Abstract: With the rise of new productive forces, the popularity of new energy vehicles is increasing and the importance of battery safety is becoming more prominent. The risk level during the battery pack assembly process is much higher than after installation and how to ensure the intrinsic safety of the battery pack assembly production process is a crucial issue that all car manufacturers need to focus on. This article takes the battery assembly accidents in the past five years as samples from the global events reporting tool of the author's company. It summarizes the main types of power battery assembly accidents and analyzes the reasons for accidents during the battery packaging process. Based on two typical accident cases, this article discusses and proposes design improvements from the perspectives of assembly process technology and the product (battery pack) itself, aiming to achieve intrinsic safety of operations, equipment and products as much as possible during the production process.

Key words: battery safety; intrinsic safety; battery pack assembly; equipment safety; risk control
