Employing a modular design, these systems allow users to flexibly expand battery capacity according to household electricity demands. Their battery cells achieve high-voltage output through series connection, effectively reducing current losses and enhancing overall energy efficiency. When integrated with photovoltaic systems, they efficiently store surplus solar power generated during daylight hours, releasing it during night-time or peak consumption periods to significantly reduce household electricity bills.
The 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system is engineered for businesses that demand high power output and long-duration capacity in a single, weatherproof enclosure. By pairing a 250 kW power conversion system with 522 kWh of usable lithium-ion storage, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system delivers four hours of continuous discharge at rated power, making the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system ideal for peak-shaving, tariff arbitrage and micro-grid support. Unlike conventional air-cooled cabinets, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system uses a non-conductive dielectric fluid that circulates through every battery module, keeping cell temperature deviation below 2 °C across the entire 522 kWh pack. This thermal precision extends cycle life beyond 8 000 cycles and allows the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system to operate safely in ambient conditions from –30 °C to +55 °C without derating.
The system adopts high-quality holmium phosphate power cell, which brings better performance and reliability; each battery module unit is equipped with an independent high-performance BMS system for scientific management of the battery cell; the battery module unit supports parallel connection for expansion; it supports a variety of inverter communication matches; and the large battery storage module adopts a standardized 19-inch viewing rack design, which is easy to install and widely used in a variety of application scenarios such as home, store, office and so on.
