AI Technical Summary

Technical Problem

The inverter units in energy storage containers are not convenient for wiring and maintenance, and the battery clusters have a short service life due to temperature.

Method used

The inverter unit is located at the bottom of the battery cluster, and the battery pack is located at the top. It is cooled by a liquid cooling system, with a check valve controlling the flow of coolant. An air cooling system is used to dissipate heat from the inverter unit. A drawer-type installation structure is designed for easy maintenance and cooling.

Benefits of technology

It facilitates the installation and removal of the inverter unit, reduces the impact of temperature on the battery cluster, extends the battery's lifespan, and reduces coolant waste and safety hazards.

Abstract

This utility model relates to the field of energy storage devices, and more particularly to a liquid-cooled high-voltage cascaded direct-connected energy storage structure system. Battery packs are located at the top of each battery cluster, and inverter units are located at the bottom of each battery cluster. The battery packs are connected in series via busbars. The battery packs are connected to the charging unit via busbars, and the charging unit is connected to the power unit via busbars. The liquid cooling system includes primary and secondary pipelines, with the primary and secondary pipelines connected together. The battery packs are connected to the secondary pipelines. The liquid cooling system is used to cool multiple battery clusters. The advantages of this utility model are: since the inlet and outlet of each battery pack are connected to the pipelines via check valves, when a battery pack needs to be disassembled or installed, simply closing the corresponding check valves one and two effectively prevents coolant leakage. This not only avoids coolant waste but also reduces potential safety hazards caused by liquid leakage.
