摘要：
CTB（cell to body）battery baody integration technology has great advantages in improving en⁃ durance mileage，vehicle stiffness and crashworthiness，which has become a new development direction of the new energy vehicle industry. However，sealing is one of the biggest problems that restrict the development of CTB tech⁃ nology in order to integrate the upper cover of the battery pack with the floor of the vehicle body. So far，there is still no research in the field of CTB sealing in the industry. This paper carries out studies in terms of CTB sealing strate⁃ gy，sealing structure design，sealing component selection，failure consequence analysis and user condition design verification，and puts forward solutions to the CTB sealing design problems in the industry for the first time ，so as to accelerate the popularization and application of CTB technology，and promote the electrification transformation of the global new energy vehicle industry. © 2023 SAE-China.
