日本語

太陽光発電と車載用中古リチウム電池を組み合わせ、資源制約地域の温室灌漑・空調を自立運用する国家プロジェクトの実証研究。適応制御型BMSにより電池寿命を7.8〜9.3年延長し、最大3.3kW放電と熱制御偏差0.3%以内を達成。空気中の窒素を肥料化する技術も統合し、系統連系・自立マイクログリッド双方で実証、1システム当たり年約1.28t-CO2削減を報告する。

English

A national project integrating solar PV with second-life EV lithium batteries for off-grid greenhouse irrigation and climate control in resource-limited areas. An adaptive BMS extends battery life by 7.8–9.3 years, achieves 3.3 kW peak discharge and keeps thermal deviation within 0.3%. Air nitrogen fixation supplies fertilizer, and field tests of grid-connected and stand-alone microgrids show ~1.28 t-CO2 reduced per system per year.

📄 Abstract（原文）

The research demonstrates a national project combining solar photovoltaics with second-life automotive lithium batteries for local-scale agricultural irrigation and greenhouse climate control. The auto-opening greenhouse system can adapt to various climate conditions in resource-limited areas. Applying in-house battery management system (BMS) based on adaptive control algorithm, it allows real-time monitoring and prediction of critical parameters such as effective capacity and safety, ensuring safe operation and longer battery life. Results show that, with optimized management, the lifespan of second-life batteries can be extended by an additional 7.8–9.3 years, achieving a maximum discharge power of 3.3 kW while keeping thermal control deviations within 0.3%. Both grid-connected and stand-alone microgrid setups have been successfully tested in the field, improving local energy independence and reducing reliance on external power sources. In addition, to avoid the harm of chemical fertilizers to the environment, air nitrogen fixation technology is employed to extract nitrogen fertilizer from the air to irrigate crops such as tomatoes and cucumbers. The control system uses solar power to store electricity in batteries daily to provide nitrogen fixation and basic greenhouse needs, and can maintain greenhouse operations without relying on power grid. This work offers a practical, scalable model for low-carbon agricultural energy solutions, reducing carbon emissions by about 1.28 metric tons of CO2 per system each year. It provides a framework to guide policies, promote low-carbon transitions, and support global sustainable development goals in underserved areas.
