Battery Pack High and Low Temperature Water Cooling Testing System

The battery pack high and low temperature water cooling testing system is a cooling unit specially developed and produced by Aoxu Zhaochen for the energy storage industry. With the development of new energy technology, the application of containerized energy storage systems in new energy, photovoltaics, and power stations is gradually increasing. The high performance and high stability technical requirements of the cooling system of dedicated containerized energy storage systems are also being emphasized.

1、 System core architecture

　　Battery Pack High and Low Temperature Water Cooling Testing SystemAdopting modular integrated design, consisting of five core modules:

　　Container type machine roomProvide integrated physical installation space with protective performance to ensure stable system operation.

　　Battery Management System (BMS)Real time monitoring of battery status, intelligent management of charging and discharging processes, and providing safety protection.

　　Battery pack temperature control systemAs the core of heat dissipation, it covers components such as chillers, pipelines, air conditioners, and air ducts to achieve precise temperature control.

　　Energy Storage Converter (PCS)Efficiently convert AC/DC electrical energy and achieve flexible energy allocation in energy storage systems.

　　fire protection systemEquipped with professional fire extinguishing devices to build a solid defense line for the safe operation of the system.

Among them, the chiller, chiller pipes, air conditioning, and air ducts in the temperature control system cooperate with each other to create a stable and suitable environmental temperature for the container energy storage system, ensuring the performance of each component.

2、 Heat dissipation mechanism

During the operation of containerized energy storage systems, lithium battery systems BMS、 Components such as energy storage monitoring generate a large amount of heat due to changes in current. For different working conditions, the system adopts a graded heat dissipation strategy.

　　routine operating conditionsThe air conditioning refrigeration system dissipates heat through air ducts to improve the overall ambient temperature.

　　High load operating conditionsStart the dedicated water-cooled chiller unit and directly cool the battery cluster through coolant circulation to ensure efficient operation of the system.

Taking the distributed energy storage power system as an example, the internal fan coil unit directly adjusts the local temperature, the refrigeration unit provides a cold source, and the cooling tower supplies cooling water to the refrigeration unit, forming a closed-loop heat dissipation system and effectively improving heat dissipation efficiency.
