement cost of the pile body itself, excluding costs such as transformer capacity expansion and site construction. The differences in subsequent supporting costs between the two types of products will be specifically explained in the advantages and disadvantages section.
(二) Power differences Integrated charging piles have a wide range of product models, covering the full power range of 320kW, 400kW, 480kW, 600kW and even 720kW. At present, the most widely used in the market is the 400kW dual-gun integrated charging pile, with an average single-gun output power of up to 200kW, which does not need to share capacity with other piles. The rated output power of a single gun for megawatt group charging is generally 160kW-240kW, but since all terminals share the total capacity of the power stack, the peak power of a single gun can be flexibly adjusted upward: if it is a 1.6MW power stack, the peak power of a liquid-cooled dual-gun output terminal can reach up to 1600kW when dual guns are charged simultaneously; if it is a 2.5MW power stack, the peak power of a liquid-cooled dual-gun output terminal can reach up to 2400kW when dual guns are charged simultaneously. As long as the vehicle battery supports it, rapid energy replenishment can be achieved. In short, the advantage of integrated charging piles is stable average single-gun power, while the advantage of megawatt group charging is higher peak power limit of a single gun. The differences in power characteristics between the two directly determine their applicable scenarios.
PART 03 Analysis of advantages and disadvantages: What needs do the two types of products respectively suit? Many stations only look at the surface indicators of price and power when selecting products, and often ignore the implicit differences between the two types of products in actual operation. Next, we will analyze the advantages and disadvantages of the two from the perspective of the entire operation cycle:
(一) Advantages and disadvantages of integrated charging piles
Advantages
First, the procurement cost is low. Taking the most commonly used 400kW dual-gun integrated charging pile as an example, the current mainstream industry procurement price is 38,000 yuan - 50,000 yuan per unit. The early procurement cost of a station of the same scale is 15%-20% lower than that of megawatt group charging, which is suitable for small and medium-sized players with limited budgets to enter the market.
Second, the single-gun power is stable, and there is no need to share capacity with other terminals. As long as the vehicle supports it, the single gun can stably maintain an output power of 200kW, and there will be no power drop when multiple vehicles are charging at the same time. It is more adaptable to scenarios with high requirements for charging efficiency.
Disadvantages
First, the power waste rate is high. At present, more than 70% of operational new energy heavy-duty trucks on the market have a maximum charging power of only 280kW-360kW, which is far from reaching the total capacity limit of 400kW-480kW integrated charging piles. The remaining 40kW-120kW power cannot be allocated to other vehicles, and the long-term idle power waste rate can reach more than 20%, directly reducing the overall revenue of the station.
Second, the floor area is large. Since the power modules are directly integrated inside the pile body, a single 400kW integrated charging pile covers an area of about 1.2-1.5 square meters. Many stations with limited site area and narrow parking spaces cannot be laid out at all, or the vehicles are inconvenient to park after the piles are installed, which instead reduces the turnover efficiency of parking spaces.
Third, the operation noise is loud. Each integrated charging pile has its own independent heat dissipation module, and the general noise during operation is above 75 decibels, which is equivalent to the noise level of a busy street. The experience of drivers resting beside the parking space is extremely poor, and it is easy to lose fixed customers.
(二) Advantages and disadvantages of megawatt group charging
Advantages
First, the peak power limit is high. As long as the vehicle battery supports it, the single-gun peak power of megawatt group charging can fully utilize the capacity of the entire power stack, and the energy replenishment speed is 3-5 times faster than that of traditional integrated charging piles. It fully adapts to the energy replenishment needs of future high-power new energy heavy-duty trucks, and will not become obsolete shortly after the station is built.
Second, the floor area is small. The charging terminal at the parking space end does not contain power modules, and the floor area of a single terminal is only about 0.3 square meters. Stations with limited site area can also layout more charging gun positions.
Third, the iteration cost is low and the anti-obsoleteness ability is strong. If it is necessary to upgrade to liquid-cooled ultra-fast charging and adapt to higher-power vehicles in the future, only the charging terminals at the parking space end need to be replaced, and the power stack and transformer can be retained. The upgrade cost is only about 20% of that of the integrated solution, and there is no need to replace all pile bodies.
Fourth, flexible power allocation. All charging terminals share the total capacity of the power stack, and the system can dynamically allocate power according to the charging demand of each vehicle. For example, a 200kW sanitation truck is allocated 200kW, and a 600kW trunk line heavy-duty truck is allocated 600kW. There is basically no power waste, and the overall capacity utilization rate of the station is more than 30% higher than that of the integrated solution.
Fifth, the operation noise is low. All power modules and heat dissipation systems are concentrated in a unified power stack, which can be placed in a dedicated station room. The charging terminal at the parking space end has almost no noise, and the noise in the charging area can be controlled within 60 decibels, which is equivalent to the volume of normal conversation. Drivers have a better rest experience, and it is easier to accumulate fixed customers.
Disadvantages
First, the early procurement cost is high. The single-gun procurement price is 5,000 yuan - 8,000 yuan higher than that of integrated charging piles. The total procurement cost of a station with 10 charging guns is 50,000 - 80,000 yuan higher, plus the installation cost of the power stack, the maximum difference in early investment can reach 120,000 yuan, which puts great pressure on small operators with tight budgets.
Second, the average power is low during full-load operation. If all gun positions in the station are charging at full power at the same time, the average single-gun output power is only 130kW-180kW, which is about 20% lower than the 200kW of integrated charging piles. For trunk line mid-way energy replenishment scenarios with extremely high requirements for charging efficiency, some vehicles may have insufficient energy replenishment speed and lose customers.
PART 04 Selection guide: Choose integrated charging piles for 5 types of scenarios, Choose megawatt group charging for 6 types of scenarios There is no absolutely good product, only suitable products. You can match your selection plan directly according to the following scenarios, without blindly pursuing high-end or low-priced products:
(一) 5 types of scenarios where integrated charging piles are preferred
Small and medium-sized operators with limited budgets: If the total budget for initial station construction is within 500,000 yuan, priority should be given to integrated charging piles. The early investment is small, installation and operation are simple, and the payback period is shorter, which is suitable for small players entering the market for the first time to test the waters.
Small stations with sufficient site conditions: If the length space of a single parking space and the parking access space are sufficient, and the number of charging guns planned for the station is less than 6, there is no need to reserve a separate installation space for the power stack. Integrated charging piles have higher cost performance, and there is no need to share the cost of the megawatt group charging power stack.
Enterprise-owned stations: If it is an enterprise-owned logistics fleet or an exclusive charging station inside a port, all vehicles are owned by the enterprise, and the charging time is fixed, there is no need for external operation. The stable power of integrated charging piles can fully meet the demand, and there is no need to pay extra for flexible distribution functions.
Stations with fixed vehicle requirements: If the charging power of vehicles served by the station is uniformly in the range of 300kW-480kW, such as trunk line heavy-duty truck fleets with fixed routes and unified vehicle parameters, choosing 400kW-480kW integrated charging piles just matches the demand, and there will be no power waste.
Stations with small demand for charging guns: If the number of charging guns planned for the station is less than 6, the cost of the megawatt group charging power stack cannot be shared, and the total investment is actually higher than that of integrated charging piles. You can directly choose integrated charging piles.
(二) 6 types of scenarios where megawatt group charging is preferred
Public operation stations with sufficient budgets: If it is a public logistics park or trunk line mid-way energy replenishment station open to social vehicles, and plans to operate for a long time, although the early investment is 50,000 - 100,000 yuan more, the long-term capacity utilization rate is higher, the iteration cost is lower, and the price difference can be covered within 3 years, with greater subsequent profit space.
Stations serving complex vehicle types: If the station serves a variety of vehicle types, including 200kW municipal sanitation trucks, 400kW logistics heavy-duty trucks, and engineering vehicles above 600kW, the flexible distribution function of megawatt group charging can adapt to all vehicle types, avoiding the situation where low-power vehicles waste power and high-power vehicles cannot be fully charged.
Stations with insufficient power capacity: If the local power grid can only approve a capacity of 1500kVA or less, using megawatt group charging can layout about 30% more charging gun positions. The revenue brought by the additional gun positions can quickly cover the early procurement price difference, which is suitable for areas with tight power grid capacity.
Stations mainly serving low-power vehicles: If the station mainly serves municipal sanitation and urban distribution heavy-duty trucks, and the maximum charging power of the vehicles is generally within 200kW, megawatt group charging can layout more charging gun positions. A 1.6MW power stack can install 12 charging guns, 4 more than the integrated solution with the same capacity, resulting in higher parking space turnover efficiency.
Stations considering long-term iteration: If the station plans to operate for more than 5 years after construction and needs to upgrade to liquid-cooled ultra-fast charging to adapt to high-power heavy-duty trucks in the future, the upgrade cost of megawatt group charging is only tens of thousands of yuan, while the integrated solution requires replacing all pile bodies, with losses reaching hundreds of thousands of yuan. In the long run, megawatt group charging has higher cost performance.
Stations with low requirements for charging efficiency: If it is a municipal station for overnight parking charging or a supporting charging station for drivers to stay and rest, and the vehicle parking time is more than 3 hours, there is no need for 1-hour rapid energy replenishment. Megawatt group charging can match more charging gun positions, the single-gun operation cost is lower, and the overall revenue is higher.
PART 05 Three final reminders for practitioners to avoid pitfalls The investment payback period of heavy-duty truck charging stations is generally 2.5-3 years. The losses caused by wrong selection often take 1-2 years of operation to recover. Finally, here are three general suggestions to avoid pitfalls:
First, don't just look at the single-gun procurement price, but calculate the full-life cycle cost. Many people only see that megawatt group charging is thousands of yuan more expensive per gun, but ignore the capacity expansion cost it saves, higher utilization rate, and lower upgrade cost. Calculated over the full life cycle, it is actually cheaper than integrated charging piles.
Second, don't blindly pursue high power. Many manufacturers will promote "buy the highest power pile in one step", but if all the vehicles served by your station are 200kW sanitation trucks, buying a 720kW integrated machine or a 2.5MW power stack is a complete waste of funds. The suitable one has the highest cost performance.
Third, don't ignore the operation and maintenance cost. Each integrated charging pile has an independent power module. The annual operation and maintenance cost of a station with 10 charging guns is about 20,000 yuan higher than that of megawatt group charging. This is not a small expense in long-term operation, and this part of the cost should be included in the selection.
