Frontiers | Research and design for a storage liquid refrigerator
Aiming at the pain points and storage application scenarios of industrial and commercial energy, this paper proposes liquid cooling solutions.
Much like an automobile passenger might experience “ear popping” while traversing mountainous terrain, battery enclosures experience similar pressure fluctuation as elevation changes. You May Like...
The variation in internal battery pressure is closely related to critical issues such as thermal runaway, mechanical deformation, and lifespan degradation. The non-uniform distribution of internal pressure may trigger localized hot spots or even thermal runaway, posing significant threats to vehicle safety.
Pressure dynamics, however, serve as critical indicators of internal battery states, directly reflecting thermal stability and mechanical integrity, thereby playing a pivotal role in BMS functionality. Consequently, integrating pressure monitoring into BMS architectures is imperative for comprehensive battery management.
Based on the periodic pressure variation characteristics of batteries, this study selected three key parameters—initial pressure, peak pressure increment, and average pressure rise rate per cycle—to characterize mechanical stress evolution.
