1. Basic product definition The 261 energy storage cabinet is an All-in-One outdoor liquid-cooled integrated industrial and commercial energy storage system. The standard specification is 125kW power and 261kWh usable electricity. It uses lithium iron phosphate batteries. The whole machine integrates battery clusters, BMS battery management, PCS energy storage converters, EMS energy management, liquid cooling temperature control, multi-level fire protection, power distribution protection in a single cabinet, IP55 outdoor protection, modular pre-installation, and can be connected to the grid on site. It is the mainstream standardized energy storage equipment for industrial and commercial, charging stations, and optical storage and charging projects. 2. Core structure and technical advantages 1. The integrated architecture is safely separated into upper and lower compartments, and the battery compartments and electrical compartments are arranged in different areas. The front maintenance is small, and complex civil construction is avoided; multiple cabinets are supported for AC parallel capacity expansion. A single cabinet to ten cabinets can be combined with 1.25MW/2.61MWh energy storage power station, adapting to different power consumption scales. 2. Liquid cooling precision temperature control is equipped with AI liquid cooling and heat dissipation. The cell temperature difference is controlled within ±2℃, which is far superior to traditional air cooling. It greatly improves battery cycle life, supports wide temperature outdoor operation of-20℃~50℃, and adapts to high-temperature factory areas., open-air charging station environment. 3. Multi-level safety protection cell/PACK/cabinet/PCS four-level electrical protection, combined with PACK level aerosol + fully submerged water fire protection, top directional explosion relief, EPO emergency shutdown, insulation detection, lightning protection, over-temperature, over-current, short-circuit self-locking, multiple redundancies to avoid the risk of thermal runaway. 4. The intelligent cloud control system has a built-in EMS energy scheduling host, equipped with touch screen and 4G/Ethernet communication, and the cloud monitors voltage, current, cell temperature, and SOC power in real time; it supports remote fault alarm, automatic adjustment of charging and discharging strategies, and unattended operation and maintenance. 3. Core product uses 1. Industrial and commercial peak-valley arbitrage, reduce energy storage and charging during low electricity prices, discharge during peak hours to replace power grid electricity, and reduce peak electricity bills; accurately match the 2-hour charging and discharging conditions, make full use of the daily electricity price difference, and shorten the investment payback period. 2. Demand management, reduce basic electricity bills to alleviate the impact of high-power loads in factories and charging stations, reduce peak transformer demand, avoid high demand fines from power supply bureaus, optimize plant distribution capacity configuration, and reduce investment in transformer expansion. 3. The emergency uninterrupted backup power supply network switches to off-grid mode instantly when the power is cut off, providing continuous power for production equipment, charging piles, monitoring, fire protection, and machine rooms to ensure that critical loads do not stop. 4. Photovoltaic self-use and consumption of excess electricity are combined with photovoltaic modules in the factory to store surplus photovoltaic power during the day and release it at night to improve photovoltaic self-use rates, reduce photovoltaic grid losses, and achieve integrated energy conservation in light storage. 5. The charging station is equipped with integrated optical storage and charging to adapt to new energy charging stations to suppress the instantaneous impact of high-power charging piles and relieve the pressure on transformer expansion; store electricity at low troughs and quickly charge piles at peak supply, reduce the power cost of the station and improve the continuous output of charging piles. ability. 6. Participate in virtual power plants and assist power grid revenue response power grid dispatch in milliseconds. You can access the virtual power plant platform to provide frequency modulation, voltage regulation, and load regulation services, and generate additional peaking subsidy benefits. 7. Off-grid microgrid power supply Kuangqu, parks, and remote areas without commercial power are independently networked, and combined with diesel generators and photovoltaics form a stable microgrid to ensure continuous power supply. 4. Applicable scenarios Industrial parks, commercial complexes, logistics parks, new energy charging stations, photovoltaic power stations, office buildings, hospitals, data rooms, Kuangqu, bus stations, and small and medium-sized distributed energy storage projects. 5. The supporting power distribution front end can be equipped with GGD low-voltage distribution cabinet to realize total incoming line, shunt protection, metering and reactive power compensation. The 400V three-phase grid on the AC side of the energy storage cabinet is connected seamlessly with the power distribution system in the station., forming a complete optical storage, charging and distribution system.
