Description

Technical Field

[0001] This utility model relates to the technical field of coolant filling equipment, specifically to an automatic coolant filling device for a liquid-cooled energy storage system. Background Technology

[0002] Energy storage systems are technologies that store energy in a medium for future use. They consist of energy storage devices, control systems, inverters, sensing systems, thermal control systems, and auxiliary equipment. Energy storage devices mostly consist of battery packs and supercapacitors. When using energy storage devices to store electrical energy, a thermal control system is typically used to control the temperature of the battery packs in the system to improve their efficiency and lifespan. Thermal control systems generally use either air cooling or liquid cooling. Liquid cooling, due to its higher cooling efficiency and faster cooling cycle, is widely used in various large-scale energy storage systems. It utilizes the interaction between the coolant and the stored energy. The circulating heat transfer of the liquid cooling plate inside the energy storage device performs circulating liquid cooling to cool the device. After the heat is transferred, the coolant flows back to the circulating cooling equipment for further cooling and reuse. During the circulation and cooling process, the coolant will inevitably be lost to some extent. Therefore, it is necessary to add coolant regularly to ensure the quantitative and saturated capacity of the internal coolant. However, the existing coolant lacks a filtration mechanism during filling, which makes it easy for impurities to be added into the device, causing inconvenience to users. To address this, we propose an automatic coolant filling device for the liquid cooling energy storage system. Utility Model Content
