Mobile Energy Storage Vehicle Completes 5000 km Journey to Debut at ESIE 2025, Ushering in a New Era of Energy Solutions

Stepping out of the “comfort zone,” the mobile energy storage vehicle from Xinwangda traveled over 5,000 kilometers to make its debut at the ESIE 2025 International Energy Storage Summit and Exhibition in Beijing. Clean energy has now spread across the globe, and energy storage is entering various industries. However, there are still many untapped market opportunities on the user side.

During the ESIE 2025 event, Xinwangda’s mobile energy storage vehicle made the journey from Huizhou, Guangdong, igniting a new wave of energy storage applications. With the support of mobility, energy storage technology not only continues to address traditional peak-shaving and valley-filling needs but also enables energy transfer across locations to meet the unique power demands of remote areas.

As energy storage serves as a crucial balancing resource for the development of new energy and power systems, the global demand for construction is rising. Yet, some industries still rely on diesel generators for power, a method that is neither economical nor environmentally friendly. This can be effectively replaced by mobile energy storage technology.

As a comprehensive energy storage solution provider, Xinwangda is not only focused on macro-level applications but also on the challenges faced by power users in “marginal areas.” As a result, they unveiled the Xinjiyuan 2000 series, a 10-meter, 2MWh liquid-cooled integrated mobile energy storage vehicle, marking its global premiere.

The Xinjiyuan 2000 combines a liquid-cooled energy storage system, charging stations, and the vehicle itself, housing 40 small energy storage battery packs. Compared to conventional energy storage vehicles, it has been shortened by 3.4 meters, significantly enhancing its flexibility, while its energy storage capacity has increased to 2MWh, equivalent to the power consumption of an average household over two years. Importantly, it embodies a “comprehensive solution,” catering to a wide range of mobile energy needs.

For industries such as mining and oil fields, a key challenge in achieving a green and low-carbon transition is ensuring energy supply during outdoor operations. Since exploration and construction often occur in remote areas, diesel generators are commonly used to meet the power needs of large equipment and operations, resulting in high energy consumption and maintenance costs. The mobile energy storage vehicle can overcome these dispersed power demands by charging during off-peak hours and utilizing its mobility to discharge in required areas, saving costs by 15-20% compared to diesel generators, increasing power output by 1.3 times, and maintaining noise levels below 75 decibels, thereby significantly improving the working environment.

Moreover, the application scenarios for mobile energy storage vehicles are extensive for power grid companies. They can provide uninterrupted power during grid maintenance, support large events such as concerts, and serve as power sources during outdoor construction or emergency response situations. Additionally, with the rapid increase in the number of electric vehicles, challenges related to charging station construction and long charging times have become increasingly significant. Mobile energy storage vehicles offer a solution by allowing “charging stations to locate vehicles,” rather than the traditional “vehicles locating charging stations,” providing a more flexible method for emergency charging and alleviating the difficulties faced by electric vehicle owners.

According to Guo Junliu, Director of System Solutions at Xinwangda, the company’s approach to mobile energy storage is a proactive response to changing user needs, leveraging its technological advantages and market trends to promote the intelligent and multi-scenario development of the energy storage industry.

Facing challenges, road testing has validated the concept. Although mobile energy storage and power devices are not new to industry professionals, previous technologies were predominantly based on flywheel storage systems. Guo acknowledges the numerous challenges faced in the development of lithium battery mobile storage vehicles. One challenge is optimizing the layout of high-density energy batteries within a confined space while ensuring sufficient range. The integration of various systems also introduces complexities in thermal management, safety design, spatial constraints, and electromagnetic compatibility, necessitating a high degree of coordination and optimization.

Additionally, the mobile storage vehicle must maintain stability and safety amid bumps, vibrations, and potential collisions during transit, while reliably functioning in various environments and seasons to avoid safety issues like thermal runaway. The lack of a mature supply chain and supporting technologies in the industry means that many critical components require customized development, impacting research and development timelines.

The process of bringing such an innovative product to market involves multiple approvals, production qualifications, and road usage permits, requiring coordination among various departments, thus prolonging project timelines. Nonetheless, Xinwangda has successfully launched the first 2MWh large-capacity lithium iron phosphate battery mobile energy storage vehicle within a short timeframe, boasting five advantages: maximum capacity, integrated charging and discharging, shortest vehicle length, first liquid cooling system, and extreme safety. This product has also been featured on CCTV Finance.

From February 28 to April 6, this vehicle underwent extensive road testing over 5,000 kilometers, passing through over 20 cities, including Huizhou, Longyan, Nanchang, Xiaogan, Zhengzhou, and Shijiazhuang, before arriving at the ESIE 2025 exhibition in Beijing. During this rigorous journey across various terrains and temperatures, the Xinjiyuan 2000 showcased its practical design and superior performance.

As a crucial power supply device, the mobile energy storage vehicle’s primary focus is on ensuring stable and safe power delivery. Xinwangda leverages its vertically integrated capabilities across the entire value chain, from battery cells to system integration, to solve the customization challenges and design six safety barriers from internal components to the system as a whole.

Moreover, Xinwangda has introduced liquid cooling temperature control technology in the Xinjiyuan 2000, enhancing its volumetric energy density while ensuring the reliable operation of the mobile energy storage vehicle. Companies like Xinwangda, deeply rooted in the battery and energy storage sectors, are well-equipped to navigate this new challenge.

This mobile energy storage vehicle is set for mass production in May 2025, transitioning into more application scenarios and serving a broader range of power users. Xinwangda has already established a presence in five major sectors: power storage, industrial and commercial storage, residential storage, network energy, and smart energy. Its cutting-edge energy storage cells and large-capacity energy storage systems are among the first to be applied in the industry. In line with its commitment to meeting diverse energy needs across various sectors, Xinwangda continues to explore and uncover more possibilities in energy storage.

The Xinjiyuan 2000 exemplifies the integration of diverse application scenarios and charging technologies, embodying Xinwangda’s vision of supporting industries in achieving a comprehensive transition to a green and low-carbon future. With its innovative features such as large capacity, high power, and first liquid cooling system, it sets the stage for a new era in mobile energy storage.
