I've recently noticed new trends in electric vehicle thermal management technology—liquid cooling systems are becoming more integrated, with module-level and even cell-level cooling now mainstream. The industry is starting to discuss proactive early warning mechanisms for "thermal runaway," using AI chips to monitor cell temperature fields and electrochemical impedance changes in real time. Compared to traditional air cooling, the combination of liquid cooling and phase-change materials can increase heat dissipation speed by over 30%, but cost and weight control remain challenges. Additionally, 800V+ high-voltage platforms impose stricter requirements on insulation materials and sealing processes. What do you all think about the feasibility of this technical path?
Has there been another breakthrough in electric vehicle thermal management technology?

What are the mainstream manufacturers doing to meet the strict insulation and sealing process requirements for 800V high-voltage platforms?
I'm really optimistic about this technical approach. A while back, I studied a paper on liquid cooling systems and found that managing heat at the module level can indeed keep the temperature difference within the battery pack under 2°C, extending battery life. However, cost and weight are definitely major drawbacks. Mainstream liquid cooling plates on the market currently cost nearly 1,000 yuan each, so if production scale doesn't pick up, manufacturers will likely hesitate. I suggest testing it first in high-end models and gradually introducing it to the mass market once the technology matures.
