Frequent Energy Storage Thermal Runaway Incidents

Understanding liquid cooling energy storage begins with exploring energy storage temperature control technology. This approach is critical for preventing issues like capacity degradation, shortened lifespan, and thermal runaway in energy storage systems.

Energy storage systems contain numerous high-capacity batteries that require efficient thermal management. Without proper temperature control, battery performance, capacity, and lifespan can decline significantly. In severe cases, this may lead to thermal runaway, causing safety incidents.

From 2011 to 2021, there were 32 reported fires and explosions at energy storage power stations worldwide. Between January and May 2022, over 10 similar incidents occurred globally, with battery thermal runaway identified as a leading cause. These events underscore the importance of advanced energy storage temperature control to ensure the safe operation of power plants.

Liquid Cooling: The Future of Energy Storage Temperature Control

Energy storage temperature control technologies include air cooling, liquid cooling, heat pipe cooling, and phase change cooling. Air cooling removes heat through air convection, while liquid cooling uses heat transfer liquids like water or ethylene glycol. Heat pipe and phase change cooling are less practical and remain largely experimental.

Liquid cooling systems typically consist of components such as cooling plates, liquid cooling units (with optional heaters), pipelines (with temperature sensors and valves), high- and low-voltage wiring, coolants, and coolant pumps.

Compared to air cooling, liquid cooling offers superior heat dissipation efficiency, faster cooling, and better temperature regulation among batteries. These advantages lower energy consumption and extend system lifespan, ultimately reducing the lifecycle cost of energy storage systems.

Although air cooling currently dominates in domestic energy storage systems, the growing demand for high-capacity and high-rate energy storage makes liquid cooling solutions more suitable for large-scale or high-temperature applications. As new energy power stations and off-grid energy storage systems require greater battery capacity and power density, the adoption of liquid cooling is expected to rise.
