在“双碳”目标推动下，光储充一体化电站正成为新能源领域的热点。但你是否知道，电站内部的能量传输方式直接影响运营成本与收益？目前主流方案包括交流耦合与交直流耦合。本文将带你了解SUNDRE闪得能源如何通过交直流耦合技术，实现效率的显著提升。

In the pursuit of “dual carbon” objective, integrated photovoltaic-storage-charging stations have emerged as a promising solution. However, the energy transfer method within a station greatly impacts its operating costs and revenue. Currently, AC coupling and AC/DC coupling are the two mainstream approaches. Let’s explore how SUNDRE gains an edge with its advanced AC/DC coupling technology.

一、能量传输的“直路”与“弯路”

传统交流耦合方案中，光伏、储能、充电桩都需要经过多次交直流转换，导致能量损耗、效率降低。而SUNDRE闪得能源采用的交直流耦合技术，为直流电打造了一条“直达通道”，光伏、电池与直流充电桩可直接高效对接，大幅减少转换环节，提升整体效率。

In traditional AC coupling schemes, photovoltaic systems, energy storage devices, and charging piles all require multiple AC-DC conversions, leading to energy loss and reduced efficiency. SUNDRE’s AC/DC coupling establishes a direct DC pathway, enabling efficient energy exchange among PV, storage, and DC chargers with minimal conversion.

二、效率对比：交直流耦合表现更优

在典型的光储充电场景中——无论是光伏直接充电、经储能充电，还是电网补电——SUNDRE闪得能源的交直流耦合方案均展现出更高的效率。相比传统交流耦合，其平均效率提升约2%，让更多能量真正用于充电，而非损耗在途中。

In common charging scenarios—whether from solar, storage, or grid—SUNDRE’s AC/DC coupling consistently delivers higher efficiency. With an average improvement of about 2% over traditional AC coupling, more energy is directed to charging rather than being lost during conversion.

三、效率提升带来实实在在的经济效益

这2%的效率提升意味着可观的电费节约。以一个配备11把充电枪的场站为例，日均充电200度，电价0.6元/度，10年预计可节省近10万元。这不仅提升了运营收益，也为环保作出实质贡献。（注：以上计算基于典型设备效率与假设工况，实际节省可能因具体设备性能、运营策略及环境因素而有所不同。）

This 2% efficiency gain translates into significant cost savings. For a station with 11 charging guns, with an average daily charging of 200 kWh and an electricity price of 0.6 yuan/kWh,operating over 10 years, it could save nearly 100,000 yuan in electricity costs. This not only boosts profitability but also supports environmental sustainability.(Note: The above calculation is based on typical equipment efficiency and hypothetical working conditions, and the actual savings may vary depending on the specific equipment performance, operation strategy and environmental factors.)

四、结语

SUNDRE闪得能源通过交直流耦合技术，构建高效直流母线，优化能量流动路径，降低系统损耗，代表光储充电站向更高效、更经济、更绿色方向发展的重要一步。选择SUNDRE闪得能源，就是选择长期可靠的高效运营与持续收益。

By implementing AC/DC coupling technology, SUNDRE establishes an efficient DC bus that optimizes energy flow and reduces loss. This approach represents a key step toward more efficient, economical, and sustainable PV-storage-charging stations. Choosing SUNDRE means investing in long-term, high-efficiency operation and steady returns.
