View moreKehua's Milestone: China's First 100MW Liquid Cooling Energy Storage Power Station in Lingwu. Explore the advanced integrated liquid cooling ESS powering up the Gobi, enhancing grid flexibility, and providing peak-regulation capacity equivalent to 100,000 households' annual consumption.
The integrated liquid cooling ESS is complicated, rather than an easy-peasy assembly, hence it requires an enterprise to be extremely capable of integration, and demands carefully selected batteries and components, as well as full consideration of safety, O&M, transportation etc.
Meanwhile, the nuclear-grade 1500V 3.2MW centralized energy storage converter integration system and the 3.44MWh liquid cooling battery container (IP67) are resistant to harsh environments such as wind, rain, high temperature, high altitude and sand, ensuring a safe, reliable and advanced power station.
However, for high-power fast charging and superfast charging, active liquid cooling that combines pumps and coolants (such as water and dimethyl silicone oil) needs to be used . In addition, the phase-change heat transfer technology of coolants also should be introduced as the charging power increases in the future [12, 13].
The principle has been widely applied and recognized in fields such as helical-tube-type heat exchanger [35, 36], and microchannel heat sinks [37, 38]. Currently, the maximum power of super-charging stations can reach 500 kW, and the maximum current load on the charging cable core is 500 A (Endesa X Ultra-fast pantograph, as per Table 1).
For example, Brakelmann and Anders compared influences of the two liquid cooling methods on the circuit capacity of 230-kV cross-linked polyethylene cables using a numerical model. They found that when the temperature of conductors is in the range of 50–85 °C, the direct cooling shows a better effect than indirect cooling.
