Performance evaluation study of secondary power products under different thermal environments

To accurately evaluate the performance of secondary power products in thermal environments, this study adopts an experimental analysis and validation-based research approach. Performance testing of secondary power products is conducted under two temperature conditions: simulation design value conditions and extreme offset temperature parameter conditions (specification value conditions). The corresponding test results are recorded separately. Through comparative analysis of the product's performance variations under these two temperature conditions, the study explores the impact of temperature fluctuations on product performance. This research aims to provide a scientific and reliable method for comprehensively assessing the performance stability and adaptability of secondary power products in different thermal environments, offering a theoretical foundation and technical support for future product optimization and practical application.
