Parameters
What is air cooling?
The basic principle of air cooling technology is to take away the heat generated by battery cells through flowing air, thus keeping the battery temperature within a reasonable range. As a heat transfer medium, air can achieve heat exchange through natural convection or forced convection.
Natural convection:Natural convection refers to the phenomenon in which air flows by itself due to the difference in air density caused by temperature differences.In some cases, natural convection can be used to achieve simple thermal management, but this is usually not sufficient to meet high-intensity or high-density energy storage requirements.
Forced convection:Forced convection is to accelerate air flow through fans or other mechanical devices, thereby improving heat exchange efficiency.In container energy storage systems, forced convection is usually used to achieve effective thermal management.

Yes, by adopting the "Cell to Cell" active balancing and cluster level cluster management technology, the system efficiency is improved by 1% and the capacity utilization is higher.
Adopting a multi-mode liquid cooling control strategy, auxiliary power consumption is reduced by 20%, and the annual PUE is better, especially suitable for high-density and continuous charging and discharging conditions.
Can smooth out fluctuations in photovoltaic/wind power output and improve dispatchability; Cooperate with a 100MW power station to increase the consumption rate of new energy by about 20% and reduce wind and solar power curtailment.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
