Movable walk-in chamber for testing secondary batteries
The patent US11982685B2 describes a movable walk-in chamber designed for testing secondary cells, featuring a thermally isolated enclosure with a walking aisle and dual racking systems along its long sides. This configuration allows for the insertion and removal of multiple secondary cells, with the capacity to accommodate at least 500 cells simultaneously. The chamber includes multiple cycler interfaces on its outer walls, each equipped with power and cell interfaces to facilitate the connection of secondary cells to testing cyclers. The design also incorporates cabling that connects these interfaces to a central power connector, enabling efficient power management and testing operations.
Additionally, the chamber is equipped with a control arrangement that can be managed via a central user interface, allowing for real-time monitoring and control of the testing process. The system includes various sensors to gather environmental data, which can influence the operation of the cyclers and climate control mechanisms within the chamber. The modular design of the walk-in chamber allows for stacking or side-by-side arrangement of multiple units, enhancing its versatility. Features such as secure locking mechanisms for the entrance and openable doors for easy access to the racking further contribute to its functionality, making it a comprehensive solution for secondary cell testing in controlled environments.
