Since 2025, with the gradual abolition of mandatory energy storage requirements for new energy projects at the national level and the accelerated nationwide rollout of electricity spot markets, the traditional peak-valley arbitrage model for commercial and industrial energy storage has faced a dual challenge: shrinking profit margins and intensifying homogeneous competition. The industry is currently evolving from a mere "peak-shaving and valley-filling tool" into a "power asset capable of participating in multiple market transactions." The core of this transformation lies in establishing a revenue framework—through technological upgrades and the restructuring of operational models—that encompasses a diverse range of electricity market mechanisms.

Many people know that energy storage is the golden opportunity in the new energy sector, but few people understand that the most certain and stable growth segment in the next 10 years is not grid-side giant energy storage, nor residential energy storage, but industrial and commercial energy storage (referred to as "commercial and industrial storage") – that is, energy storage systems installed for industrial and commercial users such as factories, shopping malls, data centers, and hospitals.

In energy storage and microgrids, the Energy Management System (EMS) acts as the "brain" that coordinates all devices, and its communication architecture directly determines system performance. The mainstream solutions are divided into "master-slave architecture" and "distributed architecture," which differ significantly in their core concepts.

Air-cooled and liquid-cooled products each have their own advantages. Looking ahead, energy storage thermal management will evolve towards higher energy efficiency, smaller temperature differences, and integrated multi-thermal management, driving innovation in system-level solutions.

Against the backdrop of accelerated energy transition in Europe, the industrial and commercial electricity market is exhibiting a significant trend of increased price volatility and widening peak-to-off-peak price differences. This creates considerable economic opportunities for energy storage systems. This change is primarily driven by multiple factors, including the surge in renewable energy installations, fluctuations in traditional energy prices, and the evolution of electricity market mechanisms.

This article will focus on important concepts such as charge and discharge efficiency, off-grid switching time, and cycle life in the field of energy storage.
