Technical BackgroundIn 2026, China’s cumulative installed capacity of new-type energy storage has exceeded 100 million kilowatts, marking the industry’s Year of Value. As the core control unit of energy storage systems, the Battery Management System (BMS) relies heavily on high-performance CHIPSENSE...... READ MORE
Looking back from 2026—the inaugural year of the "15th Five-Year Plan"—the EV charging industry has long since left behind the "wild west" era characterized solely by a fierce race to maximize the sheer number of installed charging piles. Accompanying this evolution is the large-scale application of...... READ MORE
IntroductionModern variable-frequency air conditioners widely employ Permanent Magnet Synchronous Motors (PMSM) to drive their compressors; the core vector control algorithms utilized in these systems impose stringent requirements on the performance of the current sampling system. Open-loop Hall-eff...... READ MORE
IntroductionAs the core component of a photovoltaic (PV) system, the performance of a PV inverter directly impacts power generation efficiency. Current sensing is critical for achieving high-efficiency Maximum Power Point Tracking (MPPT) and ensuring safety protection. While traditional shunt-based...... READ MORE
Energy—particularly non-renewable energy—has historically been a fiercely contested resource; indeed, a review of history across different eras and regions reveals that a great many wars have been waged primarily over energy. Amidst the current volatile international landscape, geopolitical tensions...... READ MORE
The Little-Known "Reality" Behind First PlaceOur country has established the world's largest electric vehicle (EV) charging network. According to data from the National Energy Administration, as of the end of January 2026, the total number of EV charging points (including charging piles and guns) in...... READ MORE
Abstract: Addressing the issue of poor consistency among retired batteries in energy storage stations utilizing a cascaded-use strategy, this paper proposes a high-precision current monitoring solution based on the specifications and characteristics of the FR1C H00 series fluxgate current sensors fr......
