At present, China’s new‑energy heavy‑truck market has passed the inflection point of large‑scale development. Industry data show that sales reached 137,800 units in the first three quarters, with market penetration exceeding 24%. Coupled with policies in many regions—such as bans on fossil‑fuel‑powered vehicles in mining areas and preferential access for green‑electric heavy trucks—electrification of heavy trucks has moved from high‑level strategic planning to concrete industrial implementation. As the energy‑replenishment stage remains the key bottleneck hindering the widespread adoption of electric heavy trucks, the choice of technological pathways has drawn intense industry attention. The comparative advantages and synergistic development trends of two major approaches—ultra‑fast charging and battery swapping—are becoming increasingly evident. Ruisu Intelligent Technology, a manufacturer with end‑to‑end capabilities across the entire value chain of charging and energy‑storage equipment, leverages its core R&D expertise and comprehensive service offerings to deliver integrated solutions for heavy‑truck electrification that combine cost‑effectiveness, efficiency, and reliability.
Comparison of Ultra-Charging and Battery-Swapping Technologies: A Core Trade-Off Between Cost and Efficiency
In the development of a new‑energy heavy‑truck energy‑replenishment technology framework, the two approaches—ultra‑fast charging and battery swapping—exhibit distinct business logics and cost structures. Their core differences lie in two key dimensions: the scale of capital investment and the management of full‑cycle operation and maintenance costs.
The battery‑swap model prioritizes maximizing energy‑replenishment efficiency and operates under a capital‑intensive business model. Its core costs stem from building an end‑to‑end battery‑cycle ecosystem, which requires substantial investment in spare battery packs as well as bearing the full lifecycle operation and maintenance expenses—covering critical functions such as temperature‑controlled warehousing, battery performance testing and maintenance, and cross‑regional logistics coordination. In essence, this approach leverages heavy capital investment to achieve improved energy‑replenishment efficiency.
Ultra‑fast charging mode addresses the core needs of energy supply. Since battery assets are always configured alongside the vehicle, there is no need to manage battery‑related operations, thereby eliminating the burdens associated with full‑cycle management of spare batteries at the source. As megawatt‑class ultra‑fast charging technology continues to mature, energy‑replenishment efficiency has achieved breakthrough improvements, while also offering notable advantages such as simplified charging infrastructure and controllable post‑deployment O&M costs—making it better aligned with the industry’s current priorities for investment efficiency and streamlined operations.
Ruisu Intelligent Energy‑Replenishment Solution: Backed by end-to-end industry‑chain technology, it builds a four‑dimensional optimized energy‑replenishment system.
Leveraging its full‑chain manufacturing capabilities in charging and energy‑storage equipment, Ruisu Intelligent has launched a comprehensive ultra‑fast charging and energy‑replenishment solution for heavy‑duty trucks, centered on the solid‑state transformer (SST). This solution seamlessly integrates energy‑storage technology with intelligent control systems, establishing an efficient, cost‑effective, and stable energy‑replenishment framework that achieves four‑dimensional optimization—comprehensive coverage, simplified architecture, high‑efficiency replenishment, and superior operational performance—specifically including:
1. Dual-path energy replenishment deployment
To accommodate diverse operational scenarios, Ruisu offers two solutions. Solution One: Utilizing grid power as the primary energy source, the system employs a solid-state transformer to match voltage levels and optimize power quality before charging the mobile energy storage unit. This mobile storage vehicle features a high‑capacity 4.18 MWh battery and fast‑charging capabilities, enabling flexible deployment at various job sites for precise energy replenishment. Additionally, it can leverage off‑peak nighttime electricity rates to further reduce operating costs. Solution Two: A solid-state transformer facilitates efficient medium‑to‑low voltage conversion and flexible voltage regulation, paired with high‑power, multi‑interface charging terminals that enable simultaneous fast charging of multiple heavy‑duty trucks. While enhancing energy‑replenishment efficiency, this solution also supports advanced cost optimization through an intelligent scheduling system.
2. Core Technology Support
By replacing conventional transformers and power‑conversion equipment with solid‑state transformers (SSTs), the entire power‑conversion chain is fully digitized, effectively mitigating fluctuations in renewable‑energy output and ensuring reliable supply to meet instantaneous high‑load charging demands, thereby laying a stable foundation for the deployment of megawatt‑scale ultra‑fast charging networks. Coupled with mature immersion‑type liquid‑cooling technology, this solution addresses thermal‑management challenges and safety concerns in high‑power charging scenarios, enabling constant‑temperature control throughout the battery’s lifecycle and fundamentally eliminating the risk of thermal runaway. At the same time, it can extend battery life by more than 30%, safeguarding project investment returns and long‑term operational reliability.
3. Core Performance Advantages
The solution supports megawatt‑class high‑power charging, delivering an efficient energy‑replenishment capability of 100 km of range in just one minute. By adopting a modular, high‑frequency, and DC‑based design philosophy, it reduces land‑use by 15% and lowers the required grid capacity by 20%. The system achieves a peak efficiency of 97.5%, more than 5 percentage points higher than conventional AC‑charging solutions, thereby significantly optimizing the operational cost structure.
Reliable, all‑scenario compatibility: end‑to‑end service support, empowering diverse operational use cases.
Ruisu Intelligence has seamlessly transferred its mature, end-to-end industrial-chain technologies and refined management capabilities—previously validated in large-scale energy-storage projects—to the heavy-truck charging domain, establishing a highly adaptable and reliable system‑support framework. This solution is broadly compatible with complex operational scenarios such as port logistics, mining‑area transportation, and long‑haul freight, with specific assurance capabilities including:
1. Extreme Environment Adaptability: Through a modular structural design and enhanced system performance, the product achieves a high protection rating and operates across a wide temperature range, ensuring stable operation under harsh climatic conditions and in weak grid environments, thereby effectively overcoming environmental constraints on energy‑replenishment services.
2. Full‑Lifecycle Operations and Maintenance Services: Leveraging an intelligent O&M management platform, we have established an asset‑protection system that shifts from “reactive emergency repairs” to “proactive early warning.” This enables real-time monitoring and diagnostics of equipment operating conditions, precise prediction of potential risks, and timely intervention to ensure the long-term stable operation of energy‑replenishment facilities.
Joining hands with Ruisu Intelligence to co-build a new green energy ecosystem.
Electrification of heavy-duty trucks is a key pathway for the transportation sector to achieve its “dual carbon” goals, and the maturity of the energy‑recharging infrastructure directly shapes the industry’s development trajectory.
