In 2025, the number of new energy vehicles in China exceeded 80 million. Annual demand for highway charging grew by more than 200%, while the number of fixed charging piles increased by only 50%, further aggravating the imbalance in the vehicle-to-charger ratio. During holidays, “one hour of charging after three hours of queuing” has become common at highway service areas, exposing the fundamental conflict between the “spatial rigidity” of fixed charging piles—which require land and grid connections—and the “spatiotemporal flexibility” of travel demand, characterized by holiday surges and dispersed demand in remote areas. As fixed charging piles face both “tidal” demand and constraints on land and grid capacity, EAX’s Energy Mobility Series and other representative mobile energy replenishment systems are evolving from “emergency alternatives” into “essential energy replenishment solutions.” Combining EAX’s product portfolio with its implementation experience, this article provides an in-depth analysis of how mobile charging vehicles, mobile charging and storage vehicles, and mobile power supply vehicles are reshaping highway energy replenishment and bringing the ultimate vision of “energy finding the vehicle” to life.

I. The “Holiday Curse” of Highway Charging: Why Are Fixed Charging Piles Never Enough?

1.1 The Truth behind the Vehicle-to-Charger Mismatch

As of 2026, the number of charging piles in China had exceeded 21 million. Behind this seemingly impressive figure, however, lies a serious structural imbalance. In Shandong Province, for example, more than 20,000 electric heavy-duty trucks are supported by only 443 charging stations, and dedicated charging piles for heavy-duty trucks account for less than one quarter. Similar problems exist in major logistics provinces such as Hubei and Henan, where vehicles and energy replenishment facilities are mismatched in both location and power capacity—large numbers of slow chargers remain idle, while high-power fast-charging and battery-swapping facilities at highway service areas and logistics hubs are extremely scarce.

1.2 Wave-Like Energy Replenishment Demand Overwhelms Fixed Facilities

Highway traffic during holidays displays a typical “tidal effect”: charging pile utilization at service areas is below 10% on ordinary days, but demand increases by more than tenfold during holiday peaks. Because the location, number, and power capacity of fixed charging piles cannot be adjusted, they cannot respond efficiently to such dramatic fluctuations. Operators may invest heavily in expansion, only to leave the facilities idle during ordinary periods; without expansion, the system becomes overwhelmed during holidays. This conflict was further intensified during the Dragon Boat Festival, National Day, and other holiday periods in 2026.

1.3 Hubei Practice: Mobile Charging and Storage Vehicles Become the Key to Breaking the Deadlock

In June 2026, the “Chutianshu Mobile Charging and Storage Vehicle” was officially deployed at highway service areas in Hubei. This marked the industry’s shift from the traditional approach of adding more charging piles and expanding capacity toward a flexible “mobile energy replenishment” solution. On ordinary days, a mobile charging and storage vehicle can charge with off-peak electricity in an industrial park and earn revenue from peak-valley electricity price differences. During holidays, it can be dispatched to a service area as temporary capacity expansion equipment, instantly adding 960kW of charging capacity and easily handling peak traffic. This practice provides a replicable model for upgrading highway energy replenishment systems nationwide.

II. Mobile Energy Replenishment: A Revolution from “Vehicles Finding Chargers” to “Energy Finding Vehicles”

2.1 Three Core Forms of Mobile Energy Replenishment

According to EAX’s “Energy Mobility Series” product portfolio, mobile energy replenishment systems can be divided into three main forms:

Table

2.2 Disruptive Business Logic: Peak-Valley Arbitrage + Emergency Dispatching

Mobile energy replenishment equipment is no longer an emergency asset that “only costs money without generating revenue.” Take EAX’s mobile charging and storage vehicle as an example:

· During ordinary periods: It is parked in an industrial park or battery-swapping station with low electricity prices and used as a fixed energy storage facility. It charges with off-peak electricity and earns revenue from peak-valley electricity price differences, thereby achieving “self-sustaining profitability.”

· During peak periods: It is dispatched to highway service areas as capacity expansion equipment, generating secondary returns through social benefits + service fees.

· Exceptional mobility: Built on a heavy-duty semi-trailer chassis with a gross towing mass of 35-40 tons, it can be flexibly dispatched to any location requiring energy replenishment.

2.3 Core Advantages: No Site Restrictions, No Power Restrictions, and Rapid Deployment

Compared with traditional fixed energy replenishment facilities, EAX’s mobile energy replenishment system offers three breakthrough advantages:

· No site restrictions: No site selection, civil construction, or grid capacity expansion is required. Even ground hardening is unnecessary because the tractor chassis provides built-in mobility, enabling charging wherever the vehicle goes.

· No power restrictions: The mobile charging and storage vehicle carries 1.935MWh of energy storage, while the mobile power supply vehicle can replace its battery at any heavy-duty truck battery-swapping station, achieving “unlimited range.”

· Rapid deployment: System integration and commissioning are completed before delivery. The equipment can begin operating within as little as one hour after arriving on site, making it truly “ready to use upon arrival.”

III. EAX Energy Mobility Series: The Ultimate “Arsenal” for Mobile Energy Replenishment

Leveraging its full-stack, independently developed capabilities in mobile energy, EAX has established a complete mobile energy replenishment product portfolio covering “storage, charging, battery swapping, and power delivery.”

IV. In-Depth Application Scenarios: The Versatile Value of Mobile Energy Replenishment

The value of EAX’s mobile energy replenishment solution extends far beyond highway service areas. The following six scenarios represent its primary applications:

Scenario 1: Peak Capacity Expansion at Highway Service Areas (A Core Supplement to Fixed Charging)

· Pain point: Charging queues at service areas are lengthy during holidays, while the power and number of fixed chargers cannot meet short-term surges in demand.

· Solution: EAX mobile charging and storage vehicles are routinely stationed at service areas. They store off-peak electricity during ordinary periods and discharge energy during holiday peaks, effectively “temporarily adding a six-gun charging station” to the service area.

· Value: No facility expansion, no grid capacity increase, and no civil construction, transforming the “rigidity” of fixed charging into the “flexibility” of mobile energy replenishment.

Scenario 2: Mines and Construction Sites without Grid Coverage

· Pain point: Remote mining areas and construction sites lack grid coverage, while diesel generators produce high emissions, excessive noise, and high operating costs.

· Solution: A combination of mobile power supply vehicles + mobile charging and storage vehicles provides mobile energy replenishment for electric mining trucks, excavators, and construction machinery.

· Implementation case: EAX applications in oil and gas field projects have delivered more than 2,300MWh of off-grid electricity while replacing diesel generators and significantly reducing fuel costs and carbon emissions.

Scenario 3: Charging Station Construction and Upgrade Periods

· Pain point: New charging stations have long construction cycles, leaving operators with “chargers without power” or “chargers without demand” during construction and capacity expansion periods.

· Solution: Before the fixed station is completed, mobile energy replenishment vehicles provide temporary charging services and help operators capture market opportunities. They can subsequently serve as fixed energy storage/capacity expansion equipment at the station, continuing to generate value.

Scenario 4: Large Events and Emergency Power Supply

· Pain point: Sports events, music festivals, exhibitions, and other large events create substantial temporary electricity demand while imposing strict noise and environmental requirements.

· Solution: Mobile power supply vehicles providing stable 400V AC output + mobile charging and storage vehicles providing high-power charging services.

· 

· Value: Zero emissions, low noise, and rapid deployment. The equipment can be removed immediately after the event, preventing fixed facilities from becoming idle.

Scenario 5: Peak-Valley Arbitrage in Industrial Parks/Logistics Hubs

· Pain point: Electricity prices are high during the day and low at night, while many parks lack the space or approvals required to build fixed energy storage facilities.

· Solution: A mobile charging and storage vehicle is normally stationed in the park as a “mobile energy station,” charging with off-peak electricity at night and discharging or charging park vehicles during daytime peaks.

· Value: Generates direct revenue from peak-valley electricity price differences while providing the park with flexible, mobile energy support.

Scenario 6: Disaster Relief and Emergency Support

· Pain point: Earthquakes, floods, and extreme weather can interrupt the fixed power grid, creating urgent temporary power requirements for rescue equipment.

· Solution: EAX mobile charging vehicles/power supply vehicles can be dispatched immediately to disaster areas to provide mobile energy for rescue command equipment, lighting, communications, and electric rescue vehicles.

· Value: Clean, reliable, and mobile, unaffected by grid failures and serving as the “energy core” of rescue operations.

V. Market Prospects and Equipment Selection Recommendations

5.1 Mobile Energy Replenishment Enters a Period of Rapid Growth

Driven by the dual-carbon goals and the integration of wind, solar, and energy storage, mobile energy replenishment has evolved from an “emergency alternative” into an “essential industry solution.” Data shows that by 2026, EAX had delivered more than 900 units and systems, with products deployed in more than 50 countries and regions and operating at scale across highways, mines, ports, emergency applications, and other fields.

5.2 How Should the Right Mobile Energy Replenishment Equipment Be Selected?

Table

5.3 Key Equipment Selection Tips

· Do not focus solely on price; evaluate total lifecycle costs: EAX equipment adopts standardized and modular designs. Core components have passed more than 16,000 durability tests, while battery-swapping stations and energy replenishment equipment can provide a service life of up to 8-12 years. Their long-term amortized costs are significantly lower than those of inexpensive equipment requiring frequent repair and replacement.

· Do not overlook training and after-sales service: EAX provides a complete service chain covering equipment sales, production, installation and commissioning, and operational training. It has also established a 24/7 rapid-response after-sales maintenance system.

· Do not include civil construction or grid capacity expansion commitments: The essence of mobile energy replenishment is to “avoid the rigidity of land-use requirements.” Before selecting equipment, responsibility for civil construction and grid capacity expansion must therefore be clearly defined. EAX only provides equipment delivery and commissioning.
