Abstract
The thermal simulation analysis of a liquid-cooled energy storage battery pack was conducted at room temperature,and the results were compared and analyzed against thermal test results obtained under the same working conditions.The simulation parameters were adjusted to match the technological level,ensuring the error between the simulated and experimental values at measurement points remained within 1℃.Using these parameters,thermal simulations of the battery pack were performed under extreme environmental conditions of high and low temperatures.In the high-temperature scenario,the battery cells reached their final discharge state,while in the low-temperature scenario,they remained in a static state.The calculations indicate that the average cell temperature under high-temperature conditions was 39.2℃,with the highest temperature recorded at 41.2℃.Conversely,the average cell temperature under low-temperature conditions was 7.8℃,with the lowest temperature at 3.7℃.These findings indicate that the liquid-cooled battery pack can maintain cell temperatures within the normal operating range,even in extreme environments.The thermal simulation method outlined in this study offers a comprehensive approach to analyzing the battery pack's thermal state under extreme conditions,providing an avenue to assess the thermal performance of the energy storage system when experimental costs are prohibitive,or conditions cannot be replicated.关键词
