Its core functions include: energy storage: storing grid or photovoltaic power through internal battery packs (such as lithium-ion batteries); power distribution: controlling charging and discharging via an energy management system (EMS) and a power conversion system (PCS); and multi-scenario power supply: supporting power supply to loads such as electric vehicle charging stations and industrial equipment. This type of product is essentially a mobile microgrid hub, requiring a balance between ease of transport, environmental adaptability, and system security. Existing containerized battery packs are densely arranged at the bottom of the container, but the ventilation system is mostly a top-mounted single-fan design, leading to short-circuiting of hot and cold airflows, and temperatures exceeding 60°C in the bottom battery area's heat dissipation dead zone.
