AI Technical Summary
Technical Problem
Existing battery systems in vehicles are susceptible to large loads being exerted on adjacent battery stacks during collisions due to the transfer of force through cooling members with lower rigidity, potentially causing damage.
Method used
The battery system is designed with flexible busbars that connect battery stacks, allowing them to deform and absorb forces during collisions, reducing the likelihood of large loads being exerted on adjacent stacks.
Benefits of technology
The flexible busbars effectively absorb collision forces, minimizing the impact on adjacent battery stacks and reducing the risk of damage during vehicle collisions.

Abstract
The present invention provides a battery system and electric vehicle in which adjacent battery stacks are less likely to exert a large load on each other when a collision occurs between vehicles. [Solution] The system comprises multiple battery stacks 61, 62 arranged in the space below the vehicle's floor panel 25, each having multiple battery cells 70, and a flexible bus bar 80 that electrically connects two battery stacks aligned in the front-rear direction of the vehicle.
