With the rapid increase in the penetration rate of new energy vehicles, the imbalance between supply and demand in urban charging infrastructure has become increasingly prominent. Traditional fixed charging piles are constrained by land resources, grid expansion costs, and construction cycles, making it difficult to cope with regional tidal charging demand, the challenges of upgrading older residential communities, and weak support for emergency scenarios. Against this backdrop, 2MWh~4MWh-class mobile charging and energy storage vehicles have emerged. With the characteristics of “mobility, large capacity, and high power,” they have become an innovative solution to urban energy replenishment challenges, injecting new momentum into smart city development.

What Is a Mobile Charging and Energy Storage Vehicle? Unpacking This “Energy Black Technology”

It uses a transport vehicle equipped with a 2MWh~4MWh-class high-capacity battery system, which can store electricity in advance during off-peak tariff periods or at renewable energy power stations, and then provide efficient and rapid energy replenishment for new energy vehicles through onboard high-power charging modules. This design breaks the limitation of traditional charging facilities being tied to “fixed locations,” enabling flexible dispatching and on-demand deployment. It works like an energy-version bike-sharing system—“going wherever power is needed, leaving when the job is done, and responding on demand”—while also resembling a combination of a “giant power bank + delivery rider”: the energy storage system is responsible for “carrying the load,” while the dispatching system is responsible for “navigation,” working together to deliver high-power electricity precisely to where it is needed most.

Practical Application Scenarios: From Theory to Real-World Deployment
Mobile energy storage and charging vehicles are no longer just a concept. In older residential communities and city centers where fixed charging piles cannot be installed, they can flexibly enter these “charging blind spots” like an energy-sharing vehicle, charging up at low-cost nighttime electricity rates and responding on demand during the day. During large-scale events, holiday peaks, or sudden disaster scenarios, they can transform into a “delivery-rider-style power bank,” with dispatching systems assigning tasks precisely and enabling rapid deployment for vehicle charging or even emergency power supply. Going a step further, they can also interact with the urban power grid: quietly storing energy during low-tariff periods in the early morning and discharging to electric vehicles during daytime peak demand, helping the grid achieve “peak shaving and valley filling.” They can also connect directly to photovoltaic or wind power plants, storing intermittent green electricity and converting it into stable charging services, allowing new energy vehicles to truly run on “sunshine and wind.” 

The Mobile Energy Storage and Charging Vehicle Market: Rapid Competition and a Hundred-Billion-Yuan Blue Ocean Ahead

From a market data perspective, mobile energy storage and charging vehicles are rapidly moving from a niche energy storage segment toward large-scale industrialization. According to QYResearch, the global smart mobile energy storage charging vehicle market was valued at approximately USD 726 million in 2025 and is expected to grow at a compound annual growth rate of 8.2% from 2026 to 2032, reaching USD 1.217 billion. As the world’s largest new energy application market, China is expected to account for more than 25% of the global market by 2032, becoming a core growth engine. In terms of production, global output reached 35,398 units in 2025, with an average selling price of approximately USD 20,500 per unit, annual global production capacity of around 50,000 units, and a gross margin of approximately 30.7%. In the domestic market, China’s mobile energy storage vehicle market has already exceeded RMB 30 billion and is expected to maintain annual growth of more than 15% over the next five years, potentially surpassing RMB 60 billion by 2027.

Against the backdrop of accelerating industry development, companies represented by Nengyixing, a provider of full-scenario energy replenishment solutions, have already begun in-depth deployment in this market. The “Nengyu” series mobile energy replenishment system launched by Nengyixing serves as an important part of its core product portfolio. It can operate collaboratively with the Nengqing series commercial vehicle battery swap stations, Nengjie series passenger vehicle battery swap stations, Nengshan series chargers, and the independently developed “Nengxin” series battery packs, forming a complete energy replenishment ecosystem covering passenger vehicles, commercial vehicles, and specialized application scenarios.At the same time, the company has also built a cloud-based intelligent operation and maintenance platform that integrates AI predictive maintenance and digital twin technologies to enable real-time equipment status monitoring and fault warnings, improving operation and maintenance efficiency by 40% and reducing fault handling time by 50%.

From “struggling to find a charger” to “power coming to you,” and from “waiting in line” to “charge immediately upon arrival,” 2-4MWh mobile energy storage and charging vehicles are redefining urban energy replenishment through flexibility and efficiency. Looking ahead, as policy support continues to expand, AI dispatching algorithms become increasingly mature, and V2G bidirectional interaction is fully implemented, mobile energy storage and charging vehicles are expected to evolve from an “emergency supplement” into a “backbone node” of urban energy networks.
