Liquid Cooling Container Energy Storage System
The cabinet adopts an integrated design to meet the space requirements of each module, and the space is reasonably arranged to arrange various parts in the cabinet. Since the liquid-cooling unit is independently designed and manufactured, the space occupied by the liquid-cooling unit is greatly reduced, giving the unit a certain advantage in size; the main body of the cabinet is designed with all welding molding, giving the frame a higher strength, which provides a guarantee for the carrying capacity of the cabinet.
The liquid cooling unit is completely independently designed and manufactured, which greatly improves space utilization while meeting the performance requirements, making the liquid cooling unit smaller than similar products; the cooling performance design leaves a margin to ensure that the equipment can operate under special working conditions. It can still operate safely and stably; at the same time, the unit uses a combination of fluorine system and natural cooling system to provide cooling capacity, making the unit have significant energy-saving effects under long-term operation conditions throughout the year.
We have long been focusing on the research, development, production and sales of new energy power equipment such as solar energy and energy storage.

Module
The battery pack adopts an intelligent liquid cooling temperature control system which includes a liquid cooling unit, pipeline system, and liquid cooling plate structure in each battery module. The pipeline system is composed of primary, secondary, and tertiary pipelines and control valve groups to achieve a balanced distribution of liquid cooling medium.
Every single battery pack of this project uses the standard liquid cooling box, which adopts a pressure-die-casting structure integrating the battery case together with the liquid cooling plate to achieve compactness. Meanwhile, the design also ensures that the coolant is physically isolated from the battery, eliminating the risk of coolant leakage into the battery pack, and improving the safety and reliability of the system.

BMS System
The protection and monitoring functions of the battery system are realized by the Battery management system (BMS), which is adopted with a three-level network architecture:
BMU (module level, built into the module):
Monitors the voltage and temperature of a single cell, and the total voltage of a single pack, and through CAN protocol, the above information is transmitted to the upper-level BlS in real-time, which can control the voltage balance of the single cell.
BCU (rack-level, built-in high voltage box):
Detects the total voltage and current of the cluster batteries, passes through the protocol, and transmits the above information to the upper-layer BNS in real time. it can display the capacity, health status power of the battery when charging and discharging, and the power prediction and calculation of internal resistance
SCU (system-level):
Collects lower-level BCU information to monitor battery remaining capacity and health status forecast in real-time. Communicates with the upper and external systems via RS-485 or Modbus-TCP/P.
Liquid Cooling Cabinet
The overall structure of a single battery pack is shown in the following Figure. The liquid cooling flow passage is integrated into the bottom plate of the box, which not only reduces the height of the whole pack but also realizes the dry and wet separation between the coolant and the battery cell, ensuring the safety of the system.
A single battery cluster consists of 9 battery packs stacked on the rack from bottom to top, as shown in the Figure below. There are 44 x 9=396 battery cells. The liquid cooling pipelines between the nine battery packs are all in parallel, so that the water temperature at the inlet of all battery packs is consistent, which is conducive to reducing the temperature difference inside clusters. The container-level thermal management system is shown in the following Figure. The liquid cooling flow passages for all battery packs are connected in parallel. The system uses customized refrigeration units. The total flow is evenly distributed to each battery pack to meet the heat dissipation requirements of the battery pack.
Thermal Management System
Adopting scientific fluid design, in the liquid cooling panel, piping, and mainframe system, have carried out a targeted design to ensure that the container's internal ambient temperature is controlled at 15 °c -35 °c, and the temperature difference is not more than 5 °c.

Pack Level Fire Suppression System
The battery container system adopts battery module level immersion protection automatic explosion-proof exhaust device + Novec1230 automatic fire extinguishing system + water sprinkler multiple progressive fire extinguishing protection system. The system includes an early warning device, an automatic fire extinguishing device, an exhaust device, and a fire sprinkler device. The alarm or air exchange function is started by detecting fire information and combustible gas concentration through an early warning device and, at the same time, automatically starts the fire extinguishing device to extinguish the fire completely after triggering the spraying conditions.
The whole process of battery container system safety prevention and control is divided into three levels of protection, as follows:
•In the first stage of protection, the thermal runaway of the battery is mainly suppressed in the battery module. In this stage, the possible malrunaway can be effectively suppressed in the early stage through the real-time monitoring of the cell level temperature and the submerged fire extinguishing function of the battery module. This protection level has high fire suppression reliability, and the protection efficiency can reach more than
90%.
•In the second stage of protection, when the fire fails to be effectively controlled by the first-level protection, the thermal runaway spreads to the container. The temperature sensor, smoke sensor, and combustible gas detector in the container will automatically start fire-fighting functions such as explosion-proof exhaust ventilation or gas injection fire extinguishing (with clean extinguishing agent Novec 1230) according to the detection situation. The fire extinguishing process can minimize secondary losses.
•In the third stage of protection, when the second-level protection function fails to control the fire in the container, the water sprinkler system is started
and the full coverage sprinkler is carried out in the container to ensure that the thermal runaway in the battery container is controlled and does not spread
