Movable walk-in chamber for testing secondary cells
The granted patent (Publication Number: US11982685B2) describes a movable walk-in chamber designed for testing secondary cells. The chamber includes an enclosure with short and long sides, forming thermally isolated temperature chambers. It features a walking aisle, racking for inserting and testing secondary cells, cycler interfaces with power and cell connections, and cabling to connect cyclers to a central power source. The design allows for efficient testing of multiple cells simultaneously, with the ability to control cyclers through a central user interface.
Additionally, the movable walk-in chamber includes features such as communication interfaces, energy recovery capabilities, modular design for stacking chambers, attachment mechanisms for cyclers, and temperature/climate control mechanisms. The enclosure is divided into partitions to create multiple temperature chambers, with sensors providing data on the test environment for control purposes. The design also includes secure locking mechanisms, openable doors for easy access to cells, and a walking aisle between the racking along the vertical walls. Overall, the patent outlines a comprehensive solution for testing secondary cells efficiently and effectively within a controlled environment, enhancing the testing process for various types of cells and configurations.
